Can I use analog bargraphs for digital inputs (or digital scales for analog inputs)?
Yes. The range colors, break points and level references are set for the scale type and NOT the
source assigned.
For example assuming the following settings:
- Analog scale type: AES/EBU
- Analog/Digital scale reference: -18dBfs
- Analog 0dB reference: 0dBu
- Digital upper range point: -18dBfs
- Digital lower range point: -40dBfs
Feeding in analog 0dBu will produce a level of -18dBfs, with the color changes occurring at
-40dBfs and -18dBfs.
Changing the Analog 0dB reference to +4dBu will produce a level of -22dBfs, with the color
changes unaltered.
Changing the Analog/Digital reference to -20dBfs (with the anlg ref still at +4dBu) will produce a
level of -24dBfs, with color changes unaltered.
The same applies to displaying digital channels on an analog scale; the color changes will adhere
to the analog upper and lower settings.
Can bargraphs be assigned to any source and placed in any position on the
screen?
Yes, providing Channels are assigned to Bars manually. Refer to the Matrix Setup section of
the SYSTEM menu in the Operation chapter.
What are the digital and analog bar groups for?
These groups reflect the two different types of external signal type; digital or analog.
Rules exist to automatically create these groups according to the type of installed external input
card to allow channels in the external input and output buses to be monitored effectively.
The scales used depend on user preferences made in the Scales menu and need not match
signal type.
The rules used are explained in detail in the Analog and digital groups section of the LEVEL
BARS menu in the Operation chapter.
How can I force channels and bars to 1:1 correspondence so that bars are ordered
from left to right to reflect the default channel numbering?
This is done automatically if the 1:1 option is selected for MADI OUT 1, 2 and EXTERNAL OUT
MATRIX in the Matrix Setup section of the SYSTEM menu in the Operation chapter.
Can digital audio be balanced or unbalanced?
Yes. AES/EBU inputs may be jumper selected per channel to be either balanced or unbalanced
inputs. The settings are set via jumpers on each digital audio input card as explained in the
installation section.
What are the RS232 options?
DTS/RTS select and half/full duplex via jumpers on the rear serial port pcb as explained in the
installation section. Access to this board requires removal of the top cover with power removed.
