This application note will study how miniDSP products can be combined to build a processed stereo three way or four way crossover configuration. If you are new to the concept of multi-way DSP processed loudspeakers, please have a read at our Digital Crossovers section first. In three or four way stereo crossover configuration, a minimum of 2 x inputs by 6 outputs (3way) or 8 outputs (4way) will be required. The following application note will therefore propose two options:
If your application only requires analog input, analog output, miniDSP platforms can easily cater your needs for a very affordable solution.
If your configuration requires the option to input a digital input (SPDIF/TOSLINK), your system will require a miniDIGI. The miniDIGI is an SPDIF/TOSLINK input/output interface with embedded Asynchronous Sample Rate Converter (ASRC). The ASRC is a very important element since it allows connectivity to any digital audio source.
For those of you looking for an all digital solution and reusing your existing DAC, the nanoDIGI 2x8 is the product you need.
- Can I use both Digital and Analog outputs together in a stacked miniDIGI/miniDSP configuration? Yes, see our miniDSP plug-in data-sheet for more information on how outputs are doubled up to both analog AND digital out.- Can I link multiple miniDSP + miniDIGI together? Yes, using the miniDIGI un-processed output, one can easily link multiple miniDIGI + miniDSP stack. See manuals for more information.
- Can I connect an external DC supply AND USB together? Yes, they are both surge protected.
- How can I toggle from Analog to Digital input in a miniDSP + miniDIGi configuration? Source selection is available both in software AND hardware using a toggle switch. See our miniDIGI user manual for more information.
