JBL Synthesis range
SDA-7120
The JBL Synthesis SDA-7120 is a 7-channel power amplifier intended for a coherent multichannel cinema rack where channel matching and installation efficiency matter.

Where it fits best
JBL Synthesis LCR/surround systems where Dante, Class G efficiency and honest all-channel ratings matter.
What to pay attention to
Dynamic/two-channel figures are not the same as seven-channel output. Size the system from the all-channels-driven rating and speaker sensitivity.
