General Audio Specifications
Frequency Response:
± 0.50 dB, 20 Hz to 20 kHz with high pass filter disabled.
Distortion:
Less than 0.05% THD 20 Hz – 20 kHz bandwidth.
*Signal-Noise Ratio:
Greater than -100 dB, 20 Hz –- 20 kHz bandwidth, referenced to 0dBfs
*The measured noise floor will depend upon the settings of the Input and Output Gain controls and is primarily governed
by dynamic range of the Crystal Semiconductor A/D Converter which is specified as >100 dB. The dynamic range of the
internal digital signal processing chain is >144 dB.
Stereo Separation:
Greater than 80 dB, 20 Hz –- 20 kHz; 90 dB typical.
Analog Audio Input:
Left/Right Stereo.
Electronically balanced.
Input impedance 10k ohms resistive.
Maximum Input Level +24 dBu.
Nominal Input Level: +4dBu (A +12dBu input results in –12dBFS input meter
reading with Input Gain set to 0.0dB. A 0dBu input signal results in a -12dBFS input
level when Input Gain is +12dB.)
A/D Conversion:
Crystal Semiconductor 24 bit 128x oversampled delta sigma converter with linear-phase
anti-aliasing filter. Pre-ADC anti-alias filter, with high-pass filter at <10 Hz.
Connectors:
Two, EMI-suppressed XLR-female. Pin 1 chassis ground, Pin 2 "Hot".
Analog Audio Output:
Left/Right Stereo. Electronically balanced.
Output Impedance 20 ohms.
Minimum load Impedance 600 ohms.
Output Level adjustable from -2 dBu to +22dBu peak in 0.1dB steps.
D/A Conversion:
Crystal Semiconductor CS4390 24 bit, 128x oversampled.
Connectors:
Two, EMI-suppressed XLR-male. Pin 1 chassis ground, Pin 2 “Hot".
Digital Audio Input:
Configuration: Two-channel stereo per AES3 standard via CS8420 Digital
Audio Transceiver with 24-bit resolution. Software selection of stereo, mono from left,
mono from right or mono from sum. Automatically accepts sample rates between 24 kHz
and 96 kHz.
Connector:
EMI-suppressed RJ-45 female pinned according to StudioHub+
 standards. Transformer
isolated, balanced, and floating according to AES3 standard.
Digital Audio Output: Stereo per AES3 standard. Digital Output sample rate software selectable for internal
48kHz, synchronize to AES input, or synchronize to auxiliary AES sync input (per AES-
11 / DARS).
Connector:
EMI-suppressed RJ-45 female according to StudioHub+
 standards.
Transformer isolated, balanced, and floating according to AES3 standard.
Digital Output Level: -22.0 to 0.0 dBFS peak, software adjustable in 0.1dB steps.
