The SDA-7120 is a high-performance 7-channel Class G power amplifier designed to deliver audiophile performance and incredibly powerful dynamics. Each channel is rated to deliver 100W into 8 ohms and 140W into 4 ohms with all channels driven. With only two channels driven, 225W of power is on tap with a 4 ohm load. This combination of high power and low distortion make this the ideal solution for LCR and surround loudspeakers in JBL Synthesis immersive audio systems. DANTE digital audio networking allows connection of the SDA-7120 to a compatible DANTE-enabled surround processor via just a single Ethernet cable and full external control allows for complete and easy system integration.
