The R-4 Rack is the perfect solution when a little extra rack space is needed. With 4U of rack space, the R-4 provides sufficient space for wireless microphone signal distribution and receivers, compact rack mount digital mixers, or quick-connect rack panels. 
 
When ordered with an enclosed synth or mixer cart, the R-4 can be mounted to the top shelf by Pageantry Innovations, or added later a la carte with a bit of DIY installation. All required hardware is included with al la carte R-4 Racks.
