Bass Level – Use the bass level potentiometers (pots) to increase the output level
between 50Hz and 150Hz. This is useful for compensating for poor bass cabinet
loading or high levels of low-frequency ambient noise. The Channel 1 and Channel 2
pots are active in all modes of operation.
Remote Volume – When using the amplifier to power one listening zone, connect the
remote control unit to the zone 1 (+) pin and the ground pin. Set the internal remote
volume switch (Figure 4) to 1_REMOTE. When using the AmPlus 100 amplifier for 2-
zone applications, connect a second remote to the zone 2 (+) pin and ground pin. Set
the internal remote volume switch to 2_REMOTE.

Line Outputs – Both line output responses are flat (regardless of whether or not you
have installed active equalizer cards). The remote volume control affects the line
output levels. Both outputs are active in stereo mode. Only zone 1 is active in dual
mono and mono modes.
Power Amplifier Outputs – The 70/100V output becomes active when the amp
mode switch is in the 70/100V position. In this setup, both AmPlus 100 amplifier
channels are bridged and provide up to 100W to the 70/100V speaker(s).
When the amp mode is in the 2-channel position and a jumper is placed across the
XFR CT pins, 50W is available at the 70/100V output and 65W is available at the
channel 2 output.
With the amp mode switch in the 2-channel position, both Channel 1 and Channel 2
supply 65W into a minimum load of 4 .
Internal High Pass Switch – When this switch is in the "HPF ON" position, frequen-
cies below 150Hz are attenuated at 18dB/OCT. This low-frequency roll-off occurs on
Channel 1 only. Use this switch for bandlimiting high-frequency speakers connected
to Channel 1 in a bi-amplified system.
