The KLR Series delivers performance with the best signal/noise ratios of any amp in it's category. The power amplifier shall be the Ashly KLR-4000

The two-channel power amplifier shall incorporate the latest amplifier technology to deliver a minimum power of 2,000 Watts per channel into 2 Ohm loads, 1,400 Watts RMS per channel into 4 Ohm loads, or 850 Watts RMS per channel into 8 Ohm loads with both channels operating. The amplifier shall have rear panel switching for parallel mono and bridging modes. When switched into bridged-mono mode, the amplifier shall deliver 4,000 Watts into a 4 Ohm load. The amplifier protection shall include output over-current, DC output, chassis temperature, and a mains circuit-breaker. Frequency response shall be 20Hz-20kHz (1W @ 8 Ohms). The Signal-to-Noise Ratio shall be greater than 109dB at rated power into 8 Ohms (unweighted). THD shall be less than 0.05% into 4 Ohms, 20Hz-20kHz and 10dB below rated power. The amplifier shall have a channel attenuator for each input on the front panel and input sensitivity select switch, a high-pass filter switch and limiter enable switch on the rear panel. The inputs shall be of balanced bridging type with XLR, ¼" TRS, and 3-pin Euroblock connectors. The outputs shall be four pin SpeakON type
connectors. LED type indicators shall be employed to show the relative power level of each channel, clip/protect and power on/off. Self contained forced air cooling (front in) shall be used with front panel mounted, removable dust filters. The power amplifier shall weigh 26.7lbs/12.1kg net and mount in a standard 19 inch rack using two spaces (3.5 inches high). The power requirement shall be 120VAC or 240VAC ±10%, 50-60Hz, factory set.
