6. C ONNECTING HEADPHONES AND CONVENTIONAL
SPEAKERS
It is important to realize mat the BOSE Active Equalizer ir
troduces substamial boost in the range below tOO Hz an
above 5,000 Hz to match the power response of the 90
Speakers. Consequently, conventional speakers or headphone;
If played with the equalizer in the circuit, will sound unnaturi
with both treble and base being emphasized.
MC^E IMPORTANTLY. HEADPHONES AND CONVENTIONAL
SPEAKERS MAY ACTUALLY BE DAMAGED IF PLAYED WITI
THE ACTIVE EQUALIZER IN THE CIRCUIT.
For this reason. It is important to switch the Active Equalize
out of the circuit by placing the tape monitor ewitch of you
control amplitler m the OFF or NORMAL position when piayin
conventional speakers or headphones with your high-fldeiit
system.
