PROCESSOR USE: General Guidelines and Preset Description

IMPORTANT! Please read before operating this Digital Signal Processor with your audio system.

General Use Guidelines for Freely-Configurable DSP

This is a professional level DSP product that allows the user to produce virtually unlimited signal processor variations and configurations. Because of the infinite configuration possibilities of digital signal processing, it is possible to create configurations that may result in unwanted signals or uncontrollable output.

The Signal Manager software has no way of knowing if the DSP configuration you have designed will produce the results you intend. You can create signal loops in a configuration that may oscillate and damage your sound system if applied to the unit. When applying an untested configuration or when designing or experimenting with this unit, it is a very good idea to turn down the amplifier’s physical gain controls. That way, you won’t damage your speakers or create very loud sounds if you apply a configu- ration that doesn’t do what you thought it would.

As a general rule, DO NOT CREATE SIGNAL LOOPS! Do not mix the output of a DSP object back into its own input! There is nothing useful to achieve by doing this, you will only create an oscillator that could damage your speakers. Also, USE THE SINE AND NOISE GENERATOR OBJECTS WITH GREAT CAUTION! These functions produce signals that can harm your speakers. Start with lowered gain settings. If you don’t hear a signal when you think you should, DO NOT INCREASE THE GAIN!!! If the signal isn’t audible at lower levels, there is something else wrong. Turning up the gain to full exposes you and your system to the possibility that some loose connection somewhere will suddenly send a full-amplitude signal through your sound system.

Like all freely configurable signal processing tools, this DSP will do what the configuration your design tells it to do, which may not be what you expect it to do, so use caution.

Factory Presets

NOTE! The factory setting for all eight Preset memories is wire- through. Signals are passed from input to output without any processing. Each Processor must be configured as desired by the user. You may select configurations from the sample files (*.cfg) within Signal Manager or create your own.
