WA-4X3 - 4 channels power amplifier, 4 x 200 W RMS on 8 ohm, 2 x 600 W bridged stereo

Amplificatore finale a 4 canali da 4 x 300 WRMS su 4 ohm e 4 x 200 WRMS su 8 ohm. Possibilità di funzionamento a ponte, con erogazione di 2 x 600 WRMS su 8 ohm. Gli stadi di amplificazione sono in Classe-AB, proprio come i finali per uso Hi-Fi. Potente trasformatore toroidale a basso flusso disperso. Regolazione di livello e controlli di tono bass / treble indipendenti per ogni canale, LED per presenza di segnale, clipping, intervento protezioni, funzionamento a ponte. Grande versatilità di funzionamento in configurazioni 2x2, 2+1 o 4x1. Possibilità di funzionamento anche in Bus Mode: in questa modalità, il segnale inviato all'ingresso Bus viene amplificato da tutti e 4 i canali d'uscita. Connettori d'ingresso XLR e connettori di uscita a vite per spine diffusori a banana.    - - - - - - - - - - 4-channel final amplifier with 4 x 300 WRMS into 4 ohm and 4 x 200 WRMS into 8 ohm. Possibility of bridge operation, with delivery of 2 x 600 WRMS into 8 ohm. The amplification stages are Class-AB, just like the power amplifiers for Hi-Fi use. Powerful low leakage flux toroidal transformer. Level adjustment and independent bass / treble tone controls for each channel, LEDs for signal presence, clipping, protection, bridge operation. Great versatility of operation in 2x2, 2+1 or 4x1 configurations. Possibility of operation also in Bus Mode: in this mode, the signal sent to the Bus input is amplified by all 4 output channels. XLR input connectors and screw output connectors for banana speaker plugs. - - - - - - - - - -
