Subject: TDT-system: PA4 clicks From: "George, E.L.J." <elj.george@xxxxxxxx> Date: Mon, 16 Jan 2006 11:55:20 +0100Dear colleagues on this list, we are using Windows XP and a standard RS232-cable to operate a TDT-II system, equiped with a PA4. The PA4, however, produces some soft, clicky sound when the attenuation is changed (using PA4atten), even when no input signal is present. Switching between DC- / AC-operation or Auto / Manual mode has no effect. Rewiring the power connectors does not help either. Does anyone recognize this problem and have any hints to a solution ? Thanks in advance, yours sincerely, - Erwin George ------------------------------------------- drs. Erwin L.J.
