All connections should be made to the
amplifier and double-checked before the ac
power cord is plugged in.
The power indicators will illuminate when the ac
power cord is plugged in and the power switch is in
the "ON" position.
OPERATION
General
The SMB-200 provides two modes of operation,
2-channel (100 watts per channel) or 1-channel mono
(200 watts bridged).
When the amplifier is in the 2 channel mode signals
are applied to both the channel A and B inputs.
Channel A and B outputs are connected to their
respective speaker loads. The output levels are
controlled by the channel input volume controls. In
the event that low frequency content is not required to
the speaker load, i.e. paging horns, the contour switch
may be operated to the ON position and frequencies
below 300 Hz will be reduced at a rate of 6 dBm per
octave.
When the amplifier is used in the bridge mode the
switch located on the back of the amplifier is
operated to the bridge mode position. The input
signal is applied to Channel A. The speaker load is
connected between the Channel A and Channel B 2
ohm output terminals. Channel A volume control is
used to adjust the volume level; of the speakers. In
the event that low frequency content is not required to
the speaker load, i.e. paging horns, the contour switch
may be operated to the ON position and frequencies
below 300 Hz will be reduced at a rate of 6 dBm per
octave.
PROBLEM
No output.
Distorted output.
Clipping lights are provided on the front of the unit.
These lights will illuminate when the output signal
exceeds the power rating of the amplifier.
There are 2 power lights located on the front of the
unit that will illuminate when the unit is connected to
a 120 Vac power source and the power switch is in
the ON position.
