Interface Toughbook Mic Input to Line Out from SWL's PSK20
I want to interface the audio from the Small Wonder Labs PSK20 to the
mic input in the Toughbook CF27 laptop. The computer has no line input, and I plan to use the mic input via the port replicator. The Toughbook reference manual doesn't give any specs for the mic input. The user manual does contain this caution: "Use only a monaural condenser microphone (miniature jack). Using an input source other than a monaural condenser microphone may not allow audio to be input or may damage the equipment." Reading suggests that an L pad in the 40-60 dB range is required, but I would like to narrow this down before experimenting. Any experiences using the Toughbook on PSK would be helpful. Thanks, Tom, N3IJ |
