JBL Synthesis SDA-2200 2 Channel Class G Power Amplifier

The SDA-2200 is a high-performance 2-channel Class G power amplifier designed to deliver audiophile performance and incredibly powerful dynamics. Each channel is rated to deliver 200W into 8 ohms and 400W into 4 ohms, plus the amplifier can be bridged to deliver 1,100W into 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-2200 to a compatible DANTE-enabled surround processor via just a single Ethernet cable and full external control allows for complete and easy system integration.

Powerful and Dynamic

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.

Class G offers greater efficiency and transparency, with less wasted heat energy than class A. Like a hybrid car engine, Class G implements multiple power supplies rather than just a single supply. The first power supply is of lower power and within this region, the SDA-2200 runs in pure Class A, which has no crossover distortion. If a dynamic signal is received that goes beyond the capability of this first power supply, the secondary supply is gradually brought in up to full rated power output as required. This gives a very efficient design as additional power is only used when required. Modern high-speed silicon allows us the make this switch at speeds well beyond the audio bandwidth.

Flexible

The SDA-2200 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 standard IP networks 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 labour costs as well as eliminating issues with interference, crosstalk and signal degradation associated with analogue cable. The SDA-2200 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.
