ART Pro Audio HeadAmp6 - 6 Ch. Headphone Amp - Manual (Page 6)

Balance Control
This control provides one of two functions depending on whether there is a plug inserted into the stereo AUX
IN for a particular channel.
With no plug inserted into the AUX IN jack, the control will vary the Left / Right balance of the main signal bus
feed to the channel.
With a plug inserted, the control changes function to vary the mix between the stereo signals coming from the
main signal bus and the stereo signals coming from the AUX IN for that respective channel. By feeding a return
signal for only the vocal microphone of a particular musician into the AUX IN you can use the BALANCE
control as a ‘More Me” control by varying the mix between the microphone signal alone, and the main signal
bus audio. This effect is heard only in the individual headphones of the specific channel.
Level Control
This control varies the audio output level feeding the front and rear panel 1/4-inch stereo output jacks for
each respective channel. The four-segment LED level meter, located above the switches on each channel,
displays the audio level for each channel output.
Power Switch
This rocker switch turns the AC power On and Off. A small LED indicator in the rocker button illuminates to
indicate that the power is on.

Balanced Main Inputs
These XLR and 1/4-inch TRS jacks are active balanced and are used for line level signals. The gain
sensitivity is identical for both the XLR and 1/4-inch TRS jacks. Signals applied to these jacks feed the main
signal buss. (NOTE: the front panel DIRECT IN jack overrides these inputs when it is used.)
Balanced Main Thru
These XLR and 1/4-inch TRS jacks are hardwired in parallel with the corresponding BALANCED MAIN
INPUT jacks. The BALANCED MAIN THRU jacks are useful for daisy chaining multiple HeadAmp6 units
together.
