Q: Can I put more than one KEY amplifi er in my car?
A: Yes, however the Auto Setup program is designed to optimize the front-sound stage only. Only one KEY
amplifi er can use the Auto Setup feature.
Q: Can I use the KEY amplifi er in addition to a subwoofer:
A: Yes, but care must be taken. Make sure you disconnect your subwoofer prior to the Auto Setup process. The
subwoofer must stay quiet during the Auto Setup so the KEY amp can hear what the car speakers sound like
without interference.
Upon successful completion of the Auto Setup, you can reconnect your subwoofer and use the crossover
switches on the KEY amplifi er to apply an adequate hi-pass to your speakers in order to match them with your
subwoofer. If you've forgotten to disconnect your subwoofer and it plays pink noise during Auto Setup, the Auto
Setup program will quit with sad music and error code #6.
Q: How does the Crossover work on the KEY amp?
A: In case no Auto Setup has been done, or the Auto Setup process was for Full-Range speakers (most cases),
the 24dB/octave Linkwitz-Riley Hi-pass crossover will be applied to all speakers. This crossover is user-
selectable via DIP switches with the following options: OFF, 60 Hz, 80 Hz or 120 Hz.
In case of a Bi-Amp system with woofers and tweeters, the door speaker's hi-pass is user selectable and the
lo-pass is 3.2 kHz 24 dB/octave. The tweeter's hi-pass is also 3.2 kHz 24db/octave.
In case of a Bi-Amp system with door and dash woofers, the door woofer's hi-pass is user selectable and the
low-pass is 640 Hz 24 dB/octave. The dash woofer's hi-pass is 320 Hz 24db/octave. The overlap of 640 Hz
low-pass with 320 Hz hi-pass is done on purpose to enrich the mid-range. The Auto EQ takes care of trimming
excesses that can occur within this range.
Q: My Auto Setup program did not complete successfully, I am getting a sad song and beeps at the end. What
is it?
A: The beeps at the end are the error codes of the Auto Setup program. Upon failure, please count the number
of beeps after the sad song and troubleshoot with the information below.
Q: The Auto Setup process completed successfully, but I'm not happy with the sound. What other steps can I
take?
A: Ensure all speakers connected to the KEY amplifi er are wired in phase with each other. Be sure to check both
the amplifi er side and the speaker side of the wiring.
