Congratulations on your selection of the TRx loudspeaker. TRx represents
Carvin's highest performance sound reinforcement loudspeakers. The TRx
series was designed from the beginning as a complete system using the highlevel components needed in a professional sound rig. The TRx series includes:
12" and 15" dual angle 2-way monitor/mains speakers, a 15" 3-way medium
throw passive or triamp mains speaker and a powerful dual 18" subwoofer.
Each TRx cabinet is constructed of cross grain 13 ply laminated Baltic Birch
plywood with internal bracing to increase efficiency and eliminate cabinet
resonance. Specially selected drivers for each loudspeaker assure optimum
performance and each enclosure is covered in Carvin's Duratex™ scratch-
resistant, UV stable, weatherproof polyurethane finish. For install and concert
rigs, the TRx series includes fly point on all enclosures except subwoofer.

CHOOSING THE CORRECT AMPLIFICATION
TRx 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.

1. NL4 INPUT
Used when using external crossover to deliver only subwoofer frequencies.
(TRx218 does not have an internal passive crossover).
2. NL4 THROUGH
This jack is wired in parrallel with the input jack for daisy chaining additional
enclosures.
1. FULL RANGE PASSIVE/TRIAMP SWITCHES
Slide switches to FULL RANGE PASSIVE 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.)
Slide switches to TRI AMP position when using external active crossover and multiple amplifiers in a tri amp
configuration. (TRI AMP position bypasses internal passive crossover network.)
2. NL4 FULL RANGE INPUT
Use this input when using a single amplifier delivering a full range signal. (The internal passive crossover
network divides the signals and delivers to the appropriate drivers). Ensure switches are in FULL RANGE
PASSIVE position.
3. NL4 FULL RANGE THROUGH
This jack is wired in parrallel with the full range input jack for daisy chaining additional enclosures.
4. NL8 TRIAMP INPUT
Use this input when using external active crossover and multiple amplifiers in a tri amp configuration.
Ensure switches are in TRI AMP position.
5. NL8 TRIAMP THROUGH
This jack is wired in parrallel with the tri amp input jack for daisy chaining additional enclosures.
1&2. NL4 INPUT JACK
These jacks are wired in parallel and serve as a full range input or a biamped input depending upon switch selection (must remove front grille and woofer to change
from full range to biamp mode, see figure C.

TCSHK10), the forged steel Quicklink™ connectors (model number
TCSHK15).
Visit www.atm-fly-ware.com for more rigging information and hardware.
IMPORTANT NOTE
The mounting/rigging points of the TRx loudspeakers must
either be used for mounting hardware (eyebolts) or “plugged”
with the hex-socket screws provided. There are two reasons for
this. When suspending the loudspeaker from one end, the
screws in the mounting/rigging points on the other end transfer
the load through the internal steel bracing to the bottom surface
of th enclosure for structural support. Also if they are not
“plugged”, the holes can create air leaks compromising the low
frequency performance of the enclosure.

RECOMENDED CROSSOVER FREQUENCIES
Low/Mid Mid/High
TRx153 400Hz - 700Hz 2.5kHz - 4kHz

TRx152 1.75kHz - 3kHz
TRx122 1.75kHz - 3kHz

TRx218 80Hz - 100Hz
De-Rating:
Using the mounting points at an angle will de-rate
the “WLL” (working load limit) for each point. Each point
mounted at an angle should be de-rated according to the following
formula.
“WLL”=cosine(angle) x 500
angle = degrees form vertical pull
500 = WLL for each TRx mounting point @ vertical pull
WARNING – Never exceed the “WLL” throughout the
suspension system.
FLYING AND STACKING INFORMATION
Prior to suspending or stacking any TRx Audio loudspeaker
systems, it is essential that the user be familiar with overhead
suspension and stacking techniques, load ratings, and safety
considerations.
SUSPENSION
TRx series loudspeakers are fitted with captive 3/8”-16 threaded nuts
for suspending or permanent installation. Each captive nut has a WLL of
500 lbs. (226 kg.).
Note: Working Load limits are based on vertical pull or 0°, for derating please
see derating note below.
DANGER:
1) Hardware found at your local hardware store should not be
used as it may not be rated for this application.
2) Mounting or rigging loudspeakers is a serious endeavor, always
seek the advice of qualified experts.
3) Never use the handles for suspending the loudspeaker, they are
not designed or rated for this purpose.
4) Improper installations may result in damage, injury or death.
CAUTION: All hardware used for overhead suspension should
be designed and used with a minimum 5:1 design factor. This is
the ratio between the structural failure point and the loading to be
applied to the component. Periodically inspect and maintain all
rigging points on the loudspeaker and all suspension hardware.
NOTICE: The user assumes liability for proper design,
installation and use of rigging systems.
STACKING
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.
