2004年6月9日 · The negative dBs that you're seeing simply indicate that the amplifier is putting out sound at some level that is below its 0 dB reference level. If you're at -20 dB, then you're 20 dB below the reference level, or 1/100th the loudness of reference level. How loud that actually is depends on where your amp's reference level is.

2009年5月2日 · The relation of dBs and distance can also be used to help determine how loud that 110dBs might be at say twice the distance. This falls under the inverse square law. Basically, all you need to know is that in a reflective-free environment, if you double the distance you lose 6dB of sound pressure.

2006年11月16日 · What are DBS & VDP inputs on a Receiver for? I'm 'guessing' they stand for Digital Broadcast Satalite and Video Digital Processing Basically I have a Denon AVR 2807 that has inputs for DVD, VDP, DBS, VCR1, VCR2 and CDR/Tape.

2005年2月25日 · Subwoofer amps I see only have gain level and hertz usually from 0 to 240hz I say keep the sub at about 60-80hz and gain level half or 3/4 of the power gain.

2005年4月19日 · What is the task? All copper is best for interconnects but I'd go with RG59 for that. Dish, CATV and antenna connections do fine with good old dual shielded, copper coated steel cables unless you're in the shadow of a transmission tower or have a run over 300'.

2015年6月2日 · Hi, My understanding is that a 3 way splitter labeled with -4, -4 and -8 db ports is not lower quality or lossier than a splitter labeled with 3.5, 3.5, and 7 db ports. Could someone please confirm or refute? Thanks, b

2015年2月9日 · Using a Y adapter may add a few dbs to the subwoofers's output. Some claim that the subwoofer works better at lower levels with the Y-cable. The auto-off mode of some older subwoofers (e.g, Velodyne CH-12) may not come on at lower levels without the use of a Y-cable.

2021年4月5日 · Hey guys, I'm wondering what kinds of modifications most people like to do to Audyssey after the calibration. I know everybody is different... some people like Audyssey as is, and believe that it does a great job, other people like to bump subwoofer levels, center channel levels, add house...
