4 Advanced Features

and Options

SST-SBSC-3632T

This is a custom three-channel crossover net- work with CD-horn equalization and summed low-frequency output specifically designed for use with JBL® model 3632T ScreenArray® cinema speaker systems installed in cinemas, studio production and post-production envi- ronments.

Features:

•High-frequency signals are internally routed to the channel-one amplifier input, and mid-frequency signals are routed to the channel-two amplifier input.

•Mono summing of low-frequency signals are routed from Output B to an external amplifier.

•Neutrik® Combo jacks for balanced input connection.

•Removable barrier block connectors for balanced output to other components.

SST-SBSC 4632T

Like the SST-SBSC 3632T but for the JBL 4632T cinema speakers.

SST-4622

See Figure 4.1. This is a custom two-channel crossover network with equalization specifically designed for use with JBL® model 4622 ScreenArray® cinema speaker systems installed in cinemas, studio production and post-production environments.

Features include:

•Low-frequency signals are internally routed to the channel-one amplifier input, and high-frequency signals are routed to the channel-two amplifier input.

•Barrier block connectors for balanced sig- nal input.

SST-3632

Like the SST-4622 but for the JBL 3632 cinema speaker systems.

Additional features include:

•Time correction via an all-pass analog delay ensures coherent summation through the crossover region, while main- taining optimal vertical polar response.

SST-4632

Like the SST-3632 but for the JBL 4632 cinema speaker systems.
