Dolby SYS50 – SLS Screen Channel Speaker System

What is the Dolby SLS SYS50?

The SLS System 50 is a full-range, passive screen channel cinema speaker system for small auditoriums, made up of one SLS CS50. Its high-frequency section uses the PRD500 planar ribbon transducer designed and manufactured by SLS Audio, paired with a 12-inch woofer. The front-ported enclosure extends bass to 40 Hz and is well suited to theaters of 50 to 75 seats.

How does the Dolby SLS SYS50 work?

A passive crossover divides the signal between the 12-inch low-frequency driver and the PRD500 ribbon, so each System 50 runs from a single amplifier channel at 8 ohms. The planar ribbon gives fast transient accuracy and a smooth high-frequency response, and it keeps more direct sound reaching the audience even with screen spreading.

Coverage is 90° horizontal by 40° vertical (-6 dB, excluding screen scattering). Sensitivity is 99 dB, power handling is 120 W (31 V) AES/2, and calculated output reaches 120 dB continuous and 126 dB peak at one metre. The 13-ply 3/4-inch Baltic birch cabinet has a flat black latex finish, and an included U-bracket makes installation and aiming straightforward.

Three System 50 units typically form the left, center and right screen channels. Drive them from a Dolby processor such as the CP950 or CP950A through a Dolby Multichannel Amplifier such as the DMA16302, using Dolby's published SYS50 processor settings.

Frequently Asked Questions

What is the difference between the SYS50 and the CS50?

Dolby defines System 50 as one CS50, so the hardware and specifications match. Ordering by system makes it easy to quote a complete LCR set.

Is it compatible with Dolby cinema processors?

Yes. It is a passive 8-ohm speaker driven through amplifier channels from Dolby processors such as the CP950 or CP950A, using Dolby's published settings.

What size room is it for?

Dolby recommends System 50 for small theaters with 50 to 75 seats.

Can it be upgraded for more bass?

Yes. Adding an SLS CSB115 low-frequency module and bi-amplification turns the CS50 into the System 100A.

What warranty and support are available?

System 50 carries Dolby's manufacturer warranty, confirmed with your quote. Creation Networks designs, installs and tunes Dolby cinema systems; see the Dolby Professional collection and request a quote.
