5.3 The HPA6 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.

5.4 The HPA6 in Mono / Stereo Application
The HPA6 6-Channel Headphone Amplifier can be switched between the Mono and Stereo operational mode via
Mode Switch control. Press the Mode Switch for Mono application, the Mono LED (8) lights up. In Mono application,
the input two signals are combined together and the resulting mono signal routes to both the Left and Right Head-
phone Out Outputs.
