Figure 9: Microphone Connection to the Unit
The audio input to the unit is connected to a LINE IN interface and must meet the following specifications:
Input impedance: 10k Ω
Input capacitance: 30 pF
Maximum input level: 2 Vrms
Minimum detectable input level: 20 mVrms
To connect an audio source to the unit
1.
Connect an audio splitter cable (not supplied) to the AUDIO IN/OUT port located on the front
panel of the unit. See Figure 4: trk100/trk100d Front Panel (page 3) and Figure 6: trk200 Front
Panel (page 5).
2.
Connect the RCA audio input connector on the other end of the audio splitter cable to the
audio device (microphone/amplifier).
