Moog ETHERWAVE THEREMIN - Volume CV Out and Gate Out

23
REAR PANEL CONNECTIONS (Continued)
VOLUME CV OUT
The Volume Antenna can be used as a Control Voltage source. The value
of the VOLUME CV OUT is identical to the value used internally to drive the
VCA (Voltage Controlled Amplifier) circuitry inside Etherwave Theremin.
VOLUME CV OUT (TS): 0V to 10V
GATE OUT
The Gate Signal is a specific type of Control Voltage. A gate is often used
to initiate and sustain an event. Pressing a key on a synthesizer keyboard
is a perfect example of a gate; the gate is active once the key is depressed
and remains active until the key is released. While there are no keys on the
theremin, a gate signal will be generated while a note is being played—that
is, when the VOLUME CV OUT value is greater than zero volts.
VOLUME CV OUT (TS): 0V (O) to 10V (On)
POWER
+12V DC
Plug only the power supply that came with your Etherwave
Theremin into this connector. Connect the other end to a
properly wired and grounded wall outlet.
POWER
Pressing the POWER button turns your instrument On. While
Etherwave Theremin is On, the POWER LED indicator on the
front panel will remain lit. When the POWER LED indicator is
dark, the instrument is O. Before turning Etherwave Theremin
On, be sure that the correct power supply is already connected,
and that the volume of any amplifier or monitoring system has
been turned down. You may also wish to lower the amplifier or
monitoring system volume level before switching Etherwave
Theremin O.
NOTE: This was mentioned earlier in this manual, but it is worth
repeating: because the player’s entire body acts as the ground in the
LC (Inductance/Capacitance) circuitry at the heart of the Etherwave
Theremin, a properly grounded connection is required for stable
operation. However, when using a well-grounded (earthed) Etherwave
Theremin with a well-grounded (earthed) amplifier, it is possible to
introduce a ground loop. In this case, it may be necessary to use a
ground-lifting device on either Etherwave Theremin or the amplifier—
but not both—to eliminate the ground loop.
