ARCHITECT'S and ENGINEER'S SPECIFICATION

The power amplifier shall be a dual channel model of solid state design employing true complementary symmetry output circuitry and capable of operating from 120/ 240 Vac, 50/ 60 Hz line. The amplifier shall contain sensing circuitry to provide protection against over-temperature, shorted outputs, excessive output voltage, radio frequency interference, and excessive output phase shift. The load shall be similarly protected against subsonic signals, startup/shutdown transients, low ac line voltage, and DC faults.
Rear mounted panel controls shall include a two position mode switch for selecting between the dual monophonic mode or the bridged monophonic mode. Input connections for each channel shall include a powered octal accessory socket for the use with optional plug in accessory modules, a 3-pin XLR connector, and a 1/4 inch phone connector. Output terminals shall be a barrier strip connector.
Front panel indicators shall include an illuminated power on/off indicator, individually illuminated clipping ("CLIP") indicators, and an illuminated protection circuit activation ("PROTECT") indicator. The front panel controls shall include individual input level controls and a power on/off switch.
The power amplifier shall meet the following performance criteria: Maximum input voltage: 7.775 Vrms. Input sensitivity for rated output power into 4 ohms: 0.775 Vrms. Rated output power: 100 watts per channel into 4 ohms from 20 Hz to 20 kHz at less than 0.1% THD; 75 watts per channel into 8 ohms from 20 Hz to 20 kHz at less than 0.1% THD; and 200 watts into 8 ohm bridge load from 20 Hz to 20 kHz at less than 0.1% THD. Voltage gain in dual mode shall be 28 dB. Hum and noise at least 100 dB (A-Weighting) below rated output power. Frequency response: 20 Hz to 20 kHz, ±1 dB at any power up to rated output power. Damping factor: greater than 100 at 1 kHz in dual mode 'with 8 ohm load. Intermodulation distortion (SMPTE 4:1): less than 0.1%. Crosstalk; less than 55 dB below rated output power. Operating temperature range: up to 50 °C (122 °F) ambient. Dimensions: 1.75 in H x 19 in W x 12.8 in D (4.44 cm H x 48.26 cm W x 32.51 cm D). Net weight: 18 lbs (8.16 kg). Color: Black. Enclosure: rack mounted chassis; 16 GA steel with .1875 inch thick 5052 aluminum alloy front panel.
The power amplifier shall be the ALTEC LANSING Model 9441A.
