Instructions pertaining to a risk of fire, electric shock, or injury to a person
CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER (OR BACK).
NO USER SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL. THIS DEVICE IS FOR INDOOR USE ONLY!
INSTALLED BATTERY PACKS SHALL NOT BE EXPOSED TO EXCESSIVE HEAT SUCH AS SUNSHINE, FIRE OR THE LIKE.
Read Instructions: The Owner’s Manual should be read and understood before operation of your unit. Please, save these instructions for future reference and heed all warnings.
Cleaning: Clean only with dry cloth.
Packaging: Keep the box and packaging materials, in case the unit needs to be returned for service.
Warning: To reduce the risk or fire or electric shock, do not expose this apparatus to rain or moisture. Do not use this apparatus near water!
Warning: When using electric products, basic precautions should always be followed, including the following:
Power Sources
Your unit should be connected to a power source only of the voltage specified in the owners manual or as marked on the unit. This unit has a polarized plug. Do not use with an extension cord or receptacle unless the plug can be fully inserted. Precautions should be taken so that the grounding scheme on the unit is not defeated. An apparatus with CLASS I construction shall be connected to a Mains socket outlet with a protective earthing connection. Where the MAINS plug or an appliance coupler is used as the disconnect device, the disconnect device shall remain readily operable.
Hazards
Do not place this product on an unstable cart, stand, tripod, bracket or table. The product may fall, causing serious personal injury and serious damage to the product. Use only with cart, stand, tripod, bracket, or table recommended by the manufacturer or sold with the product. Follow the manufacturer’s instructions when installing the product and use mounting accessories recommended by the manufacturer. Only use attachments/accessories specified by the manufacturer.
Equipment that is suspended overhead must use a secondary safeguard to prevent personal injury in the event the primary mounting mechanism fails. Safety eyebolts attached to the equipment and galvanized steel wire can be used together to implement a failsafe mounting thus ensuring the safety of the equipment and anyone positioned below the equipment.
Improper installation can result in bodily injury or death. If you are not qualified to attempt the installation get help from a professional structural rigger.
Note: Prolonged use of headphones at a high volume may cause health damage to your ears.
The apparatus should not be exposed to dripping or splashing water; no objects filled with liquids should be placed on the apparatus.
Te rminals marked with the “lightning bolt” are hazardous live; the external wiring connected to these terminals require installation by an instructed person or the use of ready made leads or cords.
Ensure that proper ventilation is provided around the appliance. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.
No naked flame sources, such as lighted candles, should be placed on the apparatus.
Power Cord
Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. 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 particularly at plugs. 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 operable.
Unplug this apparatus during lightning storms or when unused for long periods of time.
Service**
The unit should be serviced only by qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, requires battery  pack replacement or has been dropped. Disconnect power before servicing!

CAUTION
TO PREVENT ELECTRIC SHOCK HAZARD, DO NOT CONNECT TO MAINS POWER SUPPLY WHILE GRILLE IS REMOVED. PSA1s Introduction
Congratulations on your purchase of the PSA1s. The PSA1s is a premium-quality integrated subwoofer and
power amplifier. It has been designed to be the perfect complement to our Paraline Series PSA1 powered
speaker.

1. Input Level Switch
   The Input level switch is provided to choose between line-level and speaker- level signals. The line-level position is for use when the PSA1s is fed a signal from a processor, electronic crossover, the output of an un-powered mixer, or the loop-through of a powered speaker cabinet. When using the line- level mode, the use of balanced ¼-inch (Tip, Ring, Sleeve) and/or XLR cables will reduce the unit’s sensitivity to hum and buzz.
   The speaker level position should be used when the PSA1s is fed with a ¼-inch speaker cable from the output of an amplifier or a powered-mixer, or from the parallel connection on an un-powered speaker cabinet. Fospeaker level operation, connect the PSA1s just like an ordinary speaker (in parallel using the loop-through jacks)along with the passive full-range loudspeakers.

2. PSA1s Level Control
   The Level control adjusts the amount of bass added to the sound system by the PSA1s. This control adjusts for the relative sensitivity of the companion full-range loudspeakers and the desired system frequency response. This control should be set by listening with a medium-level input signal (such that the limiter is not firing). Note : It is not recommended to set this control at high levels since the limiter determines the output level.
   Note: A setting at the center detent on the PSA1s Level control is the correct starting point when setting up a sound system. From there, adjustments can be made for the best sound. The detent is the setting that will give full power when the line input is used and the input signal is at a level of +3 dBV.

3. Input Jacks
   The inputs are designed to make it easy to hook up your PSA1s to almost any audio system with minimal hassle. Both ¼-inch and XLR inputs and Thru connections are supplied.
   The PSA1s may be plugged in before or after the full-range loudspeaker. The PSA1s does not alter the signal to the daisy-chained (thru) loudspeakers and will not draw any power from the host amplifier/processor  driving them. Also, note that an external crossover is not necessary when using the PSA1s.
   Note: As well as accommodating full-range loudspeakers, the Thru jacks allow many PSA1s subwoofers to be connected in a string (parallel). There is no practical limit to the number of PSA1s subwoofers that may be connected together.

4. Protection
   The PSA1s has several internal protection mechanisms against over-current, over-excursion, clipping, and excessive average power output. In some cases, when protection is activated, the output will be cut off. In these cases, the power LED will blink, and the PSA1s will attempt to restart itself. If the fault persists, you should take your PSA1s to the nearest authorized service center for repair by a qualified service technician.
   ** At high power levels when the limiter is operating, increasing the subwoofer level control will not increase the output. For the best results, set the system so that the limiter LED occasionally (a few times per second) lights up. The limiter is present in the circuit at all times to prevent distortion and to prevent over-excursion of the speakers.
   Note: The PSA1s’ built-in stand mounting adapter can be used with the Yorkville SW-TUBEHD accessory to support either one or two of our PSA1 cabinets. The support tube can be used safely as long as the PSA1s is on a flat, level surface.
   WARNING:** Larger or heavier cabinets should NOT be used!
