TECHNICAL DATA Orban Model 6200
Digital Audio Output
Configuration: Two-channel AES/EBU-standard. (AES3-1992).
Output Level Control: Peak level is adjustable from 0 to −20dBFS in 0.1dB steps. Con-
trolled by software. (See System Settings).
Sample rate: Internal free running at 32 kHz ±10 PPM, 44.1 kHz ±100 PPM, or 48 kHz ±10
PPM, selected in software. Can also be synced to the AES/EBU SYNC input or the
AES/EBU DIGITAL input at 32 kHz ± 4%, 44.1 kHz ± 4%, or 48 kHz ± 4%.
Word Length: Selectable 20, 18, or 16 bit. Optional dither can be added, with level ad-
justed appropriate to word length. This is first-order noise-shaped dither (that is, white
TPDF dither of peak amplitude equal to the quantizer step size with noise shaping spec-
tral density of 6dB/octave). It sounds substantially quieter than white triangular PDF
dither but, in contrast to more extreme noise-shaped dither, it adds only 3dB un-
weighted noise by comparison to white PDF dither.
Sync: Internal free running or external per AES11. The “AES/EBU SYNC Input” is the pri-
mary source for external sync. The “AES/EBU Input” is an alternate source.
Connector: XLR-type, male, EMI-suppressed. Pin 1 chassis ground, Pins 2 and 3 trans-
former balanced and floating.
Status/User Bits: The channel status optionally supports the SPDIF or AES/EBU formats.
The user bits received from the “AES/EBU Input” are optionally passed through to the
output. The 192-bit block structure is used where preamble “Z” indicates the start of
block.
Jitter: Less than 10ns rms.
RF Filtering: Effective 0.5-1000MHz.
Digital Input Sync
Configuration: Used for synchronization of the Digital Output signal to an external refer-
ence provided at this input. Labeled “AES/EBU Sync Input.”
Sampling Rate: 32, 44.1 and 48 kHz.
Connector: XLR-type, female, EMI-suppressed. Pin 1 chassis ground, Pins 2 (+) and 3
transformer balanced and floating, 110 ohm impedance.
Filtering: RFI filtered.
Remote Control Interface
Configuration: Eight (8) inputs, opto-isolated and floating, and two open-collector fault tally
outputs.
Inputs Operate: Controlled by software (see System Settings).
Control: Momentary or continuous contact closure, minimum current required is 10mA;
maximum permitted current is 30mA, which is achieved with a 9V DC input.
Note: More than one contact closure can be active at once. If one contact is held, and
another is closed then the second requested function is activated.
Tally Outputs: Two tally outputs provided on the Remote Interface Connector, indicating
Loss of Digital Signal Lock and Loss of Digital Sync Lock.
These tally outputs are provided as two open collectors. A tally condition is defined to
be active (the collector conducts to supply common) when the fault condition exists.
When the fault condition does not exist, the tally outputs will be high impedance with no
pull-up resistor.
