ART Headamp 6 Pro
The ART HeadAmp 6 Pro is a six-channel stereo headphone amplifier that I have to my Behringer X32 digital mixer. This headphone amplifier succeeds the Behringer HA4700 that I used previously.
The ART HeadAmp 6 Pro 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. I have connected the Aux 5 and Aux 6 to my patchbay. This allows me to make submixes on my X32 (or in Cubase) and to send these only to specific headphones, which is convenient during recording. These submixes are mono (one X32 channel) and go out on a single X32 output (XLR), and then (through my patchbay; mono jack) in the stereo AUX (TRS jack). As a consequence, you will hear the submix only on one side of the headphone (and for some reason also the stereo main input). However, by pressing the mono L and mono R button this problem is solved although you will have a mono headphone mix.
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.
The main outputs for each channel of the headphone amplifier are rear mounted stereo TRS jacks and are wired in parallel with the corresponding output jacks on the front panel. Front panel, rear panel, or both front and rear panel outputs can be used simultaneously to drive headphones or be used as feeds to additional headphone amplifiers in a distributed audio network.
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.
