Shaping radio today and tomorrow

That was then

In1994, Fostex's D-10 DAT recorder boasted auto record, hands-free editand accurate repeated punch-in recordings. A RAM Scrubbing functionallowed about 1MB of RAM to be used for cueing to an edit point withthe jog/shuttle wheel. The jog/shuttle feature allowed the user toclearly hear the audio material during forward and backward play. A10-key pad allowed the user to store and recall as many as 100 cuepoints.

The D-10's control layout was functional. Transport controls werelocated under the cassette tray, including those for auto cuing andsearch operations. A blank search function sought the next unrecordedsection of a tape.

The recorder could record or play as many as 799 program cuts withauto or manual numbering, renumbering and skip programming. The companyeven suggested using a pair of recorders for precise assembly editingprocedures using the universal GPI ports to provide the control betweenthe two machines.

Although DAT recorder's overall design was successful, there were afew minor quirks. A Field Report in the May 1994 issue of Radiomagazine pointed out that a delayed power muting function needed to beadded to avoid the audible pop in the speakers or headphones. Inaddition, to use the RAM scrub feature, the tape needed to be stripedwith A-Time or R-Time. This wasn't a problem if the user had a deckwith that capability when to original recording was made, but such amachine wouldn't always be available. The reviewer also noted that aswitch to attenuate the analog outputs from +4dBu down to 0dBu, -3dBuor -6dBu would have been helpful for different monitoring situations.The D-10 retailed for less than $3,000.


Do you remember

In May 1994,the Electronic Industries Alliance (EIA) and the National Radio SystemsCommittee (NRSC) were recruiting listeners for subjective testing ofproposed DAB formats at the Communications Research Centre in Ottawa,Ontario. Tests were conducted in sessions of two or three consecutivedays beginning in June 1994 and continuing throughout the year.

Volunteers who were capable of, or accustomed to, judging thequality of audio signals evaluated recordings of audio material thathad been passed through DAB systems under varied impairmentconditions.
