Analog to Digital
Physical access to the analogue inputs is either via 1/4” stereo jack socket or 25-pin D-type connector conforming to the Tascam DAxx analogue I/O pinout. These recorders are very common, so a
suitable multicore cable (e.g. for connecting directly to mixing consoles or to XLR) should be relatively easy to  nd. The entire input stage - from the sockets to the converter chip’s internal input - is
fully symmetrical. This is a special servo-balanced input circuit: if the signal at the input is unbalanced, input gain is automatically adjusted by +6 dB. Otherwise input sensitivity for an unbalanced
signal would have been lower than for a balanced one.
Any A/D converter is only as good as the gain compensation at the input. The ADI-8 has 3 gain levels, making it compatible with a wide range of studio equipment - loss is avoided before the
signal gets to the A/D converter. Input gain is switchable between Lo Gain, +4 dBu and -10 dBV, and employs a special damping technique: using latest hi-grade electronic switches (ADG 451),
the gain switch could be placed in the best possible position within the signal path. This approach makes additional ampli er circuitry or long cables to mechanical components unnecessary (and
obsolete.) The D/A converters get the best quality signal possible, so they can reach maximum SNR (signal-to-noise ratio) with minimum distortion.
