Crown 135MA
Product Description
Crown 135MA
The Crown 135MA is a high value mixer-amplifier for commercial audio. It provides 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. 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 * 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 * Three-Year, No-Fault, Fully Transferable Warranty completely protects your investment and guarantees its specifications
Specifications
* Minimum Guaranteed Power into 8 ohms or 70V/100V Output: 35W * Frequency Response (at 1 watt from line out): 50Hz to 20kHz +/-1dB; 19Hz to 34kHz +0, -3dB * Signal to Noise Ratio (ref. to rated power, master volume at minimum): Mic: > 58 dB. Line: > 60 dB. Telephone: > 60 dB. Inputs 2 or 3 (and 4 in 160MA): > 78 dB * THD+N: <0.5% at rated power at 1kHz; <0.1% at 5W at 1kHz * Input Sensitivity (for full output at maximum gain): Input 1: Mic 3mV, Line 800mV. Input 2: 400mV. Input 3: 400mV. * Input Impedance (nominal): Mic: 2.2 kilohms. Line: 10 kilohms. RCA: 10 kilohms. * Crosstalk: -82dB 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. Line voltage tolerance +15%, -20% * Operating Temperature/Humidity: 0° C to 40° C at 95% relative humidity (non-condensing). * Storage Temperature: Storage Temperature: –20° C to 85° C. * Cooling: Convection cooled. * Protection: Included protection mechanisms are current limiting, over-temperature thermal cutout, and DC-fault load protection. The unit is protected against turn-on/turn-off thumps. * Included Accessories: Power cord Non-touch cover for output connectors Phoenix-type connectors * Optional Accessories Part no. IST 600-ohm Isolation Transformer for Telephone Output or Input 1. Part no. RM1 single rack mount kit for mounting a single MA unit in a rack. Part no. RM2 double rack mount kit for mounting two MA units side-by-side in a rack. Part no. S-Cover 10-pack of security knobs. * Dimensions: Width: Half rack width (9.5 in. or 24.1 cm). Height (front panel): 3.5 in. (8.9 cm). Height (including feet): 4.1 in. (10.5 cm). Depth (front panel to back panel): 12.2 in. (31.0 cm). Depth (front of knobs to back panel): 13.9 in. (35.2 cm).
