CARVIN SCX 1112 User manual

Carvin’s SCx 1000 series loudspeakers are a durable high performance solution for bands and audio companies
for small to mid sized venues. They feature the latest innovations for both live sound and recorded music
playback, incorporating drivers that deliver clear, very musical sound quality at high volume levels up to 134
dB. Smart crossovers with Speaker Guard™ circuitry protect high frequency drivers from overload. Rugged
construction features CNC machined, multi-ply Baltic Birch enclosures protected with UV and weather resistant
Duratec™coating and powder coated radiused steel grills. NL4 twist-loc input connectors, pole mounts, large side
handles and recessed pockets for stacking add to a list of great performance values that are designed for today’s
pro audio.
The SCX1112 is a 12” 2-way enclosure for smaller applications and great for vocal stage monitors. The full range
1200 watt peak power rating and high SPL output permits the performer to really hear their mix. The 60x90 degree
horn is vertically oriented for even floor monitor coverage at close or far angles, and horizontal pole-mounting
provides wide audience coverage when used as front-of-house mains in smaller venues and events.
The SCx1115 is a 15” 2-way multi-purpose enclosure for front of house mains, stage monitors, or DJ sound.
Loaded with a 15” heavy-duty woofer, it will handle up to 1600 watts peak. This is an exceptional sounding
enclosure for most applications requiring extended bass from a small enclosure.
The SCx1253 is a high performance, compact, dual 15” 3-way loudspeaker. The 15” woofers are co-planar
mounted resulting in a compact size that produces exceptional bass with real low-end punch. The 6 1/2” mid-range
horn loaded driver adds a new dimension of clarity to vocals and drums. The high frequency mylar compression
driver features a 90x50 degree horn with a 1-inch exit extending response to 20kHz. The NL4 twist-lock input
connectors allow for easy bi-amping. With a 4 ohm impedance and staggering 3200 watt peak power handling, this
wide dispersion loudspeaker system delivers a high intelligibility, studio quality sound with a high SPL peak output
of 134 dB. There is nothing on the MI market matching it’s sound or output at this size and weight.
For more low-end thump, all SCx systems can be supplimented with SCx1118 passive subs or SCx1118A active
subs. The heavy-duty 18” woofer is housed in a bass reflex enclosure delivering sub-bass down to 35 Hz, adding
real depth and feel to your performances. The 8 ohm, 3” voice-coil is designed to handle up to 2000 watts peak.
The active model features an internal 1400 watt power amp. Ideal for multi-stacking or stacking mains on top, this
compact hi-output subwoofer is a real work-horse that you can depend on, night after night.
Step up to a new experience in high performance sound with Carvin’s SCx loudspeakers.

1. FULL RANGE/BIAMP SWITCH (SCx1112, SCx1115, SCx1253)
Slide switches to the FULL RANGE position when using a single amplifier delivering
a full range signal. (The internal passive crossover network divides the signals and
delivers to the appropriate drivers.) Replace the rubber plug to seal the cabinet.
Slide switches to BIAMP position when using external active crossover and multiple
amplifiers in a bi-amp configuration. The BIAMP position bypasses internal passive
crossover network. Replace the rubber plug to seal the cabinet.
For the 3-way SCX1253, the Mid-High crossover network stays in place, leaving the
dual 15” drivers to be powered seperately.
2. FULL RANGE/CROSSOVER SWITCH (SCx1118)
To use an amplifier without an external active crossover, use the CROSSOVER
position to engage the internal passive crossover network.(150Hz/6dB/oct.
Slide switch to the FULL RANGE position when using an amplifier driven by an
external active crossover. (The internal passive crossover network is bypassed)
Replace the rubber plug to seal the cabinet.
3. NL4 FULL RANGE / BIAMP INPUT
This input can be used for Full Range or Biamped Input, but must be used for BIAMP.
4. NL4 THROUGH
This jack is wired in parallel with the full range input jack for daisy chaining additional
enclosures. All 4 pins are connected in parallel with the Input.
5. 1/4” INPUT
Use this input when using a single amp configuration. Ensure switches are in FULL
RANGE position.
6. 1/4” THROUGH
This jack is wired in parrallel with the 1/4” input jack for daisy chaining additional
enclosures. Ensure switches are in FULL RANGE position.
1. INPUT/THRU OUTPUT Use the balanced XLR or 1/4” connectors featured
on the rear control panel to connect to your mixer. Using a balanced source will
reduce noise which may be picked up by the cable. You may DAISY-CHAIN as many
systems as you wish. All connectors are wired in parallel, unless the HI PASS switch
is used.
2. 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.
3. POWER/PROTECT/CLIP INDICATORS 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.
4. POWER SWITCH Push this switch to the UP position to apply power to the
unit. The POWER LED will light to show the system is on.
5. 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.
6. CROSSOVER BYPASS SWITCH The crossover bypass switch bypasses
the internal active crossover allowing the use of an external active crossover.
7. CROSSOVER FREQUENCY SWITCH The CROSSOVER FREQUENCY
switch selects the internal crossover point. The 120Hz (swich out) setting is generally
used with small to mid sized speakers in your setup. The 80Hz (switch in) setting is
generally used with mid to large speakers. The SCx1112 is usable with either setting
depending on preference, but 80Hz is recommended for use with the SCx1115 and
SCx1253 to eliminate muddiness in the 120Hz range from multiple sources.
8. HI PASS OUTPUT SWITCH The hi pass output switch changes 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.
Carvin’s SCx1118A powered system takes the guesswork out of selecting the
ideal power source to drive your subwoofers. Designed to handle the most
demanding applications, the amplifier pack is perfectly mated with the sub-
woofer and enclosure, creating an optimally designed system that is ready
for anything you throw at them. The SCx1118A powered system makes setup
and operation easier as well, with less gear to haul. Feed your mixer’s output
directly to these loudspeaker systems, and you’re ready to rock!
CHOOSING THE CORRECT AMPLIFICATION
SCx Loudspeakers are designed to be used with professional power amplifiers capable
of producing the correct power into equivalent speaker loads. Care should be taken to
avoid amplifier clipping. Due to the fact that music signals have a high peak-to-average
“crest” factor, a lesser power amplifier driven into clipping is more likely to damage a
speaker than a higher power amplifier used within its ratings. When an amplifier is over
driven, its output waveform is clipped or squared off reducing the crest factor. 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. The use of amplifiers with outputs
greater than those recommended is discouraged.
Carvin recommends an amplifier capable of producing at least the power rating
of the speaker up to 1.5 times the power rating of the speaker. (See TECHNICAL
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.

SYSTEM SETUPS
Speaker systems can be scaled from small to large for the size of the venue
and type of performance, using different speakers in different positions as you
grow a system. For instance a single pair of SCx1112’s or SCx1115’s on pole
stands may be all that is required for a certain situation. Adding SCx1118 or
SCx1118A subs will expand your system for bigger performances, while still
making use of your initial investment. Larger systems add the SCx1253 for main
audience coverage, with the SCx1112 or SCx1115 as stage monitors or side fill.
For the most demanding applications, two SCx1118(A)’s can be used (per side)
to keep up with the high SPL output of one SCx1253 per side.
The SCx1000 loudspeakers feature internal passive crossovers, allowing you
to build systems using full range audio from your power amps with excellent
results.
BIAMPING AND ADVANCED SYSTEM CONTROL
With the SCx1118A, use the XLR THRU jack with the HI PASS OUTPUT switch
engaged to drive the power amp for your SCx1112 or SCx1115 to reduce the
power needed to drive these cabinets.
Active electronic crossovers such as Carvin’s XD360 X-Drive can be used for
more advanced control. Bi-amping, and 2- or 3-way setups allow more efficient
use of speakers and power amps. See the chart for recommended crossover
frequencies.
STACKING AND USING SPEAKER STANDS SAFELY
Ensure that the floor, stage or soundwings are level and solid. Be cautious
of outdoor windy conditions, speaker stacks could topple over in high wind
conditions or be accidentally pushed or bumped over by over-zealous crowds.
Loudspeakers producing very high SPL (especially subwoofers) can shift from
their original position. Ensure the feet of the loudspeakers are locked into the
feet cups of the speaker below. Place frictional material between the floor and
the loudspeaker.
