What is the RDL SR-4?
The RDL SR-4 is a universal steel chassis that mounts up to seven RDL STICK-ON modules to a backboard, wall or nearly any other support. It keeps distributed audio electronics organized in equipment rooms and AV installations.
How does it work?

The SR-4 holds 4 STICK-ON power amplifiers or 7 standard STICK-ON modules, and TX series modules may also be mounted. Four cable entry ports, two on the bottom and one on each side, accept cabling or any RDL AMS accessory, and hole plugs cover unused wiring holes. Two rear mounting holes align with an RDL WB-2U or a standard double US electrical box for wall mounting with rear wire entry. For 19-inch rack mounting, see the RDL STR-19A racking system.
