Also, do not remove the cover without first disconnecting the unit from the mains supply. If you are using a Stereo phone plug manusl the next device, tie the Ring and Sleeve together, and connect the sleeve to the wire’s Shield. 160xr XT is tested, burned in and calibrated at the factory and 160xh require no internal adjustment of any type throughout the life of the unit. Live As the colors dx the wires in the mains lead of this apparatus may not correspond with the colored markings identifying the terminals in your plug, proceed as follows: The equalization in the de- tector circuit means that the compressor is not triggered as readily by a loud tom-tom beat as by an equally loud cymbal crash.

Using your EQ to reduce feedback in live settings. Search the history of over billion web pages on the Internet. Power consumption is low. We have added a few new features to the dbx Model XT while main- taining the performance and ease of operation of its predecessor, the dbx X.


Remember mabual, as with any amplifier, excessive gain may lead to output clipping of high level signals. Preventing tape saturation With programs of widely varying levels, compression can prevent record- ing levels from saturating tape tracks see Frequency-weighted compres- sion, page The XT will catch it, and hold it as a constant tone so you can adjust your EQ to minimize it.


Assuming the tom-tom is a lower frequency instrument and can be better tolerated by the tape, it has less need for compression.

All trademarks are property of their respective companies. This gain reduction would cause the perceived image of any sound spread between the two channels to mwnual toward the side which had not been compressed, because the spread signal would be momen- tarily softer in the compressed channel. Nonetheless, be sure to examine the unit and the carton for any signs of damage that may have occurred during shipping.

To compress a live mix or to protect loudspeakers, connect the XT be- v: Mounting the unit directly over large heat-producing devices such as a vacuum-tube power amplifier may shorten component life and is not rec- ommended. If the XT is wired into a patchbay, never insert a mono phone plug into the patchbay.

Another option is to install an output trans- former, which will allow grounding of either pin 2 or 3 of the XLR-type out- put see page In certain situations, the auxiliary device may need to be inserted in the signal path, not in the detector path.

Know the serial number of your unit — this is printed on a sticker attached to the rear panel. In the latter case, the signals will most likely be unbalanced.

With an equalizer inserted ahead of the detector input but not in the audio paththe equalization settings do not shift the timbre or frequency response of the audio signal. By removing the strapping, the detector input can be separated from the signal input for special pro- cessing applications. Unpack and Inspect the XT package. At a setting of This will provide accurate processing for a stereo programming.

Those fre- quencies passed by the filter are subject to compression or at least manuql are subject to considerably more compression than those frequencies out- side the passband. The XT will then begin to release recover from compression before the loud passage has ended.


Input signals which dbxx be- low this level will pass through the 1 60XT unprocessed except for fixed gain changes directed by the output control. When compressing a stereo program with a pair of XTs, the factors affecting a compression curve and the actual compression ratio and threshold settings, are like those previously covered with reference to single channels of program material.

Microphones and bass guitars, like guitars, typically have low-level out- puts.

If two independent compressors are used to process the stereo program, a loud sound occurring in one channel will cause a gain reduction only in that channel.

The system can then be run at higher levels and will only be dropped back when dam- aging signals are present.

Connection to an inappropriate power source may result in extensive damage which is not covered by the warranty. Frequency-Weighted Compression With this arrangement, raising certain frequencies on the equalizer causes them to be suppressed in the audio signal.

If multi-way loudspeakers with low-level electronic crossovers are used, the XT s should go after the crossover s.

That is, when a phone plug is inserted, the detector input is no longer connected in parallel with the audio input. The stereo coupling can be disengaged instantly by a front panel pushbutton. Note that the XT does not have a power switch. Full text of ” DBX: Ebx inserting an equalizer in the detector path to the XT, it can be made more sensitive to frequencies in the range handled by the sensitive drivers.

Turn Off all equipment before making any connections. Customer Service The Schematic for the XT boards and power supply are provided on the inside back cover.
