STAGE BUG SB48UB
STAGEBUG SB-48 UB @ Phantom Power Supply Box
The Radial SB-48UB is a unique 48V phantom power supply that enables the artist to power a condenser microphone and then send the balanced signal into the unbalanced signal into a stage amplifier or effect pedal like a Radial PZ-DI acoustic preamp.
The challenge when using a condenser microphone with a preamp pedal, direct box or stage amp is that most of these only have unbalanced inputs. And as most phantom power supplies are only equipped with balanced inputs and outputs, making a proper connection is often difficult or impossible due to the impedance and level mismatch.
The SB-48UB is a single channel phantom power generator that converts the power from a 15VDC supply to 48 Volts for use with a condenser microphone or active direct box. Inside, the SB48-UB converts the signal to both a lo-Z balanced XLR output and a hi-Z unbalanced ¼" out. Both outputs may be used concurrently whereby the XLR could feed the PA while the ¼" out could feed a stage amp or pedalboard. Click here to download the manual
| Circuit type: | Non-radiating phantom power supply |
| Number of channels: | Single channel for one microphone |
| XLR connector: | Lo-Z balanced microphone level output; AES standard pin-1=ground, pin-2=hot (+), pin-3=cold (-) |
| ¼” connector: | Hi-Z unbalanced instrument level output; tip=hot, sleeve=ground. |
| Phantom output: | Switchable +48 / +12 volts DC |
| Power supply: | 15VDC / 400mA external supply included |
- ¼” OUT – Unbalanced ‘guitar level’ output used to feed a stage amp or guitar effects pedals using standard coaxial cable.
- XLR-M OUTPUT: Used to connect the mic signal to the mixing console or preamp. Equipped with a capacitor to block other sourc- es of phantom power to prevent damage to your mic or direct box.
- XLR-F INPUT: Used to connect your microphone to the StageBug SB-48UB. Phantom power is generated inside the SB-48UB and in- jected into the mic capsule via the XLR-F connectors and mic cable.
- +12/48V SWITCH: Used to change the phantom supply from the standard +48 volts to +12 volts for speciality microphones.
- POWER INPUT AND LED: The power jack accepts the included 15VDC/400mA power adapter. The LED illuminates when the power supply is connected and the SB-48UB is active.
- CABLE CLAMP: Used to lock down the power supply cable and prevent accidental disconnection.
- FULL-BOTTOM NO-SLIP PAD: This provides electrical isolation and plenty of ‘stay-put’ friction to keep the SB-48UB in one place.
