Maximum Power. Minimum Space.

The JBL name represents a long, proud history of invention, insight, and setting one industry standard after another. For over 67 years, JBL has brought the joy of sound to people around the globe, with products demanded by those seeking only the very best.

The expertise accumulated along the way is why JBL Synthesis gives your home theater the audio sophistication sought by directors, actors, recording artists, touring musicians, and others. In a JBL Synthesis home theater, you will discover a showcase of audio perfection. Backed by decades of award-winning engineering innovation offering an uncompromised, realistic sound that is revered by professionals and purists alike, JBL Synthesis systems deliver the ultimate in performance.

Digital Inputs With Analog Backup

With digital audio transport via HARMAN's proprietary BLU-Link, plus balanced analog inputs, the SDA 4600 gives you a tremendous audio advantage with much greater efficiency. The digital link from the SDEC 4500P to all SDA 4600 amplifiers in the system is handled by a single CAT5e cable daisy-chained between each unit. Up to 128 uncompressed high-resolution channels can be carried within the system, and up to 60 amplifiers can make up the signal chain. Simple hardware presets enable specific amplifier configurations for most JBL Synthesis System applications without any need for amplifier programming. The analog inputs are always available and if no BLU-Link digital input is connected the analog inputs automatically become active for standalone operation.

Amplifier Rack Density

Power points of 300W, 600W, or 1200W in 2-/4-/8-channel configurations - all in a 2-rack unit form factor. More channels in one box allow smaller infrastructure rooms that can reduce operational costs while giving you the utmost in installation flexibility. Harman patented DriveCore TM technology puts much more power from less space, resulting in 2x to 4x the power in half the space of the previous generation of JBL Synthesis amplifiers.

Bridgeable Channel Pairs

Unlike amps from other manufacturers, the SDA 4600 channels are bridgeable which means even more adaptability for higher power applications such as subwoofers and high power main speakers.

Remote On/Off Interface and Auto Standby

Saves power by integrating the amplifier into a control system so you can easily turn it on and off through the contact closure AUX port. Each channel also has its own auto-standby power so only the channels being used are active. This further reduces wasteful "zombie" power draw and excess standby heat and maximizes the Harman GreenEdge™ design.

Efficient Cooling Design

Highly efficient internal cooling fans provide airflow to the most heat-generating parts. Incorporating the fans into the amplifier brick design maximizes cooling while minimizing wasted energy and noise. This design also eliminates the need to have cooling vent spacers in the rack, further reducing the space needed in ever more compact and fully loaded rack rooms.

Advanced Power Factor Correction (PFC) Universal Power Supply

The most advanced power supply in an installation amplifier delivers power more efficiently in almost any condition than any other amplifier, resulting in less power dissipated and less heat in your racks.

Network Monitoring & Control

Better monitoring, control, and audio manipulation with the HiQnet™ protocol over standard TCP/IP. Remotely see how all networked SDA 4600 amplifiers are performing and control them as needed. In addition, this allows Harman HiQnet™ Audio Architect and "Powered By Crown" iOS® app software tools to work with the SDA 4600 amplifier.

Packed With Extras

Digital Signal Processing including LevelMAX™ Limiters, Input/Output, Delay, Matrix Mixer, Speaker Line Monitoring, 70 Volt or 100 Volt capable outputs give these amplifiers options and features not found on any comparable high-performance amplifier. These features can be used by advanced programmers now and will be utilized for premier whole house and high-powered outdoor audio solutions. SDA amplifiers are the building blocks that will be used for years to come.
