The 3632 Compressor is the follow-up to the 3630 Compressor, the most popular dynamics processor ever made. The 3632 Compressor builds on the popular design and features of its predecessor by providing two independent, full-featured compressor/limiters in one compact rack. It delivers superb sonic quality for any application from studio recording to live sound or broadcast.
Manual or Automatic With the push of a button the 3632 Compressor’s attack and release times can be set to engage automatically depending on the source signal. In this mode, the 3632 applies an optimized amount of compression with no extremes. Want full manual control? Again, just push a button and you have free reign over the 3632’s comprehensive range of parameters. The 3632 Compressor can function as either two individual mono processors, or you can stereo-link them to provide true stereo compression.
Guard Your Sound The 3632 Compressor’s Expander/Gate keeps unwanted noise out of your sound. When your signal falls below the threshold you’ve chosen, the Expander/Gate pushes low-level noise down or simply closes the gate depending on the parameters you’ve dialed in. Deny noise access to your audience or your mix!
At the heart of the 3632 Compressor is its VCA (voltage-controlled amplifier), which offers professional-grade performance in terms of distortion, noise, and temperature stability, making everything you hear smooth and consistent.
The 3632 Compressor’s sidechain function on each channel enables you to use it in external effects loops or in other common compressor applications such as ducking: use the sidechain function to trigger compression on a signal when you want it. A second, internal sidechain employs a switchable low-cut filter to help control pumping due to heavy low-frequency content.
With intuitive control layout and bright LED meters that display gain reduction and input/output levels per channel, the 3632 Compressor will give you constant visual feedback. Professional compression is ultimately about the control and delivery of sound, and the 3632 Compressor will make you a master at both.

A cure for compression confusion is here. Quit guessing and anguishing over proper compressor and gate settings. Get on with what is important, your work. Rane has created a compressor gate using high quality log rms detectors and Voltage Controlled Amplifiers (VCAs). The DC 22S combines quality compression and gate functions with simplicity. No more compression headache!
Lets start with what a compressor actually does. No matter how you cut it, this is an automatic volume control... a hand on a control, turning it down and turning it up again. The hand is fast and accurate, but it is just turning a volume control.
When the input signal reaches a level set by the Threshold control, the compressor begins to turn the signal down by an amount determined by the Ratio control. The DC 22S, like most compressors, operates by making the loud signals quieter, but does not make the quiet parts louder. However, by keeping the loud signals under control, the entire system may be turned up when necessary to make the quiet parts louder.
There is more than just a stereo compressor working here. The adjustable Gate is a downward expander, acting like a compressor running in reverse, making the quiet parts quieter. This is valuable in reducing system background noise. The Ratio is fixed at 2:1. When the signal drops below the set Threshold, the Gate Threshold indicator lights and the output level is reduced by 2 dB for every 1 dB the input signal level drops.
When using the DC 22S as a true stereo processor with left and right signals, activate the Link switch. In Link mode, channel 1 becomes the Master and channel 2 the Slave. Gate Threshold, Compression Threshold, Compression Ratio and Output Level are all controlled by channel 1. This ensures that both channels track perfectly, maintaining perfect balance and image. The channels are totally independent with the Link switch off.
The DC 22S offers performance and simplicity not found (until now) in this price range. Designed for the working musician or club system, The DC 22S provides reduced complexity without compromise in audio quality or dependability.
Control Descriptions
A Primer Let’s start with what a compressor actually does. No matter how you cut it, this is an automatic volume control. It is a hand on a knob, turning the volume down and turning it up again. The hand is really quick and really accurate, but it’s just turning a volume control. When the input signal reaches a level set by the COMPRESSOR THRESHOLD control, the compressor begins turning down the signal by an amount determined by the RATIO control. The DC 22S, like most compressors, operates by making the loud signals quieter, but does not make the quiet parts louder. However, by keeping the loud signals under control, the entire system may be turned up when necessary to make the quiet parts louder.
Pre-flight Checklist Before proceeding, it’s a good idea to turn the control knobs to the following positions:
GATE THRESHOLD control fully counterclockwise
COMPRESSOR THRESHOLD fully clockwise
COMPRESSOR RATIO fully counterclockwise
BYPASS switches ACTIVE (out)
OUTPUT LEVEL 0 dB
This renders the DC 22S with no compression, allowing signal through at unity gain. No change occurs with the BYPASS switch in or out.
Input Level Before making any Threshold adjustments, set the ouput level of the previous device so the +4 dBu LED lights occasionally, and the OL LED does not light. Be aware that changes to the Input Level will affect the Thresholds.
Gate Threshold The threshold is the point at which gain adjustment begins. When the input signal is below the threshold, the DC 22S attenuates the signal at a 2:1 ratio, making the quiet parts twice as quiet. When the signal is above the Gate Threshold, the Gate is open, like a straight wire. With a fixed Ratio set to 2:1, this graph shows gain reduction below various Gate Thresholds at -20 dBu, -30 dBu, -40 dBu, etc.
Compressor Threshold The threshold is the point at which gain adjustment begins. When the input signal is below the threshold, the Compressor section acts like a straight wire. When the signal is loud enough to cross the Compressor Threshold, the compressor is active and turns the volume down. Various Threshold points are illustrated below. How much it gets turned down is determined by the RATIO control ( this graph shows a Ratio set at 2:1). With the Ratio set to 8, the DC 22S acts as a Limiter. This graph shows Limiter gain reduction above various Compressor Thresholds at 10 dBu, 0 dBu, -10 dBu, etc.
Ratio Once the Threshold is exceeded, the increase in output compared to the input signal increase depends on the RATIO setting. An ordinary preamp set for unity gain or a straight wire has a ratio of 1:1, that is, the output level tracks the input level perfectly. A 2 dB change at the input produces a 2 dB change at the output. For a 10:1 Ratio, a 10 dB blast at the input would rise only 1 dB at the output -- heavy compression. Kinder, gentler ratios are in the 2:1 to 3:1 range. Limiting, with no increase in signal above the Threshold, occurs at 8:1. The next graph illustrates various Ratios with the Threshold at -40 dBu and Ratios of 1:1, 1.2:1, 1.5:1, etc. Vertical axis = output level, horizontal axis = input level.
Limiting A limiter is a special form of compressor set up especially to reduce peaks for overload protection. In other words, it’s a compressor with a maximum ratio. A compressor is used to change the dynamics for purposes of aesthetics, intelligibility, recording or broadcast limitations. Once the threshold of a limiter is reached, no more signal increase is allowed. The DC 22S acts as a limiter when set at a very high ratio of 10:1.
Linking In Stereo When using the DC 22S as a true stereo processor, with left signal in Channel 1 and right signal in Channel 2, it is recommended to turn the LINK switch on to prevent large balance and image shifts. While LINKed, both Channels attenuate by exactly the same amount when either Compressor works, maintaining correct stereo imaging. Only Channel 1's controls are active, Channel 2 becomes the slave.
Compressor/Limiter Since its introduction in the mid 1970's, the dbx 160 series has been the world's most popular line of audio compressors. After the classic 160 (which is still used daily in many world class studios), came the 165, the 160X and the 160XT. The 160X/XT were the models that truly became the industry standard. Solid construction, fool proof operation, great sound, at-a-glance metering and a bulletproof output stage all contributed to its popularity with musicians, recording studios, consultants and installers, and broadcast media production people alike.
The dbx 160A is a legendary dbx 160 family of compressor/limiters. The same classic sound, easy set-up and no compromise metering is now married to an improved signal path and stronger chassis design. The result is industry standard compressor/limiter which is digital-ready and road tough.
Featuring switch-selectable OverEasy and Hard Knee compression curves along with extremely wide-ranging threshold, ratio and output controls, the dbx 160A is up to any task. True RMS level detection provides the most natural-sounding dynamics processing available, from subtle compression to "brick wall" peak limiting. Choose low ratios and OverEasy compression to transparently smooth out fluctuating vocal and instrumental levels. Or use the 160A's Hard Knee compression and high ratios (up to and beyond :1 and over 60dB gain reduction) for bombproof protection against overload distortion in digital recording, P.A. systems and broadcast signals. The 160A is fully compatible with +4/-10dB and balanced/ unbalanced systems, and its electronically balanced output stage is an outstanding line driver for long cable runs (an output transformer is optional). The 19-segment, switchable input/ output LED metering can be easily calibrated to any operating level. 12-segment gain reduction LEDs provide precise analysis at a glance.
The dbx 160A's unique "INFINITY +" inverse-compression mode actually decreases the audio output level below unity gain when the input exceeds threshold, a real lifesaver for correcting overbearing vocal choruses and controlling runaway house mix levels. A detector input can be used with an equalizer for de-essing sibilant vocals and selectively smoothing out boomy notes on acoustic guitar and bass. And two 160As can be stereo-coupled to process an entire mix or instruments mic'd in stereo, without shifting the left/right image. Its musical sound, easy operation and unequaled versatility made the original dbx 160 a world standard. The 160A follows that tradition, while meeting the challenges of a digital world.ent in the mix, or overall characteristics of 4 independent signals or control the gain leveling on a couple of stereo pairs, the dbx 160A is for you.

After producing the world's most renown series of compressors, the task of producing a new compressor worthy of our reputation would be daunting for most engineers. Not for dbx. Our engineers know audio like no one else in the world. Now the fruits of their talents are available to you in the form of the 1066 Stereo Compressor/Limiter/Gate.
Want to instantly add that classic dbx response to your mix? It's there at the touch of the "Auto" button. Or use the independent Attack and Release controls to tailor the 1066 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 PeakStopPlus 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 1066 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 1066 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 1066 perform better than compressors selling for hundreds more.
State-of-the-technology VCA's, meticulous component selection, and scrupulous testing procedures are just a few more reasons that the new dbx 1066 is the latest in a long line of pedigreed dbx signal processors.

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 classic 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 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.
