The main chassis of the SR24•4 and SR32•4 mixing consoles is made of solid steel monocoque construction. Because the steel doesn’t flex, the console itself is quite sturdy. And at the same time, the SR Series consoles don’t weigh a ton, either.

protection from RF interfer- ence. (As you well know, many installations suffer from such problems.) Metal lockwashers make electrical contact between the jack and outer chassis, and an internal shunting capacitor is placed from each input to ground. This routes RF back through the metal chassis, where it is dissipated before it can propagate via the SR24•4 or 32•4’s circuit boards.

The SR Series consoles have built-in power sup- plies (instead of a “wall wart,” which takes up pre-

you’re sure to have plenty of power. We could go on and on, but suffice to say that people who have hauled their SR24•4s and 32•4s all over the country will attest to their durability. They’ll hold up to years of use with nary a problem.

Controls are designed to withstand serious downward impact. From a fistpounding to a heavy box dropping, the SR Series’ knobs can take it. We also use sealed controls rather than open-frame potentiometers that eventually deteriorate from airborne contamination. Switches are

There’s more. 1/4” jack sleeves are metal, not plastic. That’s part of the reason why the SR24•4 and 32•4 have such exceptional
