4. FRONT PANEL
Power Switch: Turns on the main power for the ampli-
fier. When the power is on, the LED will be illuminated.
5. BACK PANEL CONNECTIONS
Line Input: This line input is a sensing
input that will activate the DPA-1.2
when an audio signal is present. When
there is no audio, the amplifier will go
into standby or default back to the
whole-house amplified signal if playing.
Speaker Level Input: The speaker level input is a
sensing input that will automatically switch the DPA-
1.2 from the default input to the speaker level input.
This input would be used in place of the line audio
input. An amplified signal from a smaller amplifier or
television can be amplified by the DPA-1.2 for a
cleaner, more dynamic sound.
Gain Controls: Left and Right gain con-
trols independently adjust the sound
level for each channel. When in the
bridge mode, only the right control
is used.
Stereo / Mono Switch: The Stereo /
Mono switch selects stereo or mono for the speaker
outputs. In the Mono position, each Left and Right
output is Mono. The Mono portion is also used for
bridged operation.
Video Input: The Video Input is a sensing input that
will activate the DPA-1.2 when a video
signal is present. When there is no
video, the amplifier will go into standby
or default back to the whole-house
amplified signal if playing.
