Quattrocanali4804/DSP+D

Quattrocanali 4804 is a 4 channels class D power amplifier

Class D amplifier

4 channels (bridged)

4 x 1200 W, 4Ω



Quattrocanali 4804 is a 4 channels class D power amplifier usuable with all APG speakers ranges depending on the desired application.

The 4 channels can work with different loads above 2 Ohm or in 100V line. Mixed configuration can be made. When important power is needed to drive subwoofer for exemple, the amplifier can work in bridged mode. Dedicated to fixed installation, Quattrocanali has an important efficiency. The electric consumption and the heat dissipation is weak compared to the output power. The protection against over/under voltage, clipped signals, VHF emissions, and short circuits make the amplifier reliable. Quattrocanali 4804 is equipped with GPI connector for external VCA volum control and alarm GPO connectors. An ethernet port makes the control by external device possible.

Quattrocanali 4804 exists with an integrated DSP processor and Dante Input under the reference Quattrocanali 4804 DSP+D. Quattrocanali 4804 DSP+D will offer a 4 x 4 matrix or all analogue and digital inputs. Integrated in the DSP will offer filters per channel offering aised-cosine, customFIR, parametric IIR, peaking, hi/lo-shelving, all-pass,band-pass, band-stop, hi/lo-pass filters and a crossover linear phase (FIR), Butterworth, Linkwitz-Riley, Bessel: 6dB/oct to 48 dB/oct(IIR). For time alignment the DSP in the amplifier will offer Delay 2s (input) + 100ms (output). The limiters in the DSP will contain TruePower™, RMS voltage, RMS current and Peak limiters. Active DampingControl™ and Live Impedance™ measurement will be part of the DSP.
