The HeadAmp6PRO from ART Pro Audio is a 6-channel stereo headphone amplifier designed for installed applications. The amp includes front and rear output jacks via 1/4" TRS connectors for flexible connectivity. Input is via XLR and 1/4" TRS jacks, with matching Thru jacks for bridging multiple amps. A front-panel 1/4" jack allows quick patch override of the rear inputs. The amp also include a 6-channel Aux input section, which can be used to provide the often-requested "more me" function on a headphone mix. Each output channel features individual bass and treble controls, as well as a dual-function balance control, which can pan between the left and right sides of the main signal, or vary the mix between the main and Aux inputs for that channel. Front-panel Mono select buttons on each channel allow you to switch between 4 different operating modes; Stereo, Mono Left, Mono Right, and Mono Both for versatile monitoring options. An 8-segment LED level meter provides visual feedback of the signal level on all channels and the main signal bus.
