INTRODUCTION Thank you for purchasing an HPFX and congratulations! The HPFX solves a common problem with computer-based audio recording systems: It lets your performers locally monitor themselves through digital effects without hearing the crippling “latency” delay caused by a computer’s soundcard. The HPFX also puts the performers in control of their monitor mixes of microphone, effects, and backing tracks, while leaving the recorded signals untouched.
PAGE 3
INSTALLATION The HPFX may be used in a variety of setups including with computer-based recording systems, digital audio workstations, and ‘traditional” multitrack analog recorders. Self- contained in an all-steel, single-height 9.5” wide enclosure, the HPFX is designed for continuous professional use. Because the unit is compact and lightweight, mounting location is not critical.

QUICK SETUP: Plug the AC adapter into the back of the HPFX and then into a wall socket. Make sure that the Stereo Mix Input Level switch (on the back of the unit) is in the out (Norm) position. You may need to depress this switch later, after the other setup steps are done, if you are using a very hot monitor signal. Set the front panel controls to 12 o’clock, as a starting point. Connect your microphones to the XLR Mic INPUTS on the rear, and connect the THRU outputs to your preamp or mixers mic inputs.

HPFX FRONT PANEL CONTROLS & INDICATORS f f MICROPHONE LEVEL The Mic Level controls provide for up to 56dB of gain for each microphone’s signal, to get it up to a line level for internal processing. It is then sent to the headphone amp section and mixed with the line level stereo mix input signal. POWER LIGHT The Power LED indicator is lit whenever the HPFX is receiving sufficient and stable power from its external supply.
PAGE 6
DIGITAL EFFECTS BYPASS The digital effects bypass switch allows you to totally bypass the digital effects and get “dry” microphone signals during initial setup and when desired. This affects both the headphone outputs and the rear panel Effects Output jacks. PARAMETER ADJUST The Parameter Adjust encoder lets you adjust key parameters of each effect over a wide range.
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.
PAGE 8
STEREO MIX INPUT Connect your cue track or stereo signal that you want to monitor, into the Stereo Mix Inputs. The jacks are configured such that if you have a mono signal, to monitor, just plug into the Right input. If you have a stereo signal on a stereo jack (T.R.S.), then plug into the Left input. Plug into both inputs if you have separate left and right cables. Signals at these jacks are fed directly into the headphone amp mixer section only.
PAGE 9
OPERATION Once you have connected the HPFX to your system, familiarize yourself with its controls. Next, send audio, from your mixer or computer, to the Stereo Mix Inputs and adjust the headphone output levels for a comfortable monitor level. Then, increase the Mic Level controls until your vocal sounds balanced in the mix locally. Remember that the full dry microphone signal is still going out to your mixer or preamp for recording.
