Radial 4 Play Multi-Output DI Box

• Quick change-over DI for multi-instrumentalists
• Switch between four outputs using a single footswitch
• Four DI outputs for control over each instrument
• Ground lift switches to eliminate hum and buzz

The 4-Play begins with a standard ¼" input for acoustic guitar,  mandolin, fiddle or bass. In fact, it works great on just about any  instrument. A mute footswitch lets you silence the switcher when  connecting or disconnecting the instrument. The signal is then routed to  a selector footswitch that sequentially activates up to four outputs  allowing each instrument to have its own dedicated channel on the PA.  You simply mute the 4-Play, connect the desired instrument and then use  the footswitch to select the output. High visibility LED indicators  provide clear visual feedback to let you know which output is active.

Radial Tech Team associate Mike Bauer explains: "When you are on a  busy stage, switching instruments can pose several challenges. When  sharing the same direct box, switching between an acoustic guitar and  mandolin requires both the FOH engineer and monitor engineer to mute the  active mixer channel in order to avoid damaging plug-in transients and  painful pops for the audience. You then need to alter the EQ and adjust  the level to adapt it for each instrument. Alternatively, when using  separate DI boxes, you end up with a bunch of wires connected to each  instrument which often get tangled. Ask any stage tech and they will  tell you that the preferred approach is to use a single cable and  manually switch between instruments. Then, because the artist can mute  the instrument on stage, you avoid having to flag down the FOH and  monitor engineers between each changeover. Since each instrument is now  connected to a dedicated channel, the signal level, EQ and effects can  be predetermined and optimized without having to make radical changes  every time an instrument is changed.  With so many auxiliary musicians  onstage these days, there has never been a more appropriate time for  this type of solution."

The 4-Play features four balanced XLR outputs, each of which is  equipped with a ground lift switch to help eliminate hum and buzz caused  by ground loops. All of the connectors are made from glass-filled nylon  for exceptional durability and isolation and feature nickel-silver  contacts that will not tarnish over time. Two 'set & forget'  switches allow the user to increase the range of the selector footswitch  to 2, 3 or 4 outputs. There is also a dedicated tuner out that can be  assigned to be always on, or function in tandem with the mute switch for  quick on-the-fly adjustments.

Built Radial tough, the 4-Play is made from heavy 14-gauge steel for  added rigidity and greater rejection of stray magnetic fields. It  employs a standard Boss-style 9V power supply (not included) and is  equipped with a cable lock to prevent accidental disconnection.
