INTRODUCTION
The HeadAmp6 is a full-featured six -channel stereo headphone amplifier that includes six auxiliary inputs to
allow separate mixes on each headphone channel. 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.
Each output channel includes one front and two rear panel stereo 1/4-inch TRS headphone jacks for ease of
installation and quick patching capability. Mono, Mute L, and Mute R 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. Independent output level controls on each channel personalize monitoring levels.
Input options include XLR and 1/4-inch TRS balanced inputs with matching “Thru” jacks for bridging multiple
units. An additional front panel stereo 1/4-inch TRS Direct In jack for quick patch override of the rear panel
inputs is included for quick insertion of any stereo source. Master Volume control sets the main signal bus
level. Eight-segment precision LED level metering on the main bus and four-segment indicators on each output
channel provide visual feedback of the signal level at all key points.
INSTALLATION
The HeadAmp6 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 better performance and greater 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 HeadAmp6 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.
