VII. Operating the 901 Equalizer Controls
The 901 Active Equalizer has a TAPE switch which replaces
the function of the TAPE MONITOR switch on your preamplifier or re­
ceiver if you have connected the Equalizer as described in Section V.
(The Equalizer connected to the tape monitor function on your preamp­
lifier or receiver.) In this case, the TAPE switch on the Equalizer is
used as described in your preamplifier manual. The TAPE MONITOR
switch on the preamplifier should be left in the MONITOR or IN posi­
tion permanently.
If the Equalizer has been connected as described in Section VI
(the Equalizer connected between your preamplifier and power amplifier),
then the TAPE switch on the Equalizer should be left permanently in the
NORMAL position. The function of the TAPE MONITOR switch on your
preamplifier has not been disturbed.
The Equalizer also features three program contour controls
that can be used to adjust for the program source, the acoustic proper­
ties of the room and personal taste. These controls are specifically
designed to offer flexibility not provided by any controls currently avail­
able on high fidelity equipment.
The response of the system is flat when all controls are in
the positions indicated by the dots. The effects of the remaining positions
are described below.
