Note: All measurements made using "Bypass" mode, which is available in the Input/Output Submenu.

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".
