Not according to the published specs: http://www.theaudioarchive.com/TAA_Tape_Studer_A820.htm # Frequency Response (+/- 1 dB) * 30 ips - 60 - 20,000 Hz * 15 ips - 30 - 18,000 Hz * 7.5 ips - 30 - 12,000 Hz * 3.75 ips - 30 - 8,000 Hz This machine, the A820 is a professional studio stereo recorder using 1/2 tape. Most tracking was done on 2" machine, typically with 24 tracks. If you do the math, each track on the A820 is a 1/4 inch. On a 2" machine, they are 1/12". Less tape nearly always means less quality (snr, frequency response, etc.) And even if the tape machine could do 30kHz, the mics, preamps, mixers, etc can't. Wishing that there is tons of masters with significant signal over 20kHz doesn't make it so. With modern stuff, there is tons of ability to record high frequencies, but today's market is mp3s, audio quality is not important. -- Pat Farrell http://www.pfarrell.com/ _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
