Notes:

1. Measured with an audio input level of -3.0dB.

2. With respect to a single modulated (scrambling) channel.

3. Measured with a short circuit input, at any analogue output, in a 30.0kHz bandwidth.

4. With Input Amplifier gain at 0dB.

5. Measured psophometrically weighted, at any analogue output.

6. Measured in a 30kHz bandwidth.
