JBL Synthesis SDA-2200

JBL SDA-2200 - A terrific power amplifier

JBL SDA-2200 is a dynamic Class G amplifier with a wealth of networking options, audiophile sound, and exceptional flexibility. With a full 2 x 200 watts into 8Ω and the first 2x 50 W in pure Class A, SDA-2200 delivers truly outstanding power and reliability, with harmonic distortion reduced to a mere 0.001%. Add to that the balanced and single-ended inputs, RS232, IP control and Dante™ audio networking, and SDA-2200 is an excellent choice for a wide range of applications.

HIGHLIGHTS:

• Dynamic Class G amplifier
• Dante™ audio networking
• 2 x 200 watts into 8Ω and 1100 watts bridged into 4Ω
• Balanced and single-ended inputs
• Trigger in and out
• Ethernet and RS232 control

Powerful and dynamic

The Class G amplifier offers the best qualities of Class A and Class A/B designs. Class A amplifiers do not suffer from crossover distortion at lower levels, while also offering an unusually high level of transparency and realism. The problem with a conventional Class A amplifier, however, is that it is not as efficient as Class A/B amplifiers, which on the other hand have the disadvantage of suffering from crossover distortion at lower levels, thereby clouding spatial detail and transparency.

Conventional Class A designs do not suffer from crossover distortion and are exceptionally transparent, offering a high level of realism. A pure Class A design, however, 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 output. Class AB designs are much more common and far more efficient than pure Class A, but they suffer from crossover distortion at low levels, which clouds spatial detail 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 instead of just a single supply. The first power supply is lower power, and within this region SDA-2200 operates 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 needed. This results in a highly efficient design, as additional power is only used when necessary. Modern high-speed silicon enables it to make this switch at speeds far beyond the audio bandwidth.

Flexible

SDA-2200 features Dante™ audio networking, allowing you to connect to 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 multichannel audio with near-zero latency. It is the most flexible, reliable, and easiest-to-manage audio networking solution available, and it provides the lowest cost of ownership by dramatically reducing cable and labor costs while eliminating problems with interference, crosstalk, and signal degradation associated with analog cable. SDA-2200 is capable of receiving high-resolution audio via Dante. Signal routing and system configuration with Dante are fast, simple, and incredibly flexible. Once the network is configured, signal routing and other system settings are securely stored in the Dante devices themselves, so they are automatically restored if a device is powered on and off.
