9.3.1. Output modeNOTICE!Ensure that the connected loudspeaker type corresponds to theactual output configuration of the D80.Dual Channel mode (A/B, C/D)The Dual Channel mode is dedicated to d&b fullrange systems(passive systems) and actively driven d&b subwoofers. Bothchannels of each pair of amplifier channels can be configured forTOP or SUB cabinets independently.In Dual Channel mode each pair of amplifier output channels(AMP A/B, AMP C/D) acts as a two channel amplifier (stereoamplifier). The amplifier channels are connected to theircorresponding output connectors (AMP A to OUT A ...) while theaudio input for each amplifier channel can be assigned via theinput routing.Each output connector is wired in parallel using the respective pinsfor TOP or SUB configurations.Pin equivalents of NL4 and EP5 connectors in relation to the outputmode are listed in the table below.NL4 SPEAKER OUTPUTS A (B, C, D):1+/2+ = Amp A (B, C, D) pos.1—/ 2— = Amp A (B, C, D) neg.EP5 SPEAKER OUTPUTS A (B, C, D):1/3 = Amp A (B, C, D) pos.2/4 = Amp A (B, C, D) neg.5 = n.c.2 x Dual Channel moded&b D80 Manual 1.8 en 37
