Extension mode The internal resistance of the SS 22 in exchange line mode is about 440 ohms Add this to the loop resistance and check with the maximum rated resistance of the PABX to see if it will work 2 Exchange line mode It is recommended that the SS 22 only be used with low loop resistances in this mode DOC NO SS 22 14 REV 02 Page 6 of 8 SS 22 USER MANUAL When I connect the SS 22 to the amplifier get a loud hum What is causing it It could be a simple matter of a ground loop if the input to the amplifier is un balanced a Always try to keep the cable between the SS 22 as short as possible Make sure the SS 22 is plugged into the same power source as the PA system Try to use a LINE or AUX input if possible If you need to use a balanced MIC input then place a 20dB attenuator in the MIC jack This can be made up of a series 10k resistors in the two live conductors and a 1k resistor between it on the PA System side The Input cable to the PA system may be picking up feedback from the speaker output and causing an ultra sonic whistle This can appear as a hum from the speakers and can even damage the speakers or the amplifier The solutions are as above The above two problems can occur even when using a balanced input amplifier The solutions are the same as above except that the resistors in d above need to be duplicated for both audio legs of the input DOC NO SS
