H. D+N / **1Khz @ <0. 1% T. H. D+N FEATURE OVERVIEW: · Toroidal power transformer · Dual, variable speed fans on CC 2800 and CC 4000, single fan on model CC 1800 · Balanced XLR inputs · Speakon® and 5-way binding post speaker outputs · Mode selector switch for stereo, parallel and bridged-mono operation · Input sensitivity selection · Recessed, stepped attenuators · Front panel circuit-breaker switch · Five year warranty* TOURCLASS/PROTECTION CIRCUITS ACLTM (Active Clip Limiting) prevents speaker damage by providing gentle gain reduction when the signal approaches the clipping threshold. IGM (Instantaneous Gain Modulation) monitors speaker loads to detect conditions that may overstress output devices. [. . . ] Each channel will delver a minimum of (450 / 595 / 800) watts at 8 ohms, (700 / 965 / 1, 350) watts at 4 ohms, (1, 850 / 2, 800 / 4, 000) watts at 2 ohms, 20 Hz ­ 20 kHz. In Bridged mono mode, it will deliver a minimum of (1, 850 / 2, 800 / 4, 000 W) at 4 ohms, 20Hz ­ 20 kHz. It shall weigh (32. 6 / 39. 8 / 43. 3) lbs. The amplifier shall incorporate protection circuitry against output short circuits, DC voltage on outputs, thermal overload and load protection due to any form of amp failure. It will include impedance sensing circuitry, a RMS clip limiter and Autoramp signal control. The amplifier shall have a sensitivity of 1. 32 / 1. 7 / 1. 88 volts (x40) at the input, which will deliver full rated output power in any output configuration. The hum and noise level shall be greater than (-106 dB / -111 dB / -112 dB) "A" weighted. The amplifier shall have a class H output stage with a linear power supply. The frequency response shall be greater than 10 Hz ­ 35 kHz +0, -3 dB for the CC 1800 and 10 Hz - 50 kHz, +0, -3 dB for the CC 2800/4000 at full rated output power @ 4 ohms, . 1% THD. The amplifier will operate at either 120 VAC, 60 Hz (safe operating range 100-132 VAC) or at 230 VAC, 50 Hz (safe operating range 200-264), voltage selection determined at factory. Maximum current draw at 120 V shall be no greater then 15 A, both channels driven continuously into a 2 ohm load at 1/8 power. Front panel indicators shall include LED indicators for signal present, ACL (automatic clip limiting), Temp, and Active status.
