Ashly 8-Channel 2000W Network-Enabled Power Amplifier with OPDAC8 and OPDante Cards (Low-Z)

Description

The 8-Channel 2000W Network-Enabled Power Amplifier from Ashly delivers a minimum power of 150W RMS per channel into 8 ohm loads and 250W RMS per channel into 4 ohm loads with all channels operating. The amplifier features OPDAC8 digital to analog converter with selectable high-pass filter and OPDante network audio interface cards; and is designed around an energy efficient Class-D platform with a switching power supply. When switched into bridged-mono mode, channels 1+2, 3+4, 5+6, or 7+8 of the amplifier delivers over 500W RMS into an 8 ohm load.

The power amplifier includes Euroblock input connectors, Euroblock output connectors, and balanced analog inputs. Besides remote standby for power up, DC remote level control, and contact closure preset recall, the amplifier also features Ethernet control & monitoring of power functions, level, mute, polarity, temperature, current, and amplifier fault conditions. The front panel indicates power status, standby, protect, power switch On/Off, signal level, bridge, temperature & current levels, and Ethernet communication. The amplifier mounts in a standard 19” rack using two spaces (3.5” high).
