INTRODUCTION The ART HeadAmp 6 Pro is a six-channel stereo headphone amplifier that 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.
CONTROLS and JACKS Front Panel FIGURE 1 - Master Input and Channel One Direct In Jack The 1/4-inch TRS (Tip, Ring, Sleeve) jack on the front panel provides a stereo unbalanced input which when used will override the rear panel balanced inputs. This input is useful for when you want to temporarily insert a different main input signal from what is connected to the rear inputs, or simply make an unbalanced TRS style connection to another headphone output source.
Bass Control This control can be used to boost or cut the low frequencies in each respective channel. The bass response is flat when the control is set to the 12 o’clock position. Treble Control This control can be used to boost or cut the high frequencies in each respective channel. The treble response is flat when the control is set to the 12 o’clock position.
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. (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 HeadAmp 6 Pro units together.
HEADAMP 6 PRO OPERATION 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.
