Synergy SA221S Powered Speaker
Thank you for choosing Yorkville’s Synergy SA221S 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 SA221S is constructed of high strength multiply birch plywood for ultimate durability. There are 2 woofers, each 21-inch long-throw.

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 and there is a small delay added to time align with the SA153 top box. 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 VC thermal limiter can be advanced to limit the power draw in cases where there is less than ample power available. The X-Max limiter is faster, pretty much instantaneous. The VC thermal limiter is slower reacting, typically operating near the end of a bass beat at 120 bpm.
The amplifier is a high headroom Class-D design. There is a large capacitor bank so that bass transients are less dependent on the quality of the power line.
The limiter indicators indicate when the X-max or VC thermal limiters are active. Typically, the X-max limiter is more active but this is content dependent. The effect of the line power advance can be observed by carefully watching these limit lights as the control is changed while operating in limit. The VC thermal indicator will come on sooner as the Average Power limiter is advanced. With many types of music, the effect of the VC-therm limiter will be minimal.

1. Power Switch and Indicator
   The green power LED illuminates when the power switch is turned to the On position and AC voltage is supplied. When the power is removed or the power switched is moved to the off position the green power indicator will blink while the power supply is discharging. The processing circuitry will not reboot unless the power supply is fully discharged before being turned back on. It is not necessary to reboot however. Turning the power back on before the power supply is discharged will simply resume normal operation.

2. PowerCON TRUE AC Loop Thru
   The SA221S is equipped with a powerCON TRUE inlet-outlet mains connector. The powerCON outlet at the rear of the SA221S can power another Synergy cabinet. A special power cable accessory called SACABLELOOP is required for this AC loop thru connection. Call your local Yorkville dealer about this accessory.
   IMPORTANT: DO NOT OVERLOAD THE AC MAINS SUPPLY BY CONNECTING TOO MANY CABINETS ON ONE CIRCUIT! PLEASE Read “LINE CURRENT LIMIT CONTROL” and “CASCADE INSTALLATION” IN THIS MANUAL FOR TECHNICAL GUIDANCE.

3. Input Jack
   This female XLR accepts line level XLR microphone cables. For best noise reduction use balanced sources.

4. Dual Link Outputs
   These XLR male connectors can be used with a standard XLR cable to daisy- chain up to 20 SA221S cabinets without signal degradation. Simply loop from one cabinet’s Link jack to the next cabinets Input jack. In many cases this limit of 20 cabinets can be exceeded, consult Yorkville Sound for more details.

5. SA221S Level Control This control adjusts the volume level of the SA221S relative to the input signal level. Mixers and other audio sources connected to the SA221S tend to have different output voltages, which mean the level control on the SA221S is used to fine tune the cabinet’s volume relative to the mixer settings. It is perfectly acceptable to set the SA221S Level above or below the center 0 dB setting.

6. Clip, X-Max, VC-Therm, Activity Indicators
   The Clip and Limit LED indicators illuminate to guide the user to proper operating levels.
   Illumination either of the yellow Limit LEDs indicates that a level has been reached where the SA221S limiters are reducing the signal internally to prevent damage or distortion. It also indicates that further increases in input level or increasing the SA221S Level control position will not appreciably increase acoustic output.
   The red Clip LED indicates that the input level is excessive and further increases in level will cause severe distortion. The input signal should be reduced at the source until Clip activity ceases. The clip indicator comes on at 12 Vrms,16 volts peak. The input clips at 17 Vrms, 24 volts peak. The activity Indicator comes on at 5 mVrms or -45 dBV.

7. Line Current Limit Control
   The SA221S can operate on 15 amp 120 VAC power sources or 20 amp 120 VAC power sources. The SA221SCE operates on a 16 amp 230 VAC power source. Safety regulations limit the power draw on these circuits to 80% of 20, 16 or 15 amps. The SA221S operates within these limitations. The stock product limits the current to 12 amps and when modified by a qualified technician using the SA221SKIT will increase the limit current to 16 amps. Operation when set to 16 amps requires the appropriate power cord and 20 amp power source.
   The average power limit control allows the power to be reduced to allow operation on limited power availability. Full power transients will be allowed through but if the average power is excessive then the power will be limited. This control works by advancing the limiter that limits the voice coil temperature and by monitoring the current draw. In the 16 amp position (8 amp CE) the average power is limited only by the voice coil temperature. In the 12 amp position (6 amp CE) with most music, the limiter will be only active occasionally depending on the music content. In the 8 amp position (4 amp CE) certain types of music will not be limited, primarily music without deep bass or where the bass is unprocessed.
   The 6 amp position (3 amp CE) will significantly reduce the output when the music content has continuous bass content below 45 Hz. The green power on indicator will dim to indicate when the line current limiter is active. A small amount of dimming indicates that the advanced thermal limiter is active while significant dimming indicates that the line current monitoring system has detected excessive line current. Low line voltage typically due to long power supply cables may cause excessive line current, the line current monitoring system will prevent this from tripping the power source circuit breakers.

8. 50 Hz High-Pass Output
   The SA221S provides a line level 50 Hz high-pass XLR output intended to provide the correct equalization, crossover and time alignment to use SA315S subwoofers along with SA221S subwoofers. This output is not suitable for any other usage. This output should not be routed to the full range cabinets. Normally this would be used with the 50 Hz lowpass switch depressed.

9. 100 Hz /50 Hz Lowpass Switch
   This switch allows the SA221S subwoofers to be used with SA315S subwoofers. Combined with the 50 Hz Highpass output this will ensure correct crossover and time alignment.

ELECTRICAL SAFETY
It is always important to connect all sound reinforcement equipment to ac mains supply circuits that have proper electrical safety grounds. Never break off the Earth Ground pin from a 3-prong plug. This pin provides personal protection from electrical shock and protection of the equipment from lightning strikes and electrostatic buildup. It is also required for EMC shielding. Replace the plug if the Earth Ground pin is missing.

1. Always connect the equipment to a circuit with a suitable electrical ground.
2. Do not overload the power cords and convenience outlets.
3. Always inspect the cords and plugs before use. Do not use outlets or cords that have exposed conductors, are worn or damaged. Replace electrical cords that have worn or damaged insulation and remember to pull the plug not the cord to prevent damage to the cord. Only replace with the equivalent heavy-duty cord supplied by the manufacturer.
4. The AC supply cord should be routed so that it is unlikely that it will be damaged. Protect the power cord from being walked on or pinched. If the AC supply cord is damaged DO NOT OPERATE THE UNIT. To completely disconnect this apparatus from the AC Mains, disconnect the power supply cord plug from the AC receptacle. The mains plug of the power supply cord shall remain readily accessible. Unplug the apparatus during lightning storms or when unused for long periods of time. Route cords away from traffic to avoid tripping hazards and unnecessary wear on the power cord.
5. Never Break Off the Third Prong on a Plug. Replace broken 3-prong plugs and make sure the third prong is properly grounded.
6. Keep line cords away from heat, water and oil. They can damage the insulation and create a shock hazard.
7. Do not tie cords in tight knots. Knots can cause short circuits and shocks. Loop the cords or use a twist lock plug.
