Bit Split - Steinberg NUENDO 8 I/O 96k Handbuch

Bit Split

Especially digital tape recorders are often limited to 16 bit resolution. To use the com-
plete dynamic range of the Nuendo 8 I/O 96k with such devices the functions BIT
SPLIT and COMBINE were integrated. This technique is a simple but effective solution,
differently used by several manufacturers.
The method used in the Nuendo 8 I/O 96k is compatible to the one used by Yamaha in
their digital mixing desk 02R, so the Nuendo 8 I/O 96k can be used directly in 24 bit
operation with this desk. Additional the COPY MODE (see chapter 8.2 Copy Mode) al-
lows an operation of BIT SPLIT and COMBINE in digital domain. This allows to use the
ADAT inputs of the 02R with full 24 bit resolution (normally limited to 20 bit).
BIT SPLIT divides the 24 bit signal into a 16 bit and an 8 bit signal. When recording on
16 bit machines two tracks are required for each channel, an 8 track machine will
record 4 channels. To transmit all 8 channels of the Nuendo 8 I/O 96k two digital inter-
faces (16 tracks) are provided and have to be used.
On the rear of the Nuendo 8 I/O 96k two ports of each TDIF and ADAT format named
MAIN and AUX can be found.
When PROCESS BS is active, the analog inputs are processed to the digital outputs as
shown below:

Output
As long as not more than the first 4 channels are used only the MAIN output is neces-
sary. It makes no sense to connect AUX as it carries no data. When using inputs 5-8 the
AUX output also has to be used and carries the data of inputs 5-8.
