Bose 901 Series II - Manual (Page 9)

4. ALTERNATE METHOD HI
iUsing FOUR-CHANNEL DECODERS»
As previously stated, the BOSE Active Equalizer should be connected before the final stage of amplifica­
tion of the amplifier channels powering the 901 speakers. Additionally, the Equalizer should be connected
at a point in the signal path following the four-channel decoder to prevent any possible overloading of the
decoding equipment. Because of the many different decoders available, we suggest carefully reading the
owner's instruction manuals of all of the associated equipment regarding system connection. How you
connect the decoder will depend upon your own needs for control of the Equalizer and/or your associated
equipment.
D. CONNECTING A TAPE RECORDER
FIG.6
Since the Active Equalizer has been connected to what are normally the tape recorder terminals of your integrated
amplifier, preamplifier, or receiver, extra terminals are provided on the Equalizer for the connection of a tape
recorder. Follow the next five steps carefully: (Refer to Fig. 6.1
a. Turn all power off.
b. Connect the RIGHT channel TAPE IN terminal on the Equalizer to the RIGHT or "B" channel
OUTPUT terminal on the tape recorder.
c. Similarly, connect the LEFT channel TAPE IN terminal on the Equalizer to the LEFT or "A" channel
OUTPUT terminal of the tape recorder.
d. Connect the RIGHT channel TAPE OUT terminal on the Equalizer to the RIGHT or "B" channel
INPUT (or LINE IN] terminal of the recorder.
e. Similarly, connect the LEFT channel TAPE OUT terminal on the Equalizer to the LEFT or "A"
channel INPUT (or LINE IN) terminal on the recorder.
Installation of the tape recorder is now complete. To play the tape recorder, simply place the TAPE
switch on the 901 Active Equalizer in the MONITOR position (down).
CONTROL AMPLIFIERS HAVING TWO TAPE MONITOR CIRCUITS
Many modern preamplifiers, integrated amplifiers, and receivers have two tape monitor functions
providing the same monitoring features for two tape recorders instead of one. However, most of
these controls are constructed to prevent both monitoring switches from being turned on or
"activated" at the same time. Since the BOSE Active Equalizer must be in the circuit while the 901
speakers are being used, connecting the Equalizer in either TAPE 1 or TAPE 2 will require connecting
your tape recorder to the BOSE Equalizer tape monitor circuit, rw the unused TAPE monitor
position found on your control amplifier.
