ART Pro Audio HPFX - Headphone Mixer/Amplifier - Manual (Page 7)

HPFX REAR PANEL CONNECTIONS
Despite the HPFX’s sophistication, it is easy to interface the unit with a wide variety of equipment.
With the exception of the front panel headphone outputs, all inputs and outputs, are located on the
rear panel. Standard ¼” and XLR inputs and outputs make patching simple.
POWER JACK INPUT
An external 9 Volt AC adapter powers the HPFX. Plug the adapter into the PWR jack and then
into a power outlet. Only use the adapter that came with the HPFX. If the adapter ever
becomes damaged, immediately discontinue use.
EFFECTS OUTPUT
The Effects Output Jack brings out the combined microphone and effects signals on a ¼”
T.R.S. (Tip, Ring, Sleeve) jack. Tip is the left channel and Ring is the right. This allows you to
use the HPFX as a digital effects unit, independent of the headphone and stereo mix signals.
STEREO MIX LEVEL PAD
This switch, when in the in position (Pad), acts to attenuate the signals at the Stereo Mix Input
jacks by 20dB. This allows you to run a “hot” monitor signal (from another headphone amp or
small monitor amp in a studio) back into the unit, without worrying about overdriving the HPFX
circuitry. In the “Norm” position the Stereo Mix Inputs will handle any line level signals up to
+20dBu.
