NOTES: 20. All monitor output tests are performed with a 10-kΩ load resistance.
21. Monitor gains are measured with a 1020-Hz, 6-V peak-to-peak sine wave applied differentially between
IN + and IN –.The monitor output gains are nominally 0 dB, – 8 dB, and – 18 dB relative to its input; however,
the output gains are – 6 dB relative to IN + and IN – or AUX IN + and AUX IN –.
22. Squelch is measured differentially with respect to ADC VMID.
