Radial JS3 Microphone Splitter

Passive 3-way Microphone Splitter

The JS3™ is a high performance balanced mic-level splitter designed to send a signal to multiple destinations simultaneously, with two transformer-isolated outputs and one direct output.

Portable mic splitting on stage or in the studio
The JS3 is a professional mic splitter designed to split a single source to multiple destinations simultaneously without signal degradation or noise. A premium Jensen transformer inside provides galvanic isolation to eliminate buzz and hum from ground loops, while maintaining an extremely wide bandwidth with ultra-low distortion and phase shift. Ground lifts on the outputs help further reduce noise, while an input pad allows line-level sources to connected as well. 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.

JS3 Applications

Using the JS3 to feed three mixers
Sometimes, you need to feed the main mixer, stage monitors and a recorder at the same time. The JS3 makes hook-up easy with XLR input, direct out and two isolated outputs. These eliminate ground loops when connecting multiple mixers at the same time.

Features:

• Send one microphone signal to three destinations simultaneously
• Jensen transformer-equipped for exceptional audio quality
• Eliminates hum and buzz caused by ground loops
• Dual isolated outputs provide optimal noise rejection
• Input Pad
  Reduces input by 30dB to allow +4dB line-level devices to be connected
• XLR Mic Input
  Standard 6000 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.
• Ground Lift
  Disconnects the ground path at the XLR output.
• XLR Outputs
  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.
