REAR PANEL CONNECTIONS
The rear panel provides a number of jacks that can greatly enhance your Etherwave Theremin
experience. By design, these connectors have been placed away from the player, so as not to interfere
with the performance. In addition to the necessary power and audio connections, your Etherwave
Theremin also provides a number of CV (Control Voltage) jacks used for controlling other analog
synthesizers and modules.
AUDIO OUT
This is the main instrument output. Use a 1/4” instrument cable (TS) connected
here to send an audio signal to an amplifier, monitoring system, or recording
console. No signal is sent from this output when the MUTE button on the front
panel is engaged (MUTE LED indicator lit).
MUTE SWITCH
In addition to using the MUTE button on the front panel, the Mute Function can
also be turned On and O using an optional footswitch plugged into this jack.
In either case, the MUTE LED indicator will remain lit (red) while the Mute
Function is engaged.
MUTE SWITCH 1/4” (TS): Either a momentary or latching footswitch can be used.
A normally closed momentary footswitch will mute the instrument until the footswitch is
pressed and held. A normally open momentary pedal requires the footswitch be pressed
and held to mute the instrument. Some footswitches allow the user to select between
normally open and normally closed behavior.
CONTROL JACKS
In the world of analog modular synthesizers, there are two types of signals: audio signals and control
signals. Control signals use a variable voltage (Control Voltage, or CV) to change the value of a
particular parameter. Using these 3.5mm CV jacks, Etherwave Theremin can act as a controller,
interfacing directly with modular and semi-modular synthesizers. A more complete explanation of
Control Voltage and creative uses for these jacks can be found in the Controlling Moog Synthesizers
section (page 24) of this manual.
PITCH CV OUT
The Pitch Antenna can be used as a Control Voltage source. The PITCH CV OUT
value is determined using the one-volt-per-octave (1V/OCT) Control Voltage
standard. This output can be used as a CV source for other synthesizer equipment.
PITCH CV OUT (TS): –2.5V to +4.5V
NOTE: C3 (one octave below Middle C) is calibrated to produce an output of zero volts.
