How to turn off Bose equalizer

Uhhhh....
Is there a way to turn a Bose 901 equalizer off? I have a pair of speakers plugged in to the "B" output on my amplifier, but the equalizer messes with the sound. Would unplugging the EQ do the trick? It's hooked up to the Pre In and Pre out on my amp, if that makes any difference.

on the series 1 EQ there is a normal/monitor switch that removes the EQ circuit from the tape loop.
 
My Technics SU-G90 doesn't have a tape monitor. Also, I've tried switching the EQ to Normal, but that turns the speakers off too. The cables from the pre in and out are connected to the Amplifier Connections on the back of the EQ, would it work if they were connected to the tape recorder connections?
 
There is not a way built into the Bose EQ to set it to Bypass. The assumption is that the EQ is installed in a tape or processor loop built into the amp in order to switch it in or out of the audio chain.

The EQ has no on/off switch. If you pull the plug on it with the Pre Out/Power amp In configuration, there will be no processing of the source signal through the Out/In loop.

@Kirk57: The Normal/Monitor switch was provided so that when the EQ was inserted into a Tape Out/Monitor loop, that specific function was not lost. That is, the loop itself is preserved through that set of jacks on the back of the EQ again so that it could still be used. BTW, the most common use for the Tape Out/In loops was for cassette or open reel tape decks used for recording off the FM or from an LP in the 'old-school' days.

@Crazy-in-az: What's the amp being used here?

Cheers,

David

I stand corrected. I was going on memory, which is always dangerous! :)
 
Well you can always manually move the plugs going from the eq output to your amp input to the bose tape output. This will bypass the eq.

Now if there was an easy way to switch the eq in and out you might accidentally leave th eq in for normal speakers. If you are lucky this will just caus distortion in the woofers an blow the fuse on the tweeters. If you are unlucky you might not have fuses on your tweeters.

Don't ask.
 
Ok, so little out there online about the rear panel layout so I have little to go on. Some amps of that era eliminated processor/tape loops to be cost-competitive.
