Introduction
General
The XTD is designed as an easy-to-set-up, high performance digital crossover.
It is designed to match the most commonly used speaker types currently
produced by several manufacturers. The 96kHz sample rate, 24-bit resolu-
tion and flexible firmware assures it will meet the demands of future speaker
designs. It may be used with other equipment, such as room equalization
equalizers, to isolate specific functions and provide a complete audio
processing system. The XTD is compatible with all commercially available
sound processors.
Scope of this Manual
This manual is to aid in the installation and operation of the XTD-33 Digital
Crossover. Because the XTD is designed for use with specific speaker systems,
there may be situations that the XTD cannot correct (e.g., a room with
excessive acoustic absorption or a power amplifier without sufficient power).
Please contact USL if you have any questions
Safety Notices
Review the following safety precautions to avoid injury and prevent damage
to this product. To avoid potential risk, use this product only as specified and
only for the purpose described in the instruction manual.
To Avoid Fire and Personal Injury:
• Use Correct Power Cable. Use only the power cable provided. Ensure
that the AC power outlet is located near the product and is easily acces-
sible.
• Use a Correctly Grounded Power Source. The Power Supply earth ground
is established through the ground conductor in the power cable. To avoid
the potential of electric shock, the ground conductor must be correct.
• Observe Source Ratings. To avoid risk of fire or electric shock, the power
source must be 110 - 120 VAC, 60Hz or 220 - 240 VAC, 50 Hz.
• Do Not Operate this Product with Any Enclosures Opened or Removed.
• Avoid Exposed Circuitry. Do not attempt to open the Power Supply be-
cause its safety certification would be invalidated.
• Do Not Operate with Suspected Failures. If you suspect there is damage
or malfunction with this product, call the factory.
• Do Not Attempt Repair. Only a trained factory service person is autho-
rized to repair this product.
• Do Not Operate this Product Near Heat Sources. This product should not
be located near heat sources such as radiators, heat registers, or stoves.

• Provide ProperVentilation. The operating temperature should be between
0º C and 50º C. The humidity should be <90% at 40º C or below and
<60% at 41º C to 50º C. The cooling method is by convection.
• Keep Product Surfaces Clean and Dry. Disconnect the power cable from
the power source before cleaning. Do not use liquid cleaners or aerosol
cleaners. Use a damp cloth for cleaning.
• Do Not Push Objects Into Opening of this Product. Never insert objects
into the product through openings.
• Do Not Operate In Wet or Damp Conditions.
• Do Not Operate In an Explosive Atmosphere.
• Prevent the Spilling of Liquids onto the System Components.
• Inspect the power cable and all cables prior to use. Confirm that the
power cable and other interconnecting cables are free from damage.
Safety Standard
The EN 60065 standard specifies safety design requirements that reduce or
eliminate the risk of personal injury to both the product user and service
personnel. This product is designed and tested to meet the standards of the
International Electrotechnical Commission (IEC) European Norm (EN) 60065
(The Standard for Information Technology Equipment Including Electrical
Business Equipment).
Unpacking
The shipping box contains:
This Owner’s Manual
XTD-33 Screw Terminal Plugs (4)
Power Cord IEC type for the country specified when ordered
Backup Power Transformer (Stepdown Transformer also required for the
Backup Transformer in 230 VAC systems)
Configurations
The XTD has three available channels which may be configured with two or
three bands for each channel simultaneously. Inputs and outputs may
individually be configured as balanced or unbalanced. When an input or
output is used in the unbalanced mode, the negative signal should be
connected to signal ground (“E”).
Options
If the standard speaker selections do not match your configuration, USL may
be able to provide you with a customized program to optimize your audio.

1. Output Level Adjust - Nine multi-turn potentiometers to set the individual output levels for each
frequency band in each channel.
2. Bypass Mode - These switches configure the bypass electronics for either two-or-three-way opera-
tion (should always be set to match the speaker configuration). Up (or ON) is two-way; Down (or
OFF) is three-way. All switches must be set the same way - either all Up or all Down.
3. Program Select - These two switches determine the processing applied to the signals and output
configuration. These must be set to match the speakers according to the chart in the Appendix or
the speakers may be damaged.
4. Signal Input LED - These indicate whether the XTD is receiving the proper signal level. Off indi-
cates the level is below -54 dB. Green indicates the signal is present at normal levels. Yellow
indicates the signal is within ±0.5dB of the 0dB (300mV rms) reference point. Red indicates that
the signal is over +23dB and in danger of clipping or distorting.
5. RS-232 Port - This port is used to update the firmware. This must be done by a qualified techni-
cian. Instructions are included in the update package.
6. Power LED - Under normal conditions, with the Power Switch On and no faults, the LED will be
Green and the unit will be operating in the Digital Mode. If the unit is operating in the Bypass
(analog) Mode, the LED will be Red and may indicate that servicing is required.
7. Power Switch - Controls the primary power to the XTD. Must be On to operate in the Digital
Mode.
8. Access Panel Cover - Protects the XTD settings and keeps the dust out.
