Bose 901 Series III - Manual (Page 15)

If you wish to play your tape recorder without using the equal­
izer (for conventional speakers or headphones) and your con­
trol amplifier has two tape monitor circuits, an additional con­
nection procedure is required:
1 Connect "Y" connectors to both channels at Ihe tape output
connections of your tape recorder
2, Connect one side of each "Y" connector as described in
Steps 2 and 3 of Connecting Your Tape Recorder"
3 With the remaining output from each channel 'Y ' connector,
connect cables to the unused tape monitor input connec­
tions of Tape Monitor 2 found on your control amplifier
4 To play your tape recorder with your 901s. place the tape
monitor of your 901 equalizer in Ihe monitor position (in)
using the TAPE MONITOR 1 circuit.
6 To play your tape recorder with conventional speakers and
headphones, place the TAPE MONITOR 2 switch of your
control amplifier on. Your tape recorder will then be con­
nected directly to your high-fidelity system and will play
without the equalizer
B. CONNECTING HEADPHONES AND CONVENTIONAL
SPEAKERS
It is important to realize that the BOSE Active Equalizer intro­
duces substantial boost In the range below 100 Hz and above
4.000 Hz to match the power response of the 901 speakers
Consequently, conventional speakers or headphones, if played
with the equalizer in the circuit, will sound unnatural with both
treble and bass being emphasized
MORE IMPORTANTLY. HEADPHONES AND CONVENTION-
ALt SPEAKERS MAY ACTUALLY BE DAMAGED IF PLAYED
WITH THE ACTIVE EQUALIZER IN THE CIRCUIT.
For this reason, it is important to switch the Active Equalizer
out of Ihe circuit by placing the tape monitor switch of your con­
trol amplifier in the OFF or NORMAL position when playing
conventional speakers or headphones with your high-fidelity
system
