INTRODUCTION

The ART HeadAmp 6 Pro is a six-channel stereo headphone amplifier that includes a six-channel auxiliary
input section that can be used to provide the popular “More-Me” function on each headphone mix. Each output
channel also features a dual function BALANCE control which will pan between LEFT & RIGHT sides of the
main signal bus, or vary the MIX between the main signal bus and the AUXILIARY input for that respective
channel.

Bass and treble controls are included on each output channel for fine-tuning the tone. Outputs include both
front and rear panel stereo 1/4-inch TRS jacks for ease of installation and quick patching capability. Two
MONO select buttons on each channel select between four operating modes; 1) Stereo, 2) Mono Left, 3) Mono
Right, 4) Mono Both (Left & Right) for versatile monitoring solutions.

Input options include XLR and 1/4-inch TRS balanced inputs with matching “Thru” jacks for bridging multiple
HeadAmp 6 Pro units. An additional front panel stereo 1/4-inch TRS jack for quick patch override of the rear
panel inputs is included for quick insertion of any stereo source. Eight-segment LED level indicators provide
visual feedback of the signal level on all channels as well as the main signal bus.

INSTALLATION

The HeadAmp 6 Pro may be used in a wide variety of applications and environments. Its rack-mountable
steel and aluminum enclosure is both attractive and designed for continuous professional use. Mounting
location is not critical. However, for greater performance reliability we recommend that you not place the unit
on top of power amps or other sources of extreme heat, or strong magnetic fields.

AC Power Hookup

The HeadAmp 6 Pro has an internal power supply. Only connect the unit to mains power of the type marked
on the rear panel. The power source must provide a good ground connection, and the ground pin on the mains
plug should never be defeated.

Analog Audio Connections

Audio connections to and from the HeadAmp 6 Pro are:

Rear Balanced Inputs and Outputs: [XLR] Pin 2 = Pos(+), Pin 3 = Neg (-), Pin 1 = Ground
