Disposal and Recycle
When switched on, the Sound Bullet
generates pink noise, which is
routed to the male XLR by default.
Press the
TO button to route the
generator to the 1/4” Jack and the
internal speaker/Mini-Jack.
A 1 kHz sine wave can be selected
by pressing the
SEL button.
The generator’s output can be
adjusted to three levels:
-40, -20 and -10 dBu.
The Sound Bullet checks for Phantom Power
voltage, which is individually metered on pins 2
and 3 of the male XLR. Two dedicated LEDs will
illuminate according to the P48 voltage standard
(48V ±4V).
If the voltage detected is below 44V and above 24V,
the LEDs will ash slowly.

Product Overview

1
The internal speaker (3a) reproduces signals
present on the female XLR or the 1/4” Jack.
The speaker and Mini-Jack output
(3b) share the same internal amplier
whose output level is adjusted by the
side thumbwheel. If a 3.5mm Jack
(headphones) is plugged into the Mini-
Jack port, the speaker mutes and its
output is routed to the Mini-Jack.
Routing the internal generator to the
1/4” Jack (by pressing
TO) will also route
it to the speaker and Mini-Jack.
Two LEDs will illuminate according to
the RMS amplitude of the signal present
on the female XLR. The
SG LED is lit when the
signal exceeds -20dBu RMS, and the
PK LED
lights up when the signal exceeds +10dBu.

An XLR cable can be plugged into either end of
the Sound Bullet in order to conduct a continuity
test on the XLR pins 1, 2 and 3. To enter (and exit)
this function, press and hold the
SEL button for 2
seconds. To cycle the pin under test press the
TO
button.

Examples of Use
The Sound Bullet can test lines of a multicore
line system connected to the inputs of a sound
console. Activating Phantom Power on the input
channels desired to be checked will allow for
simultaneous test of all three cores of the XLR
line. Simply switch on the Sound Bullet, which
will start to generate pink noise, and plug it into
the XLR line. The operator at the sound console
will listen out for the pink noise while the sound
engineer on the other end will check the 48V
indication on the Sound Bullet (see table). This
will determine if all pins of each XLR line are
functional, and conrm that the patch is correct.
Line-check a multicore
Outputting an unbalanced signal via the 1/4”
jack is very useful for quickly conrming one or
multiple DI boxes connected to a mixing console.
The provided 1/4” Jack-Jack adaptor
allows you to quickly plug the
Sound Bullet straight into the hi-Z
input of a DI Box.
Simply switch on the Sound Bullet, which will
start to generate pink noise. Direct the generator
to the 1/4” Jack by pressing
TO. As a conrmation,
you’ll hear pink noise coming out of the speaker*,
along with the function LED turning blue. With
the Jack adaptor inserted, plug the Sound Bullet
into the DI box and check for pink noise being
received at the mixing console.
*Adjusting the speaker’s volume by the thumbwheel
will not affect the output of the 1/4” Jack.

Test a DI box
The Sound Bullet can be used as a quick
diagnostic tool to troubleshoot FX pedalboards.
Press the TO button to switch between sending
and receiving audio via the 1/4” Jack. This will
allow you to quickly inject a signal into the input
(1, 2) of FX pedals or listen to their outputs (3).
By tapping into each segment of the FX chain you
can effectively detect which pedal contributes to
the issue; testing out one effect unit at a time.

Troubleshoot pedalboards
Thanks to its internal speaker, your Sound Bullet
can test balanced feeds layed out for wireless or
hardwired IEMs, self-powered speakers or speaker
amps/processors, recording and camera feeds.
When the Sound Bullet is switched on, signals
present on the female XLR or 1/4” Jack are
reproduced by the internal speaker by default.
Make sure the mixing console is sending either
pink noise, music or any other type of audio into
the line you are testing and simply plug that line
into the Sound Bullet.
The input meter on the Sound Bullet will give you
indication of signal presence ‘
SG’ or of the signal
being very loud, ‘
PK’. This feature is very useful
in noisy environments, or if you can’t get your ear
close enough to the Sound Bullet’s speaker.
If you require a more accurate listening to the
signal, plug your headphones into the Sound
Bullet’s Mini-Jack output and adjust its output
level with the volume thumbwheel on the side.
Check XLR feeds
The LED by the Micro-USB port indicates
the charging state while the Sound Bullet is being
charged. The LED lights up red while the battery
is charging, and turns off when it’s fully charged.
The function LED next to the
SEL button will blink
white as a warning when the
battery is:
• Low
• Discharged
Consider recharging your Sound Bullet when the
rst ‘low battery’ warnings appear.
The device may be used while ‘discharged’,
however doing so may damage the battery and
the main functions will stop after a few seconds.

Charge your Sound Bullet using the provided
Micro-USB cable. Please use a standard USB
charger (5V, 500mA). Charging your Sound Bullet
takes around one hour and the device can be used
while charging.
