Radial Engineering JD7 1x7 Guitar Signal Distribution Amplifier

Guitar Signal Splitter & Distro with 7 Outputs, DI Box and X-Amp Reamper

The Radial JD7 Injector is a creative recording tool disguised as a guitar signal distribution amplifier that allows a guitar signal to drive as many as seven amplifiers simultaneously without loss or coloration.

Front panel control makes selecting amplifiers, ground paths and polarity (phase reversal) easy. The JD7 utilizes a newly developed Class-A audio signal path that has been optimized for use with electric guitars and is 100% discreet (no opamps or chips) producing the most accurate and faithful signal at each output. To eliminate such problems as 60 cycle hum caused by ground loops without signal degradation, the world's finest audio transformers by Jensen are employed.

The Radial JD7 also features a 600-Ohm balanced direct output to allow the engineer to record a dry guitar track or to use the JD7 as a direct box. A balanced input allows a pre-recorded track to be sent back into the JD7 which can then drive amplifiers, effect pedals and other devices.
