Active Loudspeaker Crossovers from Danville

The dspInstrument is a general DSP instrument offering two audio channels, digital I/O and an RS-232 and USB interface. It is well suited for small quality control systems and test cells, automatic level controls, audio limiters, signal splitters and test generators.


The dspInstrument digitises two channels of audio, executes DSP algorithms (filtering, signal generation, detection, etc.), and converts the signal back to audio. In addition, the RS-232 and/or USB interface is provided for control, detection and reprogramming the DSP-9600.

The two audio channels can be configured as either 600 Ohm balanced or signal ended circuits. Digital I/O and an audible alarm are also available for test cell or monitoring applications.

Example Application
Retail stores often wish to provide background music through their PA systems. A CD changer could be used to provide the source material but there is a catch: Music levels can vary as much as 15dB from track to track and certainly from CD to CD. The DSP-8410 automatically adjusts the level so that each song is played at the same volume.
