Crown G160MA 4 Input x 60W Mixer Amplifier, 70V/100V

A high-value mixer-amplifier for commercial audio applications.

The 160MA from Crown is a 4-input, 60W mixer-amplifier for commercial audio applications. The 160MA provides 8 Ω and constant-voltage outputs (70 V and 100 V), and is ideal for paging, background music, and music-on-hold systems. Its four inputs (each with volume control) and 60W output rating are enhanced by pro features like priority muting, voice-activated muting, phantom power, and bass/treble controls.
