Rack-mountable 4-channel digital PA amplifier that impresses with a high power capability and high energy efficiency. It has a low weight which makes it suitable for both fixed installations and mobile applications. It features a Class-D concept with power amplifier modules from PASCAL, delivering an excellent acoustic performance, extra wide dynamic range with very low THD (<0.05%) and excellent pulse response also in the bass range. It provides two or four channels (in bridged mode) and silent operation due to temperature-controlled fans which are only activated if the temperature rises above 85°C. It also employs a lightweight design due to compact switch-mode PSU and energy-saving concept due to high efficiency. The amplifier offers 4 level controls and is protected against short circuit, over-temperature, DC voltage at the output and overload, featuring LEDs for indicating power, signal, bridge, overload (clip), overheating and protect. It provides one NEUTRIK POWERCON connector, four 3-pole XLR and four RCA connectors, four NEUTRIK SPEAKON and two NEUTRIK SPEAKON bridge connectors. Power rating at 4 Ohm: 4 x 500 W. Power rating at 8 Ohm: 4 x 280 W. Power rating with 4 Ohm bridged operation: 2 x 1000 W. Power rating with 8 Ohm bridged operation: 2 x 1000 W. Peak music power output: 2400 W. Frequency range: 20 Hz-20 kHz. S/N ratio: >119 dB, A-weighted. Dimensions: 482 x 335 x 89 mm, 2 RS. Weight: 6.6 kg.
