Radial JS2 Passive Mic Splitter - The Ultimate Sound Splitting Solution
Passive 2-way Microphone Splitter
The JS2 is a high-performance balanced mic-level splitter that sends a signal to multiple destinations simultaneously. It features one transformer-isolated output and two direct outputs.
Portable and Versatile - Ideal for Stage or Studio
The JS2 is a professional mic splitter that splits a single source to multiple destinations without signal degradation or noise. A premium Jensen transformer provides galvanic isolation, eliminating buzz and hum from ground loops. It maintains an extremely wide bandwidth with ultra-low distortion and phase shift. Ground lifts on the outputs further reduce noise, and an input pad allows line-level sources to be connected. Both the JS2 and the JS3 can be rack-mounted for touring and installation purposes, with up to eight fitting in the Radial J-Rak.
Key Features:
- • Split One Microphone Signal to Three Destinations Simultaneously
- • Jensen Transformer for Exceptional Audio Quality
- • Eliminates Hum and Buzz from Ground Loops
Applications:
2-Way Split - Perfect for Multiple Mixers
The Radial JS2 is the ideal interface for splitting a microphone to feed more than one mixer at the same time. 100% isolation eliminates potential ground loops between the two consoles for a quiet performance. The main output provides a 48V phantom power return path to the mic.
Compare Two Mic Preamps - Ideal for Studio Use
In the studio, comparing the sound of two mic preamps on a particular voice is often beneficial. The JS2 is perfect for this as it doesn't color the sound of the mic or add distortion. Its plug & play simplicity makes setup quick.
Features:
- Send one microphone signal to three destinations simultaneously
- Jensen transformer-equipped for exceptional audio quality
- Eliminates hum and buzz caused by ground loops
- Single isolated output provides optimal noise rejection
- Input Pad
Reduces input by 30dB to allow +4dB line-level devices to be connected. - XLR Mic Input
Standard 600 main input. - Direct Thru-1
600 connects to main PA with phantom-power return path to microphone. - No Slip Pad
Provides electrical & mechanical isolation and keeps the unit from sliding around. - Book End Design
Creates a protective zone around the jacks and switches. - Direct Thru-2
600 Second direct out can connect to recording or monitor systems. On the JS3 this output is transformer-isolated. - Ground Lift
Disconnects the ground path at the XLR output. - XLR Output
Isolated 600 connects to a recording or broadcast system without noise. - 14-Gauge Steel
I-beam enclosure makes it impossible to torque the PC board; eliminates cold solder joints. - Warranty: Radial 3-year, transferable
