Mackie CR-1604 Product Information page 2

potentiometers that event-
ually deteriorate from
airborne contamination. The
mixer has a steel chassis,
rugged double-sided,
through-hole-plated fiber-
glass circuit boards, built-in
power supply (instead of a
"wall wart"), BNC lamp
power connector— even par-
allel-wired dual faders for
two times redundancy.
The CR-1604's inputs and
outputs are protected against
power surges, static dis-
charges and even impedance
mismatches.

And the mixer also has
exceptional protection from
RF interference. Other
compact mixers use plastic
washers to secure 1/4" jacks
to the chassis. Grounding is
done internally to a circuit
board trace. This means
that RF can enter the mixer
and propagate throughout
the circuitry. The CR-1604
uses metal lockwashers to
make electrical contact be-
tween jack and outer
chassis. Internally, a shunt-
ing capacitor is placed
across the inputs, routing
RF back through the metal
chassis where it is dissi-
pated before it can

SOUNDS SO GOOD,
IT'S USED TO MIX
COMPACT DISCS
In terms of specs and
features, it's quite under-
standable why the CR-1604
has redefined small mixers. It
put an end to the classic
trade-off of "low noise OR
high headroom, but not
both." In fact, numerous
*A Radio World magazine reviewer
did just that. See the March 25th,
1992 issue for the full story.
