@ SUPER AUTO BLE
(First Double Deck with a 3-point BLE)
In conventional 2 head units, bias, level and equalizer were tuned using the 2-point AUTO BLE (400 Hz and 10 kHz) to flatten the
frequency characteristic. Although most tapes could be flattened by this method, medium band correction (3 kHz) has been added and the
dip of medium band which rarely occurs has been improved this time to flatten the frequency characteristic even more. The 3-point BLE
has already been used in 3 heads units to perform adjustments. However, this is the first time it is used in a 2 heads unit.
