2 Introduction

Thank you for purchasing the Electro-Voice Dx46 Digital Signal Processor. The Dx46 Digital System Processor is a
universal two-input, six-output digital signal processor with the flexibility of configuration to handle a multitude of
audio system needs and applications; installed sound, house of worship, convention & meeting facilities, concert
touring, club, portable sound reinforcement and more.
CAUTION: To achieve optimum performance and guard against damage to the processor, your sound
system or yourself, please read, understand and follow all of the directions contained in
this Owner's Manual. Failure to do so may result in improper performance, loss or injury.

2.1 Dx46 Features

The internal signal processing structure can be configured as 2-way stereo + full-range, 3-way stereo, 4-way mono
+ full-range, 5-way mono + full range, 3-way stereo with a mono sub + full-range, 4-way stereo with mono sub and
low frequency and finally as a freely assignable 2 x 6 matrix router.
The Dx46 replaces entire racks of signal processors previously needed to properly configure and control sound re-
inforcement systems with a single Dual-Core DSP processor. The substantial advantages of the Dx46 over discrete
signal processing racks include:
• 24-bit, 48 kHz digital signal path
• No patch cables to fail or add noise
• Optimal gain structure throughout all stages of signal processing; no gain matching from processor to processor.
• Recallable factory and user presets; instant system reconfiguration for differing applications and performances.
• Easy, intuitive operation and editing with a PC and IRIS-Net
FIR-DRIVE
The Dx46 includes Finite Impulse Response (FIR) filters at each output for loudspeaker linearization. Using FIR filters
has the following advantages, compared to using IIR filters (e.g. Bessel, Butterworth,...).:
• extremely linear frequency response
• very high stop-band attenuation
• linear phase systems
To sum up, FIR-DRIVE allows the linearization of frequency and phase of your Electro-Voice loudspeakers. Activat-
ing FIR-DRIVE is as easy as loading a FIR Speaker Setting in the output channel of the Dx46. The IRIS-Net software
is used for loading Speaker Settings, and lots of Electro-Voice FIR Speaker Settings are included. Please refer to
the documentation of IRIS-Net for more details about using Speaker Settings.
Each Dx46 Digital System Processor includes the following signal processing blocks:
