REAMP JCR

Studio Reamper

Overview

The Radial Engineering Reamp JCR is a passive reamper that allows you to take a prerecorded track and send it back to a guitar or bass amplifier and re-record it. The benefits are tremendous: instead of worrying about the sound of the track, you can focus your attention on getting the best musical performance. Once the performance has been captured, you can reamp the track even in the absence of the guitarist by moving the mics around the room, trying various amplifiers, or introducing effects. Additionally, you can also reamp the track later as the production develops. This reamper features the original reamp circuit designed by John Cuniberti. It features a 100% passive design with John's original custom-wound transformer and circuit that are made in the USA. It also features separate XLR and 1/4" TRS input connectors, variable output level, and a 3-position filter that lets you tame excessive highs, warm up the lows, or simply bypass if you want to revert to the original circuit. An on-board mute function has also been added to let you shut off the signal going to the amps while making adjustments or moving mics around the studio.

Features

Highlights

• Lets you re-record tracks through a guitar or bass amp

• Original reamp circuit designed by John Cuniberti

• Easy-to-use, plug-and-play passive design

• Improves productivity while expanding creative options

Connections

XLR Input

• Balanced input

• Connects from the output of your recording system to the Reamp JCR

1/4" TRS Input

• Connects from your recording workstation and is suitable for both lo-Z and hi-Z sources

• Wired in parallel with the XLR input

1/4" Output

• Unbalanced instrument level output

• Connects from the Reamp JCR to amps and effects

• Transformer isolated to eliminate hum and buzz caused by ground loops

Control Knobs and Buttons

Mute

• Silences the 1/4" output from the Reamp JCR going to the guitar or bass amplifier

Level

• Used to control the signal going from the Reamp JCR to the guitar or bass amplifier

• Sets the reamping output level to your amp

Filter

• Three-position switch used to select between preset EQ filter

• Low-pass (high-cut) setting to warm overly bright amps

• High-pass (low-cut) setting to clean up low end mud

• Flat setting to bypass the filters and go back to the original reamp circuit

Ground Lift

• Disconnects ground at the balanced inputs to eliminate hum and buzz caused by ground loops

180° Phase Invert

• Flips the electrical polarity of the output to compensate for amps or effects that invert the signal

Construction and Design

Steel Construction

• Heavy-duty 14-gauge steel construction for added durability and extra shielding against electromagnetic fields

Mil-Spec Circuit Board

• Double-sided PCB and full ground plane to assure low noise and high durability for trouble-free performance

Book-End Design

• Creates protective zone around connectors, switches, and potentiometers for added protection

Push Switches

• Feature durable metal outer casing

• Rated at over 20,000 cycles

Transformer

• Isolates and converts the impedance to properly feed the guitar amp

• Custom made in USA

No Slip Pad

• Full bottom surface neoprene pad provides electrical isolation and mechanical insulation

• Keeps the JCR Reamp from moving around when placed on the guitar amp

Baked Enamel Finish

• Keeps your JCR Reamp looking great for years
