DBMax is a Level Maximizer and Audio Enhancement processor for use in digital transmission, linking, webcast and radio STL applications. High resolution and high sample rate processing prevents unwanted distortion and listening fatigue from being generated, artifacts often associated with comparable processors. The 5-band section in DBMax can be combined with Automatic Gain Control, Dynamic and Static Stereo Enhancement, Dynamic and Static Eq and other tools for maximizing audio impact and creating a signature sound. Balanced and unbalanced AES/EBU I/O is standard, and outputs are always active. Sample rate conversion can be invoked when using digital inputs. Analog I/O is standard and outputs are always active. The 24 bit converters are scaled in the analog domain, with scaling under preset control, to minimize noise and maximize headroom under all operating conditions. DBMax can be remotely controlled using GPI or RS485 serial inputs.
Main Features
Maximum Level Maintain maximum level and simultaneously eliminate overshoots. Maximum efficiency: 5-band compression Limiting: Sample accurate, distortion reduced Limiter Multi Slope: Add gain at mid-levels without squashing the transients Optimum Quality The DBMAX employ precise calculations at a full processing rate, in order to keep aliasing distortion low and audio bandwidth high.
Audio quality has been our primary concern when designing the DBMax ? hence you can even cascade several units without any sonic penalties. Bandwidth: Processing at up to 48kHz sample rate for 24kHz audio Resolution: Processing of all 24bits of an AES/EBU Digital signal A/D-D/A converters: 24bit resolution with analog pre-scaling Output Formats AES/EBU, S/PDIF and Analog outputs are all active simultaneously. Digital outputs may be dithered to resolutions between 8 and 24bits. Analog and Digital outputs may have emphasis applied individually. Gain Transfer Example of gain transfer and parameters using DBMax. Presets The DBMax comes loaded with 60 presets for a variety of different applications. DBMax Internal Structure Four selectable Insert algorithms surround the multi-band structure. The digital output fader may be remotely set via voltage control. | L-1102

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.
