4.6 Audio Level Input Sensitivity

• Adjust RV210 (line sensitivity) fully clockwise.

• Check that the input sensitivities are better than those specified below:

Note: A degraded signal to noise ratio can be expected with the compressor

selected. The extent of the degradation is dependent on the audio input

level.

Line Input 600 ohms, ±3kHz (±2.4kHz) [±1.5kHz] deviation at

1kHz:

with compressor -50dBm

without compressor -30dBm

Microphone Input 600 ohms, ±3kHz (±2.4kHz) [±1.5kHz] deviation at

1kHz:

with compressor -75dBm

without compressor -55dBm

CTCSS Input 1kHz deviation at 150Hz 500mV rms
