Beskrivelse

The QPA2800 follows contractor requirements for a compact, powerful and easy-to-handle 4-channel amplifier to drive multichannel low-impedance loads. Built on the proven LPA series’ technology, this amplifier basically comprises of two LPA1400 in one case. Each pair of channels can be run in stereo, bridge or parallel mono mode. A newly designed high-CMRR input circuit proves useful where source and amplifier are far apart. The LPA-based hybrid approach to amplification, using proprietary digital control of limiters and filters while retaining a purely analogue signal path, gives high dynamic reserves without compromising tonal purity. Proven linear power supply technology yields predictability at any power level. Two large 3 colour LCD displays clearly indicate the status at any time, and are legible from long distances. Sources can be connected via Combo input sockets or 3.5mm Phoenix terminals, and loads can be connected both via Speakon and via terminal strips.
