Stereo/Mono Channel Operation:
The SE120 delivers 60 watts continuous average power per
channel into 8 ohms. It can be bridged for single channel
operation producing up to 120 watts of power into 16 ohms.
operation producing up to 120 watts of power into 16 ohms.
Input Mode Selector:
This switch will allow the user to specify the input signal to
the amplifier.
This switch will allow the user to specify the input signal to
the amplifier.
A. Stereo Mode:
This allows the right and left channels to reach their
designated amplifier channels. This mode will deliver
more than 60 watts into an 8 ohm load.
B. Mono Mode:
The SE1 20 can be operated in a bridged mode which drives
both channels with the same signal and combines to deliver
more than 150 watts into 8 ohms. This disables the right
channel input and routes the signal through the left channel.

Gold Plated RCA Input Connectors:
This provides the most accurate signal transmission and
lowest possible loss. Gold-plated terminals are immune to
signal deterioration with time that can be caused by corro-

Protection System:
The SE120 is equipped with a unique protection system
that constantly monitors the temperature of the output
devices and takes corrective action to prevent damage to
the amplifier as a result of excessive overheating.
