Channel Out
One channel of the amp does not have output.
Cause:
Line-level interconnect cable from the source to the aected
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aected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aectedchannel’sinterconnectcableandretest.
 Testsourceonanotheraudiosystemtoconrm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aectedampchanneloutputtothespeakerortoanew,
 testspeaker.Iftheaectedchannelisnowworking,theproblem
must be the speaker wire; replace with a new speaker wire. If the
 aectedchannelisstillnotworking,theaected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 amplier.
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
dierentsourceonthatpairofampchannelstorule-outa
defective source, then the amp requires service; contact Dana
