Shure SB913A 3-AAA Battery Sled for ADX1, ADXR

Battery sled that lets three AAA cells power an Axient Digital ADX1 bodypack transmitter or an Axient Digital PSM ADXR bodypack receiver. Load the cells, close the sled cover, slide it into the battery compartment, and secure the outer door. Ruggedly built, it provides a standard-cell backup alongside Shure rechargeable batteries. Unlike the earlier SB913, it also supports the ADXR receiver.
