Factory Reset
Perform a factory reset procedure on the DSP amp using a small
flat head jewelers screwdriver.
Solutions:
•
With the amp powered OFF, carefully rotate the front panel
accessed 1L volume control fully-counterclockwise and rotate the
1R volume control to fully-clockwise.
•
Press the power switch to turn the amp ON.
•
Wait approximately 20 seconds for the reset to complete--power
switch LED on continuously.
•
Turn the amp OFF.
•
Reset the 1L volume control to maximum.
•
Turn the amp ON.

Channel Out
One channel of the amp does not have output.
Cause:
Line-level interconnect cable from the source to the affected
amp channel is loose, disconnected or faulty.
Solutions:
•
Verify that the interconnect cables are properly seated at both
the amp end inputs and source end outputs. Disconnect both
interconnects on the amp end (1L and 1R input connections on
the amp).
•
Connect the functioning channel’s cable from the source to the
non-functioning channel’s input jack on the amp (for example, if
1L is faulty, connect 1R’s cable to the 1L input jack and test).
•
Test playback to see if the speaker connected to the non-
functioning channel works.
•
If the affected channel is now working, the problem could be with
that channel at the source or with the interconnect cable for the
non-functioning channel.
•
Replace the affected channel’s interconnect cable and retest.
Test source on another audio system to confirm channel outputs
are functioning.
Cause:
Speaker wire leading out to the channel is loose, disconnected
or faulty.
Solutions:
•
Verify proper connection of the speaker wire at amp end
and speaker end. If the channel is still inoperative, disconnect
the speaker wire from the non-functioning channel at both the
amp end and speaker end. Connect a new, test speaker wire
from the affected amp channel output to the speaker or to a new,
test speaker. If the affected channel is now working, the problem
must be the speaker wire; replace with a new speaker wire. If the
affected channel is still not working, the affected channel in the
amp could be defective; contact DI Technical Support for
next steps.
Protection LEDs are Illuminated
One or more red protection LEDs are on.
Cause:
The problem could be DC on the input of the amplifier.
A short on the speaker wire going out to the zone.
A short at the speaker itself.
Solutions:
•
Disconnect the speaker wire from that channel going out to
the zone.
•
If the protection LED goes out, connect your local test speaker,
turn the amp back on and play music.
•
If the test speaker produces sound, then the speaker wire leading
out to the zone or at the zone speaker is shorted.
•
If the test speaker does not produce sound and you’ve tried a
different source on that pair of amp channels to rule-out a
defective source, then the amp requires service; contact Dana
Innovations Technical Support for additional instructions.
