S 18 S 28
UB AND UB
When driven by DYNACORD SL,
LX or Power-H series amplifiers, a
single four-pole cable connected
to Channel A is all that is needed
to drive both woofers. (The output
signal from Channel B is also pre-
sent on pins 2+ / 2- of Channel A ).
The SUB 28 is switchable between
1 x 4 Ω and 2 x 8 Ω operation, in
which case the signal for Subwoo-
fer A is on pins 1+ / 1-, and that for
Subwoofer B on pins 2+ / 2-, of the
Speakon connectors.
