ARCHITECT’S & ENGINEER’S

SPECIFICATION

The mixer amplifier shall incorporate a 150 W monophonic amplifier, a 5-band graphic equalizer and a monophonic mixer with 6 microphone/line-input chan- nels. Microphone inputs shall be on XLR-type connec- tors and line inputs shall be on balanced 1/4″ Tip-Ring- Sleeve phone connectors. An independent line-level CD/tape input (routed to channel 6) shall be on phono connectors. Each channel shall have an aux/reverb send, 2-band equalization and a level control.

The mixer shall provide an effects output on a 1/4″ phone connector, as well as a preamp out and power amp in for submix applications on 1/4″ phone connec- tors. An effects return shall be provided on a 1/4′′ phone connector, and it shall have an independent level con- trol. Phantom Power of +48 V shall be provided for operation of condenser microphones. The amplifier shall be passively cooled. Amplifier output shall be provided on two 1/4″ phone connectors. Indicators shall be pro- vided for peak level (3 dB before clipping), power and amplifier protection. The unit shall be of a rack-mount type.

The amplifier shall deliver maximum power equal to or greater than 150 W into 4 ohms, signal-to-noise equal to or greater than 95 dB, THD less than 0.1% and frequency response of ±3 dB from 20 Hz to 50 kHz. The mixer shall have residual noise of 70 dBu, signal-to-noise equal to or greater than 70 dB and THD less than 0.03%. Total power consumed at 1/8 audio power shall be 134 W (115 Vac). Dimensions shall be 19″ (480 mm) wide, 9″ (230 mm) deep and 3.5″ (88 mm; 2 rack spaces) high. Weight shall be 17.6 lb. (8 kg). The mixer amplifier shall carry a three-year warranty.

The mixer amplifier shall be a SAMSON S62.
