REAR PANEL DESCRIPTION
1. MAIN INPUT
This is a female XLR-type connector that accepts a balanced line-level signal from a mixing console or other signal source.

6. AC Receptacle
This is where you connect the AC linecord to provide AC power to the SR1530z's built-in power amplifiers. Plug the linecord into an AC socket properly configured for your particular model.

2. LOOP OUT
This is a male XLR-type connector that produces exactly the same signal that is connected to the MAIN INPUT jack. Use it to daisy-chain several SR1530z's together off the same signal source.

3. Power ON Indicator
When the POWER switch is turned on, and the linecord is connected to an active AC power supply, this indicator lights green to let you know that you're ready to rock and roll. The cool blue LED on the front of the cabinet works in the same way.

4. PROTECTION Indicator
The SR1530z has a built-in limiter that prevents the amplifier outputs from clipping or overdriving the transducers. The PROTECTION indicatior lights when the limiter is activated. It's okay for the PROTECTION indicator to blink occasionally, but if it blinks frequently or lights continuously, turn down the signal source's level control until the PROTECTION indicator only blinks occasionally. There is also a thermal protection circuit that monitors the internal temperature of the amplifiers and heatsink. If the temperature should exceed a safe operating level, this indicator lights and the signal is muted to allow the amplifiers to cool. When the temperature cools to a safe level once again, the thermal protection circuit deactivates and normal operation continues. Note: Activation of the thermal protection circuit is an indication that you should take steps to avoid continued thermal problems. See "Thermal Considerations" on page 6.

DAISY-CHAINING MULTIPLE SR1530z' S

CONNECTIONS
The SR1530z has one female XLR input that accepts a balanced line-level signal. When connecting a balanced signal, be sure it's wired per AES (Audio Engineering Society) standards: XLR Hot (+) Pin 2 Cold (­) Pin 3 Shield (Ground) Pin 1

The LOOP OUT jack is wired straight from the MAIN INPUT connector -- there is no electronic circuitry between -- so the signal coming out of the LOOP OUT jack is exactly the same as the signal going in.

PLACEMENT
The SR1530z speaker is designed to sit on the floor or stage. WARNING: The cabinet has no rigging points and is not suitable for rigging. NEVER attempt to suspend the SR1530z by its handles. The SR1530z should never be pole-mounted. You can create a horizontal array by placing the cabinets side-by-side. However, you should have a good understanding of the relationship between the splay angle (the angle between the facing sides of the cabinets), the on-axis power, and frequency cancellation effects between cabinets. When two cabinets are placed side-by-side, the actual splay angle is 20º (determined by a 10º angle on each cabinet side). As the splay angle increases toward the angle of horizontal coverage (90º for the SR1530z), the on-axis power decreases, but the frequency response becomes smoother as the comb-filtering effects (caused by the interaction in the area of double-coverage) decrease. As with any powered components, protect them from moisture. If you are setting them up outdoors, make sure they are
under cover if you expect rain.

Balanced XLR Connectors

There is also a male XLR connector labeled LOOP OUT. This is also wired according to the above AES standard. The LOOP OUT connector allows you to connect more than one SR1530z to your system. Simply plug the signal source (i.e., mixer output) into the first MAIN INPUT jack, and patch that speaker's LOOP OUT jack to the next MAIN INPUT jack, and so on, daisy-chaining multiple speakers.

Room Acoustics
The SR1530z loudspeakers are designed to sound as neutral as possible; that is, to reproduce the input signal as accurately as possible. Room acoustics play a crucial role in the overall performance of a sound system. Here are some additional placement tips to help overcome some typical room problems that might arise: · Avoid placing loudspeakers in the corners of a room. This increases the low frequency output and can cause the sound to be muddy and indistinct. Avoid placing loudspeakers against a wall. This, too, increases the low frequency output, though not as much as corner placement. However, if you do need to reinforce the low frequencies, this is a good way to do it. Avoid placing the speakers directly on a hollow stage floor. A hollow stage can resonate at certain frequencies, causing peaks and dips in the frequency response of the room. It's better to place the loudspeakers on a sturdy table or stand designed to handle the weight of the SR1530z. Position the loudspeakers so the high-frequency drive
rs are 2 to 4 feet above ear level for the audience (make allowances for a standing/dancing in the aisles audience). High frequencies are highly directional and tend to be absorbed much easier than lower frequencies. By providing direct line-of-sight from the loudspeakers to the audience, you increase the overall brightness and intelligibility of the sound system. Highly reverberant rooms, like many gymnasiums and auditoriums, are a nightmare for sound system intelligibility. Multiple reflections off the hard walls, ceiling, and floor play havoc with the sound. Depending on the situation, you may be able to take some steps to minimize the reflections, such as putting carpeting on the floors, closing draperies to cover large glass windows, or hanging tapestries or other materials on the walls to absorb some of the sound. However, in most cases, these remedies are not possible or practical. So what do you do? Making the sound system louder generally doesn't work because the reflections become louder, too. The
best approach is to provide as much direct sound coverage to the audience as possible. The farther away you are from the speaker, the more prominent will be the reflected sound. Use more speakers strategically placed so they are closer to the back of the audience. If the distance between the front and back speakers is more than about 100 feet, you should use a delay processor to time-align the sound. (Since sound travels about 1 foot per millisecond, it takes about 1/10 of a second to travel 100 feet.) 6

THERMAL CONSIDERATIONS
The SR1530z has three powerful built-in amplifiers capable of producing a combined 500 watts of power. As amplifiers produce heat, it is important to dissipate the heat as quickly as possible. This results in increased reliability and longevity for the amplifier. The amplifier module is mounted on a large heatsink, which is cooled by convection where cool air is drawn through it's fins, carrying the heat away. In order for this convection cooling to work efficiently, it is important to provide adequate airspace behind the loudspeaker. When you position the SR1530z, we recommend leaving at least six inches of air space behind it. In the unlikely event of the amplifier overheating, a built-in thermal switch will activate, which mutes the signal. When the amplifier has cooled down to a safe operating temperature, the thermal switch resets itself, and the SR1530z resumes normal operation. If the thermal switch activates frequently, try turning down the level control a notch or two on the mixing console (or the b
ack of the SR1530z) to avoid overheating the amplifier. If the temperature in the room is too high, it could cause the amplifier to overheat. In this case, you should try aiming a fan at the rear panel to move more air through the heatsink fins.

AC POWER
Be sure the SR1530z is plugged into an outlet that is able to supply the correct voltage specified for your model. If the voltage should drop below 97% of the specified line voltage, the built-in amplifiers will no longer be able to supply rated power. (They will continue to operate down to 80% of the rated line voltage, but won't reach full power, resulting in lower headroom.) Be sure the electrical service can supply enough amperage for all the components connected to it. We recommend that a stiff (robust) supply of AC power be used because the amplifiers place high current demands on the AC line. The more power that is available on the line, the louder the speakers will play and the more peak output power will be available for cleaner, punchier bass. A suspected problem of "poor bass performance" is often caused by a weak AC supply to the amplifiers. Never remove the ground pin on the power cord of the SR1530z or any other component. This is very dangerous.
