SPECIFICATIONS
Specifications apply for measurements from analog left/right input to stereo composite output and to FM analog
left/right output. Measurements apply to FM mode of operation.
Frequency Response (Bypass Mode): Follows standard 50µs or 75µs pre-emphasis curve ±0.10 dB, 2.0 Hz–
15 kHz. Analog left/right output and digital output can be user configured for flat or pre-emphasised output.
Noise: Output noise floor will depend upon on the processor settings but is governed by the dynamic range of
the A/D Converter. The dynamic range of the digital signal processing is 144 dB.
Processing Sample Rate: 48KHz - 768kHz depending on processing stage.
Processing Resolution: Internal processing has 24 bit (fixed point) or higher resolution.
Analog Audio Input
Configuration: Stereo.
Impedance: >10k, load impedance, electronically balanced.
Nominal Input Level: Software adjustable -6dBu to +18dBu (24dB range clip ceiling, adjustable in 1dB
steps).
Maximum Input Level: +24 dBu
Connectors: XLR female Pin 1 chassis ground, Pins 2 (+) and 3 electronically balanced, floating and sym-
metrical.
A/D Conversion: 48KHz 24 bit 128x oversampled delta sigma converter with linear-phase anti-aliasing filter.
Filtering: RFI filtered.
Analog Audio Output
Configuration: Stereo, flat or pre-emphasised (50µs or 75µs), FM delayed or not delayed, AES2 or monitor
output, software-selectable.
Source Impedance: 10 Ohm, electronically balanced and floating.
Load Impedance: 600 Ohm or greater, balanced or unbalanced.
Output Level (100% peak modulation): Software adjustable from –12 dBu to +24 dBu peak, into 600 Ohms
or greater load.
Signal-to-Noise: >= 90 dB unweighted (Bypass mode, de-emphasised, 20 Hz–15 kHz bandwidth, refer-
enced to 100% modulation).
L / R Crosstalk: <= –70 dB, 20 Hz–15 kHz.
Distortion: <= 0.01% THD (Bypass preset, de-emphasised) 20 Hz–15 kHz bandwidth.
Connectors: XLR male. Pin 1 chassis ground, Pins 2 (+) and electronically balanced, floating and symmetri-
cal.
D/A Conversion: 48KHz 24 bit 128x oversampled.
Filtering: RFI filtered.
Digital Audio Input
Configuration: AES/EBU Stereo, 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.
Connector: XLR female. Pin 1 chassis ground, pins 2 and 3 transformer balanced and floating, 110 ohm
impedance.
Filtering: RFI filtered.
Digital Audio Outputs (AES1 and AES2)
Configuration: Stereo per AES/EBU standard. Output configured in software as flat or pre-emphasised
(50µs or 75µs), FM delayed or not delayed, AES2 (DR path) or monitor output, software selectable.
Sample Rate: Internal free running at 32, 44.1 or 48 KHz selected in software. Can also be synced to the
AES/EBU digital input at 32, 44.1, 48, 88.1 or 96 kHz, as configured in software.
Connector: XLR-type. Pin 1 chassis ground, pins 2 and 3 transformer balanced and floating, 110 ohm
impedance.
Output Level (100% peak modulation): –20.0 to 0.0 dBfs software controlled.
