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.
Audio signal distributor with 2 inputs and 8 outputs. Two operating modes: 1 stereo input with 4 stereo outputs. 1 mono input with 8 mono outputs. Adjusting Output level. Balanced LINK output for interconnecting several units. Individual gain control of each 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!!!

A 4-channel modular passive Line level splitter system. Each module of the PRM-LS has 4 channels, comprising of one XLR input, one parallel XLR output and 2-balanced XLR transformer isolated outputs. |

EC-2 Superb Audio Quality Active microphone and line signal splitting has a number of benefits over using passive splitters: primarily these are improved sound quality, noise figures comparable to the best microphone inputs, and increased resistance to RFI. About the MSX 32 With these benefits in mind, the ARX MSX 32 Active Microphone/Line Splitter has been developed to deliver the performance required by the increasing complexity of today?s standards of audio production. The MSX 32 consists of eight channels of actively buffered ultra low noise Microphone/Line Splitter. Each of these channels has four electronically Balanced splits ? two outputs on the rear panel for Main and Monitor, plus two more output splits on the front panel. All 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. A PFL switch and 6 LED metering enables each channel to be easily checked with headphones for signal monitoring, and also for line tracing when troubleshooting. Gain through the MSX 32 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 each channel to the previous one, providing an ultimate maximum of 32 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. Number stickers are provided to give each channel an individual number for up to 40 channels when multiple MSX32s are being used.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 1 as required. Internal Power Supply The MSX 32?s internal toroidal transformer based power supply is triple shielded to get the maximum benefit from the ultra low noise design of the splitter circuitry. An illuminated power switch on the front panel provides visual confirmation of AC power connection to the unit.The headphone output and the 6 LED PFL metering are both mounted on the right hand side of the front panel. Rear panel connectors enable this function to be linked when using multiple MSX 32 units. To sum up, this feature packed two RU device is the answer wherever transparent signal buffering and routing is required.

The secret to making speakers sound great lies with the crossover you use. With the dbx® 234xs Crossover you'll get great performance, ultra low-noise, rugged reliability and four decades of dbx knowledge and expertise in building the world's finest processors. The 234xs uses precision filters to separate the audio signal and direct the correct frequencies to your loudspeaker drivers. By directing only the specific frequency bands to each speaker driver the 234xs leaves your amplifiers free to use their full power on the usable signal eliminating distortion and giving your PA system a cleaner and better sound.
The dbx 234xs is a dual channel crossover with all the features you would expect from a professional product. It features Linkwitz-Riley 24dB per octave filters, independent output gain controls for level matching, output phase inversion, 40 Hz low cut filter, and optional mono summing of the low frequency (subwoofer) output.
