The Ashly nXp400 is a 4-channel multi-mode network power amplifier that includes Protea DSP software and Dante digital interface. It features selectable voltage gain at 26, 32, or 38 dB, or 1.4 V. The damping factor is >250 (8 Ohms load <1 kHz). It has an input high pass filter of 80 Hz 2nd order. Distortion is SMPTE (Typical): <0.5% THD-N (Typical): <0..5% (8 Ohms, 10 dB below rated power, 20 Hz to 20 kHz). Channel separation is -75 dB (dB from full output, 1 kHz). Signal-to-noise ratio is >105 dB (20 Hz to 20 kHz, un-weighted). Frequency response is 20 Hz to 20 kHz, ±0.05 dB. Input impedance is 10 kOhms. Balanced input includes Euroblock 3.5 mm, 1/4" TRS and XLR combo jack. Maximum input level is +21 dBu. Speaker output is Neutrik speakON.
