In "Dual channel mode" the D12 acts as a two channel amplifier –
stereo amplifier. The amplifier channels are connected to their
respective output connectors (AMP Ch A to OUT A and AMP Ch B to
OUT B). Each output connector is wired in parallel using the respective
pins for TOP or SUB configurations (refer to section 5.2.5.1.
Loudspeaker pin assignments and equivalents on page 19).
The "Dual channel mode" is dedicated to d&b fullrange systems (passive
systems) and actively driven d&b subwoofers. Both channels can be
configured for TOP or SUB cabinets independently.
In "Dual channel mode" the SenseDrive function is available for
applicable cabinets on channel A and B (with EP5 or NL8 connectors
only).
In "Dual channel mode" all four pins (TOP and SUB) are driven. This
could cause damage to TOPs when a SUB configuration is selected on
the respective channel.
The D12 will monitor the current through the different output pins and
will detect if a wrong cabinet type is connected. Depending on the
setting of the D12 the error message "
Top/Sub-Mismatch" will be
given out on the LCD and the respective channel will be muted. Please
refer to the D12 Software manual section under "D12 Settings menu –
Options – TSM Detection (Top/Sub-Mismatch)".

In "Mix TOP/SUB mode" Both amplifier channels are connected to both
output connectors (AMP Ch A and Ch B to OUT A and B). The output
connectors are wired in parallel using the respective pins for TOP and
SUB configurations. (refer to section 5.2.5.1. Loudspeaker pin
assignments and equivalents on page 19)
The "Mix TOP/SUB mode" is dedicated to d&b fullrange systems
(passive systems) and actively driven d&b subwoofers while TOP
cabinets (setups) are selectable on channel A and SUB cabinets (setups)
on channel B.
In "Mix TOP/SUB mode" the SenseDrive function is available for
applicable cabinets on channel B (with EP5 or NL8 connectors only).

The "2-Way Active mode" is dedicated to d&b active systems.
In "2-Way Active mode" both amplifier channels are connected to both
output connectors (AMP Ch A and B to OUT A and B) while the
loudspeaker cabinets (setups) are selectable on Channel A. All settings
of channel A and the input signal are linked to channel B and cannot be
configured individually.
In "2-Way Active mode" the SenseDrive function is available for
applicable cabinets on Channel A (with EP5 or NL8 connectors only).
