Troubleshooting

If the KEYLOC becomes frozen or stuck during algorithmic calculation, does
not appear to be working, or gives an error code, check the obvious things
first such as blown fuses, poor or incorrect wiring connections, incorrect
setting of gain controls, etc.
Tips for SETUP:
1. If you have issues getting a smoothed EQ response on an Real-Time
Analysis, go back and verify that the INPUT GAIN match of the KEYLOC is
set correctly. If there are tall peaking filters in your analysis, it can take two or
three sweeps of the GAIN MATCH track to ensure proper gain matching
(It's recommended to wait 10 – 15 seconds to make sure the gain match
LEDs are not flashing). If there's still an issue where the frequency response
is not being fully corrected, it is suggested to turn the input gain down ¼ of
a turn and run the KEYLOC setup process again.
2. If the issue persists, it is very likely that the output of your source unit is
being clipped. Use the GAIN SWEEP track and an oscilloscope on the
output of your source unit to verify that the signal coming from the source
unit is not clipping. If there is any clipping, slowly turn down the volume on
the source unit until all clipping is eliminated.
3. In most aftermarket systems in which you will not be using a fully active
DSP after the KEYLOC in the signal chain, you will likely want to turn off the
All pass/Time delay defeat for the best stereo imaging. See page 20.
4. To keep the noise floor (hiss) low, we have designed the KEYLOC to not
add more than 18db of gain to any one frequency. In most applications, this
should correct the frequency response to a nearly linear response of +/-
1.5dB in the frequency bands available.
5. During the KEY process, if you accidentally push the KEY button before
playing the NOISE FLOOR track, the KEYLOC will error out and all LEDs will
begin to flash. You must then press the KEY button to exit the KEY process.
Re-enter the KEY process to start again.
No power? With a Volt Ohm Meter (VOM) check the following: Π+12
volt power terminal (should read +12V to +16V)  Remote turn-on terminal
(should read +12V to +16V) Ž Check for reversed power and ground
connections  Ground terminal, for proper conductivity.
Power on, no signal? Check the following: Œ RCA connections  Test
audio source signal, either with a "known good" output device or other
means.
No or low output? ΠCheck the balance and fader controls on source
unit.  Check the RCA (or speaker input) and speaker output connections.
Ž Check the volume level on your source unit, to include the volume level of
any connected phones or MP3 players.
