Product Description

"Hum" in an audio system is often caused by loop effects which act like antennas. These loops can easily pick up a 60 Hz (or higher harmonics) hum transmitted by electrical wiring. Typically, these loops are connected via grounds, more commonly called "ground loops". The safest way to eliminate unwanted noise is with the CleanBOX II. Some examples of Ground Loops:The power ground of a synthesizer, connected to the signal ground of the synth, into a mixer?s ground, then into a mixer's power ground.The signal ground of a send effect (reverb, delay) into a mixer, and the connecting power grounds of the mixer and the unit.The power ground of a guitar amplifier, connected to a signal processor which has a second guitar amplifier on the other channel, and then the second guitar amp?s power ground.The CleanBOX II easily removes ground loops without any signal degradation. ...

Product Description

Multi-mode direct box functions as 2 separate direct boxes in stereo mode. In mono mode 2 high-impedance, unbalanced input signals can be combined into one low-impedance, balanced output mono channel to conserve channels in a snake. Also in mono mode, 2 high-impedance unbalanced signals can be combined into one low-impedance balanced signal, isolated and split into 2 separate mono output signals. Comes with 2 shunts on the input jacks to eliminate feedback noise. ... Read more

Product Description

The Radial X-Amp presents the engineer/producer/guitarist with an innovative and creative tool that allows a prerecorded track from a line level device to drive 2 guitar amplifiers or effect pedals simultaneously. The X-Amp employs a unique Class-A circuit design that has been optimized for use with guitars. Using the X-Amp is easy: One would, for instance, record a dry track using a high-quality direct box, then send this track from the recorder to the X-amp and then to either guitar amps, effect pedals or combinations thereof.Recording using the X-Amp has many benefits: once the basic track has been recorded, replacing or adding tracks can be done well after the session player has gone home. This eliminates tiresome repetition and assures a fresh vibrant performance on the final recording. Furthermore, by driving 2 amps at the same time, new sounds and textures can be created allowing the engineer -- producer to make artistic decisions as the recording progresses. Features include balanced line level input with LED peak indicator and level control, Class-A circuit topology for optimal reach and frequency response, direct and isolated guitar amplifier outputs, 180° polarity reverse to bring both amps into phase, and dual ground lift options for noise-free operation.Built like a tank to provide years of trouble-free performance, the X-Amp boasts a welded I-beam internal skeleton with a... ...

Product Description

Considered by many to be one of the finest passive-operation direct boxes available, this DI employs a Jensen isolation transformer for optimum audio performance. 60-cycle ground loop elimination and adept handling of high-output, active instruments and keyboards make it discrete and versatile. Steel I-beam construction, baked enamel finish, and protected faceplate mean it's built to survive.The Radial JDI passive direct box employs the Jensen JT-DBE transformer as its main drive engine. The Jensen DBE transformer employs a laminated nickel core with low-permeability and no magnetic memory, therefore eliminating phase distortion caused by the disruption of fundamentals and harmonics.The distinctive book-end design protects the switches against damage from abuse by providing a protective zone on both I/O panels. A baked enamel finish resists scratching while a no-slip rubberized pad on the bottom stops the JDI from moving around and aids isolation. Inside, the JDI features compound, welded I beam construction that protects the sensitive electronics from outside stress. The internal skeletal frame is locked together with 4 hex screws.The input panel features a 1/4" instrument input and traditional thru-put. An innovative merge function allows the thru-put to be converted to a second input to allow stereo to mono summing. This is useful for interface with stereo sources such as keyboards or CD players in live... ... Read more
