Stereo
Cassette Tape Deck
A
full-feature front loading cassette deck with phase-locked loop (PLL) servo DC
motor drive system and unique "Accu-Bias" control for complete tape
compatibility. Equipped with a newly developed hyperbolic S&S sendust
rec/pb head, Dolby NR with MPX filter, memory rewind full auto stop mechanism,
timer start/pause function, rec-mute switch and large VU meter with two peak
level indicators.
Accu-Bias is
Onkyo's exclusive system. It works with a pair of reference signal generators
built into the TA-630D. Feed these signals to your tape, and read the
reproduction signal on the meters. If bias is off for that cassette tape, you
compensate with continuous variable settings until you get an absolutely flat
frequency response. It's that simple, and you get the best high frequency
response, least distortion and lowest signal to noise ratio.
High Quality
Long Life "S&S" Sandust Head
Onkyo's
recently developed "S&S" Sedust head (made from a highy robust
silicon/iron/aluminum alloy of outstanding magnetic properties) plays a very
big role in achieving the high quality of sound reproduction in the TA-630D.
Extended frequency response 920 Hz - 18,000 Hz with chrome tapes) and an
exceptionally wide dynamic range make your recordings sound professional-like.
