Orban 5750 Technical Manual
Specifications
Load Impedance: 600Ω or greater, balanced or unbalanced. Termination not required or recommended.
Output Level (100% peak modulation): Adjustable from –6 dBu to +24 dBu peak, into 600Ω or greater load,
software-adjustable.
Signal-to-Noise: >= 90 dB unweighted (Bypass mode, de-emphasized, 20 Hz–15 kHz bandwidth, referenced to
100% modulation).
L/R Crosstalk: <= –70 dB, 20 Hz–15 kHz.
Distortion: <= 0.01% THD (Bypass mode, de-emphasized) 20 Hz–15 kHz bandwidth.
Connectors: Two XLR-type, male, EMI-suppressed. Pin 1 chassis ground, Pins 2 (+) & 3 (-)
electronically balanced, floating and symmetrical.
D/A Conversion: 24 bit 128x oversampled, with high-pass filter at 0.15 Hz (–3 dB).
Filtering: RFI filtered.
Digital Audio Input
Configuration: Stereo per AES3 standard, 24 bit resolution, software selection of stereo, mono from left, mono
from right or mono from sum.
Sampling Rate: 32, 44.1, 48, 88.2, or 96 kHz, automatically selected. Can be used as a sync reference.
Connector: XLR-type, female, EMI-suppressed. Pin 1 chassis ground, pins 2 (+) and 3 (-) trans- former balanced and
floating, 110Ω impedance.
Input Reference Level: Variable within the range of –30 dBFS to –7 dBFS (VU)./ -23 dBFS to 0.0 dBFS
Filtering: RFI filtered.
Digital Audio Outputs
Configuration: Two outputs, each stereo per the AES3 standard. The outputs can be independently set to emit the
analog FM processed signal, the digital radio processed signal, the low-delay monitor signal or a 384/192 kHz
digital composite baseband output.
The FM processed signal can be configured in software as flat or pre-emphasized to the chosen processing pre-
emphasis (50μs or 75μs). The digital radio processing chain receives the output of the multiband limiter and
processes it through a look-ahead peak limiter that operates in parallel with the main FM peak limiting system. The
DR and FM signals are always simultaneously available.
