SDA-4600

4-channel Bridgeable Class D Amplifier

The SDA-4600 is a versatile 4-channel Class D power amplifier designed to deliver maximum power while taking up minimal rack space. Each channel is rated to deliver 600W into 8 ohms and adjacent channel pairs can be bridged to deliver 1,200W into 8 ohms. This flexible channel configuration makes this an ideal amplifier to power larger LCRs and subwoofers in JBL Synthesis immersive audio systems. Powerful built-in DSP allows for custom loudspeaker tuning and full external control allows for complete and easy system integration.
