Section 1: Introduction- DSP-3 General Use Guidelines

IMPORTANT! Pleas read before operating the DSP-3 with your audio system.

The DSP-3 is a professional level DSP product that allows the user to produce virtually unlimited signal processor varia- tions and configurations. Because of the infinite configura- tion possibilities of digital signal processing and the DSP-3, it is possible to create configurations that may result in unwanted signals or uncontrollable output

Signal Manager has no way of knowing if the DSP configu- ration you have designed will produce the results you intend to produce. You can create signal loops in your configuration that may oscillate and you may damage your sound system if you apply such configurations to the DSP-3. When applying an untested configuration or when designing or experiment- ing with the DSP-3, 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 configuration 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 that, you will only create an oscillator that could damage you speakers. Also, USE THE SINE AND NOISE GENERATOR OBJECTS WITH GREAT CAU- TION! These objects produce signals that can harm your speakers. Turn down the gain. 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 some- where will suddenly send a full-amplitude signal through your sound system.

Like all freely configurable signal processing tools, the DSP- 3 will do what the configuration you design tells it to do, which may not be what you expect it to do, so use caution.
