1. 1/4” inputs from power amp output (full range input only).

2. Speakon™ input from power amp (full range or biamp).

Note: the Speakon pin configuration for biamping is:

1+ LF Positive / 1- LF Negative

2+ MF/HF Positive / 2- MF/HF Negative

3. Full Range/Biamp mode switch

4. Speakon™ through wired in parallel with input Speakon™.

5. 1/4” through wired in parallel with 1/4” input.

MULTI-WAY CROSSOVER CONNECTIONS

(non-powered speakers) Use

either 1/4” or Speakon™ cables for connecting to the power amp and daisy chaining

to an additional speaker.

For high powered and biamp applications, use Speakon™ cables

only.

SUGGESTIONS FOR OPTIMAL PERFORMANCE

• To help control feedback and to correct for venue characteristics, use a graphic EQ.

• For optimal coverage and dispersion, elevate high frequency horn above eye level.

• For optimal headroom, select an amplifier with a power capacity equal to or up to double the

rated program power capacity of the loudspeaker system.

• Ensure all amplifiers are supplied and connected to properly rated AC power circuits.

Underpowering amplifiers may cause premature clipping distortion.

SPEAKER CABLES

Use either Carvin’s PRO50S speaker cable for up to 50’ or high-

current 12GA Speakon™ cables for lengths up to 150’.

18GA cables are not recomended.

You can DAISY-CHAIN up to one additional speaker per cable by using the OUTPUT

connector.

Be sure the total impedance to the amplifier is not lower than the amplifier’s

minimum impedance.

1. 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. 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 compensate 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 operating 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.

8. CROSSOVER BYPASS SWITCH

The crossover bypass switch bypasses the

internal active crossover allowing the use of an outboard active crossover.

9. HI PASS OUTPUT SWITCH

The hi pass output switch changed the output of

the XLR thru output from a parallel of the Input XLR to a hi pass (all frequencies above)

the crossover switch setting.

This is good for going to a top cabinet that can not handle

the sub’s low frequencies.

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-

plifiers are perfectly mated with—the

LSx1502A, LSx1503A

, and

LSx1523A

—creat-

ing optimally 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
