BS 286 DUAL CHANNEL SEPARATE POWER SUPPLY

The BS 286 is a 2-channel switch mode power supply with AUX input for program signals.
It is housed in a 19"/1U steel case and is designed to be able to safely drive 20 beltpacks BS 15,
when each is driven to full volume. It is fully protected such that if there is a short circuit,
miswiring on any part of the system, or a dangerous thermal condition, it will shut down. Once
the fault condition has been removed, the power supply will automatically reset and full power
will be restored. The BS 286 can be connected to mains power 100V - 240V AC (50/60Hz)

Aux. Program Input

A XLR-3 connector on the rear panel allows access to
the intercom lines for external audio signals.
The input is electronically balanced and switchable
between line or 30V phantom powered mic level
inputs. On the front panel AUX signal volume controls
are provided, one for each channel.
