By removing the strapping, the detector input can be separated from the signal input for special pro- cessing applications. This gain reduction would cause the perceived image of any sound spread between the two channels to move toward the side which had not been compressed, because the spread signal would be momen- tarily softer in the compressed channel.
Limiting also benefits intelligibility by allowing low-level input signals to be reproduced through the system at higher volume.
That is, when a phone plug is inserted, the detector input is no longer connected in parallel with the audio input.
Never remove the cover. De-Essing To apply de-essing to vocals i. Rear Panel [ 3E? To compress a live mix or to protect loudspeakers, connect the XT be- v: Depending on the THRESHOLD setting, lower level fundamentals or harmonics will not cause compression, and the program is not subject to the phase shift nor- mally caused by program equalization.
For a stereo sound-reinforcement system, stereo strapping cables should be run between janual XTs in each band low-low, mid- mid, etc. Live As the colors of the wires in the mains lead of dx apparatus may not correspond with the colored markings identifying the terminals in your plug, proceed as follows: This symbol, wherever it appears, alerts you to the presence of uninsulated dvx voltage inside the enclosure — voltage that may be sufficient manul constitute a risk of shock.
Threshold and compression ratios are adjustable over a wide range, so virtually any line level signal can be processed effectively.
Also, do not remove the cover without first disconnecting the unit from the mains supply. The detectors of Two Model X’s can be coupled so that stereo janual are compressed with stable imaging, by means of a simple patch cable between the two units.
Program-dependent attack and release times assure natural sound without the need for con- tinuous manual adjustments. Such sources can be balanced or unbalanced — this is no problem for the 1 60XT.
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. This will not damage the unit, but may increase distortion. Full text of ” DBX: Those fre- quencies passed by the filter are subject to compression or at least they are subject to considerably more compression than those frequencies out- side the passband.
Microphones and bass guitars, like guitars, typically have low-level out- puts. The stereo coupling can be disengaged instantly by a front panel pushbutton. Be sure to verify both the actual line voltage and the voltage for which your Model X was wired, as indicated on the rear panel of your unit.
Plug in the AC power cable to power On the unit. However, gentle tapping of a drumstick or brushing of the cymbal will not be held back. Hard-Knee Compression Curve Figure 3: Turn Off all equipment before making any connections. Instead a DC voltage controls all functions which eliminates any possibility of potentiometer noise as the con- trols age. In hard-knee compression mode, the threshold is defined as that point above which the output level no longer changes on a 1: The wire that is colored blue must be connected to the terminal that is marked with the letter N or colored black; The wire that is colored brown must be connected to the terminal that is marked with the letter L or colored red.
However, it will generally be found that large amounts of compression are more audible in a mixed stereo program than they might be on the separate tracks that were mixed to cre- ate the program.
Multi-way speaker systems If a single compressor is to be used with a multi-way speaker system i. If multi-way loudspeakers with low-level electronic crossovers are used, the XT s should go after the crossover s. This will provide accurate processing for a stereo programming.

Often, a prob- lem is relatively simple and can be quickly fixed after telephone consult- ation. 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. 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.
Our phone number is listed on the inside of the front cover. Ensure that all terminals are securely tightened and that there are no loose strands of wire.
Verify that the 1 60XT package contains the following: The master 1 60XT will now respond to the combined inputs 160dt the XTs. Mark the package with the name of the shipper, and with these words in red: In the studio, the 1 60XT can be used on everything from vocals to percussion.
Raising a signal out of a mix Since reducing dynamic range increases the average signal level by a small amount, a single track can be raised out of a mix by boosting its level slightly and dvx compression. In the latter case, the signals will most likely be unbalanced. This can be avoided by linking the two compressors in such a way that both channels receive the same amount of compression.
Dvx more specific installation information, refer to Installation Considera- tions, page As a general rule, the compressors should be as close to the amplifiers as possible in the signal chain.
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. Pre-emphasis for broadcast applications By inserting a pre-emphasis filter network in the detector path of a XT processing pre-emphasized audio, higher levels dbbx be run within the headroom limitations of the broadcast chain. The Registration Card enables msnual to inform you of 160st applications and performance improvements that are developed, and it helps us re- spond promptly to claims under warranty without having to request a copy of your bill of sale or other proof of purchase.
These features make the Model X compatible with the operating levels of virtually all professional sound and creative audio equipment. In all cases, you are responsible for trans- portation charges to the factory, dbx will pay return shipping if the unit is still under warranty.
Connection to an inappropriate power source may result in extensive damage which is not covered by the warranty.
