Brief Description and Characteristics

NUENDO 8 I/O

6 Brief Description and Characteristics

The Nuendo 8 I/O is an 8-channel analog to digital and digital to analog converter in a

19" rackmount enclosure of 1 U height. Latest 24 bit converters using 128 times over-

sampling result in more than 110 dB dynamic ratio. This value is not only printed in the

brochure, thanks to our Low Jitter Design it is available with every sold unit.

The servo balanced analog inputs and outputs are fitted with both D-sub (for optional

XLR multicore) and 1/4" TRS jacks. The complete signal path from the jacks to the ADC

is balanced. The digital inputs and outputs are available as ADAT optical and TDIF-1

connectors.

One of the main issues when working with an AD-converter is to maintain the full dy-

namic range within the best operating level. Steinberg’s Nuendo 8 I/O includes elec-

tronic switches of the newest technology, which introduce no additional noise or

distortion to the audio path and operate as remote controlled level attenuators. Two

switches on the front panel control all electronic switches of all channels for a perfect

adaptation 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 are easy to check.

The AD-converter can provide internal clocks (44,1 and 48 kHz) at all digital outputs.

The unique Intelligent Clock Control technology (ICC) enables a flexible operation

with internal clock at 44,1 and 48 kHz, external word clock or the digital input signals.

These options, also available for the DA-conversion, are easy to understand and easy

to use. The current state of locking and clock synchronisation is shown by blinking or

constant lit LEDs.

The digital section of the Nuendo 8 I/O includes two outstanding functions. Bit Split al-

lows to split one 24 bit signal to two 16 bit outputs. This technique allows for example

to use two 8-channel 16 bit tape recorders to record 8 channels in 24 bit resolution.

Using Bit Combine will put the splitted signals back to one full 24 bit signal. The

method of splitting/combining is compatible to the method used by Yamaha in their

digital mixing desk 02R, so the Nuendo 8 I/O can be used directly in 24 bit operation

with this desk!

Furthermore the unique Copy Mode allows to use the device completely in the digital

domain. Copy Mode routes the digital input to the digital outputs ADAT and TDIF. As

these operate simultaneously with identical data the Nuendo 8 I/O not only turns into

a superiour ADAT/TDIF converter but also allows copying between devices of the

same format and a distribution to different devices. In Copy Mode both Bit Split and

Combine are also available, so the functionality is boosted again. That's why we call

our Nuendo 8 I/O an Intelligent Audio Solution.

First Usage - Quick Start

NUENDO 8 I/O

12 First Usage - Quick Start

The clearly structured front panel design ensures an easy start when working with the

device for the first time. Nevertheless we recommend to study at least the chapters

'Clock Section' and 'Copy Mode', as the extensive usage of format converter and clock

options may result in some behaviour that may require further explanation.

Connect the analog inputs with the analog signal source. Change the input sensitivity

by pressing INPUT LEVEL until the input level is sufficient to avoid noisy operation. Try

to achieve an optimum input level by adjusting the source itself. Raise the input level

until the Over LED's flash at the loudest parts of the signal, then reduce the level a bit

until no more overs are detected.

The analog line inputs of the Nuendo 8 I/O can be used with +4 dBu and -10 dBV sig-

nals. They are fitted with both D-sub (for an optional XLR multicore) and 1/4" TRS

jacks. Both are internally connected, so not operational at the same time. The elec-

tronic input 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 switched on the Nuendo 8 I/O starts in a default mode which should be suitable

for most applications:

• AD-converter in master mode (CLOCK INTERNAL)

• DA-converter in slave mode (CLOCK INPUT)

• Sample rate 44,1 kHz

• Input ADAT optical

On the DA-side you just have to choose the desired digital input by pressing DIGITAL

INPUT. A coarse correction of the analog output level can be done by pressing OUT-

PUT LEVEL.

We recommend Steinberg’s ST24/96 or Nuendo 9652 digital interface cards for digital

data transfer into a PCI bus equipped computer. These cards have the highest reputa-

tion and are the ultimate solution for master and multitrack tasks.

Inputs and Outputs

NUENDO 8 I/O

14 Inputs and Outputs

Analog Inputs

The Nuendo 8 I/O'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 input

stage is built in a servo balanced design which handles monaural and stereo jacks cor-

rectly. 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 short circuits. Your dealer should be able to sell you 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 AD-converter is to maintain the full dy-

namic range within the best operating level. Because of this Steinberg’s Nuendo 8 I/O

includes electronic switches of the newest technology, which introduce no additional

noise or distortion to the audio path. The key INPUT LEVEL allows a perfect adaptation

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 in-

put level is too low, causing a noisy and distorted recording.

The 'standardized' studio levels do not result in a (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 in a

most compatible way. The headroom of the Nuendo 8 I/O is defined according to the

chosen reference level.
