Synergy SA315S Powered Speaker

Thank you for choosing Yorkville's Synergy SA315S subwoofer, the companion subwoofer to the SA153. The SA series excels in sound reinforcement applications where a line array is desired but cannot be easily accommodated.

Cabinet Features

The SA315S is constructed of high strength multiply birch plywood for ultimate durability. It features 3 woofers, each 15-inch-long-throw. The design allows the SA315S to match the footprint of the SA153 top cabinets.

Electronic Features

A Yorkville proprietary DSP platform provides processing to prevent over-excursion (X-Max), voice coil overheating (VC thermal), and clipping. The DSP uses IIR filters for crossover and equalization, with a small delay added to time align with the SA153 top box. The X-Max limiter and VC thermal limiter are frequency sensitive and calibrated to the driver and cabinet system. The VC-thermal limiter can be advanced to limit power draw when power is limited. The X-Max limiter is faster (near instantaneous), while the VC-thermal limiter reacts slower, typically operating near the end of a bass beat at 120 bpm. The amplifier is a high headroom Class-D design with a large capacitor bank, making bass transients less dependent on power line quality. Limiter indicators (Clip, Limit, X-Max, VC-Therm) show when limiters are active. The Clip LED indicates excessive input level, while Limit LEDs indicate signal reduction by internal limiters.

Key Features and Controls

1. Power Switch and Indicator

The green power LED illuminates when the power switch is ON and AC voltage is supplied. The indicator blinks while the power supply discharges after power is removed or the switch is turned OFF. The processing circuitry will not reboot unless the power supply is fully discharged before being turned back on. Turning the power back on before full discharge will resume normal operation.

2. PowerCON TRUE AC Loop Thru

The AC inlet accepts locking PowerCON TRUE power cords. An AC outlet allows looping power to other cabinets using a male-to-female PowerCON TRUE looping power cord. IMPORTANT: DO NOT EXCEED THE CURRENT RATING OF THE POWER AND ACCESSORY CORDS. Refer to the CASCADE INSTALLATION section of this manual.

3. Input Jack

This female-XLR accepts line level XLR microphone cables. Use balanced sources for best noise reduction.

4. Dual Link Outputs

These XLR male connectors allow daisy-chaining up to 20 SA315S cabinets via standard XLR cables without signal degradation. Connect one cabinet's Link jack to the next cabinet's Input jack. The limit of 20 cabinets may be exceeded in many cases; consult Yorkville Sound for details.

5. SA315S Level Control

This control adjusts the SA315S volume relative to the input signal level. It fine-tunes the cabinet's volume based on mixer settings. Setting the Level control above or below the center 0 dB is acceptable. NOTE: With level controls at "0," limiting begins at +4 dBV, varying with signal content.

6. Clip, X-Max, VC-Therm, Activity Indicators

Clip and Limit LED indicators guide users to proper operating levels. Yellow Limit LEDs indicate signal reduction by limiters to prevent damage or distortion, and that further input increases won't significantly increase acoustic output. The red Clip LED indicates excessive input level causing severe distortion; reduce input signal at the source. Clip indicator illuminates at 12 Vrms / 16 volts peak; input clips at 17 Vrms / 24 volts peak. Activity indicator illuminates at 5 mVrms or -45 dBV.

7. Average Power Limit Control

This control reduces power for operation with limited power availability. Full power transients are allowed, but excessive average power is limited. This control advances a limiter that manages voice coil temperature. At 100%, power is limited only by voice coil temperature. At 75%, music with deep continuous bass is limited. At 50%, only music without deep bass or unprocessed bass is limited; voice applications are typically not limited.

RATED CURRENT

a The LINE CURRENT LIMIT SWITCH allows the user to limit the maximum continuous current consumption to reduced values as shown.

Electrical Safety:

• Always connect equipment to circuits with proper electrical safety grounds. Never break off the Earth Ground pin from a 3-prong plug.
• Do not overload power cords and outlets.
• Inspect cords and plugs before use. Replace worn or damaged cords. Pull the plug, not the cord, to disconnect.
• Route AC supply cords to prevent damage. Protect from being walked on or pinched. If damaged, DO NOT OPERATE.
• To disconnect from AC mains, pull the plug from the receptacle. The mains plug must remain readily accessible.
• Unplug during lightning storms or long periods of inactivity. Route cords away from traffic.
• Never break off the third prong on a plug. Replace broken 3-prong plugs and ensure proper grounding.
• Keep line cords away from heat, water, and oil.
• Do not tie cords in tight knots; use loops or twist-lock plugs.

Bumper Mounting

IMPORTANT: Rigging of loudspeaker systems is a serious matter requiring extensive experience in load limits, hardware installation, and safety inspection. If unqualified, use a professional structural rigger. Improper installation can result in injury or death. Consult a structural engineer for building load calculations.

Steps for Bumper Mounting:

1. Remove the [PIN] from Box 1 (Figure 1).
2. Remove the [LOCK BAR] from the rail (Figure 2).
3. Stack Box 2 on top of Box 1.
4. Line up the feet of Box 2 with the recess in Box 1 (Figures 3, 4, and 5).
5. Insert the [LOCK BAR] into the rails of Box 1 and Box 2 (Figure 6).
6. Insert the [PIN] to secure the Lock Bar (Figures 7 and 8).
7. Line up boxes as shown (Figure 9), then set up the Bumper as shown (Figures 10 and 11).
8. Insert the [LOCK BAR] into the rails of the BUMPER and BOX ASSEMBLY (Figure 12).
9. Insert the [PIN] to secure the Lock Bar (Figure 13).
10. The LOCK BAR and PIN are now installed (Figures 14 and 15).

SABUMPER1 Users Guide

Important Safety Considerations:

• Experienced professionals should only carry out rigging.
• Use mounting and rigging hardware rated to meet or exceed the weight being hung.
• Inspect mounting and rigging hardware regularly; replace worn or damaged components immediately.

The SABUMPER1 is designed to hang arrays of SA153 and SA315S Synergy Series Loudspeakers. Up to 4 columns wide and 3 cabinets deep (max 12 cabinets) can be safely hung at a 7:1 safety rating.

SA153 and SA315S cabinets can be flown right side up or upside down by engaging the [LOCKBAR] into the [RAILS] on the underside of the SABUMPER1 and securing with the [quick pin]. When flying cabinets above/below each other, they should be mirrored for optimal performance.

The SABUMPER1 has 4 main hanging rails for motor hoists. A minimum of 2 pick-up points are suggested, located on either the inner or outer hanging rails, regardless of cabinet placement.

Two extension tilt bars are provided for array tilt. Pick-up points can be moved forward or rearward. Slide extension bars into main hanging rails and secure with a 5/8-inch shackle (shackles not included).

Hanging an Array:

1. Attach main pick-up points from the motor hoist to the SABUMPER1. Raise the bumper enough to roll the first row of cabinets underneath.
2. Cluster the first row of cabinets tightly together below the bumper. Slowly lower the bumper onto the cabinets, aligning the [RAILS] on the bumper's underside with the [RAILS] on the top of each cabinet.
3. Remove [quick pins] and [LOCKBARS] from dollies and cabinets. Insert the [LOCKBAR] into the [RAILS] on the bumper's underside and the top of each cabinet. REMEMBER TO REPLACE EACH QUICK PIN TO SECURE THE LOCKBARS. FAILURE TO DO SO COULD RESULT IN THE LOCKBARS SLIDING OUT DURING USE.
4. Once LOCKBARS and quick pins are secure, raise the bumper and roll dollies away.
5. Roll the next row of cabinets into place and repeat the process, lowering cabinets onto each other, removing LOCKBARS and quick pins from dollies, and securing them into the RAILS between cabinets.

To dismantle, reverse the process: lower cabinets onto dollies, remove LOCKBAR and quick pins from between cabinets, and secure them into the dollies.

SAPICKUPBAR1

Installation:

1. Remove the 4 bolts securing the [RAIL] to the cabinet and discard. NOTE: The SAPICKUPBAR1 can be installed on the top and/or bottoms of the SA153 and SA315S speaker cabinets.
2. Slide SAPICKUPBAR1 into the [RAIL] and align holes (holes will not align if installed backwards).
3. Secure SAPICKUPBAR1 and [RAIL] to the cabinet with the supplied 4 [BOLTS] and [LOCKING WASHERS].
4. SAPICKUPBAR1 installed.

Included: 1x SAPICKUPBAR1, 4x YS#9400SS Lock Washers, 4x YS#9125 Bolts.
