(A) MAIN IN
These terminals allow a connected external (A) amplifier to play through to
the
SPEAKERS OUT 1 & 2
output terminals in the absence of a trigger to the
internal (B) amp of the BB50-S. This allows A/B amplifier switching based on
conditional triggering of the BB50-S.
(B) SPEAKERS IN
For use of these terminals, please refer to
page 7
.
OPERATING MULTIPLE SPEAKERS
Multiple pairs of speakers can be connected directly to the amplifier's
SPEAKERS OUT 1 & 2
outputs
(refer to Diagram 13)
as long as the total
impedance presented to the amplifier does not drop below 4ohms. If excessive
demands are placed on the amplifier, the protection circuitry may be engaged,
temporarily shutting it down.
When speakers are connected directly to the amplifier, they will all play at
the same time. If you wish to control speaker pairs independently of each
other, we recommend that you use one of SpeakerCraft's multi-room speaker
selectors. Depending on the model, up to eight pairs of speakers can be
turned on or off independently of each other, while providing protection for
your amplifier at the same time. Your SpeakerCraft dealer can provide you
with details on the selectors available.
POWER
3-PRONG REMOVABLE POWER PLUG
Plug the female end of the AC cord supplied with the BB50-S into the IEC-Type
receptacle on the rear panel of the amplifier.
(See Diagram 2)
Insert the plug
directly into a 120V AC / 60Hz wall outlet.
CAUTION:
Do not plug the amplifier into a preamplifier’s or receiver’s
switched or unswitched outlet. If you wish to have the amplifier turn on
once a preamplifier or a receiver is activated, use the “AUDIO ON” trigger
mode selection. (Refer to Diagram 9)
120V AC OUTLET
This is an AC current sensing AC Outlet. It is NOT turned On or Off by the
front panel POWER switch. Use this outlet to sense the AC current of an AC
powered appliance or device for triggering purposes.
Refer to Diagrams 9
and 11 and related text for details.
