SPECIFICATIONS
ORBAN MODEL 1101
Output Level:
+4dBu nominal; Clip level +18dBu unbalanced, +24dBu balanced.
Software adjustable via OPTIMOD-PC Mixer Application and Windows Mixer API.
Signal-to-Noise:
90dB unweighted signal-to-noise, 20Hz-20kHz
(bypass mode).
Distortion:
<0.01% THD (bypass mode), 20Hz-20kHz.
DA Conversion:
24-bit 128X oversampled D/A with linear phase anti-imaging filter.
DC Offset:
Less than 10mV differential offset.
Highpass Filter:
-3dB 2.0Hz.
Audio Connector:
DB-25, EMI suppressed.
Digital Audio Input
Number of Inputs:
2, each with Sample-Rate Converter. The two inputs can accept asyn-
chronous inputs and will allow them to be mixed. One of the inputs can also be config-
ured as sync reference to lock output sample rate to the sample rate at this input.
Configuration:
Stereo AES/EBU (AES3-1992/AES18) or S/PDIF, 24-bits resolution, soft-
ware selection of stereo, mono from left, mono from right, or mono from sum (as source
to use as a mono processor).
User Bits:
AES18 compliant. Incoming User Bits will pass through to Digital Output. User
Bits can also be inserted or extracted via Serial or Ethernet using OPTIMOD-PC Control
Application.
Impedance:
Transformer balanced and floating, 110 ohm impedance, AES/EBU.
Sample Rate:
20-96kHz.
Input Level:
Variable within the range of -20 to 0dBFS (Peak) in 0.5dB steps.
Software adjustable via OPTIMOD-PC Mixer Application and Windows Mixer API.
Internal Input:
See Wave Audio Input above.
Audio Connector:
DB-25, EMI suppressed.
Word Clock Connector:
DB-25, EMI Suppressed and/or BNC.
User Bits:
User bits present at Digital Input 1 are passed automatically to Digital Output 1.
This behavior is automatic and cannot be defeated.
Digital Audio Output
Number of Outputs:
2
Configuration:
Two-channel per AES/EBU-standard (AES3-1992) or S/PDIF (consumer)
standard, software selectable.
Output Level Control:
Peak level is adjustable from -20 to 0dBFS in 0.1dB steps; software-
adjustable via OPTIMOD-PC Mixer Application and Windows Mixer API.
Sample Rate:
Internal free running at 32kHz, 44.1kHz, 48kHz, 88.1 kHz, or 96 kHz, se-
lected in software. Can also be synced to either AES/EBU input at 32kHz, 44.1 kHz, 48
kHz, 88.1 kHz, or 96 kHz, all ±4%.

To prevent out-of-band noise from causing falsely high noise readings, noise and distortion specifica-
tions must be verified by a bandpass filter having a very sharp cutoff at 20 kHz. We use an 801-line FFT
analyzer and integrate the noise power in the bins from 0 to 20 kHz.
