Redline™System Overview
Redline is the newest powered point‐source loudspeaker from EAW. Drawing from EAW’s deep legacy
as a manufacturer of high‐end touring loudspeakers, Redline is designed specifically for the
professional audio user in corporate AV, rental & staging, and installation. Every feature is optimized to
make these users’ lives easier.
The Redline family consists of three models –a 12” two‐way, 15” two-way and 18” subwoofer. All
three models incorporate a complete amplifier and processing module, including over 1,250 watts of
Class‐D Power‐Factor‐Corrected bi‐amplified power (1,000 watts for the subwoofer). Our 12” and 15”
mains feature EAW’s signature Focusing™ for a pristine impulse response, and all Redline models
incorporate EAW’s new DynO™ dynamic optimization algorithms to maintain this fidelity at even the
highest output levels.
RL12 and RL15 mains each include three pre‐defined, pre‐tuned voicings for mains, monitor and mains
with sub configurations. Each of these mains features a symmetrical enclosure and swappable
amplifier module to easily form mirror‐image monitor pairs. RL18S subwoofers feature a push‐button
cardioid function that allows you to create perfect cancellation behind the stack with two loudspeakers
(one rotated). All Redline models feature 18‐gauge steel grilles, hyper‐black EAW logos and EAW’s
signature RoadCoat™ finish shared with many other EAW touring products such as Microwedges and
Adaptive Systems.
In short –Redline gives professional users what they need most: rapid setup, spectacular sound with
little fuss, application flexibility, and long‐term reliability, all wrapped in styling that radiates
professionalism.
Unpacking
You should have visually inspected the outside of the shipping carton and noted any damage on the
shipping bill you signed. After unpacking, if you find concealed damage to the loudspeaker, save the
packing materials for the carrier's inspection, notify the carrier immediately and file a shipping damage
claim. Although EAW will help in any way possible, it is always the responsibility of the receiving party
to file any shipping damage claim. The carrier will help prepare and file this claim.

Audio Connections
Analog Audio
Connect the output from your line-level signal source to the XLR-3F INPUT connector on the rear
panel. This is an electronically balanced input. Users must provide their own XLR cables. The two
XLR-type connectors on the rear of each Redline series product, one female and one male, are
designed for professional audio signal levels, nominally 0 dBu (= 0.775 V). Normally, use the female
XLR as the signal input. Use the male XLR as a loop-thru output to connect the same signal input to
additional Redline products.
The wiring convention is as follows:
Pin 1: Shield
Pin 2: +/Hot
Pin 3: -/Cold
AC Mains Connection
Connect the supplied AC mains cord to the Neutrik® powerCON® socket on the rear of the
loudspeaker. Connect the other end to an AC mains supply receptacle, nominally 115 V 60 Hz or
230 V 50 Hz as labeled on the loudspeaker. If necessary, have a qualified electrician change the
cable plug as required for compatibility with the local ac mains receptacle.
WARNING: Before connecting a Redline loudspeaker to the AC mains supply,
completely turn down the input signal to the loudspeaker using the input level attenuator. If not,
there could be excessive and possibly damaging sound levels from the loudspeaker when
energized.
There is no power switch on the loudspeaker. When connected to the AC mains the loudspeaker
will be fully operational, with the output level controlled by the signal source feeding the
loudspeaker and level of the input attenuator.
Linking power
The Neutrik® powerCON® AC mains and AC loop connectors
are wired in parallel to provide an AC mains inlet and outlet
on each Redline product. The blue AC mains inlet mates with
a Neutrik® powerCON® NACFC3A (supplied). The white AC
mains outlet mates with a Neutrik® powerCON® NACFC3B.
Therefore, to loop the AC mains from enclosure to enclosure,
connect an AC mains jumper cable as shown (jumper is not
included with Redline series products).

13
Up to four additional RL12 or RL15’s can be looped in this fashion. Use an AC loop connector to
daisy-chain AC mains power from one enclosure to another. The maximum, continuous load must
not exceed 12A for the 115V version and 6A for the 230V version.
NOTE: The circuit breaker only protects the AC loop outlet, not the AC mains connector. If the
continuous load connected to the AC loop outlet exceeds the rated load, the circuit breaker will
trip. For this situation, reduce the connected load and then manually reset the circuit breaker.

Limit
The limiting parameters set in Redline Products are engineered to provide a high level of
protection for the drivers while maximizing sonic performance and output. The Limit indicator in
the rear input panel illuminates when limiting is occurring. If this is flashing occasionally, meaning
no more than once every 3 seconds or so, then levels are probably OK, but at maximum.
If this indicator is flashing more than once every 3 seconds or so, reduce the input signal level.
Clip
The Clip indicator on the rear panel illuminates if any of the Redline electronics are being driven
into clipping. This includes the entire signal chain from the input stage through the DSP. Clipped
signals can more easily damage drivers as they can raise the average signal level significantly with
a spectrum that differs from the input signal. If the Clip indicator is flashing this indicates an

14
unacceptable overdrive in the system, reduce the input signal level or damage to the drivers is
likely to occur.
CAUTION: Electronic limiters cannot provide absolute protection against driver failure. Thus, if
limiting is occurring, it is a warning that excessive signal levels are being approached. It is NOT an
indication that the loudspeaker is successfully protecting itself.
Operating Limits
While the processing for Redline series products includes robust driver and amplifier protection
algorithms and circuits, it is ultimately the responsibility of the audio system operator to operate
the loudspeakers within their capabilities. This is the only way to ensure that loudspeakers are not
stressed beyond their limits to the point of damage or failure. Operation beyond their capabilities
usually includes, but is not limited to, one or more of the following conditions:
Severe amplifier clipping
Noticeable distortion
Mechanical noise (such as cones bottoming out)
The Redline products have both Limiter and signal indicators. It is recommended that the operator
have a meter display calibrated to indicate the level where the Limiting and Clipping point are and
thus be near to exceeding their capabilities
Adjusting the Output Level
Starting with the input level attenuator at -∞(all the way to the left), turn the input attenuator
up until the desired volume is reached, but below the point where the CLIP and/or LIMITER ACTIVE
lights illuminate.
CAUTION: If there is no sound, turn down the signal source's output level before investigating
the problem. Do this to avoid excessive and possibly damaging sound levels from the loudspeaker.
CAUTION: Excessive clipping and limiting of the input signal should be avoided as it could result
in damage to loudspeaker transducers.
LED Dim
For aesthetically sensitive situations where the LED indicators of the rear of Redline may be
distracting, the LED light level can be reduced. To dim the LEDs, hold the ‘Mode’ button for 2
seconds. To restore the maximum LED brightness, repeat the same process, by holding down the
‘Mode’ button for two seconds. Note that for approximately one second after dimming or
restoring the rear-panel LEDs, the voicing mode cannot be changed. This occurs because the LED
state is being stored to non-volatile memory in order to persist through a power-cycle. This
function has no effect on audio output.

15
Onboard Processing/Voicing
Voicing Options - RL12, RL15
RL15 and RL12 feature three distinct voicings to accommodate a wide range of applications. To
select voicings, simply press the ‘Mode’ button on the back panel until the desired voicing is
illuminated.
Main
Select the ‘Main’ voicing when using the RL12/15 without a subwoofer.
The ‘Main’ voicing optimizes internal processing to maximize low
frequency response for stand-alone full-range use.
Main + Sub
Select the ‘Main + Sub’ voicing when using RL12/15 with the RL18S
Subwoofer to create a three-way system. It optimizes overlap
frequencies between the main and the sub to maximize overall output
performance. This mode should also be used with pairing the RL12/15
with other companion subwoofers.
Monitor
Select the ‘Monitor’ voicing to optimize RL12/15 for use when placed on
the ground horizontally. This voicing compensates for acoustical
coupling with the ground, providing optimized performance when using
RL12/15 as a stage monitor.

16
Voicing - RL18S
The RL18S subwoofer features three distinct voicings to accommodate a wide range of
applications. To selection voicings, simply press the ‘Mode’ button until the desired voicing is
illuminated. Normal mode provides maximum output performance. Cardioid mode provides low
frequency cancellation behind an array of subwoofers and can reduce greatly unwanted low
frequency energy from spilling onto a stage.
Normal
Select the ‘Normal’ voicing to optimize RL18S for standard
operation when used alone, or with other RL18S subwoofers for
maximum output performance.
Cardioid Front
When using 2 or more RL18S subwoofers in a cardioid
configuration, select the ‘Cardioid Front’ for the RL18S
which is oriented towards the intended coverage area (see
the “Cardioid Configurations” section in this manual for
more information on valid arrangements).
Cardioid Back
When using 2 or more RL18S subwoofers in a cardioid
configuration, select the ‘Cardioid Back’ for the RL18S which
is oriented away the intended coverage area. (See the
“Cardioid Configurations” section in this manual for more
information on valid arrangements)

17
DynO™
DynO™ is a revolutionary processing technique
that allows EAW Engineers to maximize output
from a given amplifier –transducer combination.
As opposed to conventional limiting which simply
views amplifier output and driver power handling
in aggregate (i.e. a driver can handle 100 watts or
an amplifier can produce 500 watts), the DynO
process involves much more detail and
complexity. By studying the headroom of all electronic and acoustical devices frequency by
frequency and utilizing frequency‐dependent limiting algorithms in combination with more
traditional band-pass limiting, a system’s broadband headroom can be maximize regardless of the
input signal spectrum.
EAW Focusing™
Even in well-designed professional loudspeakers, inherent
sonic flaws such as phase plug reflections, horn
resonances and cone resonances can cause undesirable
audible artifacts. Implemented through advanced digital
signal processing, EAW Focusing™generates complex
filters that correct these imperfections and improve the
transient response of a loudspeaker. This is accomplished
by isolating linear, time invariant and spatially consistent
anomalies in a loudspeaker’s response and eliminating
them through advanced processing. The result is a high
output, controlled loudspeaker that provides a pristine
transient response equal to that of a direct radiating
studio monitor.

18
Redline Application Configurations
Removing the Red Strip
The red strip alongside the Redline products is adhered magnetically and
can be removed as needed for aesthetically critical situations.
To remove the red strip, carefully peel back the magnetic strip. Place the
red strip in a safe location so that it can be re-applied in for future
applications.
Rotating the horn
RL12 and RL15 feature a user rotatable horn, providing exceptional application flexibility and the
ability to maintain the 90ox 60ocoverage pattern when the speaker is mounted horizontally. To
rotate the horn, please follow the steps outlined below.
1. Remove the red strip to access the retaining screws
securing the grill in place.
2. Remove the 10 retaining screws securing the grill in place
using a standard Philips head screwdriver.
3. Remove the HF horn/driver assembly by unscrewing their
retaining screws using a 3/16” hex key.
4. Carefully lift the HF horn/driver assembly from the baffle
5. Rotate the HF horn/driver assembly 90 degrees.*
6. Replace the HF horn/driver assembly back into the
enclosure and re-fasten the retaining screws
7. Replace the grille and re-fasten the retaining screws.
*The orientation of the horn can be determined by the
orientation of the horn throat opening. When the opening
is in the vertical orientation, the horn is in the default 90ox
60oconfiguration. If the opening is horizontal, the horn is in
the 60ohorizontal x 90overtical orientation.

19
Creating Symmetrical Monitor Angles (Swapping Amplifier Modules)
Redline RL12 and RL15 products feature the ability to switch the amplifier to the opposite side of
the enclosure to create symmetrical monitor angles for mirror image pairs. To move an amplifier
to the opposite side of the loudspeaker
1. Disconnect the unit from AC supply and disconnect all analog
audio cabling.
2. Remove the 12 mounting screws using a standard Phillips head
screwdriver. Notice the top center screw indicated in the
diagram, this is not a mounting screw, but a jacking screw
location.
3. After removing the 12 screws, insert one of the standard
longer screws into the jacking screw location. This will help free
the amplifier from the loudspeaker cabinet.
4. Turn the mounting screw clockwise, pushing against the
loudspeaker and forcing the amplifier’s corner out. If the
amplifier remains fixed to the gasket it may be necessary to
use a flat head screwdriver to free the amplifier from the
loudspeaker.
5. Once free, carefully lift the amplifier from the loudspeaker and
disconnect the electrical leads at the coupling. Set the amplifier
module aside.
6. Follow the procedure above for the blank amplifier panel on the
opposite side of the loudspeaker.
7. Connect the electrical leads to the amplifier module.
8. Secure the amplifier by re-installing and tightening the 12
mounting screws.
9. Secure the blank panel by re-installing and tightening the 12
mounting screws remembering to reinsert the shorter jacking
screw in the top center position.

Application Notes
Flying Redline from threaded mounting points
Redline attachment points are designed to accept M8 hardware. Always use a minimum of two
points to suspend any loudspeaker. See section on “Rigging” later in this manual for more
information.
Arraying RL12 and RL15
Redline loudspeakers can be arrayed in various ways. However, arraying loudspeakers requires
special consideration for the overall array’s mounting angle, projection pattern, rigging/mounting
method, and for system tuning adjustments. These issues can be significantly more complex than
when the loudspeakers are used individually. The recommendations in this section may not be
suitable for particular applications or for the desired sonic results. For assistance in configuring
Redline in an array, contact EAW’s Application Support Group.
Vertical Array
1. Non-Rotated Horn (90° horizontal
coverage): Use a 90° splay between
enclosure sides.
2. Rotated Horn (60° horizontal
coverage): Use a 60° splay between
enclosure sides.
If a different splay angle is needed for proper coverage, we suggest spacing the cabinets several
feet apart, creating an exploded array to reduce comb filtering at critical frequencies.
Horizontal Array
1. Rotated Horn (90° horizontal coverage): Orient
the enclosures so the LF drivers are adjacent
(i.e. enclosure bottom to bottom).
2. Use a 45° splay between the enclosure
bottoms.
As with vertical arrays, if a different splay angle is needed for proper coverage, we suggest spacing
the cabinets several feet apart, creating an exploded array to reduce comb filtering at critical
