MAKING CONNECTIONS
Before making connections ensure your amplifiers
are either turned off or volume turned down. This will
avoid unpleasant plug-in transients that could shorten
the lifespan of more sensitive components. Set all of
the ground lift and 180º polarity reverse switches to
the down position. Plug in your 9V power supply (not
included). This should be a standard ‘Boss’ type guitar
pedal adaptor or 9V supply from a multi-pedal power
brick with a center negative connection. There is no
power switch on the Shotgun. Once the power supply
is connected, it will turn on and the top panel LED will
illuminate to let you know power is on.
A handy cable lock is also available that will help
prevent accidentally disconnecting the power. To
use, unscrew the lock using a hex key, pass the
wire through the clamp hole and retighten.
Connecting to and from the Shotgun is done using
standard ¼" hi-Z coaxial guitar cables. Better
quality, low-capacitance cables with 90% to 100%
shield will improve signal-to-noise. Keeping cables
as short as possible on the input side will further
reduce susceptibility to noise. Once the signal has
passed through the Shotgun, longer cables may
be used as the Shotgun will buffer the signal and
lower the impedance to enable cable distances up
to 15 meters (50') without appreciable noise. The
Shotgun is a unity gain device. Whatever signal you
put in, it will put out - producing the same relative
output volume.

The Shotgun requires a 9 volt power
supply with a negative center.
