2-channel Power Amplifier, 3000W Power

2-channel power amplifier draws 1800W or less at 1/8 rated power into 2 ohm loads. The power amplifier shall be capable of operation from a 120V, 60Hz line. Dual power supply transformers are employed. Power output with both channels driven shall be a minimum of 2750W per channel with a 2 ohm load, 3000W per channel with a 4 ohm load, 1800W with an 8 ohm load, 6000 W mono bridged into an 8 ohm load, and 5500 W mono bridged into a 4 ohm load. Burst peak output with both channels driven shall be a minimum of 4100W per channel with a 2 ohm load. Total harmonic distortion (THD+N) shall be less than 0.2% at 10Hz-20kHz, half power. Intermodulation distortion (IMD) shall be less than 0.25% using the SMPTE standard of 60 Hz and 7kHz in a 4:1 ratio respectively at half power. Frequency response shall be from 20Hz to 20kHz (Max +0.5dB, TYP +0 dB, Min -0.5 dB) at 8 ohms, Po=1W. Residual noise at 20Hz-20kHz shall be less than -65dBu. Input shall be electronically balanced, with a minimum impedance of 20k ohm balanced and 10k ohm unbalanced. The voltage gain shall be configurable in 0.1dB steps between 19.8dB to 43.8dB. Maximum input voltage shall be 24dBu. The unweighted signal to noise ratio over the range of 20Hz-20kHz shall exceed 108dB, referenced to full output. Built-in protection circuitry shall monitor voltage and current levels to minimize potential damage from overloads, and disable output during shorts, DC offset, or excessive operating temperatures exceeding 100° C. The relay shall also delay amplifier connection to the load during turn-on for nine seconds. In-rush current limiting shall minimize turn-on current surges when multiple units are powered-up remotely to prevent AC breaker overload. The amplifier shall employ forced-air cooling with dual temperature-controlled fans, variable in speed for minimum acoustic noise. Air flow shall be from front to rear. The front panel shall have a recessed AC power switch, two MUTE buttons, four Function buttons, a HOME button, an ENTER button, two encoders and LED indicators. The LED indicators shall indicate IDENTIFY, NETWORK, PROTECTION, BRIDGE, PARALLEL, POWER and STANDBY conditions. Front panel indicators shall include an LCD screen to control the amplifier's setup and operation. Rear panel input connectors shall be a 3-pin XLR connector for each channel and available input connectors via the Mini-YGDAI card. The XLR input shall be wired with pin 2 hot. Rear panel output connectors shall be 5-way binding posts, SPEAKON connectors, XLR Thru outputs and available connectors via the Mini-YGDAI card.
