The revised DN500 Plus series utilises a new ?THAT?s? chip which features lower distortion, improved dynamic range and faster slew rate. We?ve updated the cosmetics too, bringing them into the new KT ?family look?. The DN500 Plus is our dual compressor / limiter / expander which is characterised by its extremely quiet operation, typically >2dB quieter than any comparable product. This alone has made it a broadcast-industry standard for many years. The two channels are linkable for true stereo operation, and both the compressor and expander sections are fitted with their own sidechain inputs. The DN504 Plus Quad Compressor has enjoyed hugely increased popularity in recent years, due to the ever expanding use of in-ear monitor systems. This is because the unit can be configured into two stereo pairs, has all the superlative audio performance of the DN500 Plus, and fits two sets of stereo compression into just one rack space. This configuration also makes it extremely cost effective. DN514 Plus has become one of the industry standard multi-gate devices for both recording and live applications. Providing the same superb audio performance as its other 500 Plus – series, DN514 Plus packs four channels of frequency conscious gating into just 1RU. This provides a significant operational advantage, being able to tailor the operation of each gate to a specific frequency range.
DN500 Plus Dual Compressor / Limiter Expander Overview :
Two channels of full function compression, expansion, limiting and peak clipping in one unit of rack space. Variable knee control for compression styles from hard to easy. Auto attack/release mode for inaudible compression and easy set-up. Manual attack/release mode for creating compression effects. Advanced VCA design for extremely low noise and distortion. Flexible expander section features variable ratio for gentle expansion or hard gating. Separate side chain inputs are provided for compressor and expander sections. A peak limiter with variable threshold and programme related release provides additional protection. Peak clipper eliminates transient overload and tracks limiter threshold for total protection. Additional features include stereo link function, gain reduction meters for both compressor/ expander sections and output level meter. The DN500 Plus is sturdily constructed throughout and complies with standard 19? 1U rack mounting requirements.

Innovation
The ARX AFTERBURNER? is a unique Multi Mode compressor/limiter designed for use in any professional audio dynamics control application. Multiple Modes The Afterburner can be set up and used in three different ways: In Two channel mode, it performs as two independent compressor/limiters, with 'industry standard' variable Threshold, Ratio and Output gain. In stereo mode, our New Adaptive Stereo Link circuitry provides increased stereo imaging accuracy when linking both channels as a stereo pair. A single front panel switch puts the Afterburner into its alternative Mono mode, setting it up as a Single channel, Dual Band compressor/limiter, with separate dynamics control of both Low and High frequencies, opening up a whole new range of gain control techniques. Enhance Switch In any mode, the Afterburner features an 'Enhance' switch, which provides frequency restoration to preserve the spectral balance of the audio signal, compensating for the sagging Low and High frequency response of compressed program material. Think of it as a 'smart' loudness control.
Features Switchable Modes - Stereo; Dual Channel Single band; or Single Channel Dual Band (Low and High) Low and High frequency compression in Single Channel mode 'Enhance' switch restores spectral balance of compressed signal New Hard/Soft knee compression switch New Adaptive Stereo Link circuit for accurate stereo imaging New Above/Below Threshold LEDs enable at-a-glance compression confirmation Balanced XLR and Jack Inputs and Outputs Sidechain Insert points Intuitive user-friendly layout Flawless performance
New Above/Below Threshold LEDs enable at-a-glance compression confirmation New Hard or Soft knee compression option New LED metering provides accurate Level status, with separate Gain Reduction metering in easy to read 'wide scale' meters. There is also comprehensive LED indication of all operating functions and status in any mode. Balanced Inputs and Outputs On the rear panel, each channel has true differential Balanced inputs and outputs, on both XLR and TRS jack connectors. As well, each channel has a TRS jack Sidechain access insert point, for applications such as De-essing (when used with an external equalizer such as the ARX Multi Q or EQ 260).Other features include a true Hardwire bypass switch for each channel, and passive RFI filters on the inputs. Universal AC Power AC power range is a universal 100 to 120V or 220 to 240V AC, and is connected to the unit via a removable power lead and standard 3 pin IEC connector, with built-in fuse and voltage change switch. With its smooth compression, intuitive user friendly layout, high density precision circuitry, and extensive user-variable operating parameters, the unique ARX Afterburner is equally at home in Studio, Installation, Broadcast and Sound Reinforcement environments. It can provide great sounding dynamics control effects that are not available with any other device.
