®
• 4 independent channels of operation, stereo linkable
in two pairs.
• PeakStopPlus™ limiting control for setting maximum
allowable level regardless of compressor settings.
• Switchable OverEasy® or hard-knee compression.
• Selectable Auto (classic dbx) or manual (variable
Attack and Release) compression
• Differentially balanced gold-plated XLR and 1/4”
inputs and outputs.
• True RMS level detection
• Precision metering of input level, output level, and
gain reduction
• Dual True stereo or quad mono operation
• Switchable +4dBu or -10dBV operation per channel
In today’s recording and sound reinforcement environments, the need for multiple channels of high quality, easy to
use compression is growing rapidly. The new dbx 1046 is designed to provide the audio professional with just that:
4 channels of great sounding dbx compression for a variety of applications. Incorporating the industry standard dbx
designs and the latest available manufacturing techniques, the dbx 1046 provides pristine sonic quality with that clas-
sic dbx sound.
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
PeakStopPlus™ is ideal for protecting your system from the oppressive peaks that can take out valuable drivers in
your sound reinforcement rig or studio monitors.
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 dbx160.
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 vir-
tually 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 dbx1046 is for you.
