Mix TOP/SUB mode (A/B MIX, C/D MIX)
The Mix TOP/SUB mode allows d&b fullrange systems (passive
systems) and actively driven d&b subwoofers to be linked together
and connected to the amplifier using a single 4-wire cable.
TOP cabinets (setups) can be selected on channel A (C) and SUB
cabinets (setups) on channel B (D).
In Mix TOP/SUB mode both amplifier channels of the
corresponding pair (AMP A/B, AMP C/D) are connected to both
output connectors (AMP A and AMP B to OUT A and OUT B ...)
while the audio input for each amplifier channel can be assigned
via the input routing.
Two output connectors (A/B, C/D) are wired in parallel using the
respective pins for TOP and 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+ = Amp A (C) pos. (TOP)
1— = Amp A (C) neg.(TOP)
2+ = Amp B (D) pos. (SUB)
2— = Amp B (D) neg. (SUB)
EP5
SPEAKER OUTPUTS A/B (C/D):
1 = Amp A (C) pos. (TOP)
2 = Amp A (C) neg. (TOP)
3 = Amp B (D) pos. (SUB)
4 = Amp B (D) neg. (SUB)
