Hi thanks for reading this.
I am looking for any information on this real time Audio Spectrum Analyser
Model DN60 & matching add on Reverberation Analyser RT60. It has 30x16 LED
bargraph matrix display covering 25Hz-20KHz & a 15 or 30dB display range, with
slow med fast response, avg/pk, 3 memories, etc.
It takes Line/Mic XLR in etc. & has white noise O/P. It has a plug in reverb
unit to measure echo delay & also a printer option.
I have got the unit going repairing display damage & recalibrated as far as I
can, but I would like more information on, usage, specs, & circuits etc.
I have so far worked out the Pink noise source circuit & added White (flat)
& Red (-6dB/O) noise options.
I have also made up an electret condenser mic to use as the calibrated mic
(should be their AT 1), but this seems to lack the very top HF, 16-20KHz.
Any information would be greatly appreciated.
/QSL
