Specifications
Specifications apply for measurements from analog left/right input to stereo composite output.
Frequency Response (Bypass Mode):
Follows standard 50µs or 75µs pre-emphasis curve ±0.10 dB, 2.0Hz–15kHz.
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.
The unit can interface with 600
Ω
devices and is therefore compliant with 600
Ω
input requirements.
