BI-AMP MODE: The majority of systems require
this switch to be OFF. Turn ON only if your speakers
are wired in "Bi-Amp" mode (refer to BI-AMP
operation picture on
to be specifically used without passive crossovers.
Possible usages are with component speakers (two
woofers and two tweeters), or with door woofers
and dash speakers. Once the Bi-Amp switch is ON,
the KEY amp will automatically detect and apply Bi-
Amplification settings during the KEY Auto Setup:
• Woofers and Tweeters: 3.2kHz 24dB/oct High Pass for
the tweeters, 3.2 kHz low pass for the woofers.
• Woofers and Dash Speakers: 320 Hz 24dB/oct High
Pass for the dash-speakers, 640 Hz low pass for the
woofers.
COMPRESSION: Set to enable (EN) to turn Auto
Compression on, reducing high amplitude signals
above a certain threshold, giving a more consistent
listening experience and protecting your audio
system. Set to defeat (DF) to turn Auto Compression
off.
FADER: Leave the fader switch to ON if you are
running two sets of inputs (front and rear for example)
to the amplifier. Set the fader switch OFF if you want
to drive all channels from a single stereo input.
HI-PASS: Use the HI-PASS switches of the amplifier
to set the internal crossover. Choose a cutoff of 60Hz,
80Hz, 120Hz, or OFF depending on the configuration
of switches.
