IMPORTANT SAFETY INSTRUCTIONS
safety-4v0.pdf 04/29/03
Introduction
The TX Series processors are an essential part of any TX loudspeaker system. TX series
loudspeakers should not be used without the appropriate processor. There are different TX
processors for each of the full–range cabinets in the TX line. The TX3P, TX4P and TX8P also
provide processing for subwoofers added.
The TX processors perform several functions: Crossover, equalization, calibration, loudspeaker protection and hum rejection. The crossover function splits the input signal into different frequency bands for each driver (e.g. High, Mid, Low and Sub for TX8). Equalization
flattens and extends (LF) the frequency response. Calibration adjusts for different amplifiers to
maintain proper response independent of amplifier gain. Protection ensures that the drivers are
not driven beyond their safe limits. Hum rejection is provided by the balanced inputs and by
the remote reference feature of the output drive stage when used with unbalanced amplifiers.
1. Calibrate Button
This is the most important control on the processor. Calibration adjusts for different amplifiers
to maintain proper response independent of amplifier gain. This allows a fail safe approach
to matching amplifiers with a TX-Series loudspeaker system. Please refer to the recommended
power amplifier section for information on which power amplifiers are required for each of
the various TX-Series loudspeaker systems. If a larger than necessary power amplifier is used
with the system, the processor will simply turn down the input gain to the level.
After the system is wired and power is applied, depress the calibrate button twice (quickly). The
processor will then send tones through each amplifier and adjust the gain in the processor to the
appropriate level for the amplifier being used. This may be done with or without the loudspeakers
connected. The calibration routine is also a good test of the entire system. Listen for clean tones
from all drivers during test. There is a separate calibrate button for each input channel.
If the processor is not able to calibrate properly it will flash the mute and limit lights for
each band in error along with the calibrate light. Failure to calibrate may be due to several
causes: mis-wiring, not enough amplifier gain, amplifier gain controls not at maximum or
amplifiers turned off. If a band does not calibrate properly, the processor will be set at a low
but usable level. The flashing lights may be extinguished by depressing the calibrate button
once. If there is an error the calibrate light will remain on but not flashing. The calibrate
routine will always try to calibrate a subwoofer output but will not indicate subwoofer calibration errors when the mode is set for operation without a subwoofer.
Note: The calibration will be maintained even when the power is disconnected.
3
A default calibration may be done by holding down the calibrate button and then applying power to the processor. This will set the processor to approximate calibration. The default
calibration should only be used when regular calibration fails and there is not enough time to
find the fault. Use of the default calibration may leave the system vulnerable to damage.
Warning: Speaker damage may result if the processor is calibrated to a specific amplifier and another
amplifier of larger power or greater input sensitivity is used.
ALWAYS RE-CALIBRATE THE SYSTEM WHEN A DIFFERENT AMPLIFIER IS USED.
2. Mute Buttons
Each frequency band of each channel may be muted with the corresponding mute button. The
mute buttons are intended as an aid to tracing system problems and checking the system.
3. TX9S Mode
The TX3, TX4 and TX8 processors have an internal mode switch for use with the TX9S subwoofer.The processor cover must be removed in order to change between TX8S and TX9S. There is a
red led that can be viewed from the back of the unit to confirm the mode of operation.
4. Mode Buttons
There are two operating modes: with a subwoofer and without a subwoofer. The TX8 system is 4-way with a subwoofer and 3-way without a subwoofer. The TX3 and TX4 systems
are 2-way without a subwoofer and 3-way with a subwoofer. The TX2P and TX5P processors do not support subwoofers and hence, do not have a mode switch.
5. 3-Way / 4-Way Indicators (TX8P)
These indicate the mode that the processor is currently in. 4-way is intended for use with
a subwoofer. 3-way is for use without a subwoofer. This changes the equalization and low
frequency rolloff of the LF output. The SUB out remains active in both modes.
6. 2-Way / 3-Way Indicators (TX3P, TX4P)
These indicate the mode that the processor is currently in. 3-way is intended for use with
a subwoofer. 2-way is for use without a subwoofer. This changes the equalization and low
frequency rolloff of the LF output. The SUB out remains active in both modes.
7. Trim Controls
The trim controls allow the user to make fine adjustments to the crossover gain for each band.
The sub woofers can be adjusted +/- 6 dB while the other bands can be adjusted +/- 3 dB.
8. Power Indicator
This light indicates that the unit is receiving AC power from the mains supply.
9. Clip Indicator
This light indicates that the input is receiving too much signal, there is about 6dB headroom
from the indicated level.
10. Activity Indicators
This light indicates that there is a signal on the input of about -30 dBV or more (TX3P,
TX4P, TX8P).
11. Limit Indicators
These lights indicate that the limiters are active. They indicate even the slightest amount of
limiting hence they go on early and have a slow release.
12. Mute Indicators
These indicate that the frequency band is muted.

13. Connections
Please refer to diagrams at the back of this manual.
14. Inputs
The inputs connect to the signal source, this would normally be the last piece of equipment
in the signal processing chain or the output of the mixer. Since the signal run to the processor is usually long, it is important that the equipment that feeds the run to the processor has
a low output impedance, preferably with balanced output impedance. If the source is unbalanced ground the connection to pin 3 at the source.
15. Outputs
Since the processor should be in the same rack as the amplifiers these cables will be short
cables to the amplifiers below. It is intended that one stereo amplifier be used for the same
frequency band of 2 cabinets, but this is not essential.
16. Sense Connections
The sense cables allow the processor to monitor the output level of the amplifiers. Each
sense cable carries the same frequency band for 2 speaker cabinets. For example one cable
would carry the signal from a stereo amplifier driving two HF drivers. If the amplifier has
Speakon™ outputs for stereo/bridged mode cables, these outputs should connect direct from
the amplifier to the processor.
NOTE: The processor will not calibrate if the Left & Right connections are reversed.
17. Modified Response (TX2P/TX5P)
In response to user recommendations, TX2P processors manufactured after 07/98 have a
response that dip -6.5db at 750Hz and -4.5db at 250Hz. The response maybe returned to the
original, flattened response by turning the internal trim pots (Rt1a, b, c, and d) fully clockwise.
The TX5P features include a variable notch filter. The factory preset is 120Hz, -6db (fully
Counter-Clockwise). This is set to help eliminate boominess. The response can be flattened
by rotating the internal trim pots (Rt1a, b, c, and d) fully clockwise.
To access these trim pots, it is necessary to remove the chassis cover.

Introduction
TX processors all come with an owner’s manual which covers the specifics of system setup.
The purpose of this writing is to provide supplemental information for first-time TX users.
As well, we realize that not everyone is accustomed to the demands of operating actively
processed 2, 3 and 4-way speaker systems. We will therefore endeavor to get you started off
the right way. Once the initial setup procedures are mastered, you should find that your TX
system virtually runs itself - you do the mixing, TX does the sound.
The Processor - General:
In any advanced processed speaker system you will find certain elements. These include (1)
electronic crossovers, (2) graphic and/or parametric equalizers and (3) compressor/limiters all dedicated to speaker performance. The TX processor basically contains all three of these
elements, but with an important difference. Unlike mix-and-match systems, each TX processor has been engineered in conjunction with the development of its designated speaker to
ensure the absolute maximum performance. As a result, we do not recommend that you use
any other processor. For example, if you have TX3’s, use the TX3P, TX4’s, use the TX4P,
etc. Subwoofer processing is included in all processors but the TX2P and TX5P. A push-button subwoofer switch inside the processors selects TX9S or TX9S processing and an LED
visible through a small hole in the back of the chassis illuminates for TX9S. If the LED is off,
TX9S processing is selected.
In addition to the above elements, your TX processor contains a special gain-sensing
feature which works in conjunction with a pre-programmed calibration circuit. During the
initial speaker setup and calibration, cables which you connect from the amplifier outputs
back to “sense” inputs on the processor tell its internal auto-adjust feature where to set the
input gain. This functions like an automatic amplifier volume control, hence it is important that the actual volume controls on your amplifiers always be set at maximum. After
calibration is successfully completed, the processor will “remember” all its internal autoadjustments and the procedure need not be repeated as long as you use those amplifiers.
However, whenever you do substitute an amp, re-calibrate the system.

Amplifiers:
We specify certain Audiopro amplifiers in the TX manual. You may use others, however for
maximum performance from the system, they should have not less than the following output;
Model# Component/s Required Power per Channel
TX8 Hi (2-inch) 300 Watts @ 8 ohms
Mid (8-inch) 300 Watts @ 8 ohms
Lo(2x15-inch) 1200 Watts @ 4 ohms
TX4 Hi (2-inch) 300Watts @ 8 ohms
Lo (15-inch) 600 Watts @ 8 ohms
TX3 Hi (2-inch) 300 Watts @ 8 ohms
Lo (12-inch) 300 Watts @ 8 ohms
TX2M Hi (2-inch) 200 Watts @ 8 ohms
Lo (12-inch) 300 Watts @ 8 ohms
TX5M Hi (2-inch) 300Watts @ 8 ohms
Lo (15-inch) 600 Watts @ 8 ohms
TX9S/9S Lo (2x18-inch) 1800 to 2400 Watts @ 4 ohms (mono bridged)
If the amplifiers are higher powered, the processor will detect this during calibration
and simply adjust their input signal levels downward accordingly to maintain driver safety.
And if one or more amplifiers are of considerably lower power than the design criteria, the
CALIBRATE ERROR LED will flash along with all the other LED’s for that frequency channel.
It is advisable to use the recommended power, however if the power is marginally less than
ideal, the processor will simply adjust its gain upward. Watch for amplifier clipping if this is
the case (and generally, of course). Once again, be sure to turn all amplifier volume controls
to maximum and leave them there.
Another possible problem, mixing up any left & right channel connections, will create a
situation wherein the calibration will not work. If this happens, check your line and speaker
level connections carefully to ensure that all the various left and right channel connections are
consistent from the mixer to the TX processor to the power amps and back to the speakers.
Yorkville Speaker Cables and Connections:
Yorkville Sound offers a full range of 14 gauge speaker cables as well as the 20-gauge,
Speakon-to-bananaplug SP4-3SB “sense” lead. The speaker cables are available with 4 or 8
leads and in 25, 50 & 100 foot lengths. All speaker cables come with Speakon connectors
at the speaker ends and either Speakon or banana plug connectors on the amp ends. The
banana plug ends have numbered labels on the wires for function as follows:
SP4, 4-element cables (for TX2,3,4,5, and subwoofers) ... 1 = low frequency, 2 = high frequency
SP8, 8-element cables (for TX8) ... 1 = subwoofer, 2 = lows, 3 = mids, 4 = highs).
The banana plugs on Yorkville SP cables have a small tab on one side marked “ground”
(in very small print). This represents negative (-) terminal so that you can maintain uniform
polarity when connecting the cables to the amplifier. **Polarity is very important. The positive banana terminals on our amplifiers are grouped together for bridging purposes. But
when you are not bridging them, which would be in most cases, the banana plug connected
to either the A or B channel output posts will have to be turned upside-down so that the
negative banana leads are connected to the negative output posts.
Other Speaker Cables:
Cables other than ours should be 14 gauge or heavier. If they have banana connectors on
the amplifier ends, they should have clear markings on them for function and **polarity. To
help you rig the Speakon ends, Speakon wiring inside the TX cabinets is as follows:
TX2,3,4,5 ... +1-1 = lows, +2-2 = highs
TX8 ... +2-2 = low (low mids), +3-3 = mids, +4-4 = highs
TX9S,TX9S = +1+2,-1-2
**(Note; it is very important for the performance of speaker systems that all similar drivers have the same
polarity - in other words that the positive output terminals on the amplifiers are connected to the positive
terminals on all the drivers. For example, adjacent woofers with different polarity can actually cancel
each other’s acoustic output by as much as -10dB. The effect is like losing a large percentage of your
amplifier power. Similarly, acoustic phase alignment is important. For tips about setting up the speakers
for maximum performance, read about “close coupling” under Speakers.)
Line Level Cables and Connections:
Cables running between the mixer and processor and the processor and power amplifiers
must have XLR connectors at the TX end with applicable connectors at the other end. TX
7
processor inputs are female XLR’s and the outputs are male XLR’s. Most mixers now have
balanced outputs using 1/4-inch TRS (tip-ring-sleeve) jacks or XLRs. Power amp inputs
tend to be balanced these days too, but many of the old amplifiers still in use have unbalanced inputs. As well, certain older mixers may have unbalanced outputs. This is not a
problem because TX processors are electronically balanced with a special “Remote Ground
Reference” feature. With this feature, you can achieve the noise rejection of a totally balanced mixer-processor-amplifier setup even when the amp inputs or mixer outputs are
unbalanced, usually just by employing the right type of patch cables. To achieve balancedtype noise rejection when connecting a TX processor to an unbalanced mixer or amplifier,
use balanced, 3-element (2 centre leads plus shielding) patch or mic cables. In some cases,
just doing this will provide balanced-type noise rejection. This is because manufacturers in
the past have often used stereo input or output jacks, even though their amplifiers or mixers
were unbalanced, and interconnected the ring and ground tabs internally. This is enough for
the RGR system to work using regular balanced cables. However, if the mixer or amp does
not have this feature and you find that simply using a balanced patch cord does not cut
down on the hum or hiss, try rigging the following special cable:
Start with a balanced patch cord or mic cable with the appropriate male or female XLR
on the TX end. Keep in mind that the TX processor’s XLR wiring configuration is; pin 2 =
tip (hot), pin 3 = ring (hot, reverse phase) & pin 1 = ground. Remove the stereo 1/4” plug or
XLR from the other end being sure to twist the wire previously from pin 3 and the ground
shield wire together. Solder the “hot” in-phase wire from XLR pin 2 to the plug’s hot tab (the
shorter one). Now solder the twisted wires to the plug’s ground lug and screw on the jacket.
Finally, mark that cable with tape for future use.
Speakers - Phased Arrays:
In addition to wiring up a TX system correctly, you need to be concerned with proper setup
of the enclosures.
No more than the usual care need be taken if you are running a small system, say two
TX3’s and a TX9S on each side of the stage. However, if the system is larger and high sound
pressure is the order of the day, perhaps at an outdoor concert or in a very large venue, you
will need to array the enclosures so that their acoustic outputs are in phase.
Creating in-phase speaker arrays is basically a matter of keeping similar enclosures close
together, facing in the same direction and aligned on the same horizontal plane. This is
referred to as close-coupling. TX enclosures are trapezoidal so that similar ones, when
close-coupled, create a semicircular array and thus provide a wide coverage angle. The
TX9S subwoofers should also be close-coupled when used in multiples - although they are
not trapezoidal, low frequencies tend to be omni-directional and so they automatically have
a wide coverage angle. The TX9S subwoofers may be flown or freestanding and should be
close coupled as well.
It is not generally advisable to close-couple dissimilar enclosures when they are reproducing the same frequency range. For example, you would probably not mix TX3’s and TX4’s
close-coupled. The reason for this is that you will lose some of the potential additional
sound pressure due to the enclosures’ slightly different phase characteristics causing acoustic cancellations at various frequencies. This applies to all speaker systems. Subwoofers also
should not be mixed, and for the same reason. Mixing very different subwoofers, for example horn-loaded and non-horn-loaded, can often result in a loss of low-frequency sound
pressure because the phase characteristics are so very different. Once again, array similar
enclosures for maximum reinforcement.
8
Flying Hardware:
TX8 3-way enclosures and the TX9S subwoofers come with slots to take 30-degree angled
bars called BAR30s which lock in place with QUICKPINs to close-couple the enclosures
side by side and hold them solidly together when flown in arrays. Other flying hardware
includes SWIVLE-RINGs which lock into the upper and lower tracks for quick setup and
teardown. They accept the cable eyes or shackles (our model SHACKLE3/8A). And for permanent installations, the upper and lower tracks will accept an EYEBOLT3/8A. To install
this, simply remove the large Allen-head screw located in the bottom of the track about the
midway mark and replace it with the eyebolt.
