1. OVERVIEW

1.1 Introduction

The MicroDAC IV Configuration Software allows for complete setup and control of the three preset

adaptive filters and four configurable filters, each consisting of up to two stages. The software provides an

easy to use, intuitive interface for configuring the filter settings and transferring them to the MicroDAC IV.

The Configuration Software provides:

• Choice of two stages within each filter for a total of 3600 taps

• Graphical representation of the actual audio path through the digital filters

• Configurable filter tap distribution between adaptive filter stages

• 13 different filter types to choose from

• Selectable Input Limiter, Lowpass Filter, Highpass Filter, and Output Automatic Gain Control

(AGC) for each filter setup

• Storable configuration settings for later recall and use

• Automatic COM Port detection when transferring filter to the MicroDAC IV

• Front panel locking utility to protect accidental front panel switch changes

• Online help for quick and easy access

Each filter can be configured in a Mono Single (one stage), Mono Series (two stages in series), or Stereo-

Linked (two stages in parallel) mode. The stages within each filter can be independently selected from

one of the following filter types:

• One Channel Adaptive Filter

• Two Channel Adaptive Filter (first stage in Mono modes only)

• Lowpass Filter

• Highpass Filter

• Bandpass Filter

• Bandstop Filter

• Comb Filter

• Notch Filter

• Slot Filter

• 20 Band Graphic Equalizer

• Spectral Graphic Equalizer

• Pass Thru Filter (digital bypass)

Floating-point format coefficient text files can be imported as well.

A description of each filter type, its application and a definition of the control parameters can be found in

the following sections.
