(R) Audio Check and
confirmation
-
1. Link to standard BASE which is connected to Line Simulator.
2. Set line voltage to 48V and line current to 40mA.
3. Input -45dBm/1KHz to MIC and measure Line output level.
4. Confirm that the level is reference sample ? 1.5dBm and confirm that the distortion
level is < 5%.
5. Input -20dBm/1KHz to Line I/F and measure Receiving level at REV1 and REV2.
6. Confirm that the level is reference sample ±1.5dBm and confirm that the distortion
level is < 5%.
