MUTE AND MONITOR
Muting and monitoring controls are conveniently 
located on the front panel, where they are easily 
accessible during performance. This arrangement 
also minimizes interference by keeping the headphone 
cable away from other cabling, or from intruding on 
the performance space.
MUTE
Pressing the MUTE button stops any audio signals from being sent from the 
AUDIO OUT jack on the rear panel. The MUTE LED indicator will remain lit 
(red) as long as the Mute Function is On. The PHONES output is unaected 
by this MUTE button, allowing the settings and tuning to be adjusted and 
checked discreetly, before or during your performance. 
PHONES/PHONES VOL
Connecting a set of headphones to the 1/4” PHONES jack allows you 
to monitor your performance. The dedicated PHONES VOL knob sets the 
listening level for the PHONES output only. Even when the MUTE LED 
indicator is lit and the Mute Function is On, the PHONES output will 
remain active, so that any parameters can be adjusted and cued up 
without broadcasting an audio signal to the audience.
CONTROLS AND FUNCTIONS
The controls on the front panel of your Etherwave Theremin are grouped together by function, 
providing intuitive operation of your theremin. This manual will deal with each group of controls, 
first collectively, and then individually.
