AUX IN (Auxiliary Input)
The AUX IN is an additional audio input to the ISD5100-Series, such as from the microphone circuit in
a mobile phone “car kit.” This input has a nominal 694 mV p-p level at its minimum gain setting (0 dB).
See the following table. Additional gain is available in 3 dB steps (controlled by the I
9 dB.
1. Gain from AUX IN to ANA OUT
2. Gain from AUX IN to ARRAY IN
3. 0TLP Input is the reference Transmission Level Point that is used for testing. This level is typically 3 dB below
