CONNECTING TO A PREAMPLIFIER/POWER
AMPLIFIER SYSTEM
The MQ 101 is added to the circuit between the
preamplifier and power amplifier. Connect shielded
cables between the MAIN outputs of the preamplifier
and the MAIN inputs on the MQ 101. Connect
shielded cables from the MAIN outputs of the MQ 101
to the inputs of the power amplifier. The length of a
connecting cable is limited by its electrical capacit-
ance. The total capacity of each cable must not be
more than 1000 pF. For instance: Cables with 25 pF
per foot may be 40 feet long. The input impedance of
the power amplifier should be 47,000 ohms or more.
For best signal to noise ratio when using the MQ
101 between a preamplifier and power amplifier the
input attenuator switch on the back panel of the
MQ101 should be in the 0 dB position. When used
with preamplifiers that have bass trim controls it is
recommended that the bass trim controls be set in
the flat position.
