Description
The Radial JDX 48 Reactor is a direct box designed to capture the explosive dynamics and warmth of an electric guitar amplifier by connecting between the guitar amp head and speaker cabinet. This delivers a sound that is similar to a well-placed microphone while eliminating the frustrating inconsistencies.
Features:
- Captures sound of both the head and the cabinet
- Delivers consistent tone - show after show
- Works equally well on electric guitar and bass
- Can be used with 48V phantom power or DC supply
The design begins with 100% discrete class-A circuitry and a transformer-coupled 'reactive load' that captures both the sound from the amp head along with the back electromagnetic impulse from the loudspeaker. This produces a more realistic rendering than the usual resistive pad offered by other manufacturers. The signal is then processed via a carefully designed multi-stage filter to emulate the tone of a 4x12 half stack cabinet.
In use, the JDX 48 delivers greater consistency over a typical microphone as irregularities such as mic placement and varying acoustics no longer play the dominant role on stage. This is most appreciated when using in-ear monitors as the tone remains consistent from one show to the next, resulting in shorter setup times and a more comfortable audio feed for the artist.
Although originally designed for guitar, the JDX has also become a favorite on bass. The clarity and punch in the lower midrange delivers a tone that is reminiscent of an Ampeg SVT connected to an 8x10 cabinet. On guitar it sounds as if you have a Shure SM57 in front of a Marshall half-stack. This new version also offers greater power handling for 300 watt amps and extended low end for deep bass frequencies.
