SYNERGY ARRAY SERIES POWERED SUB.
The dual 21" Yorkville Sound SA221S is a professional, powered portable PA subwoofer from the Synergy Array Series system and is designed to be used as a dedicated subwoofer for the SA153 full-range top or used in conjunction with the SA153 full-range speaker and the SA315S powered subwoofer to create a scalable point-source sound system well suited for professional sound reinforcement companies, rental houses, touring bands, musicians, festivals, concerts, mobile DJs, and other sound providers.
Yorkville has invested a lot of time and research into developing and building their own amplifiers, customizing other raw speaker manufacture products, and using sophisticated DSP to optimize performance/protection, resulting in remarkable peak power transients. The SA221S has visceral and punchy transients followed by a massive, enveloping sustained bass tone, making it a great addition to any setup, especially for bass-oriented events.
The rear panel provides a simplified set of controls for integrating the subwoofer into any environment. A switch for the high-pass filter offers a 50 or 100 Hz for use with the SA315S subwoofer or the SA135 full-range speaker respectively. There are indicator LEDs for power, activity, input clip, X-Max limiting, and VC-Limiting. The integrated DSP provides processing to prevent over-excursion (X-Max), voice coil overheating (VC thermal) and clipping. With the use of IIR filters for crossover and equalization, the Synergy system provides clean and accurate audio reproduction.
A small delay is added to time align with the SA153 top box, while the X-Max limiter and the VC thermal limiter are both frequency sensitive and calibrated to match the characteristics of the driver and cabinet system. The Sub Level control knob attenuates or boosts the subwoofer's output, while a dedicated Average Power Limit knob (100%, 75%, and 50%) can be advanced to limit the power draw in cases where there is less than ample power available. This is a huge benefit for touring and mobile applications, where the available power changes from night to night. By limiting the average power, you can ensure that you won't trip that 15-amp breaker that happens to be sharing power with the ice machine.
The SA221S has a single XLR input with two parallel XLR outputs for connecting a SA153 speaker or additional SA221S subwoofers. Up to 20 subwoofers/tops can be daisy-chained without signal loss (with balanced cables). The rugged enclosure is made from 15mm Birch plywood with a tough speaker paint coating. Two stand adapters are available on top or on the side of the subwoofer. Rubber feet and cups are also on the side and bottom to ensure stability when stacking. Four locking swivel casters are on the rear of the cabinet for ease in transportation. A power cable is included.
