The 1046 provides 4 channels of smooth classic dbx OverEasy¨ or Hard Knee compression that are perfectly suited for use on individual tracks of your multitrack recorder, and in virtually all applications the separate channels can be individually interfaced and used for entirely independent purposes. Additionally the newly developed PeakStopPlusª is ideal for protecting your system from the oppressive peaks that can take out valuable drivers in your sound reinforcement rig or studio monitors.
Want to instantly add that classic dbx response to your mix? The continuously variable independent Attack and Release controls allow you to tailor the 1046 to your specific needs. Unwanted frequencies or mic bleed in the signal path? Frequency dependent gain control is a snap to set up and execute with our Side Chain External button (SC Ext). Use the Side Chain Monitor button (SC Mon) and your favorite EQ to dial in the specific frequencies you want to trigger the device. As has become our standard, the contour switch allows entire mixes to be easily smoothed with soft compression while keeping low frequencies from punching holes in the overall mix. Selectable input and output metering allow you to make sure that everything is matched up level-wise, maximizing your signal-to-noise ratio.
For overall speaker protection, our new PeakStopPlusª does all previous circuits one better. With a new design, the PeakStopPlus represses those unwanted transients from blowing your drivers while minimizing the distortion common to many other "hard" limiters. Selectable Hard-Knee or OverEasy¨ characteristics make the 1066 ideal for your gain control needs, whether you're looking for "heavy" almost-special-effects compression or soft, smooth gain leveling. New lightpipe technology replaces standard LED's found on most other units, making the 1066 both very easy to read and much easier to operate.
In the studio, broadcast facility or on the road with a P.A. system, the 1046 is designed for perfectly simple operation. The 1066 allows you to eliminate unwanted signals, flexibly control overall signal gain and guard your overall mix in dual mono or stereo operation.
At the heart of the 1046 is our new dbx V2 VCA. Developed especially for the 1066, 1046 and other 10 series products to come, this revolutionary VCA boasts superb dynamic range characteristics while maintaining very low distortion and almost immeasurable noise characteristics. The bottom line is this: a new VCA working in conjunction with world class design makes the dbx 1046 perform better than compressors selling for hundreds more.
All four channels have the following controls:
Threshold -
allows you to set the level at which the compressor starts affecting the gain
OverEasy -
allows you to select between soft compression for overall gain control or Hard Knee compression based on the characteristics of the original dbx 160.
Ratio -
allows you to set the slope of gain reduction affecting the signal over the threshold level.
Input/Output Meter -
allows you to set the meter to check the input and output levels for maximum signal-to-noise ratio and best level matching.
Output Gain -
allows you to add make-up gain or to adjust the output level for that channel to match the next device's input gain.
Bypass -
hard wire bypass allows you to hear how the compressor is affecting your signal.
PeakStopPlus -
allows you to set the maximum signal level you want to pass through this channel. While it's virtually impossible to eliminate distortion, the PeakStopPlus circuit does it gracefully and effectively with minimal distortion.
Stereo Link -
allows you to link channels 1&2 and 3&4 for two channels of true stereo compression.
All four channels feature balanced gold plated XLR and 1/4" inputs and outputs, and switchable +4dBu or -10dBV operating level to interface each individual channel with any other device.
So whether you need to control the level, placement in the mix, or overall characteristics of 4 independent signals or control the gain leveling on a couple of stereo pairs, the dbx 1046 is for you.
