General Description:
The Electro-Voice Dx46 is a digital sound system processor with 2 analog inputs, 2 digital AES/EBU inputs and 6 analog outputs. With high resolution FIR filters, sophisticated speaker protection and a multi level delay concept the Dx46 sets new standards for digital loudspaker processors. FIR-DRIVE provides highly detailed optimization of loudspeaker performance through the use of complex-phase FIR filters and advanced DSP settings. The configuration and operation of the device can be done via the front panel or the IRIS-Net software. For remote configuration and control the Dx46 can be connected via Ethernet or USB. The integrated 2 port ethernet switch allows daisy chain connection of devices. Direct-access buttons for editing DSP parameters are available on the front panel. Up to 90 presets (60 factory presets and 30 programmable user presets) can be used. The integrated FLASH memory allows software or preset update via Ethernet or USB. Five control inputs on the rear panel can be used for recall of presets using external switches or contacts. On the front panel level meters for input and output signals, output gain reduction, limit and clip LEDs, dedicated Mute buttons, output channel function indicators (SUB, LO, MID, HI) and a LCD display (192x32 pixesl) with blue backlight are available. There are 6 preconfigured configurations plus one free configurable full edit (2 in 6 out) configuration available. Three dedicated processing groups (user, array, speakers) are available. For each output 512-tap FIR filters can be used, the PEQ and GEQ use 48 Bit filter algorithms. A look-ahead Peak limiter and TEMP limiter (Thermal Energy Management and Protection) are available. The integrated Signal Generator allows internal generation of pink noise, white noise or sine signal. Every DSP parameter can be locked and / or hidden. The configuration of the ethernet port can be done via IRIS-Net device scan. Using 24 Bit AD/DA converters a dynamic range of 116 dB is reached. A switchable input PAD (-6 dB) can be activated. Configuration is done via IRIS-Net software, the visualization of the system transfer function is possible using ElectroVoice Speaker Settings. Please refer to the Dx46 owner‘s manual and IRISNet documentation for more details.
