DBX 160XT Single Channel Compressor Limiter

DBX 160XT Single Channel Compressor Limiter

The dbx 160XT is capable of handling a wide range of applications. In the studio, the 160XT can _be used on everything from vocals to percussion. In live sound reinforcement, the 160XT can allow the engineer to get that "fat studio sound" out of the drum kit or provide protection limiting for the speakers. In radio or television broadcast, the 160XT will produce stable voice levels, even with non-professional subjects.

Features:

• XL-type Input and Output Connectors - be­cause the 3-pin XL connector has been recog­nized as the most durable and widely used connector for professional applications.
• Balanced Output - can drive a 600Ω load to +24dBu and provides common-mode rejec­tion of unwanted noise in the audio path such as RF and 60Hz components.
• True Power Summing - When two 160XT units are slaved together, the RMS energy of the sig­nal presented to the slave unit is summed with the RMS energy of the signal presented to the master unit to prevent phase cancella­tion of the two signals from causing unmusi­cal compressor action. Note: a 160X unit can also be used with the same results as long as the 160XT is used as the master unit.
• Input Ground-Lift Switch - for isolation be­tween shield ground and signal ground. Use­ful when troubleshooting hum (AC line interference).
• OVER EASy® /Hard Knee Selection - allows selection between our famous Over Easy com­pression curve and the classic "Hard Knee" curve popularized by the original dbx 160, 161 and 162.
• True RMS Level Detection - senses the power in the program in a musical manner, much as the ear does, giving results superior to peak or average detection.
• Hardwire System Bypass Switch -allows the audio to pass even if the unit is unplugged, and is also useful for comparing the pro­cessed and unprocessed signal.
• Front Panel Stereo Coupling Switch - couples two 160XTs or a 160XT and a 160X together for stereo operation at the push of a button.
• 19 Segment Display - for high resolution mon­itoring of True RMS input and output levels.
• 12 Segment Display - indicating GAIN REDUCTION.
• Meter Calibration - input/ output meter cali­bration, so the 160XT can be used in a variety of situations where the "O" reference is not consistent.
• ¼" Input and Output Connectors - we kept the 1/4" phone jacks from the 160X, with the output capable of driving its own additional 600Ω load (single-ended) in addition to any load at the XL output.
• Detector Input -useful for special applications including frequency conscious compression in which an external equalizer is used.
• DC-controlled Parameters -the signal does not pass thru any of the parameter controls. Instead a DC voltage controls all functions which eliminates any possibility of potenti­ometer noise as the controls age.
