JD7 Guitar Distro & Splitter
Studio Guitar Distribution and Splitting
The JD7? is a guitar signal splitter that is able to drive as many as seven amplifiers at the same time without introducing noise, signal loss, or hum and buzz from ground loops.
Drive up to 7 amplifiers and 2 effects loops at the same time
Jensen transformer isolation eliminates hum and buzz
Built-in Radial Direct box and Reamp capabilities
Drag control load correction for natural tone
Natural tone, quiet operation
The JD7 allows you to feed up to seven amplifiers simultaneously, with premium Jensen transformers on the outputs that ensure distortion-free signal transfer while blocking hum and buzz from ground loops. To help retain the natural tone of your instrument, Drag control load correction is also featured on the input so you won't lose the tone and feel of connecting your guitar directly to an amplifier.
Record direct and Reamp through multiple amps
The JD7 has a built-in Radial DI box, so you can take a clean guitar track directly to your recording interface while simultaneously playing through multiple amplifiers. A Reamp input allows you to send your recorded guitar track from your recording device back through any or all of your amps, so you can focus on the performance and have the freedom to tweak your amps and microphones later on.
JD7 Specifications
The Radial JD7 is a combination distribution amplifier, direct box and Reamp. As such there are a myriad of specifications that one may look at when determining suitability. The Radial JD7 incorporates 100% discrete parts, class-A circuitry and Jensen audio transformers in the guitar signal path to deliver near perfect unity gain with plenty of headroom and low noise. The fidelity of the audio and ‘feel’ can only truly be judged by plugging it in and closing your eyes!
