Nearly imperceptible
quick reverse recording and playback is featured in AIWA's advanced AD-R470
cassette deck, which is certain to impress budget-minded audio enthusiasts
everywhere. Amazingly quick 0,3 second auto reverse during both recording and
playback is assured by AIWA's accurate radial-pivot mechanism, which turns the
tape head 180 degrees in the blink of an eye.
Feather-touch full
logic IC controls respond to a light touch, with Cue & Review for speedy
location of desired pasages.
Sound quality
features include Dolby HX Professional circuitry, which improves high frequency
response regardless of the tape type, and an amorphous tape head for superb
sound linearity. (The C, H, and U versions feature AIWA's super hard DX head
for a corresponding level of performance.) Plus, Dolby B and C noise reduction
reduce tape hiss for clear recordings that capture the dynamic performance of today's digital and high-level
analog sound sources. And, the fine bias control allows +/-20% adjustment to
obtain the best response from Normal and CrO2 tapes.
Dolby HX
Professional
Not a form of noise
reduction, Dolby HX professional is an advanced method for varying bias
according to the characteristics of audio signals for an audible improvement in
high frequency response. HX stands for "headroom extension'" and it
operates during recording to dynamically adjust bias levels in response to the
unput signals. This contributes to significant improvements in dynamic range, while at the same time making possible
"flatter" response in the upper frequencies. Under ordinary
conditions, normal-position tapes recorded with Dolby HX professional actually
outperform CrO2 tapes recorded without it in terms of high frequency response.
You'll be amazed at the sound clarity and absence of distortion. Better yet,
since Dolby HX professional is applied during recording only, the benefits can
be heard when playing back these tapes on any playback equipment.
