Troubleshooting

Problem
FiX doesn't turn on
Amps or processors
not turning on
Little or no bass
response
Low or no volume
Calibration Error
1 short red flash:
Calibrated re-
sponse not flat
2 short red flashes:
Incomplete audio
spectrum
3 short red flashes:
Delay compensa-
tion failure
4 short red flashes:
No/low input signal
level
Possible Cause
Faulty fuse
Poor connection integrity
Insufficient "+12VDC
(Switched)" input
Incorrect auto turn-on
mode settings
Poor connection integrity
Handsfree mode is
engaged
Reversed polarity at one or
more inputs
OEM source unit/master
volume set too low
Possible Cause
OEM source unit tone/EQ
controls not set flat
Reversed polarity at one or
more inputs
Disconnected or incorrect
input connections in
multi-way system
Poor connection integrity
Elevated OEM system
noise floor
OEM source unit volume
set too low
Valet mode is engaged
Too low or missing signal
from OEM outputs
Verify the OEM outputs
are "on". The OEM source
unit may need to "see" a
speaker load to turn the
amp "on".
Possible Solution
Remove fuse and check with continuity meter.
Replace if necessary.
Check "Ground" and both "+12VDC" connections
for pinched wires; ensure tight connections.
Make sure there is a sufficient +12V supply at the
"+12VDC (Switched)" connection; if not, a relay
may be required.
Verify "+12VDC (Switched)" and input signal
connections; refer to "Turn-On Mode" section.
Check "Remote Out" connections for pinched
wires; ensure tight connections.
Deactivate Handsfree mode using DRC-100, if
equipped.
Double-check wiring of "OEM Analog Inputs".
Increase OEM source unit volume; increase
DRC-100 master volume control, if equipped.
Possible Solution Before Recalibration Attempt
Verify OEM source unit tone controls are set to
zero/flat or "centered" and turn off any source
unit EQ or DSP modes.
Double-check wiring of "OEM Analog Inputs".
Connect input plugs, 1 pair at a time, and check
for green "Input Status" LEDs when playing
Calibration Track 01.
Use RTA to view output spectrum to identify
response gap for correction. Attempt to "Fill the
gap" by substituting a different L/R channel pair
and recalibrate.
Double-check "OEM Analog Input" plugs for
open or loose connections.
Disconnect any redundant input plugs already
carrying audio content available via other input
plugs and recalibrate.
Recalibrate at a lower (or higher) OEM source
unit volume setting.
Increase OEM source unit volume and recalibrate.
Ensure Valet mode is not active.
Make sure "Input Status" LEDs are green during
audio playback. With multiple inputs, insert input
connectors one plug at a time (input channels
1/2, 3/4, 5/6, 7/8) while playing a calibration test
signal and confirm both L & R "Status LEDs" are
green during playback.
May need to install a FiX-LSA-4 (sold separately)
to activate OEM amp outputs.
