INTRODUCTION
Thank you and congratulations on your purchase of the Radial
StageBugSB-48UBhi-Ztolo-Z signal converter and phantom power
supply.TheStageBugSB-48UBisauniquedevicethatmakesiteasy
to interface phantom powered microphones and direct boxes with
guitar-centric boxes of all types.
As most users will likely be familiar with the use of phantom power,
this manual has been kept short and to the point. We do however
suggest that you take a moment to give it a quick read so that you
familiarize yourself with the features that are built into the SB-48UB.
For more detailed information, please visit the FAQ section on the
Radial website. This is where we post questions and answers that
come from users after the product is released. If you do not find an
answer,weinviteyoutosendusanemailat[email protected] and
we will do our best to answer your query in short order.
The SB-48UB features a balanced microphone input with 48V phan-
tom to power a condenser microphone. What makes it unique is that
it is equipped with both balanced XLR and unbalanced 1/4” outputs.
The unbalanced ¼” output enables the artist to connect a condenser
microphone directly to devices that do not supply phantom power
such as the Radial PZ-Pre instrument preamp, a guitar effects pedal,
or a stage amplifier. Since both outputs may be used concurrently,
you can also send the dry mic signal directly to the PAsystem using
the XLR output.
GETTING SET
Before connecting the StageBug SB-48UB make sure the sound system and/or
stage amplifier is turned off and all levels are set to zero. This will avoid loud tran-
sients caused by the phantom voltage that could damage equipment downstream
suchas loudspeakers and tweeters. Do not turnup the volume until all connections
are made and the power supply is plugged in.
There is no power switch.As soon as you plug in the power supply, the SB-48UB
willspringto life and the front panel LEDwill illuminate. As an added safety feature,
theSB-48UB is equipped with a lockingcable clamp that lets you securethe power
supply cable so that it will not accidentally be dislodged. After use, remember to
turn down the volume levels on the PA and/or stage amp before you disconnect
cables or the power supply.
USING THE 12/48V SWITCH
You can change the phantom power voltage from 48 volts to 12 volts using the
set & forget recessed 12/48V switch on the side of the SB-48UB. Use a small
screwdriver to access the switch.
Whentheswitchisintheoutwardposition,theSB-48UBwillsupply48voltsofphan-
tom power. This is the normal setting for the majority of condenser microphones.
There are however, some miniature clip-on mics that are designed for use with 12
volt supplies. Pushing the 12/48V switch inward will supply the mic with 12 volts
of phantom power. Check the microphone manufacturer’s specification to ensure
this switch is set accordingly.

MAKING CONNECTIONS
Connect the source microphone to the SB-48UB’s balanced XLR
input.
There are two audio outputs to choose from. The unbalanced ¼”
output is designed for guitar type devices such as effects pedals or
stage amplifiers. It employs a step-up transformer to optimize the
impedance and signal level.
Using the unbalanced ¼” output with an instrument amplifier.
AMP
CONDENSER MIC
The balanced XLR male output follows the AES standard with pin-
1 ground, pin-2 (+), pin-3 (-). This would be used when the PA or
recording system cannot deliver its own phantom power to your
condenser microphone.
PA SYSTEM
CONDENSER MIC
Using the balanced XLR output to feed the PA system.
Once all of the connections are made and the power is on, slowly
turn up the volume to test and make sure everything is working. It
is good practice to always test at low volumes as this can further
avoid loud transients from harming your audio system should a
connection be faulty.
