FIR-DRIVE
Sound System Processor
Key Features:
• 116 dB dynamic range
• 2 analog inputs, 6 analog outputs
• 2 digital AES/EBU inputs
• FIR-DRIVE
• TEMP limiter
• Configuration via IRIS-Net
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 con-
figuration 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 pa-
rameters are available on the front panel. Up to 90 presets (60 factory pre-
sets 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 configura-
tion 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 Electro-
Voice Speaker Settings. Please refer to the Dx46 owner‘s manual and IRIS-
Net documentation for more details.
