Help AND Thanks IN ADVANCE!
The Audio Critic Magazine measured a Behringer A500 amplifier(test measurements made using Audio Precision Analyzer and PowerCube). I thought that people here would be interested in the results since it appears to be a superb value.
Of special note...
-bridgable to use a high power monoblock
-balanced and unbalanced inputs
-rock steady stability into 4 ohm loads and into highly inductive/capacitive loads(required for some rare difficult loads that many recievers may have problems driving)
-$180 street price!
Signal:Noise: -99dB
Crosstalk: -55dB
Frequency Response: -0.3dB @ 10Hz, -0.1dB @ 20Hz, 0.0db @ 1000 Hz, -0.2dB @ 10kHz, 0.6dB @ 20kHz,-2dB @ 40kHz
138 watts @ 8 ohms @ 1000Hz @ 1.000% THD+N, both channels driven
120 watts @ 8 ohms @ 20Hz @ 0.030% THD+N, 1 channel driven
120 watts @ 8 ohms @ 1000Hz @ 0.025% THD+N, 1 channel driven
120 watts @ 8 ohms @ 20000Hz @ 0.045% THD+N, 1 channel driven
220 watts @ 4 ohms @ 1000Hz @ 1.000% THD+N, both channels driven
180 watts @ 4 ohms @ 20Hz @ 0.056% THD+N, 1 channel driven
180 watts @ 4 ohms @ 1000Hz @ 0.050% THD+N, 1 channel driven
180 watts @ 4 ohms @ 20000Hz @ 0.050% THD+N, 1 channel driven
Harmonics of THD are primarily 2nd order, with subsequent harmonics approaching or under -100dB.
Power output was tested from 0 degrees phase resistive load(results given above) and into other phase angles up to +/- 60 degrees. Little variation of output voltage occured, regardless of phase angle.

So for an economical solution would this be recommended to use as an Amp for driving the lows on a pair of front speakers that are Bi-Amp capable? I hve or intend to have once it is all set up properly 7.1 with the new 3808 i just picked up. and want to Bi-Amp the front B&W's I also just picked up. The 138 wat into 8 Ohmx2 is relatively close to the Denon per channel specs. I was under the impression is was not a stereo 8 Ohm device (I am new to allot of this stuff. So what I assume usually is wrong
I have another question please, I really need advice for this as there is an aspect to this whole decoding thing that looses me.
I have a PS3 for Blu-Ray (I have an HD DVD player as well with similar issue).
1. I hear the PS3 is not DTS HD Master audio capable for decoding, nor is it capable of Bitstream output to send the audio direct to the receiver to allow the receiver do the decoding? True False on both counts?
To further this, I look into the PS3 BD Player settings and it has an audio setting and it says PCM and "Bitstream" huh?! So i dont get it, PLEASE EXPLAIN to a newbie in laymans terms for the most part.
What setting should it be on when I have a DTS Master BD Movie such as the New Simpsons movie? (Dont pick on my movie choices
I have two young boys)
The movie doesnt allow me to choose any other option in the movie settings for Dolby 5.1 for example. Just different languages.
The Receiver doesnt give me decoding options on Blu-Ray once the PS3 is turned on, the DTS and Dolby disappear, it just gives direct or standard and some other simulated options.
So basically...
We have 3 settings, The PS3, the actual movies settings, and the receivers settings.
Lat option question is this...I fit is a movie for Dolby HD Lossless aution should any of the above change? Will I be required to make changes based on each flick i watch?
Where do I start to ensure I am getting the proper sound.
Wow thats allot of questions, but I need to know, OCD compells me to learn and ensure I have all the info I need so I hope you are all pros willing to help a layman like me
Thanks IN ADVANCE
Happy Holodays
