Bose 901 Series III - Manual (Page 11)

THE FOLLOWING STEPS ARE PROVIDED TO ENSURE
THAT THE EQUALIZER IS PROPERLY CONNECTED TO
YOUR HIGH-FIDELITY SYSTEM
h Place the TAPE switch of the equaUzer in the MONITOR
position
As you slide the "frequency contour” controls from one
extreme to the other, you will detect a detent (identified
by a “dot" on the front panel). Place the TREBLE and
MIDBASS controls at this position. Set the "BELOW 40"
control In the "dotted" or out position,
i. Place the TAPE MONITOR or TAPE FUNCTION switch
of your control amplifier in the NORMAL or OUT position
j. Turn your system on. (Be certain that the equalizer is
plugged into the switched ac outlet of your control ampli­
fier and observe that the pilot light on the equalizer is on.)
k. Play the entire system as you normally would, using a
record player or AM/FM source to be sure it is operating
properly. (Do not use a tape recorder for this portion of
the test.)
I Turn the BALANCE control of the control amplifier to the
extreme left and right to check for proper connection of
the left and right channels (If the channels are reversed,
check your amplifier or speaker connections carefully.)
You have now tested the amplifier, wiring, and speaker sys­
tems. but not the equalizer, as it is not yet switched into
the system
If your system Is not functioning at this point, please go back
and check all connections, as any errors in connection of
your system must be corrected before proceeding further
m. With the system now playing, turn the TAPE MONITOR or
TAPE FUNCTION switch on your control amplifier to the
MONITOR or ON position The sound should stop. If the
sound does not slop, recheck Steps "a" through "I. "
n. Now. place the equalizer TAPE switch in the NORMAL
position. The sound should now return If the sound does
not return and the equalizer pilot tight Is on. then the
equalizer is probably connected incorrectly. Recheck
Steps "a" through "!."

PLIFIER MUST BE LEFT "ON" FOR THE ACTIVE EQUAL­
IZER TO BE IN THE CIRCUIT CHECK THE TAPE MONITOR
SWITCH PERIODICALLY TO MAKE CERTAIN IT IS IN THE
"ON" POSITION
