ART headamp 6 pro User Guide

 
Start with the MASTER VOLUME and LEVEL controls on all channels set fully counter-clockwise. Set the 

BASS, TREBLE, and BALANCE controls to their 12 o’clock positions. Set all mono switches to their “OUT” 
position. 

Using the appropriate balanced or unbalanced cables, (unbalanced cables will work in the rear panel inputs 

as well, but with the remote possibility of increased noise), connect the rear panel BALANCED MAIN INPUTs 
to the audio monitor signal source to be distributed to the headphones. Alternatively connect the audio signal 
source to the front panel DIRECT IN jack using a stereo TRS 1/4-inch plug. 

If connecting more than one HeadAmp 6 Pro to the same audio monitor signal source, simply daisy-chain the 

units by connecting from the BALANCED MAIN THRU connectors of the first unit to the BALANCED MAIN 
INPUT connectors of the next unit, etc. (NOTE: Daisy chaining only works with the rear panel connectors. The 
front panel DIRECT IN jack only feeds its respective HeadAmp 6 Pro unit directly.) 

Connect headphones, or leads to additional headphone amps, (like the ART HeadAmp 4) to either the front 

or rear panel HEADPHONE OUTPUT jacks (or both) using stereo 1/4-inch TRS plugs. 

If using the HeadAmp 6 Pro Auxiliary Mixer function, connect the stereo signals that are to be mixed into 

individual output channels to the appropriate rear panel STEREO AUX INPUT jacks using a stereo 1/4-inch 
TRS plug. (NOTE: For a mono signal use a TRS plug with the Tip and Ring tied together, or use one of the 
front panel MONO buttons to create a mono output to the headphones.) The AUX INPUT signal will only be 
heard in that individual channel depending on the position of the BALANCE and LEVEL controls for that 
particular channel. 

Turn on the POWER switch and with the audio monitor signal active and playing increase the MASTER 

VOLUME control to achieve a reading on the MASTER LED bar-graph level indicator which is high enough to 
light the green and yellow LEDs yet avoid lighting the RED CLIP LED on loud passages and audio peaks. 
Doing this will assure that a strong signal is available to drive each of the six individual channel amplifiers, and 
subsequently each channel amplifier will be able to run with less gain (a lower setting of the LEVEL control), 
thereby helping to optimize the signal-to-noise ratio at the outputs. 

Next set the LEVEL control on each channel to a comfortable listening level for the particular headphones 

being used. 

Set the BASS, TREBLE, and BALANCE controls to listening preference. 

NOTE: When using the Auxiliary Mixer to add a signal such as a direct vocal into an individual headphone 

channel in order to enhance that particular vocal in the mix (providing “More Me”) for the person listening to 
that headphone channel, the relative phase of the signal coming into the STEREO AUX INPUT will determine 
whether the STEREO AUX INPUT signal sums or subtracts from the main signal bus. The “More Me” effect will 
only result if the two signals add together in phase. If they are antiphase (180 degrees out of phase), the 
STEREO AUX INPUT signal will actually subtract the vocal out of the mix in the headphones for that one 
channel. Most consoles and microphone preamps will have a phase invert switch with which to set the desired 
operating mode.
