[NAMM] Crown 135MA & 160MA

Capable of providing both eight-ohm and constant-voltage outputs (70V and 100V), the 135MA and 160MA are configurable for a variety of uses, including paging, background music, music-on-hold, security use, and safety/evacuation announcements.

Each housed in a half-rack-space chassis, the 135MA is equipped with three inputs and a 35W amplifier output, while the 160MA provides four inputs and a 60W amplifier output. Both models provide priority muting, which can be voice-activated or triggered via an external switch, and are compatible with microphones requiring phantom power.

The front panel of each model comprises a rotary input volume knob and green signal/clip LED for every channel, rotary output volume knob with green (signal) and red (clip) LEDs, recessed pots for bass and treble adjustment, and a power switch with accompanying blue LED.

The back panel includes a balanced Phoenix-type mic/line input with threshold control, several line-level RCA input jack pairs (two for 135MA, three for 160MA), a telephone/MOH output with level control, a preamp output, screw-terminal speaker outputs, and a detachable IEC power cord. A DIP switch panel is also provided.

Convection cooled, the new mixer-amplifiers also includes current limiting, over-temperature thermal cutout, DC-fault load protection and protection against turn-on/turn-off “thumps.”

Shipping in February, the 135MA features a $199 MSRP ($159 MAP) with the 160MA set at $325 ($269).
