MP2 is a fucking VIDEO format - you MORON !!!!!!!!!!!

http://en.wikipedia.org/wiki/MP2

"MP2 or MP-2 may be:
MPEG-1 Audio Layer II audio codec and .mp2 files" etc etc

http://en.wikipedia.org/wiki/MPEG-1_Audio_Layer_II

"MPEG-1 Audio Layer II (MP2, sometimes incorrectly called Musicam) [1]
is an audio codec defined by ISO/IEC 11172-3. While MP3 is much more
popular for PC and internet applications, MP2 remains a dominant
standard for audio broadcasting.

MP2 began in the late 1980s as part of the ISO's Moving Picture Experts
Group (MPEG) effort to standardize digital audio and video encoding for
digital radio and TV broadcasting (DAB, DMB, DVB), and use on Video
CD.[2] The MPEG-1 standard, including the three audio "layers" (encoding
techniques) now known as MP1, MP2 and MP3, was finalized by the around
the end of 1992. MPEG audio was further promoted due to its Layer III
(MP3) component, which allowed for even lower bitrates."

You're confusing it with MPEG-2 which also delivers audio in addition to
video.

So Phyllis, you're simply WRONG WRONG WRONG !

** That is they are - from the factory.

YOU are NOT in any position to know how QSC set the bias current.

YOU have no proof WHATEVER of your MAD & WRONG assertion.

Stevenson is completely INSANE with:

1. Congenital autism.

2. Massive narcissism.

3. Manic personality disorder.

He tells massive lies, thousands of them.

It's possible the MXs do have some quiescent I don't think I measured that
back then. But the RMXs certainly don't.

Cos it is simply not true.

It can improve the THD performance though which is probably why they did it
in the RMXs.

In a conventionally biased amp there is a biasing transistor between the
two op bases

Actually in the voltage drive chain driving the bases and configured as a multiplier to
suit as many devices as may be on the heatsink (the drivers may be too - or the output
devices may be darlingtons).
which is thermally linked as closely as possible to the
output devices - this (to some extent) tracks the Vbe changes through a
slow bass cycle and maintains the bias point. In the QSC design, the
bias feedback circuit has been deliberately lowpass filtered so it can't
do this. So as the output devices heat up and cool down through a slow
cycle, the bias point will shift significantly.

They've messed about with it over the years. Check the RMX series which are still in
current production.

What really pisses me off are those companies including QSC who use a 1N4001 pressed up
against the heatsink with a dob of thermapath to do the sensing.. It's so amateurish.

Clearly you know nothing about amplifier design and the role of rapidly
changing gm in the output stage in the crossover area. Correctly configured,
the above technique helps enormously.

All you have to do is measure one of my D or E series amps. Or an AX series
even.

Inidentally, the 700D had a full power 1kHz THD of 0.008%. Better than many
hi-fi amps. In the AX I got it down to about 0.005%.

** YOU raised the issue of the QSC USA and MX models.

" Anyone that can't hear the distortion of QSC USA or MX series must have
severely damaged hearing.

The classic QSC arrangement with grounded collectors has no quiescent
current in the output devices. "


So now you admit you have never even seen one !!!

Technical Specifications

MPEG-1 Layer II is defined in ISO/IEC 11172-3

* Sampling rates: 32, 44.1 and 48 kHz
* Bitrates: 32, 48, 56, 64, 80, 96, 112, 128, 160, 192, 224, 256, 320 and 384 kbit/s

An extension has been provided in MPEG-2 Layer II and is defined in ISO/IEC 13818-3

* Additional sampling rates: 16, 22.05 and 24 kHz
* Additional bitrates: 8, 16, 24, 40 and 144 kbit/s

The format is based on successive digital frames of 1152 sampling intervals with four possible formats:

* mono format
* stereo format
* joint stereo format (stereo irrelevance)
* dual channel (uncorrelated) format

CAN do. It requires good design too. Certainly never been a problem for me. If
it's true that the MXs do have an idle current and I know the RMXs don't, that
could help explain why the RMXs have better specs.
