Cinema SA4 DSi SA4 4-Channel Professional Cinema Amplifier, US Version
The Cinema SA4 DSi SA4 is a compact yet powerful professional cinema amplifier built on proven Crown DSI Digital Screen Array technology. Its 2RU footprint delivers serious amplification muscle in a footprint that fits standard rack installations, making it ideal for cinema, theatrical, and commercial audio environments where space and reliability are both critical.
Digital Processing & Audio Architecture
This amplifier operates on 96kHz/32-bit floating-point processing with integrated FIR filtering, LevelMAX limiting, and 8-channel parametric EQ to shape the signal at the amplifier stage. The onboard delay capability provides critical timing alignment for distributed speaker systems, eliminating phase issues across multiple zones.
Power & Connectivity
The SA4 provides four independent channels with bridgeable outputs, capable of handling 2-ohm impedance operation for maximum flexibility in system design. This configuration supports everything from stereo cinema configurations to discrete surround and effects channels in a single compact unit.

Frequently Asked Questions
What makes the DSI Digital Screen Array technology valuable for cinema and theater?
The DSI architecture is purpose-built for cinema and theatrical environments, delivering phase-accurate amplification with integrated delay and EQ to align distributed speaker systems across large rooms and eliminate timing issues across multiple zones.
What DSP tools are built into this amplifier?
The SA4 includes 8-channel parametric EQ, integrated FIR filtering for acoustic correction, onboard delay for phase alignment, and LevelMAX limiting protection on all four channels—all operating at 96kHz/32-bit floating-point resolution.
Can this amplifier handle different speaker impedances and configurations?
Yes. The four channels are bridgeable and support 2-ohm impedance operation, allowing flexible system design from stereo cinema setups to discrete surround and effects channels in a single unit.
What is the physical footprint, and does it fit standard rack installations?
The SA4 is a 2RU compact amplifier designed to fit standard professional rack installations, delivering serious amplification power while conserving valuable rack space in cinema and theatrical facilities.
Is this suitable for home listening or practice applications?
No. This amplifier is engineered exclusively for professional cinema, theatrical, commercial installation, and live performance environments where phase accuracy, low-noise operation, and DSP-integrated amplification are essential.
