The RB-HD1 is a 1U rack-mount stereo headphone amplifier for driving up to two pairs
of professional stereo headphones from a single stereo or mono input. One headphone
socket is on the front panel with one on the rear.
The main stereo input uses electronically balanced XLR-3 connectors on the rear panel,
which can be wired un-balanced. The output volume for the headphones can be
controlled either by a pot situated on the front panel or a VCA signal supplied
externally via the remote connector.
A mono input can be mixed into the main headphone feed, for example, for mixing in
talkback to the headphones. This has an input level control via a recessed adjustable
potentiometer. The mono mix input can also be controlled remotely.
A stereo/mono switch is recessed on the rear panel to prevent accidental knocking.
With mono selected, audio is sent to both left and right ear pieces. An LED power
indicator on the front panel displays the power supply connection.
