Dear Predator Owner,
Welcome, and congratulaons on your purchase of a new HT/1510 Predator, the agship of our Home
Theatre HT range of REL’s subwoofers! The original HT/1508 Predator bowed to instant recognion that,
here was a new category of large scale, theatre-busters. For years, that category had been dominated
by loud, heavy, slow subs that fostered the noon that big theatre was nothing more than an excuse to
make loud sounds. Whereas, those of us who have been around theatre sound from the other side of the
mastering console know how much detail and nuance goes into the making of lm sound. Here nally, in
Predator, was a sub that was lightning quick, yet with a large 15” driver and 800 was behind it, could roll
with the best, but had speed, insight, nuance.
And now get ready for something even more remarkable. HT/1510 Predator builds on where the original
le o. We stepped up to a full 1,000 wa amplier because theatre sounds best when amplier and driver
are cruising along eortlessly. The extra power allows for headroom, addional output and the sense that
you’ll likely run out of ears before it runs out of power. Adding to this are new versions of our LimitLess™
max volume limiters. These are now so transparent that it becomes dicult for even seasoned professionals
to detect when they engage. Again, it makes movies at home more relaxing as there’s nary a moment when
the Predator limiters kick in and even when they do, you likely sll won’t detect it.
The CarbonGlas™ 15” driver has been retained with even greater power handling for obvious reasons.
Speed is at the heart of this dreadnaught, but also wide bandwidth since we know that for theatre eects
to sound shaering, the subwoofer, while sll properly crossed over quite low, must be able to permit the
crack at the outset of explosions to emerge unhampered. This necessitates the light weight but also the
upper frequency bass region to be properly handled. True carbon bre holds everything together with a
large, s center cap that adds lile weight but produces the Craack! needed to be convincing.
This new Predator is imbued with elegant proporons and beauful nish treatments, the beer to integrate
into REL 3D and HT/3D systems. These call for powerful HT .1/LFE along with High Level Inputs available in
our tradional model RELs that permit connuous full range bass; this is the missing link in home theatre.
Convenonal home theatre typically delivers cold, arcial vocals followed by loud, even annoying, bass.
REL 3D/HT3D delivers rich, natural dialogue and engaging, spaally-correct Foley Eects, coupled with
prodigious .1/LFE infra-bass.
HT/1510 Predator, welcome to the new era of home theatre.
Dear Friend and Valued Customer

Always switch o your system before disconnecng any wires.
To simplify and to increase the versality of connecng, the Predator models have two low-level RCA inputs
as well as an XLR input. This is to facilitate ability to use with AV surround sound systems, two-channel
stereo systems and powered speakers.
Low-Level Inputs
.1/LFE Input
There is a single RCA jack labeled .1/LFE for LFE connecon to a processor. Plug one end of the RCA to RCA
cable into the .1/LFE jack of the REL and the other end into the SUB OUT Jack of your processor.
There is also a single XLR .1/LFE input for processors that provide this signal as a balanced output.
Stereo L/R Input
The dual RCA jacks can be used for stereo low-level connecon to the output a stereo processor source or
powered speakers. When using stereo inputs, plug one end of the RCA to RCA cables into both of the LOW
LEVEL INPUT jacks of the REL and the other end into the le and right channel output of your preamplier.
The upper frequency amplicaon of these inputs can be limited using the CROSSOVER control. This
CROSSOVER control is labeled 30Hz at its minimum. Rarely should the CROSSOVER control be set to it’s
maximum 200Hz setpoint when using either LFE or stereo inputs.
Both the RCA and XLR inputs have corresponding output connecons so that mulple RELs can be run in
parallel by connecng the OUT of one the IN of the next. This is what we refer to as “daisy chaining”.
Please note that the type of input must be maintained for daisy chaining. If the input is in the RCA, the XLR
OUT cannot be used to connect to the next amp and vise versa.
Connecng Up
12
Phase Switch
The phase control on a REL has two posions, 0 and 180. One of these posions will set the REL in phase
with the speakers, and one will set it out of phase. The labels 0 and 180 are just labels and tell us nothing
about the rest of the system, only if the REL is working with the speakers or not. Whichever posion results
in the loudest and fullest sub bass, is the correct posion.
We want the REL to work in harmony with the speakers, reinforcing bass, not cancelling it. In other words,
we want the drivers in the speakers and the REL to move forward at the same me and move backward at
the same me. When this happens, it results in an increase in sub bass volume and the pressurizaon in the
room and they are in phase. The opposite is if the speakers and REL are working against each other causing
cancelaon of low bass. We call this out of phase
13
With the REL Predator, there are two basic ways to connect and setup. The rst is a single channel input
from the sub out of a theater or power speaker system. In this case a single RCA cable is needed. The second
is a stereo input from a stereo preamp or powered speaker system. Here there will be the need for two RCA
cables. In both cases the user can set the upper frequency limit using the CROSSOVER control.
Connecng and Seng Up
Place in desired posion. While your REL has been designed to be extremely easy to posion and achieve
excellent results, careful placement along the same wall as the screen will yield improvements. Listen for
increases in deep bass output as well as precision of bass notes when seng up.
REL Set-Up Made Simple
14
1 Theater Connecon (Sub Out Connecton)
• Connect RCA or XLR cable from Sub Out of theater processor to LFE input of Predator.
• Adjust CROSSOVER control to 30Hz (minimum).
• Adjust LEVEL control to 1/4 of the rotaon up from minimum seng.
• Plug in AC cord.
• Power on with switch next to AC input.
• Set toggle below STATUS light to ON.
• Fine tune LEVEL control using a known powerful .1 chapter to make sure your seng is not too high
or damage can occur.
• Adjust CROSSOVER control lower to eliminate upper bass boom.
• DO NOT TURN CROSSOVER UP PAST 1/2 the rotaon. Doing so is unnecessary and may result in
damage to the driver.
2 Stereo Connecon (Powered Speaker Connecon)
• Connect RCA from output to right input for mono or both le and right for stereo.
• Adjust CROSSOVER control to 30Hz (minimum).
• Adjust LEVEL control to 1/4 of the rotaon up from minimum seng.
• Plug in AC cord.
• Power on with switch next to AC input.
• Set toggle below STATUS light to ON.
• Fine tune LEVEL control to blend with powered speakers.
• Fine tune CROSSOVER control to blend.
• Note that CROSSOVER and LEVEL become inverse. Meaning, as you turn up the CROSSOVER, you will
need to turn down the LEVEL.
• DO NOT TURN CROSSOVER UP PAST 1/2 the rotaon. Doing so is unnecessary and may result in
damage to the driver.
• Place carefully: While your REL has been designed to be extremely easy to posion and achieve
excellent results, careful placement along the same wall as the screen will yield improvements.
Listen for increases in deep bass output as well as precision of bass notes when seng up.

3 Phase Orientaon
Once connected, we need to adjust for phase. This may be the single most crical step, and because
it really is quite simple, it is oen over-thought. Keep in mind; the right phase is whichever posion is
the loudest or fullest. While playing music with true low bass, adjust the crossover to a point where the
REL and the speaker are sure to share frequencies at 50Hz on the crossover control, or slightly higher
for smaller speakers. At this point turn the HI/LO LEVEL control up so that both the REL and speaker are
roughly equal in volume and then switch, using the phase switch, from “0” to “180” phase posions.
Again, whichever posion is loudest or fullest is the correct posion. That is, when the posion is working
in harmony with your main speakers, reinforcing bass, not canceling it.
4 Crossover and Level Sengs:
To determine the crossover point, take the volume of the REL (using the Level control) all the way down,
and put the crossover to 1/4 of the rotaon. At this point, bring the REL’s volume back up slowly to the
point where you have achieved a subtle balance, i.e. the point at which you can just hear the Predator
even with the main speakers playing. First, bring the crossover point up unl it is obviously too high;
now gently reduce frequency to the appropriate seng. For all intents and purposes, this is the correct
crossover point. Once this stage has been reached, subtle changes to volume and crossover may be
accomplished to provide the last bit of complete and seamless integraon. With that, set-up is complete.
Hint: There may be a tendency to set the crossover point too high and the volume of the Sub-Bass System
too low when rst learning how to integrate a REL with the system, the fear being one of overwhelming the
main speakers with bass. In making this common error, the resulng set-up will be lacking in bass depth and
dynamics. The proper crossover point and volume seng will increase overall dynamics, allow for extended
bass frequencies, and improve soundstage properes. Note, volume adjustments may need to be made to
oset the eects of crossover changes. In general, when selecng a lower crossover point, more volume may
need to be applied. Higher crossover frequencies will generally necessitate less gain.
17
Stacking
The Predator was designed to stack cabinets on top of each other to create a line array. Each foot has a
pad on the boom to protect the vinyl on the top. Please remove the plasc covering on the pad before
stacking and take care to place the second sub on top of the rst carefully to not scratch polished top plate.
Straps are provided to secure the top sub to the boom sub safely. These are made of thick aluminum and
strap the subs together using the hardware provided. The fasteners require a 6mm hex wrench to ghten.
18
We strongly advise purchasing furniture restraints from a quality supplier to anchor stacks of Predators to
a wall. Use a quality furniture restraint made of nylon webbing or braided steel cable. Please follow the
instrucons of the restraint you choose and anchor to a structural poron of a wall.
hps://www.consumerreports.org/furniture/how-to-anchor-furniture-to-help-prevent-p-overs-a4328328212/
To operate mulple stacked Predators in parallel, REL has provided duplicate RCA and XLR connectors to go
OUT of the boom sub to the input of the top. This is provided for convenience to simply “daisy chain” from
one sub to the next with RCA or XLR cables rather than employing mulple “Y” cables.
Please note that the type of input must be maintained for daisy chaining. If the input is in the RCA, the XLR
OUT cannot be used to connect to the next amp and vise versa.
Running In
Care taken during run in will be rewarded by many years of pleasurable use. Both the electronics and the
drive unit will benet from an inial period of carefully controlled use. Possible damage may be sustained
by running in the unit at too high a volume seng over an extended period. On the other hand, by taking a
lile care over this inial period, about 24 hours of actual use, a longer life with a higher potenal eventual
performance is assured.
Care and Polishing
The cabinets are best maintained by using only a damp cloth on the vinyl. For the top, please use automobile
polish made by reputable manufacturers. Our favorites are those made by Meguiars and Mother’s. If objects
are to be placed upon the top, it is advisable to use a small mat to protect the surface and to avoid the risk
of rales.
The Predator employs an advanced lter circuit which provides exceponal performance when coupled to
the rest of the signal chain of the Sub-Bass System.
The amplier is inherently stable and will retain its characteriscs over very long periods of me – important
in a unit designed for an exceponally long working life. These ampliers are designed to withstand reasonable
abuse and overloads. If in doubt, please contact your dealer.
We believe that the importance of the electronics, cabinet and drivers being designed to work in harmony is
paramount. This belief allows Predator to achieve the highest possible level of delity.
Overload Protecon
All REL Sub-Bass Systems are designed as true sub bass speakers. They are designed to reproduce those
exceponally deep notes that are felt as well as heard. This it will aempt to do at whatever volume level
you set. If set too high no damage should result because the built-in electronics will limit the cone movement.
This electronic control is called Set-Safe™. It constantly and instantaneously monitors the output from the
power amplier and is totally transparent in operaon unl required. This means it has absolutely no eect
on the sound quality of your REL unl an overload is detected.
Ordinarily an overload would cause the power amplier to go into clipping with resultant loss of control
over the drive unit. This can cause drive unit damage, and always sounds nasty. Set-Safe™ detects the point
of incipient clipping and gently so-clips the waveform of the signal to ensure actual clipping does not occur.
This is a necessarily simplied descripon of what actually happens, but in eect, Set-Safe™ controls the
amplier and ensures there is minimum risk of amplier and driver damage caused by over-driving.
A thermal overload device is ed to all Predator Sub-Bass Systems. If the unit is deliberately over-driven
this device will sense the temperature rise and cut the output; recovery me is approximately ve minutes.
If this happens, it is a warning that the unit is being over-driven and the volume level control should be
reduced to a safe level.
Although everything possible has been done to minimize risk of thermal overload failure, there can be
no defense against those individuals who deliberately abuse the device. Such damage is NOT covered by
warranty. Please remember your REL is there to supplement your main system, not overwhelm it!

Power Saving Eciency
All REL sub bass system designs ulize a true Power On-O switch that aords the owner the ability to turn
o their unit completely, without having to unplug the A/C mains cord. When a REL sub bass system is
switched o using the Power On-O switch on the rear panel it draws ZERO power.
In addion to the power switch there is an ON/AUTO mode switch has two posions. Le is AUTO and right
is ON.
The Predator features an AUTO standby mode that is enabled when the power mode switch on the rear of
the unit is set to the “AUTO” posion. In this mode, the input signal is constantly monitored for audio acvity.
If not audio informaon is detected over a period of 30 minutes, the unit will enter a low power standby
mode in which less power is consumed. When input signal acvity is detected, the unit resumes normal
operaon. By using the standby mode, you can ensure that there is no unnecessary power draw when the
unit is not in use.
Note: Due to variaons in program material, it is impossible to produce a perfectly reliable standby circuit.
Bass rich music or eects will consistently trigger our standby circuit whilst content that is low in volume and
possesses lile or no bass cannot be relied upon to trip the standby funcon.
Alternavely, the user has the opon to leave the unit in the normal operaon mode at all mes by selecng
the “ON” posion of the power mode switch. Leaving a REL on produces the best sonic performance and
the most reliable operaon. In this mode, the unit will not enter standby regardless of whether or not there
is acvity at the input. Using this seng ensures that the Predator is ready to react instantaneously to bass
transients, whether in music or lms.
