APS Powered Speakers APS ACTIVE POWERED SYSTEMS Carvin's APS (Active Powered Systems) amplification packs take the guesswork out of selecting the ideal power source to drive your loudspeakers. With bi-amped and tri-amped models designed to handle the most demanding applications, the APS am- APS plifiers are perfectly mated with-the LS1502A, LS1503A, and LS1523A-creating op- timally designed powered loudspeaker systems that are ready for anything you throw at them. There's even one APS power pack created specifically to generate the bone crushing impact of our LS1801A subwoofer. APS-based LS loudspeaker systems make setup and operation easier as well, with less gear to haul. Feed your mixer's output dAirCeTcIVtlEy PtoOtWhEeRseEDloSuYdSsTpEeMakSer systems, and you're ready to rock!

Input/THRU OUTPUT Use the balanced XLR or 1/4" connectors featured on the rear control panel. Using a balanced source will reduce noise which may be picked up by the cable. You may DAISY-CHAIN as many APS systems as you wish. All connectors are wired in parallel. 2. APS EQUALIZATION The APS powered loudspeakers offer a by passable 3-band mid sweep equalizer for custom tuning to the acoustical environment. The EQ system is engineered specifically for the APS, featuring a boost and cut range of ±6dB to prevent radical adjustments that could otherwise compromise the sound of the system. The Mid-band sweep is particularly useful for enhancing critical mid range frequencies for stage monitoring or for cutting certain frequencies to compen- sate for room resonances. Press the "EQ IN" switch to activate the equalizer. The BLUE LED displays when the EQ is active. 3. Level control The LEVEL control adjusts the output volume of the APS. Start by setting the LEVEL at "0". Weak input signals can be boosted by set- ting the LEVEL at "+6". Strong signals can be reduced by turning the LEVEL toward "-12". The RED LED will flash if the internal power amps start to clip. Turn the LEVEL control down to avoid clipping. Damage to the drivers can result from operat- ing at a level where the RED CLIP LED is constantly illuminated. 4. Power/protect/CLIP INDICATOR Power up your audio source first, then turn on the APS with the power switch. When the system is active, the LED will indicate GREEN. When shutting down turn off the APS first, then turn off the mixer. If any of the power amps are clipping, the LED will indicate RED and you should reduce the output level. If the system should go into protect mode, the LED will indicate YELLOW and the power amps will shut off. This may occur if; a) the system is overheated due to clipping the power amps for an extended period of time, b) one of the internal drivers developed a short or c) the power amps require service. 5. Power Push this switch to the UP position to apply power to the unit. The POWER LED will light to show the system is on. 6. AC Power Use a standard grounded AC cord. Whenever possible, use dedicated circuits for powered speakers. The powered speakers are available in either 120V or 240V models. 7. crossover Frequency switch The CROSSOVER FREQUENCY switch selects the crossover point for the APS. The 120Hz out setting is generally used with small to mid sized speakers in your setup. Almost all 12" and 15" woofers will benefit from the 120Hz setting. The 80Hz (switch in) setting is generally used with larger 18" woofers.
