5.2 Use the HPA4 as Independent Power Amplifiers

Instead of using the HPA4 as the Headphone Amplifier, in many particular circumstances, it can also be conducted
as the independent power amplifiers, as for this kind of application, please turn the Balanced Control to complete
clockwise.
By setting the Balanced Control to AUX position, the Main signal will then be muted, only the signals coming from
Aux In Input can be routed to the headphone amplifiers circuit. So, now, you can apply up to four independent
stereo program sources to the mixing console, and consequently, four different and individual monitor facilities for
up to four musicians can be created.

5.3 The HPA4 in Studio Application

Generally, the Aux In Inputs are used to feed a further input signal, which can be mixed with the Main/Direct In
signal via Balanced Control, so that, well understood this function, you can get the wonderwork in the studio field.
Normal practice, if you want to record a vocal track which is intended to ride on an already existing background
musical tracks, take it easy, just use the Main Input to feed the musical background signals, and input the Vocal
signal through Aux In.
