CONNECTIONS
The INPUT “Combo” jack allows for either XLR or ¼-inch TRS input connections.
The XLR input connection is used primarily for balanced microphone input. Pin 2 is
positive, pin 3 is negative, and pin 1 is ground. +48 Volt phantom power (when en-
abled) is supplied to pins 2 and 3. Pin 1 acts the ground return. Do not lift pin 1 when
using phantom power. If you are using the XLR Input with a balanced line level signal
or a microphone that does not require phantom power, make sure that phantom power
is turned off. This input can handle signals up to +14dBu before clipping.
The ¼-inch input connection is used for high impedance microphones or low line level
unbalanced (TS) signals. The high fixed input impedance minimizes microphone load-
ing. This input can handle input signals up to +15dBu.
The INSERT jack allows you to add external processing between the Preamp and
Auto-Tune EFX section. This also gives you a direct out from the preamp (pre Auto-
Tune) and allows you to directly drive the Auto-Tune EFX section if you are using an
external preamp or line level source.
The REMOTE jack allows for external control of the Bypass and Preset switch func-
tions. The Preamp section is not affected. If you use an external footswitch with two
switches through a ¼-inch TRS connection, then the switch connected to the Tip tog-
gles the Bypass function and the switch connected to the Ring lets you step through
the Presets. If you plug a single remote footswitch with a Mono ¼-inch (TS) connection
into the jack it will step through the Presets. If you want to toggle Bypass only with a
single remote footswitch, use a ¼-inch TRS connection that has only the tip and sleeve
connected (floating ring).
Momentary type footswitches should be used that are normally open and close only
when pushed. The remote footswitch will act just like the front panel switches.
