Powerful and dynamic
The Class G amplifier offers the best features of Class A and Class A/B designs. Class-A amplifiers do not suffer from crossover distortion at the lower levels, while offering an exceptional level of transparency and realism. The problem with a conventional class-A amplifier, however, is that they are not as effective as class-A/B amplifiers, which have the disadvantage of suffering from crossover distortion at lower levels, thus obscuring spatial detail and transparency.
Conventional Class-A designs do not suffer from crossover distortion and are exceptionally transparent, offering a high level of realism. However, an exclusively Class A design is extremely inefficient as it will always draw full power even with no signal to amplify, for this reason Class A amplifiers usually offer lower power. 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 obscures spatial detail and transparency.
Class G offers greater efficiency and transparency with less wasted thermal energy than Class A. As a hybrid car engine, Class G implements multiple power supplies instead of 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 exceeds the capability of this first power supply, the secondary supply is gradually brought up to full rated power as required. This makes for a very efficient design, as additional power is only used when needed. Modern high-speed silicon allows it to make this switch at speeds far beyond the audio bandwidth.
Flexible
The SDA-2200 features Dante™ audio networking, allowing you to connect to 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 networks use standard IP networks to transmit high-quality, uncompressed multi-channel audio with near-zero latency. It is the most flexible, reliable and easy-to-manage audio networking solution available, and provides the lowest cost of ownership by dramatically reducing cable and labour costs, as well as eliminating interference, cross-talk and signal degradation problems 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 safely stored in the Dante devices themselves, so they are automatically restored if a device is switched on and off.
