While the RSA-500 subwoofer amplifier was primarily designed for use with the RW5802 in-wall subwoofer, it also features custom settings for the AW-800-SW outdoor subwoofer. EQ switch for use with different subwoofersSelectable signal-sensing or voltage triggered auto-on/off circuit300 watts continuous into 8 ohms or 500 watts continuous into 4 ohmsLine and speaker level inputsRack ears includedThis high-powered device will drive up to two of any of these subwoofer modules and delivers 300 watts into an 8-ohm load (one subwoofer module) and 500 watts into a 4-ohm load (two subwoofer modules). It also comes with rack ears for fast and secure placement into any standard 19-inch rack.To keep end users from inadvertently tampering with performance levels, the majority of the RSA-500"s controls are housed on its rear panel. The fuse is also included on the back for quick and easy replacement. A detachable IEC power cord allows for the simple removal and reinstallation of the entire amplifier unit. The RSA-500 was also designed to "play nice" by offering standard input/output connectivity that will support any type of system.
