Amplificador Crown

Features
The Crown 135MA and 160MA are high-value mixer-amplifiers for commercial audio. They provide 8Ω and constant-voltage outputs (70Vrms and 100Vrms) and can be used for paging, background music, or on-hold music.

• 3 inputs (each with a volume control), and one 35W amplifier output channel in 135MA
• 4 inputs (each with a volume control), and one 60W amplifier output channel in 160MA

Balanced Phoenix-type mic/line input, telephone output, dual RCA stereo music inputs, screwterminal speaker outputs
Priority muting by VOX or external switch
Bass and treble controls on master output
