ZomBiE Posted May 22, 2004 Report Share Posted May 22, 2004 a simple attenuator uses just 2 resistors, so that impedance would stay in acceptable level u should know both output and input impedances of both devices. then it's quite easy to calculate values and make attenuator from pot and 1 fixed resistor, or just 2 fixed resistors.

audioguru Posted May 22, 2004 Report Share Posted May 22, 2004 This attenuator reduces the speaker or earphone level from the scanner to the microphone level of the recorder. Use shielded cable. Quote Link to comment Share on other sites More sharing options...
