The Radial Engineering 4-Playâ„¢ is a multi-channel direct box that has been specifically developed for multi-instrumentalists to enable them to quickly change instruments on stage, without disrupting the audio engineer or creating a mess of cable spaghetti to contend with.

It works like this: Mute your guitar using the mute footswitch. Then, disconnect your guitar and reconnect your mandolin. Hit the output selector footswitch to advance the output from 1 to 2 and then turn the audio back on by hitting the mute footswitch again. It’s that easy. Super-bright LED status indicators tell you which output is active, further simplifying the changeover process.

There are four balanced DI outputs. Each one is equipped with a ground lift switch to eliminate hum and buzz caused by ground loops. With four outputs, each instrument has its own dedicated channel in the PA and monitors. This way, each instrument can be set with its own level, specific EQ and with whatever effects may need to be applied. Best of all, the engineer does not have to contend with the switch-overs on stage as only one output is active at any one time. This eliminates frantic hand signals and the need to coordinate muting and unmuting audio channels at the monitor desk or front of house. A dedicated tuner output is always on to allow quick on-the-fly adjustments or to tune between songs.

Built Radial tough, the 4-Play is made from heavy 14-gauge steel for added rigidity and greater immunity against stray magnetic fields.
