The Instrument Inputs - Radial Engineering JX44 V2 Owner's Manual

True to the Music
GETTING STARTED: POWERING THE JX44
The JX44 features a rear-panel IEC input for the included power supply cable. The internal power supply is
compatible for use in multiple regions, from 100-240VAC at 50/60Hz. For international touring applications, simply
swap out the IEC cable for one that matches the outlet type at your country of destination.
The JX44 has no power on/off switch: once it is connected to a power source, the front panel LED indicators for
Input-1 and Output-A will illuminate and the unit will be ready for use.

THE INSTRUMENT INPUTS

The JX44 is equipped with four instrument inputs, accessible via redundant connectors on both the front and rear
panels. These inputs employ Radial's proprietary Class-A buffer circuit for superior audio quality and low noise,
with gold-contact connectors for optimal signal transfer. If your setup includes wireless guitar systems, connect the
outputs of your recievers to the instrument inputs, otherwise you can connect your guitars or basses directly to the
JX44. In either case, use standard 1/4" unbalanced instrument cables, and keep your cable runs as short as you
reasonably can.
The instrument inputs, mirrored on the front and rear panels of the JX44
You can activate any input on the JX44 by pressing the corresponding front-panel ON switch. Each switch is backlit
and will illuminate when the input is selected. To deselect any instrument, press the ON switch a second time. The
JX44 allows any combination of inputs to be active simultaneously, which can be particularly helpful for guitar techs
that need to perform a quick instrument hand-off between songs; by making two instruments active they can let one
guitar ring out at the end of the first song, while ensuring the next guitar is ready to play as soon as it reaches the
artist's hands.
Note that the front panel inputs have priority over the rear panel connectors - as soon as you plug a cable into
one of the front panel input jacks the corresponding input on the rear panel will be deactivated. This allows you to
troubleshoot or make changes on the fly without the need to fuss with cables in the back of your equipment rack
during a performance.
Instrument Input-4 is unique in that it may be exclusively assigned to the JX44's direct output. See the direct output
section of this manual for more information on using this feature.
