WORK WD 421 Audio Splitter 2 in & 2 out

Signal distributor. 1 stereo input / 4 stereo outputs or 1 mono input / 8 mono outputs

This audio distributor is very useful to supply several audio devices with only one audio source. Its 2 operating modes allow to work with mono or stereo signals. Output level can be controlled independently.

WD 421 adapts itself to work with different impedances, ensuring that output signal level is at least equal to input signal level. It avoids any undesired attenuation and features a LED vumeter to visualize the input signal level.

Today?s venues face a growing need to provide a multiplicity of audio feeds
from presentations, conferences, orchestral performances and lectures. The
advent of digital broadcasting, the growth of webcasts and direct-to-CD
archiving highlight the deficiencies in audio splitting systems more than ever
before. Whether the final product is a broadcast feed or CD sales of an unrepeatable
lecture, performance or event, end-users? expectations of audio quality are
higher than ever.With these requirements in mind, ARX has developed the
MSX 8 Active Microphone/Line Splitter to deliver the performance required by
today?s standards of audio production. Active microphone and line splitting has
a number of benefits over passive splitters: primarily these are improved sound
quality, noise figures comparable to the best microphone inputs, and increased
resistance to RFI. All of which translate into superb audio quality for your clients.
About the MSX 8
The MSX 8 consists of two channels of actively buffered ultra low noise Microphone/
Line Splitter. Each of these channels has four electronically Balanced splits ? two
on the rear panel, plus two more on the front panel. All four output splits have the
option of transformer balancing if so specified.Each channel has a ?20 dB pad switch
plus silently switchable 48V Phantom power with indicator LED.Gain through the MSX 8
can be set individually by the small DIP switches on the rear of each channel, from 0dB
through to +40 dB in 10 dB stepsA ?Link? switch links Channel 1 to Channel 2, providing
an ultimate maximum of 8 Outputs from a single input. An indicator LED shows when this
is active. A Clip LED indicates imminent signal overload through the channel, and a
numbered marker panel on the front provides a space where individual channel connections
can be noted.For remote or mobile applications a 5 pin DIN connector on the rear panel
provides an access point to connect a 12V DC power supply
Inside Information
Internally, powerful RF input filtering removes both common mode and differential interference
at ultrasonic frequencies and above. High CMRR is achieved by the use of precision components
throughout.Advanced user options include internally jumper linking Inputs to Main outputs, and
Ground lifting Output Pins 1as required.
Internal Power Supply
The MSX 8 has a low noise transformer based power supply to obtain the maximum benefit from
the ultra low noise design of the splitter circuitry.
Summing up, the feature packed MSX 8 is the answer wherever transparent signal buffering and
routing is required.

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.

• Four independent channels of operation, stereo linkable in two pairs
• PeakStopPlus™ limiting control for setting maximum allowable level regardless of compressor settings
• Independent Threshold and ratio controls
• Switchable OverEasy® or Hard Knee compression
• Classic dbx® 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

DBX 2215 Dual 15-Band Graphic Equalizer with Noise Reduction

 It's amazing. One little button. So much effect. dbx? Type III? Noise Reduction is an entirely new concept... virtually instantaneous encode/decode within the circuitry of the box. We started out to build the finest EQs possible, boxes with the heritage and performance to rival our famous 30 Series EQs. And to no one's surprise they came out awfully darn good. (Ask to see the Audio Precision plots compared to the competition.) But then, Roger (our chief engineer, a nice guy, as far as engineers go) got the crazy idea of putting this new noise reduction stuff in the box. We listened to it and were amazed. The EQs sounded great without it but with it the performance was nothing short of incredible. Check it out yourself and see.

But hey, Roger wasn't about to stop there. PeakPlus? Limiter. Who knows more about limiting than the folks at dbx; nobody... that's who. So when the guys were developing this new series of EQs they wanted something that would be unique to these EQs. That's when Roger got another one of his bright ideas and said "I bet they'll work a lot better if there's a cool limiter built in." Next thing you know, all the guys are in the studio amazed at the new limiter Roger had designed specially for the 20 Series. Once again, hearing is believing... With a threshold range of 0dbu to plus 20dbu, the patent-pending PeakPlus limiter is designed to tame your program material from the subtlest nuances to the rowdiest hits. Also, the four stage LED ladder gives you a great visual indication as to what the limiter is doing.

20 Series EQs. You used to have to settle for second best in a reasonably priced EQ but not any more. With the new 20 Series from dbx Professional Products you get a great EQ circuit, a graceful yet powerful limiter and the revolutionary new design of the Type III Noise Reduction. Check out the dbx 20 Series graphic EQs at your pro audio outfitter. You'll see, with the 20 Series EQs you get MORE!!!
