SETUP
Setup
The Setup menu holds all general Setup-parameters
including parameters normally found in Utility, Level and
I/O menus.
Basic Operation
Press the SETUP key to enter the Setup page.
Use the ARROW keys to select parameter.
Use the CONTROL wheel to change parameter value.
All changes are instantly carried out.
Mono/ Stereo In
The channel select on Analog Inputs is done automatically
via sensing on the Input connectors.
Input Select
Dial the CONTROL wheel to select between Analog or
Digital.
Analog Input
When "Analog" is selected the DTWO automatically
defaults to the internal 44.1kHz clock as Sample Rate.
Digital Input
When "Digital" is selected the DTWO attempts to lock to
the S/PDIF Input. During the lock-up period the "DI" display
icon blinks indicating none or unacceptable clock, and the
Outputs are muted.
When lock is achieved the "DI" icon turns solid, and the
Outputs are un-muted.
Clock
Analog Input
When Input source is analog the following Sample Rates
are available:
Internal 44.1kHz - The DTWO runs at internal 44.1kHz.
Internal 48kHz - The DTWO runs at internal 48kHz.
Digital - The DTWO locks to the incoming Digital clock.
Digital Input
When Input Source is digital the following Sample Rates
are available:
Internal 44.1kHz - The DTWO runs at internal 44.1kHz.
Internal 48kHz - The DTWO runs at internal 48kHz.
Digital - The DTWO locks to the incoming Digital clock.
Please note that when using internal clock with
external digital audio, the incoming digital audio
must be in sync with the DTWO internal clock in
order to avoid slip-samples.
***Rate Mismatch****
This Error message will occur in the display if the
DTWO detects slip-samples. Typically this problem
only occurs in very special clock setups e.g. if the DTWO
is running via internal clock, while processing audio from
the Digital Input. If the incoming clock and the internal
clock does not match the DTWO will display the above
written error message.
Out Range
Sets the maximum Gain range of the analog Output stage.
Range: 2dBu, 8dBu, 14dBu and 20dBu.
Analog Out Level
Adjusts the Analog Output level.
Digital In Gain
Adjusts the Digital In level. This parameter is only active
when Digital In is selected.
Dither
Going from one type of bit resolution to a lower, e.g. from
24 bit to 16 bit, you actually loose 8 bits of information.
The process of cutting off bits is called truncation and it
introduces digital distortion of low level signals, due to the
lack of complete signal information. To compensate for this,
dither must be applied. Dither is a small amount of filtered
noise that generates randomization at the noise floor,
ensuring a less distorted low level signal.
Dithering is relevant only on digital Outputs and it is always
the receiving device that determines the number of bits you
must dither to. A CDR or a DAT recorder should normally
be dithered to 16 bit.
Status Bits
Sets whether the DTWO is sending out AES/EBU(profes-
sional standard or S/PDIF(consumer standard) status bits.
Delay Unit
Select ms (milliseconds) or BPM (Beats Per Minute).
