The HP12E’s rear panel features dual left/right 1/4 ” (6.5mm) TRS inputs, left/right
1/4 ” TRS link outputs, left/right balanced XLR input, AC power input, and a voltage
selector switch.
5.1. Input Channel A
The left and right 1/4
” TRS inputs can accept either balanced or unbalanced sources.
Signals appearing at the A inputs are routed to the headphone outputs when an
output channel’s front-panel source selector switch is set to A. Use the left input for
mono sources; the signal will be routed equally to both the left and right sides of the
headphone outputs.
5.2. Input Channel B
The left and right 1/4
” TRS inputs can accept either balanced or unbalanced sources.
The left and right XLR signals accepted balanced line-level signals. Signals appearing
at the B inputs are routed to the headphone outputs when an output channel’s
front-panel source selector switch is set to B.
5.3 LINK Outputs
Left/right inputs A are mirrored at the left/right LINK outputs. This allows you to feed
the source signals, daisy-chain style, to additional units, for expanding the system
beyond 12 outputs.
5.4 Voltage Selector
Make sure the correct voltage for your location is is selected before using or
connecting power to the HP12E. Operating the unit at the wrong voltage setting
for your location will cause serious damage to the unit. Damage caused by such
usage is not covered under waranty.
