The Pioneer -Deck CT-W851R with Super Auto BLE is a part of the best devices of this double cassette tape deck Era. Since the CT-W851R is a dual-tape deck with two drives with 2-tone heads and auto reverse installed, of course you can not expect a backband check during recording. But that's just too much to get over with the other features. Among other things, separate Dolby© modules are also installed, which means that one could theoretically also copy from Dolby © C to Dolby© B. The Super Auto BLE (Bias/Level/EQ) calibration system developed by Pioneer works perfectly and always reliably. The recording computer here, as with all Super Auto BLE devices, is equipped with an 8-bit DA converter. The band measurement is adjusted at 400 Hz, 3,000 Hz and 15,000 Hz respectively. The system works very reliably and rolls back and forth several times during the calibration process as if by magic, in order to then process the three calibration parameters (bias / level / EQ) one after the other. The individual tape calibration is thus a real gain when recording cassettes. Incidentally, Pioneer 's Super BLE calibration was considered probably the best of its kind in the 1990s. Recordings are possible with this well-equipped device with both decks / drives and most functions can also be controlled via the supplied CU-T015 remote control. Thus, in principle, only a few wishes remain open with this tape deck. Perhaps a discreet illumination of the cassette bay would still have made sense, because the tape material still available during a recording can only be checked with empirical values or via the counter.
