JBL Synthesis SDA-7120 7-Channel Power Amplifier

The JBL Synthesis SDA-7120 delivers seven channels of dynamic Class G amplification. Class G amplification offers the best characteristics Class A and Class A/B designs. Conventional Class A designs do not suffer from crossover distortion and is exceptionally transparent offering a high level of realism. However, a solely Class A design is extremely inefficient as it will always be drawing full power even with no signal to amplify, for this reason, Class A amplifiers usually offer lower power output. Class AB design is much more common and far more efficient than pure Class A, but it suffers from crossover distortion at low levels which clouds spatial details and transparency.

The SDA-7120 features Dante™ audio networking so you can connect with the JBL Synthesis SDR-35 AVR and SDP-55 immersive surround sound processor as well as other Dante-enabled products over Ethernet-based networks via a Cat5e or Cat 6 cable. Dante audio networking uses a standard IP network to transmit high-quality, uncompressed multi-channel audio with near-zero latency. It's the most flexible, reliable, and easy-to-manage audio networking solution available, and provides the lowest cost of ownership by dramatically reducing cabling and labor costs as well as eliminating issues with interference, crosstalk and signal degradation associated with analog cable. The SDA-7120 is capable of receiving high-resolution audio via Dante. Signal routing and system configuration with Dante is fast, simple, and incredibly flexible. Once the network is configured, signal routing and other system settings are stored safely in the Dante devices themselves, so they are automatically restored if a device is power-cycled.
