LS Series LOUDSPEAKERS USER MANUAL
The LS Series from Carvin Audio are one of the best
loudspeaker values available, offering superb sound at high
output levels. Your audience will appreciate the crystal clear
highs, high intelligibility in the vocal range and deep solid
bass, making all the difference in your performance. Building
LS112
LS153
upon the company’s long standing reputation for great sonic
performance coupled with proven reliability and solid value,
the LS Series loudspeakers deliver all the features musicians
and mobile DJs demand.
Encompassing main and monitor, 2-way systems, 3-way
systems and subwoofer systems with active and passive
models, the LS Series is ideally suited to address a wide
range of sound reinforcement system requirements from
intimate clubs to large scale, high impact music venues.
Key features include twist-lock and quarter-inch connectors
across all models, steel grills to protect the drivers, recessed
steel handles for easy transport, and high order – low loss
crossovers that ensure accurate reproduction of music
sources. Carvin’s LS Series loudspeakers are just what your
audience has been waiting for.
The active LS1801A powered subwoofer takes the guesswork out of selecting the ideal power source to drive your
subwoofer. The internal amplifier is perfectly mated with the
driver, making setup and operation easier with less gear
to haul. The active crossover can be engaged for 80Hz
or 120Hz, with switchable high pass on the XLR output.
Class-D operation and switchmode power technology keeps
the amp module cool running and lightweight. Built-in limiters
help prevent clipping distortion and protect the driver.
Going one step further, all LS Series loudspeaker enclosures utilize cross grain laminated multi-ply hardwood
construction. Why is this important? Unlike other materials,
multi-ply hardwood construction results in a lightweight, rigid
enclosure with reduced flex and sonic coloration caused by
cabinet resonance, and the added benefit of a more structurally robust enclosure designed to handle the rigors of the
road. The rugged black Duratuff™ covering adds another
layer of protection from dents and scrapes. The Carvin Audio
LS Series loudspeakers look every bit as compelling as they
sound!

CHOOSING THE CORRECT AMPLIFICATION
Carvin Audio LS Loudspeakers are designed to be used with
profe ssional power amplifiers capable of producin g the correct
power into equivalent speaker loads. Care should be taken to avoid
amplifier clipping. A lower power amplifier driven into clipping is
more likely to damage a speaker than a higher power amplifier used
without clipping. If an amplifier is extremely over driven, the output
waveform can approach that of a square wave. Under these extreme
conditions, an amplifier is capable of producing far more power than
its un-distorted rated power output.
Ideally, Carvin Audio recommends an amplifier with an RMS power
output which is at least the speaker’s RMS power rating, and less or
equal to the Program power rating of the speaker.
(See SPECIFICATIONS).
Always turn on the amplifiers after the mixer and control systems
have been powered on. This will eliminate power peaks due to switch
on surges which can damage loudspeakers. When powering down the
system, reverse the sequence and switch off the power amplifiers first.
SUGGESTIONS FOR OPTIMAL PERFORMANCE
• To help control feedback and to correct for venue characteristics, use a
graphic EQ or a speaker management controller.
• For optimal coverage and dispersion, elevate the high frequency horns
above eye level.
• For optimal headroom, select an amplifier with RMS power output
between the RMS and Program power ratings of the loudspeaker system.
• Ensure all amplifiers are supplied and connected to properly rated AC
power circuits. Amplifiers not getting enough AC power may cause premature clipping distortion which can damage speakers.
SPEAKER CABLES
Use either Carvin’s professional 1/4” speaker cables for up to 50 feet.
18GA cables are not recomended. Use high-current 12GA Twist-Lock
cables for longer lengths up to 150 feet or when using high power
amplifiers. You can DAISY-CHAIN up to one additional speaker per
cable by using the 1/4” OUTPUT connector, or chain several using the
Twist-Lock connector. Be sure the total impedance to the amplifier is
not lower than the amplifier’s minimum impedance.

1. INPUT 1 XLR and 1/4” (TRS) JACK
Use these as the primary input from a mixer. Using an XLR or 1/4”
TRS cable from a balanced source will reduce noise which may
be picked up by the cable. You may daisy-chain as many powered
systems as you wish with the OUTPUT XLR (see #3).
2. LEVEL CONTROL
Adjust the overall volume of the subwoofer.
3. OUTPUT XLR
Use the second XLR to link as many active powered systems as you
wish.The signal may be affected by the HIGH PASS switch (see #4).
4. HIGH PASS OUTPUT SwITCH
The HIGH PASS switch changes the signal at XLR THRU from FULL
range (parallel with Input) to HIGH PASS output (all frequencies above
the 120Hz/80Hz crossover switch setting).
This is useful when connecting to amplified top cabinets so they can
deliver more clean power to frequencies above the crossover setting,
with the subwoofer handling the lower frequencies.
5. CROSSOVER byPASS SwITCH
The crossover bypass switch bypasses the internal active crossover
allowing the use of an outboard active crossover.
6. CROSSOVER FREqUENCy SwITCH
The CROSSOVER FREQUENCY switch selects the highest frequency
to produced by the subwoofer. The 120Hz (OUT) setting is generally
used with small to mid-sized speakers in your setup. The 80Hz (IN)
setting is generally used with larger speakers.

7. PROTECT LED
If the system should go into protect mode, the YELLOW LED will light
and the power amp 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 speakers or
wiring has developed a short, or c) the power amps require service.
8. CLIP LED
The RED CLIP LED will flash if an internal power amp start to distort.
Turn the LEVEL controls down to avoid distortion. Damage to the drivers can result from operating at a level where the RED CLIP LED is
constantly illuminated.
9. POwER SwITCH and LED
Push this switch to the “ON” position to apply power to the unit. The blue
POWER LED will light to show the system is on. Power up your mixer
first, then turn on the LS active speaker. When shutting down, turn the
LS active speaker off first, then turn off the mixer.
10. AC POwER
The AC POWER JACK will accept 90VAC to 250VAC, 50Hz or 60Hz.
Plug the cord into a grounded 3 prong power source. No attempt
should ever be made to use the AC cord without the ground connected.
A locking AC cord (Carvin part# 120V18L7) is supplied. However, a
standard AC cord can be used. (for European 230V use a CEE-7 plug
cord set).
To detach the cord from the subwoofer, press the release lever on the
top of the cord near the power switch.

LIMITED WARRANTY
Your Carvin loudspeaker is guaranteed against failure due to manufacturing defects for 5 YEARS,
or 1 YEAR for active electronics, unless otherwise stated. Carvin will service and supply all parts at
no charge to the customer providing the unit is under warranty. Shipping costs are the responsibility of the customer. CARVIN DOES NOT PAY FOR PARTS OR SERVICING OTHER THAN OUR
OWN. A COPY OF THE ORIGINAL INVOICE IS REQUIRED TO VERIFY YOUR WARRANTY.
This warranty does not cover, and no liability is assumed, for damage due to: natural disasters,
accidents, abuse, loss of parts, lack of reasonable care, incorrect use, or failure to follow instructions. Warranty does not cover burned out drivers caused by excessive power or distortion, or
physical damage caused by general use, moisture or dust. This warranty is in lieu of all other warranties, expressed or implied. No representative or person is authorized to represent or assume
for Carvin any liability in connection with the sale or servicing of Carvin products.
CARVIN SHALL NOT BE LIABLE FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES.
MAINTAINING YOUR EQUIPMENT
Avoid spilling liquids or allowing any other foreign matter inside the unit. The panel of your unit
can be wiped with a dry or slightly damp cloth in order to remove dust and bring back the new look.
As with all pro gear, avoid prolonged use in caustic environments (salt air). When used in such an
environment, be sure the equipment is adequately protected. CAUTION: Square wave distortion
from power amps can destroy drivers much faster than clean RMS power.
