Q BASS PLUS
On PC4800 and PC6600 amplifiers, we've taken bass control
to a higher level with QBASS PLUS
(labeled 1 and 2) on the front end of the amplifier allow you
to select one of four frequency centers - 30Hz, 36Hz, 44Hz
and 60Hz. The Q SELECT switch determines the width of
boosted frequencies. A 'Q' of 2 (switch out) will give you a
wide boost while a 'Q' of 4 will boost a narrow range of
frequencies. (See chart below.) On the rear end panel you
will find the QBASS PLUS
for an optional QBASS REMOTE
level control clockwise for up to 18dB of boost at your
selected frequency and Q.
