Product Information

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.

Digital Inputs with Analog Backup

With digital audio transport via Harman's proprietary BLU-Link, plus balanced analog inputs, the SDA 4600 gives you tremendous audio advantage with much greater efficiency. The digital link from the amplifier 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.

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 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.

Efficiency 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 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 and 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.
