CROWN 160MA Commercial AudioThe Crown® 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. Features• 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• Ideal for paging, background music, and music-on-hold• Balanced Phoenix-type mic/line input, telephone output, dual RCA stereo music inputs, screw-terminal speaker outputs• Priority muting by VOX or external switch• Bass and Treble controls on master output Specifications• Frequency Response (at 1 watt from line out):◦ 50 Hz to 20 kHz ± 1 dB.◦ 19 Hz to 34 kHz +0, –3 dB.• Signal to Noise Ratio (ref. to rated power, master volume at minimum):• THD + N: < 0.5% at rated power at 1 kHz. < 0.1% at 5W at 1 kHz.• Input Sensitivity (for full output at maximum gain):◦ Input 1: Mic 3mV, Line 800mV.◦ Input 2: 400mV.◦ Input 3: 400mV.◦ Input 4 (160MA only): 400mV.• Input Impedance (nominal):• Crosstalk: –82 dB at 1kHz (Ch. 1 line input 0.8V, Ch. 1 volume at minimum, other channel volumes at maximum).• Line Output Level (nominal): 1V into 10 kilohms.• Phantom Power: 15 VDC• AC Line Voltages Available: Universal Power Supply.
