amplifiers. As an external controller for other amps it's recommended to use

this preset. Always be aware to have the correct preset loaded on your
system amplifier before connecting the loudspeaker. Ensure that the internal
connections in the amplifier rack are identical to shown on Fig 2.

*NOTE:
LJ
For lower SPL requirements it is possible to connect 2x B15A in parallel to one amp’s channel (2 Ohm operation)
For standalone use:
for first amplifier, first channel use OUT2 on APL4. B15 ACTIVE is driven from PIN2.
For combination with top
TW AUDIO presets are designed that first channel drives LF loudspeaker/ drivers while second amplfier channel M/HF
source. For this combination always use OUT? for first amplifier and OUT4 for second amplifier.
