Worked for meIT has a role in the volume.I was Playing music and my speakers kept on shorting out, i smelled burning wires and i look in back of my subwoofers and there melted.But i dont know if your subwoofer is damaged or not.I've replaced the damn thing probably 8 times and the sub will work like new for awhile, but then maybe two weeks or a month later it's out again. I'm no electronics expert; is there anything I can do to prevent the thing from blowing again. Polarity change? Do I need a new one? It is a 18v zener. replace this and you should be back in business.Wire Diagram should have the information. Please Help Turning it either way does nothing, no volume number appears. Soft reset doesn't fix it. Any thoughts? I have the same problem. My volume is stuck at 24. I have tried soft-reset.among other things. One thread says to turn volume down to 00 then press for 10 seconds. I have no control over the volume, so, yeah, thanks for that fix. I found that I could get the volume down by unplugging it,plugging it back in and sometimes the volume would pop up and I could turn it down one notch. I did it till I got to 00.thought AHA! My problem is solved. No such luck. When I press the volume at 00 and try to hold it for 10 seconds, after 3-5 seconds it just pops back to the station frequency. I also thought that if I could get into the guts and spray the volume control with tuner-cleaner, it might help. No go.after taking off the cover, I found a bunch of REALLY delicate looking electrical tapes and wires.I was scared I would destroy something in an attempt to reach the volume control. I hate to trash this radio, the sound is awesome.great design on the speaker, NASTY design on the controls. I'd be VERY interested to know if anyone, anywhere, has found a fix for this. I think maybe my next step will be hitting it with a hammer.Answer questions, earn points and help others. http://apsara.ru/userfiles/bowtech-tomkat-manual.xml

From what I can tell through manuals the PV500 has a 100W amp and the CR57's should only need 10-75W of power. Does this sound like it may be a power issue. Thank you for the recommendations as well. The subwoofer and speakers are separate components and are different than a packaged computer type speaker setup. What happened to the amp. Look for a used stereo or AV receiver. We had a rack mounted amp that stayed with the old office. Speakers werent going to go to use so I grabbed them for my office. Follow up question to the speaker wire guide you attached. Can you double up speaker wire. Can you have two pairs of speaker wires going to one banana plug. All rights reserved Back to top. You are currently using an outdated browser.

As an STF-2 owner I obviously recommended that, and told him that he would be hard pressed to do better for the price. He has also heard the STF-2 at my house and was really impressed by it. Anyway he gave me a call a few days ago and asked about BA subs, I honestly know nothing about them so I figured I would ask here. Anyway he still wanted to get some input on BA subs so let me know what you think. Thanks. Don't get me wrong here -- I'm a huge fan of BA speakers (I own the VR-M series all around) but I'm not that big a fan of their subs. The PV-1000 is impressive for its small size, but at that price you could do so much better with an SVS or a Hsu for less money.As for the PV500, in my opinion, it has its place in a small room as a low frequency supplement to bookshelves or sats for most music (rendering the ensemble similar to a broad range floorstander), but is inadequate for LFE effects in HT. That said, BA sub or not, there are many people out there who are not interested in the same kind of bass output that those who frequent these boards are (we are a curious lot, aren't weJust my two cents. What’s critical to a sub’s performance is the size of the room it’s in. http://enbatielektrik.com/images/boston-pv350-manual.pdf

Thus his liking your sub would only be relevant if his listening space is the same size as yours, or smaller. I’ve never heard a Boston sub, but a small-driver, low-powered sub will only carry the mail in a very small room if you run anything resembling theater volumes. I’ve heard great things about its performance-per-dollar value. Regards, Wayne A. Pflughaupt Now, before you jump into the standard SVS is the best. I also own an SVS 20-39PCi. Since I don't watch my movies at reference volume, in most situations the Boston subs do a great job. Also, if you ask my wife, she will take the Boston any day. She hates the size of the SVS. So for the money, you can certainly do better than a BA in my opinion. Of course I havent heard your sub so I cannot say that about yours. However, my experience with BA has not been a good one. Also, I am not here to comment on size versus performance because I know that the BA are generally smaller (svs vs ba) - but so are a lot of other subs that I feel have better extension and spl than the one I listened to at that price range.If you can score one at b-stock price.

With a little practice and proper eye exercises and adjustments, you can work out your eyesight problems and get your brain to work for you in getting things done. You are able to determine how much your visual vision is deteriorating or not through doing an eye eye chart test. This is because individuals with visual difficulties can not see clearly, they are confused and can not focus on objects or else they do not know what they're seeing. They get bored easily and don't know anything.It is crucial that you be aware of the condition you have so that you can determine the best remedy for your own problems. A physician will provide you an eye test so that you can determine your eyesight conditions and help you to work with your vision eye chart. The vision process is very complicated and different from one person to another. Our eyes perform various functions that react to light, color and motion. The retinas are always changing and growing together with our brain as we age. That is why we need to use eye exercises and mental visualization to make sure our eye health is not being affected by any other problem we may have. People who have a lack of focus can have many motives as to why they are having vision issues. Occasionally it is since their visual system is now damaged, at times it is because they've had a stroke or brain surgery, and occasionally it's a hereditary disorder. It is the best thing that you can do to keep your eyes healthy and also be aware of problems before they get out of control. A visual system that's used does not work for everybody. A visual system which isn't working properly can become really bad and cause all kinds of problems for people that have vision problems. www.dantizuma.com/files/files/cardiovascular-and-pulmonary-physical-therapy-a-clinical-manual.pdf

It's essential to work together with your eye doctor with this so that you can develop the best vision eye picture for your requirements. You can even learn how to perform a vision eye chart on your own. Don't let your eye condition get worse and wind up with something serious. Discover how to restrain the eyesight issue and get on the right path to clear vision. How To Create A Fishbone Diagram In Excel 2020.

The experimenters concluded that there were differences in brain activity related to gaze- related attentional modulation. McCleery et al. (2009) presented low- and high-risk 10-month olds with pictures of familiar and unfamiliar faces and objects; components of interest included the N290, P400 and Nc. For the N290 and P400, there were no group differences in latency to faces (although there Luyster et al. Page 3 Brain Topogr. Author manuscript; available in PMC 2011 October 1. NIH-PA Author Manuscript NIH-PA Author Manuscript NIH-PA Author Manuscript The present investigation seeks to explore further the use of ERPs in improving our characterization of the early ASD endophenotype. Twelve-month old infants (at low and high risk for ASD) were shown familiar and unfamiliar faces, and the amplitude and latency of three relevant components—the N290, P400 and Nc—were explored in relation to group (high risk vs.We anticipated variability in laterality for the N290 and P400; that is, we expected a main effect of measurement location for both components, though not necessarily the same pattern of laterality for the N290 and the P400. On the other hand, we anticipated a main effect of familiarity for the Nc similar to that reported by Burden and colleagues (2007), such that amplitude would be larger for unfamiliar stimuli. Finally, based on previous findings (Elsabbagh et al. 2009; McCleery et al. 2009), we anticipated no group effects on the N290 or P400 but hypothesized that a group difference might emerge in the Nc amplitude. Methods Participants Participants were enrolled in an IRB-approved longitudinal, collaborative project between Children’s Hospital Boston and Boston University. Families with a child who is either typically developing or has a diagnosis of ASD and who also have an infant under the age of 6 months of age were recruited for study participation. dakotaterritorycustomhomes.com/ckfinder/userfiles/files/cardiotouch-3000-operation-manual.pdf

All parents were directly contacted by the Family Coordinator regarding involvement in the study and were screened according to a set of exclusionary criteria (gestational age of less than 36 weeks, time spent in neonatal intensive care, maternal steroid use during pregnancy, maternal diabetes or family history of genetic disorders). For the families with an older typically developing child, the Social Communication Questionnaire (SCQ; Rutter et al. 2003) was used to screen for ASD symptoms in that older child; if the total score exceeded 9, the family was excluded from participation. Similarly, if a typically developing child had any first degree relatives diagnosed with ASD, that family was excluded from participation. Informed consent was obtained at the time of the visit. Infants who completed a visit at 12 months of age were considered for inclusion in the present analyses. Data collection included behavioral and electrophysiological measures (described below). In addition, for families who were recruited on the basis of having an older child with an ASD, that child’s diagnosis was confirmed using standard cutoffs on the SCQ (Rutter et al. 2003). Note that because this is an ongoing longitudinal project, diagnostic outcome for the enrolled infants is not yet available for the entire sample reported here. One hundred and 55 children completed the 12-month study visit, and 109 provided adequate data for analysis (24 refused to wear the Geodesic net, the other 22 saw an insufficient number of trials to enter in data analysis). After hand editing and averaging (described below), a total of 32 children in the high-risk for ASD (by virtue of having an older sibling with an ASD) group and 24 low-risk controls (all of whom had a typically Luyster et al. Page 4 Brain Topogr. Author manuscript; available in PMC 2011 October 1. NIH-PA Author Manuscript NIH-PA Author Manuscript NIH-PA Author Manuscript An Early Learning Composite score (with a mean of 100 and standard deviation of 15) was calculated based on performance across four subscales: Visual Reception, Fine Motor, Receptive Language and Expressive Language. Both models wore a neutral expression and stood in front of a gray screen, with their neck and shoulders draped with gray cloth. For each infant, an unfamiliar face was chosen that was similar to the familiar one in ethnicity; images of mothers wearing glasses were paired with images of unfamiliar women wearing glasses. Images were cropped as needed to standardize face and image size. ERP Recording and Data Processing All ERP recording was completed in an electrically- and sound-shielded testing room with low lighting. Children were seated on their parent’s lap, approximately 65 cm in front of the experimental monitor. ERPs were recorded as participants viewed stimuli, presented for 500 ms each. Images were shown in random order, maintaining a 50:50 ratio. From a separate room, the examiner observed the participant’s eye movements and attentiveness through a hidden video camera mounted on top of the experimental monitor. Stimulus presentation (via ePrime software, Psychology Software Tools, Pittsburgh, PA) was initiated only when the child was attending to the screen, and any trial during which the child’s attention wavered was tagged and removed from further analysis. A maximum of 100 trials were presented. Continuous electroencephalogram (EEG) was recorded using a Geodesic Sensor Net (Electrical Geodesics Inc., Eugene OR) with 64 or 128 electrodes based on the child’s head circumference and date of session (due to an equipment upgrade 1 ), and referenced on-line to a single vertex electrode (Cz). The data were analyzed offline by using NetStation 4.4.1 analysis software (Electrical Geodesics Inc., Eugene OR). The continuous EEG signal was segmented to 1000 ms post-stimulus recording periods, with a baseline period beginning 100 ms before stimulus presentation. The segments were then digitally 1 The EGI electrode nets used in this project underwent an upgrade approximately 2 years after the project commenced, and all 64- channel sensor nets were replaced with 128-channel sensor nets. Luyster et al. Page 5 Brain Topogr. Author manuscript; available in PMC 2011 October 1. NIH-PA Author Manuscript NIH-PA Author Manuscript NIH-PA Author Manuscript After excluding segments with eye movements and blinks, the remaining segments were visually scanned by an experimenter blind to study group. Bad channels and other artifacts (e.g., off-scale activity, eye movement, body movements, or high-frequency noise) were identified. If more than 10 of the channels were marked as bad, the whole segment was excluded from further analysis. Finally, average waveforms for each individual participant within each experimental condition were generated and re-referenced to the average reference. Participants with fewer than 10 good trials per condition were excluded from further analysis. Peak amplitudes and latencieswere calculated for the N290 and P400 in the chosen time windows; this was not done for the Nc because of the diffuse nature of the deflection. Mean amplitude within the selected window was calculated for all three components. Ten posterior electrodes were chosen for the occipital-temporal components (N290 and P400), and fourteen frontal electrodes for the frontal component of interest (Nc); these electrodes were selected within equivalent scalp locations across the 64- and 128-channel sensor nets. Omnibus ANOVAs were conducted using Greenhouse-Geisser adjusted degrees of freedom, and when significant main effects were revealed, post hoc comparisons were carried out using t -tests with a Bonferroni correction for multiple comparisons. Results Behavioral Data Early Learning Composite standard scores from the Mullen Scales of Early Learning were compared across groups. Author manuscript; available in PMC 2011 October 1. NIH-PA Author Manuscript NIH-PA Author Manuscript NIH-PA Author Manuscript In order to explore within-subject differences in the Nc, the degree to which children in the low- and high-risk groups were differentiating across conditions was explored by calculating a difference score for each infant, in which mean amplitude in the familiar condition was subtracted from mean amplitude in the unfamiliar condition. The Nc is a negative deflection; therefore, in this calculation, a negative difference score indicates that the child exhibited the anticipated main effect of condition. That is, they exhibited larger mean negative amplitude to unfamiliar faces than familiar ones. Conversely, a positive difference score indicates that the mean negative amplitude was larger to familiar than to unfamiliar faces, a finding that is contrary to the expected result. Furthermore, because of the main effect of region found for Nc mean amplitude, this was done for each region (left hemisphere, midline, right hemisphere) separately. See Fig. 4 for distributions of difference scores by group and region. Each group was divided according to whether or not the anticipated response (greater Nc to unfamiliar than familiar faces) was demonstrated, and chi-square tests were used to explore group differences within region. Two-thirds of the low-risk sample (16 out of 24 children, or 66.7) showed the expected amplitude effect, whereas only slightly more than Luyster et al. Page 7 Brain Topogr. Author manuscript; available in PMC 2011 October 1. NIH-PA Author Manuscript NIH-PA Author Manuscript NIH-PA Author Manuscript Discussion By one year of age or shortly thereafter, infants at high risk for ASD have been found to show behavioral deficits in social development at increased rates, relative to their low-risk peers (Cassel et al. 2007; Nadig et al. 2007; Yirmiya et al. 2006). The present investigation addressed whether high-risk infants might also exhibit atypical neural responses to social stimuli. As anticipated, there was a main effect of location for the N290 and P400. However, the two components showed slightly different patterns of spatial distribution, consistent with prior investigations (Halit et al. 2004). The N290 was most negative over left hemisphere leads, a finding that is similar to a previous report of larger left activation in semi-medial electrodes in 12-month olds (Halit et al. 2003). The P400 was smaller over the left hemisphere than over midline leads, while there was no difference between midline and right hemisphere electrode groupings. These results are partially consistent with previous findings: on the one hand, it has been reported elsewhere that the P400 amplitude is reduced over the left hemisphere (Halit et al. 2003). On the other hand, it is generally thought that the P400 amplitude is maximal over the right hemisphere (de Haan and Nelson 1997; de Haan et al. 2003; Taylor et al. 2004), a finding that was not replicated here. It is worth noting that this study and the one reported by Halit et al. (2003) employed an average reference (recommended practice in the field, see Picton et al. 2000), whereas other references have been used elsewhere (e.g., linked mastoids in de Haan and Nelson 1997). Some of the variation in component characteristics across these studies may be associated with differing reference selection (for example, see Joyce and Rossion 2005). For the most part, the two groups showed similar responses in face-sensitive components. The N290 showed no differences in amplitude or latency associated with ASD risk, and the latency of the P400 was similar across groups. There was one unexpected finding: a trend towards a larger P400 peak amplitude in the high-risk group than in the controls. Interestingly, this finding did not carry through to the mean amplitude measurement. This finding is difficult to interpret, because it is not entirely consistent with previous reports that have noted group differences in P400 latency, but not amplitude (Elsabbagh et al. 2009; McCleery et al. 2009). It is critical to note, moreover, that previously reported differences in P400 responses have been in the context of slightly different tasks, which used images of objects or faces with direct vs.Another recent investigation reported that high-risk 10-month olds showed no differences from a control sample in social working memory (Noland et al. 2010), measured through the presentation of an examiner’s face. Interestingly, an emerging characterization of the early ASD endophenotype points to the importance of non -social processing in distinguishing these infants from their low-risk peers. Furthermore, Luyster et al. Page 8 Brain Topogr. Author manuscript; available in PMC 2011 October 1. NIH-PA Author Manuscript NIH-PA Author Manuscript NIH-PA Author Manuscript In sum, then, there is accumulating evidence across the current and previous investigations that the early ASD endophenotype may have less to do with social processing than originally supposed and more to do with non-social or object processing (see Tager-Flusberg 2010 for a discussion). Results for the Nc generally confirmed our hypotheses. First, we found that the Nc was more negative to unfamiliar faces than to familiar ones (similar to the 12 month olds reported by Burden et al. 2007) across both of our groups, suggesting that the infants were recruiting greater attentional resources for an unfamiliar face than for a familiar one.
