![]() This was an exceptionally ambitious review, but one I was eager to start. An outboard amplifier, the BGA-2500, which is included with a pair of Radia R-800s, powers the two woofers. Each speaker has two 8-inch woofers mounted at the top and bottom, six Neo10 planar-ribbon midrange panels, and 16 Neo3PDR planar-ribbon tweeters in a vertical-line array pattern. With 24 drivers in each speaker, this giant stands almost 7 feet tall and is clearly designed for extreme listening-extremely satisfying listening, that is. I've reviewed many excel- lent in-wall speakers, but none quite like the new Radia R-800 in-wall speaker from BG. I was never the best solderer to start with and complements of my Mom's side of the family have a thing called essential tremors which cause my hands to shake when trying to focus on small tasks (fortunately not bad, but will get worse as I age more: the good news is the sole effect from it is you shake).Extreme audio: a new standard in transparency, definition, and detail. I ended up having to hit it with a small dremel.Ĥ) No laughing at my soldering. I used these, which can be found at ģ) I attempted to sand the case by hand where the XLR connector grounds to the case with zero success at removing the anodizing. PQG3FST112) that grounds to the case and fits, but requires that you solder a small jumper from PIN1. The Ghent case uses a larger spacing for the screw holes.Ģ) Switchcraft makes a connector (Part No. A few notes:ġ) I purchased Nutrik B series connectors only to find out when I went to use them they don't fit. I finally got around to correcting the PIN 1 wiring so it meets the Hypex/AES48 specification. The OP for this thread had indicated he had experienced a power down noise too, so not sure whether it is a design or a potential manufacturing issue, but there are plenty of good alternatives and so my search continues. If I had built the amp and discovered the transient, would have contacted Hypex, but was ready to move on. Warren did not seem as curious, but know he is busy, and appreciated the opportunity to try out his amp. While my inner scientist was curious, under the circumstances, did not plan to keep the amp. However, while it overemphasizes high frequency content, it presents a very well-behaved load to an amplifier. I will readily admit the speaker in question was the worst case. I did try some other speakers with varying results and you can find this earlier in this thread. Turned off the back panel switch and got same nasty pop. I was using Neutrik RCA to XLR adapters, so at this point, saw no point in testing with both speakers, so reduced the connections to a single speaker and shorted the rca input. He asked about my speaker sensitivity and suggested try shorting the input. He said he has sold 50 or more units of this model without complaint. ![]() Warren indicated he did not hear anything serious with the unit in his system, but did not detail how he tested. Was switching the power via the rear panel switch in all cases. I did not plan to use with any sources that have trigger capability, so unit was supplied without that feature. This VTV model is stereo and was not bridged. Not my first time to the rodeo, but since you chose this for your first post, I will oblige. Was the amp in stereo or bridged mode? Upon return was Warren at VTV able to reproduce the issue and inquire with Hypex? Sorry for all the questions but curious as Hypex are top performing amp modules excepting this issue.

Sorry for all the questions but curious as Hypex are top performing amp modules excepting this Sykora Any pop sound if speakers connected to amp but no input connected and power is switched? Was the input RCA (single ended) converted to XLR or XLR balanced? What was the source component driving the NC252MP-based VTV? Describe the power down sequences tried (source first, amp first), was pop sound always present and sounding consistent? How was the amp power turned off (rear power switch, 12V trigger removed, simultaneous with source, other). ![]() I anticipate most Hypex implementations would switch power in the same spot and hence Hypex would have considered this scenario and own responsibility for covering it. I'm also curious why there are some reports of power switching pops through the speakers. Frustrating experience but great to have VTV customer service. ![]()
