Welcome - JBL SYNTHESIS SDA-7120 Quick Start Manual

Welcome

Thank you and Congratulations...
The JBL Synthesis SDA-2200 and SDA-7120 deliver dynamic Class G amplification with modern network capability,
audiophile sound and exceptional flexibility. With balanced and single ended inputs, RS232 and IP control as well
Dante™ audio networking, the SDA-2200 and SDA-7120 are superb choices for a broad range of applications.
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. The first power supply 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 incorporated up to full rated power output as required. This efficient design means additional
power is only used when required. Modern high-speed silicon allows this switch to take place well beyond the audio
bandwidth. Multiple output devices within the amplifier ensure your listening experience is powerful, dynamic and
crystal clear.
The SDA-2200 and SDA-7120 feature 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 Cat5e or Cat6 cable. Dante audio networking uses standard IP networks to
transmit high-quality, uncompressed multi-channel audio with near-zero latency. It is flexible, reliable, and
easy-to-manage and eliminates issues with interference, crosstalk and signal degradation associated with
analog cable.
