Hi,

I have a stereo frequency equalizer for sale.  It is made by BSR, and
the model number is EQ-3000.  I have had it for almost two years now,
and it has served me well.  I'm selling it because with a new amplifier
I bought I found that I'm not using it anymore.  The apparatus has two
major components -- the equalizer and a frequency analyzer.  I'm not
sure what specs are interesting about the analyzer, other than it has
5-10% accuracy depending on the frequency range.

Here are some specs for the equalizer:

	frequency response	5 to 100,000 Hz +- 1dB
	control frequencies	31.5, 63, 125, 250, 500,
				1k, 2k, 4k, 8k, 16k (Hz)

Some of the cool features is that it comes with a microphone, and the
analyzer has a pink noise generator.  That allows you to place the
microphone at the place where you usually listen to music, turn on the
pink noise (basically noise of same amplitude on every frequency), and
tune the equalizer to compensate for the room you're in.

The analyzer meter can be set to display left/right/both channels, and
has a hold feature.  The inputs to the equalizer include 2 tape decks
and a monitor source.  You can use the spectrum analyzer with or without
the equalizer.  The equalizer has also some settings for dubbing, which
is useful to copy tapes.

It also features a subsonic filter button, which attenuates the output
below 15Hz by -18dB/octave.  

Other than those, it seem to have all the standard features.  I'm asking
$100.00 for it, negotiable.

You can call me at 225-9493 (home), or better yet, send me email at
tompalka@mit.edu.
