DA-1250D-EB

The dual-channel power amplifier shall use digital class-D circuit topology and shall be configurable to allow two channel operation. Power output in two-channel mode with all channels driven shall be: 1250W per channel into 4 ohms and 700W per channel into 8 ohms. The channels shall be bridgeable to produce 2500 W into 8 ohms. Total harmonic distortion (THD) shall be less than 0.15% (1kHz). The frequency response shall be 20 to 20,000 Hz (+/-3dB). The signal to noise ratio shall be over 100 dB (A-weighted). The input impedance shall be 20k ohms for each input into an balanced input circuit and 10k ohms for unbalanced input circuit. A rear panel switch shall allow selection of bridged, parallel or stereo operation. A rear panel switch shall allow selection of 0.775V, 1V or 32dB sensitivity. Each input shall feature an XLR-F connector and an XLR-M connector to  link the source. Rear panel output connector shall be NL4 Speakon. The front panel attenuators shall be taper potentiometer. The front panel shall have two LED indicators with 7 LEDs each to indicate the following conditions: Power, Signal, -20 dB, -10dB, -5dB, Clip and protection circuit activation. The front panel shall have an I/O switch. The front panel shall also have two removable air filters that may be removed for cleaning without removing the amplifier from the rack. The amplifier shall be forced-air fan cooled with the air intake at the front and exhaust at the rear. 

Power consumption shall be 1100 W ( 2/3 rated, 8 ohms per channel).The amplifier shall use only two standard rack-space or 89 mm and its dimensions shall be 483 (W) x 89 (H) x 305 (D) mm. Front panel and case finish shall be black plated steel sheet. Weight shall be 6.4 kg. 

The amplifier shall be a TOA model DA-1250D.
