Analog Inputs - Steinberg NUENDO 8 I/O 96k Mode D'emploi

Analog Inputs

The Nuendo 8 I/O 96k's rear provides 8 (stereo) 1/4" TRS jacks and a 25 pin D-sub jack.
Both are internally connected, so not operational at the same time. The electronic in-
put stage is built in a servo balanced design which handles monaural and stereo jacks
correctly. When used unbalanced it automatically corrects the gain by 6 dB.
❐
When using unbalanced cables with XLR jacks pin 3 of the cables jack should be con-
nected to pin 1 (ground). Otherwise noise may occur, caused by the unconnected nega-
tive input of the ADI's balanced input.
The 25-pin D-sub connector follows the pinout known from devices manufactured by
Tascam. Refer to chapter 10 for a pinout listing. We do not recommend to make such a
cable by yourself, as it is extremely difficult to integrate 8 balanced lines into a small D-
sub housing without shorts. Your dealer will be glad to provide you with a profes-
sional Tascam multicore, D-sub to XLR, made in the length of your choice.
One of the main issues when working with an A/D-converter is to maintain the full dy-
namic range within the best operating level. Because of this Steinberg's Nuendo 8 I/O
96k includes electronic switches of the newest technology, which introduce no addi-
tional noise or distortion to the audio path. The key INPUT LEVEL allows a perfect ad-
aptation for all 8 channels to the most often used levels -10 dBV and +4 dBu.
Each analog input has a 'Signal Ok' and 'Over' LED, so levels and Overload of each
channel are easy to check. The green LED begins to light at -40 dBFS in an analog fash-
ion (more bright at higher levels). When this LED lights up only seldom or never, the
input level is too low, causing a noisy and distorted recording.
The 'standardized' studio levels do not result in an (often desired) full scale level, but
take some additional digital headroom into consideration. The amount of headroom
is different in different standards and again differently implemented by different man-
ufacturers. Because of this we decided to define the levels of the Nuendo 8 I/O 96k in
a most compatible way. The headroom of the Nuendo 8 I/O 96k is defined according
to the chosen reference level.
