The B-HPA is a two input mono/stereo headphone amplifier in a compact aluminium beltpack enclosure. Inputs may routed to either earpiece so the unit may be configured with stereo or dual mono inputs. Programming the B-HPA is simple using the OLED display which also shows line input levels during normal operation.

The following features are programmable:

• Input routing stereo/mono

• Channel1/channel2 headphone limiting low/medium/high

Power requirements are a PP3 size 9V battery (alkaline recommended) or a 9-16 volt external DC supply.
