4 Advanced Features

and Options

SST-SBSC (Summed Bass Stereo

Crossover) Module

See Figure 4.1. Features include:

• Stereo biamp.

• Ten user-specified crossover frequencies.

• 12-, 18- and 24-dB/octave (Linkwitz-Riley) filters.

• CD horn equalization.

• Mono summing of sub-bass output for driving subs.

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 4.2. 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-1 amplifier input, and high-frequency signals are routed to the channel-2 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.

Renowned for their durability and efficiency, the CE Series combines advanced technology with user-friendly features to appeal to both professional audio engineers and casual users.

One of the standout characteristics of the CE Series is its robust construction. Built to withstand the rigors of live events and handling, these amplifiers are housed in a rugged chassis that ensures long-term durability. The fan cooling system is designed for efficient thermal management, keeping the amplifier cool even during extended use, which is crucial for maintaining optimal performance.

The CE Series boasts a range of power options, making it versatile for different setups. With models delivering from 1500W to over 4000W per channel, users can choose the appropriate amplifier to match their specific requirements. This flexibility allows the CE Series to support a wide array of speakers and systems, whether for small venues or large-scale arenas.

Crown utilizes innovative technologies in the CE Series amplifiers. One of the key features is the DSP (Digital Signal Processing), which enhances sound quality and allows for precise control over the audio output. The onboard DSP includes presets for various speaker configurations, EQ settings, and time alignment features, facilitating quick adjustments to achieve the desired sound quality.

Another notable feature is the built-in limiters, which protect both the amplifier and speakers from damage due to overload or clipping. This protection ensures reliability during high-pressure situations, such as concerts or events where audio levels can fluctuate dramatically.

Connectivity options in the CE Series are also comprehensive. The amplifiers come equipped with both analog and digital inputs, allowing compatibility with a wide range of audio sources. Additionally, the rear panel includes speakON® outputs for quick and secure speaker connections.

With its combination of power, reliability, and advanced technology, Crown Audio’s CE Series amplifiers stand out in the crowded field of professional audio equipment. These features make the CE Series an excellent choice for audio professionals seeking quality performance across various applications. Whether for a permanent installation or a touring setup, the CE Series amplifiers deliver the sound, durability, and versatility required by today’s audio engineers.
