Inputs – The AmPlus 50 amplifier comes with two balanced inputs. They can be left

and right from a stereo source; two mono sources can also be mixed. Since the

AmPlus 50 amplifier is a single channel amplifier, a stereo source is internally summed

to mono.

Level – Channel 1 level adjust – This potentiometer (pot) controls the signal level of the

Channel 1 input source.

Channel 2 level adjust – This pot controls the signal level of the Channel 2 input

source.

Bass Gain – Use the bass gain pot to increase the output level between 50Hz and

150Hz (affects 50Hz – 150Hz only). This is useful for compensating for poor bass

cabinet loading or high levels of low-frequency ambient noise.

Remote Volume – Connect the remote control unit to the zone 1 (+) pin and the

ground pin.

EQ 1

Power Amplifier Outputs – The 70/100V output is active when the amplifier Mode

Switch is in the 70/100V position. The 4 output is active when the amplifier Mode

Switch is in the 4 position.

Internal High Pass Switch – When this switch is in the "HPF ON" position, frequen-

cies below 150Hz are attenuated at 18dB/OCT. Use this switch for band-limiting high-

frequency speakers in a bi-amplified system.
