Note: Power handling for transducers is based on an AES long
term power testing standard conducted for 100 hours full power,
free air.
for additional signal routing. To ensure long term reli-
ability and performance, the amplifiers are mounted
on a massive heat sink, which is convection cooled and
dramatically extends the life expectancy of the heat-
producing components.
The SR1530 cabinet is constructed using both multi-
layered plywood and pressure injected structural resin.
The combination provides a robust enclosure system
with useful ergonomic features. There are three-part
cast aluminum handles on each side of the enclosure
for easy carrying and setup. Handles are located on the
top and bottom of the cabinet for easy movement and
relocation. A full size, oval punched, weather resistant
steel grille protects the front of the cabinet.
