Superb sound with reliability has been one of Carvin’s trademarks for high
performance loudspeakers. High grade components, lightweight Poplar
plywood with dado construction ensures high performance for many years.
For road worthiness, Carvin uses recessed steel handles, steel corners,
expanded metal steel grilles and duratuff™ covering. Front loaded woofers
and wide dispersion titanium high frequency drivers are used to reproduce
the full audio spectrum with superb clarity.
Carvin’s APS™ Active Powered Speakers are more than just another “power
amp in a cabinet”. Biamp or Triamp models feature time aligned circuitry
and adjustable EQ resulting in a much more efficient system that adds clarity to your sound that our competitors do not offer. Every APS™ loudspeak-
er utilizes Carvin’s DCM power amp technology for continuously rated RMS
power. Carvin’s extensive engineering along with numerous listening tests
have proven our “made in USA” loudspeakers to be superior. Like millions
of users around the world, enjoy using your new loudspeaker.
LIMITED WARRANTY
Parts and labor are covered for 1 year on manufacturer’s defects. Warranty does not cover burned out drivers caused by excessive power or distortion, or physical damage caused by general use, moisture or dust.
CAUTION: Square wave distortion from power amps
can destroy drivers much faster than clean RMS
power. The power generated by the APS internal power
amps has the capacity to damage the drivers, in which
case they would not be covered under warranty.

REAR CONNECT PLATE
(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 applications, use Speakon™ cables only.
SUGGESTIONS FOR OPTIMAL PERFORMANCE
To help control feedback, use a graphic equalizer. Keep the speakers in front of the microphone. Never direct
the microphone towards the speaker. For greater coverage, add additional speakers.
Doubling the speakers adds four times the acoustical power which is more advantagious
than increasing power.
SPEAKER CABLES
Use either Carvin’s PH50 speaker cable for up to 50’ or highcurrent 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 amp is not lower than the
amp’s minimum impedance.

APS BI-AMPED/TRI-AMPED LOUDSPEAKERS
Carvin’s APS™
Active Powered Speakers are more than just another “power amp in a cabinet”.
With two separate power amps in the 2-way systems and three separate power
amps in the 3-way systems, a more efficient design adds clarity as each amp only
needs to reproduce frequencies for it’s respective driver. Compared to other powered speakers the APS system will deliver more clarity with greater power.
APS POWER AMPS
APS loudspeakers utilize Carvin’s DCM power amp tech-
nology to supply continuously rated RMS power.
APS TIME ALIGNMENT CIRCUITRY
Due to the physical size and placement of various drivers in a speaker enclosure, the sound of each driver reaches your
ears at different times. This difference is enough to cause a slight phase change. To
alleviate this problem, the APS utilizes time delay circuits to time-align the drivers with
one another.
APS ACTIVE ELECTRONIC CROSSOVERS
An electronic crossover
splits the incoming signal into specific frequency ranges before going to the separate
amps for each driver. For superior frequency control and maximum phase accuracy,
the APS utilizes the design of our XC3000 crossover featuring sharp 4th order
24dB/octave Linkwitz-Riley filters. Perfect crossover points are achieved with appropriate frequencies going to each driver. A subsonic filter improves woofer efficiency
by removing extremely low frequencies under 20 Hz that waist power.
1. INPUT/THRU OUTPUT
Use the balanced XLR or 1/4” connectors fea-
tured 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 pass-
able 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 setting 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.
