The LS Series from Carvin Audio are one of the best loud­speaker values on the market today, 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 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. With key features like 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 biampable crossovers that ensure accurate
reproduction of music sources, Carvin’s LS Series loudspeakers
are just what your audience has been waiting for.

The powered LS-A speakers take the guesswork out of selecting
the ideal power source to drive your LS loudspeakers. The inter­nal amplifiers are perfectly mated with the loudspeaker systems,
making setup and operation easier with less gear to haul. Active
full range systems feature 3 channel operation allowing use as a
standalone PA system with seperate inputs levels for combining
music sources (mixer/mic, instrument/mic, MP3/phone), a mix/
thru switch on the XLR output, and a 3-band EQ with mid-sweep
frequency. Active subwoofers feature a selectable active cross­over at 80Hz or 120Hz with switchable high pass on the XLR
output. Class-D operation and switchmode technology keep the
amp modules cool running and lightweight. Built-in limiters help
prevent clipping distortion and protect drivers.

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!

1. INPUT 1 XLR and 1/4” (TRS) JACK

Use these as the primary input from a mixer (or MIC, see #2). 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 (see #13).

2. MIC IN SWITCH

Use the “OUT” position for normal line-level mixer input (note: if this switch is left “IN”, signals from a mixer
will be distorted). Press this switch “IN” to add 30dB of gain to the XLR and 1/4” inputs of INPUT 1 so that
a microphone can be used.

3. LEVEL CONTROLS

The LINE/MIC 1, INPUT 2, and INPUT 3 level controls adjust the volume of each input.

4. INPUT 2

This input is designed with a high impedance (>100K ohms) for instruments such as a guitar. Other
sources such as keyboards or drum machines can also be connected.

5. INSTRUMENT SWITCH

Press the switch “IN” to provide an alternate tone for instruments on INPUT 2.

6. INPUT 3

The RCA jacks are inputs for MP3 players, CD players, keyboards, and DJ mixers. The two input signals
are combined into a mono signal. For stereo operation a second active speaker is required, with the Left
signal going to one speaker and the Right signal going to a second speaker.

7. SHAPE SWITCH

10

Press the switch “IN” to change the EQ on INPUT 3, useful for playback of pre-recorded music.

8. ACTIVE EQUALIZATION

The active powered loudspeakers offer a 3-band mid sweep equalizer for custom tuning to the acoustical
environment. The EQ system is engineered specifically for the active powered loudspeakers featuring a
modest boost and cut range of ±6dB to prevent radical adjustments that could otherwise compromise 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. These controls affect all 3 inputs.

9. PROTECT LED

12

If the system should go into protect mode, the YELLOW LED will light 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.

10. 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.

11. 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.

12. AC POWER

Use a standard grounded AC cord. Whenever possible, use dedicated circuits for powered speakers.

13. OUTPUT XLR

Use the second XLR to link as many active powered systems as you wish. (see #14)

14. OUT MIX/THRU SWITCH (for daisy chaining additional systems)
Press the switch “IN
chaining other powered systems. With the switch in the “OUT” position, the combination of all 3 channels
including the EQ are sent to the OUTPUT XLR. This unit becomes the master source for other powered
systems connected to the OUTPUT XLR.

Powered Subwoofer

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 daisy­chain as many powered systems as you wish (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. (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 for going to amplified top cabinets that can not handle the sub’s low
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.

SEE #9, 10, 11, 12 above for LED indicators and AC power.
