ANSWER: Most speaker cabinets today are8-ohms.
For the sake of this question we will assume this is the
case. Youcan use a total of four 8-ohm speakers with
the KPM8420T: Two for the A power-amp and two
for the B power-amp . DO NOT plug all four
speakers into one power-amp.
ANSWER: Yes! One popular setting for vocal mics is to
use one digital effects section for reverband the other
effects section for delay. Here is an example: Set
Effects 1 to ECHO and Effects 2 to SMALL HALL.
Adjust the amount of reverbfirst by turning up the
EFFECTS 2 controlon the desired individual channel.
Then, add the desiredamount of ECHO by turning up
the EFFECTS 1 controlon the same individual
channel. Setlevels to obtain the desired effect.
ANSWER: Yes! This is one of the truly unique features
of the KPM8420T. Here is an example: a little Chorus
on an instrument can reallysweeten the sound, but
chorus effects on vocals area disaster. First set up the
Instrument channels: Setthe sound of EFFECTS 2 to
Chorus or Chorus/Rev in the master section of the
mixer. Turn up the EFFECTS 2 send on the individual
instrument channels to the desiredlevel. Now the vocal
channels: Setthe sound of EFFECTS 1 to one of the
reverbselections. Turn up the EFFECTS 1 send on the
individual vocal channels to the desiredlevel.
ANSWER: Yes! Use the MAIN preamp output jack to
feed a full range main signal to your sub-woofer or
active crossoverand power-amp.
ANSWER: Yes! To use both power-amps for mains, set
the POWER AMP ASSIGNMENT switches & to
the UP (MAIN) position. Touse both power-amps for
monitors, set the POWER AMPASSIGNMENT
switches (#41*) to the DOWN (MONITOR)
position.
ANSWER: YES! Takethe Line level output of the
external non-poweredmixer and connect to one of
the LINE ¼” inputs . Make sure the pad switch
is NOT pressed in. Set the individual channel tone
controlto the twelve o'clock position and bring up
the channel volume controlas needed.
ANSWER: Yes!For MAIN Master feed, connect a
shielded high-Z instrument cable fromthe Preamp
output MAIN jack tothe Line level input of the
desiredexternal power-amp.
ANSWER: No. Youcan safely use a combination of
condenser and dynamic microphonesat the same
time.

9. I have the Digital Effects Control knobs on
Channel and Monitor turned up but still do not
hear any effects throughthe monitors. Why?
I have a channel that I want in the Mains but not
in the monitors. The MonitorVolume on the
channel is all the way down but still comes
through the monitors.Where is this coming from?
ANSWER: The Main volume onthe channel is not
turned up . Because the effects send fromthe
channels is Post Main, theremust be signal present
at that channels main output.
ANSWER: It is coming fromone or both of the
Digital Effect Monitorcontrols & along with
one or both of the channel Effect controls &
being turned up. Fix the problemby turning down
Effect 1 or2 on the channel, or Effect 1
Monitor or Effect 2 Monitor on the digital
effect.
