EXP INPUT Jack
The Ring Thing allows for expression pedal input via the EXP input jack. The expression
pedal must have a Tip-Ring-Sleeve plug attached to it. It is important that the expression
pedal have the correct polarity. The tip of the plug must be connected to the wiper of the
potentiometer inside the expression pedal. If you are not sure what type of expression
pedal to use, try to purchase one with a polarity switch so that it will work with many
different types of instruments. Some suggested Expression Pedals: M-Audio EX-P, Moog
EP-2, Roland EV-5 or Boss FV-500L. You may also connect a control voltage to this jack.
The Control Voltage range must be between 0 V to 5 V. Here’s what you can do with an
expression pedal:
RM/UB/LB Modes
: An expression pedal can control the ring modulator
frequency, replacing or working in conjunction with the COARSE and FINE knobs
or the automatic tuning function.
To use an expression in these modes, the
FINE knob must be set fully counter-clockwise.
Setting the FINE knob to
anywhere other than fully counter-clockwise will disable the expression pedal
function. Use the COARSE knob to set the toe down position or the total range of
the Exp. Pedal. The expression pedal range can also be set by automatically
tuning to a note you play on your instrument using the PRESET/TUNE FSW.
When doing this, the toe-down position will be the tuned frequency.
Pitch-Shift Mode:
An expression pedal can control the pitch shift amount, just
like a whammy pedal. The COARSE and FINE knob settings determine the upper
limit or toe down position of the expression pedal. The toe up position is always
zero pitch shift. If you have modulation set up on your pitch shift, the expression
pedal will bend notes with the modulation.
In all modes, you can save the expression pedal’s setting along with all knob settings.
MONO/L and R OUTPUT Jacks
When using the Ring Thing in a mono output configuration, we suggest you use the
MONO/L output. When using it in a stereo output configuration, use both the MONO/L and
R output jacks.
In both RM and PS modes, the effect, after the BLEND knob, is sent to the L output jack
and the R output is 100% dry signal. In both UB and LB modes one sideband is sent to
each output. In UB mode, the upper band is output from the L output and the lower band
is sent out the R output. In LB mode, the lower band is output from L output and the
upper band is sent to the R output.
