potentiometers that eventually deteriorate from airborne contamination. The mixer has a steel chassis, rugged double-sided, through-hole-plated fiberglass circuit boards, built-in power supply (instead of a “wall wart”), BNC lamp power connector— even parallel -wired dual faders for two times redundancy.

The CR-1604’s inputs and outputs are protected against power surges, static discharges 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 between jack and outer chassis. Internally, a shunting capacitor is placed across the inputs, routing RF back through the metal chassis where it is dissipated before it can

propagate via CR-1604 circuit boards. You can literally operate a 1604 under a transmitter tower without RF interference*! No Mackie “clone” can make that claim.

SOUNDS SO GOOD,IT’S USED TO MIXCOMPACT DISCS

In terms of specs and features, it’s quite understandable 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.
