C. CONNECTING THE EQUALIZER
IT IS MOST IMPORTANT THAT YOU FOLLOW THESE IN
STRUCTIONS FOR OPTIMUM PERFORMANCE OF YOUR 901
SERIES IV SPEAKER SYSTEM.
1. Using The Tape Monitor Circuit
The connection methods described in this section can be us
ed with virtually all Integrated ampiifers. preamplifiers, and
receivers.t Using the tape monitor circuit has two advan
tages: When using conventional loudspeakers or head
phones. the tape monitor circuit allows disconnection of
the Active Equalizer by turning off the tape monitor switch
on your control amplifier: this is important because conven
tional speakers and headphones should not be used with
the Active Equalizer. (See SECTION IV.) Also, optimum
system noise performance is obtained when connecting the
equalizer in the tape monitor circuitry.
When using this procedure, you should realize that the 901
equalizer is being connected to your equipment as if it
were a tape recorder, using the tape monitor connections
of your control amplifier.
NOTE: Check your control equipment to determine if your
unit has any additional switching flexibility. Some recently
introduced units now feature switching facilities called
Tape Monitor 3, External Equalizer/Processing. or Noise
Reduction Connections. The equalizer can be connected to
these terminals allowing greater system flexibility if re
quired.
fTo make connection easier, we are going to refer to all of these various com •
ponenis as the ”0001(01 amplifier."
Referring to FIGURE 4. connect the Active Equalizer accor
ding to the following instructions:
a. Turn off all power to your high-fidelity system.
b. If you have a tape recorder, disconnect it from your
control amplifier.
(Instructions in SECTION IV will tell you how to recon
nect your tape recorder to the system after the equalizer
has been installed.)
c. Using one of the cables supplied with the equalizer, con
nect the LEFT channel OUTPUT of the equalizer to the
LEFT or "A" channel of the tape monitor circuit of your
control amplifier. (This terminal may also be labeled
PLAYBACK or TAPE IN.)
d. Connect the RIGHT channel OUTPUT of the equalizer to
the RIGHT or "B” channel tape monitor connection of
your control amplifier.
e. Connect the LEFT channel INPUT terminal of the equal
izer to the LEFT or "A" channel TAPE RECORD connec
tion of your control amplifier. (This terminal may also be
labeled TAPE OUT or REC OUT.)
f. Connect the RIGHT channel INPUT connection to the
RIGHT or '‘B” channel TAPE RECORD connection of your
control amplifier.
g. Plug the ac power cord of the equalizer into a "switched'’
ac outlet on your control amplifier so that the equalizer
will automatically be turned on or off with the pov/er
switch of your equipment.
If the preceding steps are unclear, it may be due to the dif
ferent nomenclature used by various manufacturers of
amplifying equipment. Consult your control amplifier’s in
struction manual and refer to the section describing the
connection of a tape recorder. Remember, the equalizer is
connected just like a tape recorder.
