3. Introduction

Please read this entire manual before commencing your installation.

The USL XTM series crossover module has been designed for high performance, ease of use, and years of trouble free service. No special tools are required. The components that make up the XTM are of computer grade for reliability. All USL equipment has been “burned-in” at the factory for an extended period in order to eliminate the possibility of premature failure. Unpack the unit carefully. If the container has been damaged, thoroughly inspect the equipment to make certain that there is no hidden damage. File a claim immediately with the carrier if any damage is found. Also advise your dealer or the factory.

The USL XTM-300 is a bi-amp crossover chassis for use with the XTA-680EA analog crossover card or the XTD-680 digital crossover card, each of which provides three channels (left, center, right) of bi-amp configuration.

The XTA card provides the low cost ability to set 11 distinct crossover frequencies and 4 low frequency time delays for the left, center and right channels.

The optional XTD-680 digital crossover card provides increased flexibility for setting the left, center, right and LFE channels including parametric, screen and horn EQs, gains and delays. The card is configured with an easy to use graphical user interface that runs on a laptop computer communicating via a USB cable. A library of existing speaker types is provided, or each of the features may be configured manually.

NOTE: Although the XTD card is capable of supporting tri-amp configurations, the XTM-300 does not support tri-amp use. Should you need tri-amp support, please contact USL.

You will need to supply the following materials and tools:

• One DB25 cable (female to female) for connecting the XTM to the cinema processor (USL JSD -60).
• Two DB25 cables (female to male) for connecting the XTM to the monitor (USL CM-8E).
• Optional Phoenix connectors allow connection to amplifiers or other equipment.
• Four 10-32 x 1/2" (or M6) screws to mount the XTM-300 in the audio equipment rack.
• Screwdriver for the rack mounting screws above.
  • Wire strippers (if the terminal blocks will be used).
  • Small Phillips screwdriver (to remove the cover plate).
• Trimpot adjustment tool or small flat blade screwdriver (to adjust bypass levels).

Crossover Wiring

1. Power: Connect the unit to the AC power outlet using the standard IEC cable provided. Any power source from 100-250VAC, 50-60 Hz will be sufficient.
2. Bypass power: Connect the unit to the AC power outlet using the supplied modular power supply. Any power source from 100-250VAC, 50-60 Hz may be used by changing the AC pin adapters.
3. XTM input from processor outputs: Use the male-female 25 pin D cable to connect the output of the cinema processor to the main input of the XTM.
4. Crossover outputs to monitor inputs: Use the male-female 25 pin D cables to connect the output of the XTM to the main and option inputs of a CM series monitor (CM-8E recommended). Note that the CM-8E provides a spare input which may be routed through the XTM's high band terminal block.
5. Terminal blocks are also provided to allow wiring to other monitors that have differing pinouts. All crossover outputs are balanced. Use two conductor shielded cable to minimize ground loops and hum.
6. Crossover outputs to power amplifier inputs: Use the terminal blocks provided to wire to traditional amplifiers directly. All crossover outputs are balanced. Use two conductor shielded cable to minimize ground loops and hum. Connect each of the crossover channel outputs to the appropriate amplifier input.
7. DB25 connectors are available on the back plane to make installation quick and easy. Alternatively, terminal blocks allow the use of stripped and tinned wire. They are pluggable for easy service and troubleshooting.

Screen and Horn EQs:

Generally, all six dipswitches should be "On".

In some cinemas, the left and right speakers are mounted outside the screen area. In this case, turn the left and right screen EQ switches to "Off".

Some high frequency horns are very flat to 20kHz. In this case, you may want to turn the horn EQ switches to "Off".

The screen and horn equalizers each add a shelving high pass filter boosting 7kHz by 5dB and 20kHz by 8dB. The combination of horn and screen EQ results in about 16dB boost at 20kHz.

Using a Real Time Analyzer and feeding a pink noise signal from the cinema processor, set the appropriate trimpots for a flat response around the crossover frequency and a total SPL level of 85dB on each of the front three channels. There should be enough range in the output pots to allow setting the amplifier gains between 50 to 100% of maximum.

Set the NORMAL/BYPASS switch to BYPASS.

The Bypass Crossover is fixed at about 430Hz with no time delay. It combines the left, center and right signals and then feeds the center output only.

Using a Real Time Analyzer and feeding pink noise from the center channel of the cinema processor, set the bypass levels for flat response around 400 to 500Hz and SPL level of 85dB.

Return the BYPASS/NORMAL switch to NORMAL.

If the mode is set to triamp, press biamp since the XTM-300 only supports biamp. A warning about selecting an appropriate speaker from the library will appear.

Clicking on the "Default Biamp" button will bring up a Speaker Library.

In the speaker library window, use the dropdown menu to select a particular speaker from the speaker library.

You may load channels by checking the boxes in the library window. When you have selected the channels you want, click "OK" to close the "Speaker Library" window. At this time, the settings you selected are loaded into the XTD-680 and will be reflected in the display and the data at the bottom of the display. You may un-mute the system and audio should be present. This would be a good time to do a Disconnect and select "Save". After doing a Disconnect/ Save, the XTM-300 should be power cycled. When the unit comes back on, it should be ready for use with the speaker crossover settings you saved.
