Synergy SA153 Powered Speaker
Thank you for choosing Yorkville’s Synergy SA153 arrayable speaker, the pinnacle of clarity and output in a
fully expandable speaker system. The SA153 excels in sound reinforcement applications where high output
and precise control of horizontal dispersion are required. Used alone or in multiples with the matching SA315
subwoofers, the SA153 is designed to deliver reliable, high quality audio at a professional level.
Cabinet Features
The SA153 is constructed of high strength multiply birch plywood for ultimate durability. At the heart of the
SA153 is a Paraline lens loaded with a coaxial compression driver along with a 15-inch woofer mounted on a
22.5°H x 45°V constant directivity horn. Paraline technology was first developed for Yorkville’s flagship VTC
Pro Audio Elevation series line array. By channeling the sound waves along equidistant paths, the Paraline lens
converts the point source compression driver into a line source with constant phase and amplitude. The result
is a completely balanced sound field and coverage pattern across the cabinet’s horizontal and vertical planes.
The unique design of the SA153 allows the cabinets to be placed side by side without interference.
Cabinets can be placed together to cover as wide a pattern as desired, including 360 degrees, without
any lobing or interference patterns.
Electronic Features
Innovative DSP processing is used to drive the 2000-watt Class-D woofer amplifier and the three-tier
300-watt horn amplifiers. An active crossover for the amplifiers ensures that the woofer and horn operate
optimally; meanwhile, separate non-defeatable limiters protect those drivers from excessive peaks and
over-powering. The drivers themselves are sourced from the world’s premier manufacturers offering an
extended lifetime of smooth, powerful performance. We are confident you will find the SA153 a worthy
mainstay for all of your sound application needs.
1. Input Jack
This female-XLR accepts line level XLR microphone cables. For best noise reduction use balanced sources.
2. Dual Link Outputs
These XLR male connectors can be used with a standard XLR cable to daisy-chain up to 20 SA153 or SA315
cabinets without signal degradation. Simply loop from one cabinet’s Link jack to the next cabinets Input jack.
3. SA153 Level Control
This control adjusts the volume level of the SA153 relative to the input signal level. Mixers and other au-
dio sources connected to the SA153 tend to have different output voltages, which mean the level control
on the SA153 is used to fine tune the cabinet’s volume relative to the mixer settings. It is perfectly accept
-
able to set the SA153 Level above or below the center 0 dB setting. When arraying multiple cabinets, it
may be desirable to reduce the volume of some cabinets to better cover the audience. (ex. The outer box
of a cluster may be against a wall)
4. Mode Switch (Sub/No Sub)
This switch allows the user to configure the SA153 to be used with or without a subwoofer. In “No Sub” mode,
the cabinet’s internal high-pass (low-cut) filter is set to 40 Hz. When using the SA153 with a subwoofer, such as
the SA315, depress the button to set the internal high-pass filter to align perfectly with the subwoofer.
