Head Amp Control
4. Click the Head Amp Tab.
It can take a few seconds for the channel name in the Ch Selection field to appear.
The head amplifier parameters can be controlled from this display. The current parameter settings will be shown on the display
when “ch 1-8” or “ch 9-16” is selected from the Ch Selection filed.
• If you later decide to switch back to controlling the head amplifiers from a digital mixer, we recommend
executing the Quick Setup function again, although the same result can be achieved by un-checking
the [Head Amp PC Remote Control] checkbox and setting the Serial Communication Mode to [Unicast]
(via an MY16-ES64).
• The AVS-ESMonitor application cannot be used while a ring network is in operation. In order to use the
AVS-ESMonitor application to control the head amplifiers it is necessary to either switch to a daisy
chain configuration or add an EtherSound device with a third-port to the system.
• The on-screen head amplifier controls can be operated both by click-and-drag and via the mouse scroll
wheel.
• Sound output may be briefly interrupted when adjusting gain, but this is normal. Since the gain is being
internally adjusted in 6-dB steps, output is briefly muted to prevent noise.
• The following parameters are not supported and cannot be edited even if shown on the display:
Device Mode/Name, Word Clock Source, Gain trim, Panel Lock, LED Brightness
