ART Pro Audio HPFX - Headphone Mixer/Amplifier - Manual (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. 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. Only use the adapter that came with the HPFX. 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. Refer all
servicing to qualified personnel. Do not remove the metal covers; there are no user-
serviceable parts inside. Only use the power adapter that came with this unit or one obtained
from ART’s Customer Service Department.
