9.3.1. Output mode
NOTICE!
Ensure that the connected loudspeaker type corresponds to the
actual 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. Both
channels of each pair of amplifier channels can be configured for
TOP 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 (stereo
amplifier). The amplifier channels are connected to their
corresponding output connectors (AMP A to OUT A ...) while the
audio input for each amplifier channel can be assigned via the
input routing.
Each output connector is wired in parallel using the respective pins
for TOP or SUB configurations.
Pin equivalents of NL4 and EP5 connectors in relation to the output
mode are listed in the table below.

SPEAKER OUTPUTS A (B, C, D):
1+/2+ = Amp A (B, C, D) pos.

EP5 SPEAKER OUTPUTS A (B, C, D):
1/3 = Amp A (B, C, D) pos.
2/4 = Amp A (B, C, D) neg.
