CROWN 135MA
Three Input, 35W Mixer-Amplifier มิกเซอร์แอมป์ 3In/1Out 35W
Crown’s 135MA and 160MA are high value mixer-amplifiers for commercial audio. They provide 8-ohm and constant-voltage outputs (70V and 100V). Typical uses are paging, background music, and music-on-hold. The 135MA provides 3 inputs (each with a volume control) and a 35W amplifier output. The 160MA provides 4 inputs (each with a volume control) and a 60W amplifier output. Other features include priority muting, voice activated muting, phantom power, and bass and treble controls.
