[. . . ] However, for greater reliability we recommend that you not place the HPFX on top of power amps, tube equipment, or other sources of heat. AC POWER HOOKUP The HPFX has an external power supply designed to operate at 110 VAC @ 50 to 60 Hz. Units manufactured for use outside the United States of America have been modified to comply with the required electrical specifications. If the adapter becomes lost or damaged, contact ART Customer Service for replacement. AUDIO CONNECTIONS Audio connections to and from the HPFX are balanced XLR (Pin 2 = Hot (+), Pin 3 = Cold (-), Pin 1 = Ground) and unbalanced ¼" (Tip = Hot (+), Sleeve = Ground). We recommend using only high-quality shielded cables equipped with high-quality connectors. SAFETY PRECAUTIONS Warning: To avoid the risk of shock or fire, do not expose this unit to moisture. Do not remove the metal covers; there are no userserviceable parts inside. Only use the power adapter that came with this unit or one obtained from ART's Customer Service Department. -3- 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. Connect your microphones to the XLR Mic INPUTS on the rear, and connect the THRU outputs to your preamp or mixers mic inputs. Next connect your cue track or stereo signal that you want to monitor, into the STEREO MIX INPUTs. Plug your headphones into the front jack and you are done with the basic setup. The following diagram details connections to the unit and shows the audio signal flow within the HPFX. This is also printed on the top of the HPFX, for quick reference. f f -4- 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. MICROPHONE EFFECTS BLEND The Effects Blend controls adjust the amount of each microphone's signal that is sent to the digital effects section, similar to the effects send section of a mixer. DIGITAL EFFECTS SELECT This encoder lets you select any one of 16 digital effects, to be applied to the microphones signal and mixed into the headphone outputs and the rear panel effects output jack. The effects available include: 4- discrete delay (slapback), 4- echo, 5- reverberation, and 3- special effects (flangers, choruses, and discrete). They are nominally tailored to vocal use (sweetening an thickening), but they can be adjusted over a wide range, by judicious use of the Effects Blend and Parameter Adjust controls. -5- 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. In the center position, the nominal parameter settings work well for vocal ambience treatment and for sweetening the sound, to avoid fatigue when using headphones for an extended period. As you increase this control, the effects become more pronounced, up to the point where you get very long delays and reverberation decays when desired. This allows the HPFX to be used in a pinch as a stand alone digital effects unit. HEADPHONE OUTPUT LEVELS (A, B, C, & D) The Headphone Output controls let you independently vary the gain of each headphone output with up to 18dB of additional gain over the line level signal. This gives you a total of up to 74dB of gain for the microphone inputs. Each control has its own amplifier. HEADPHONE OUTPUT JACKS (A, B, C, & D) The Headphone Output jacks are ¼" T. R. S. [. . . ] Check to make sure the unit has power supplied, all cables are connected correctly, and the cables themselves are in working condition. 2) If you find the unit to be at fault, write down a complete description of the problem, including how and when the problem occurs. Please write down a description of your complete setup before calling Customer Service. 5) Include with your unit: a return shipping address (we cannot ship to a P. O. [. . . ]
