SERVICE BULLETIN
Date : March 6, 2000 : AP812/AP818 GROUND HUM UPDATE Re Dear Staff & Dealers,

Due to some feedback from our customers a service issue regarding hum problems have been discovered with the AP812 and AP818 mixer/s. Please be advised that units in production after March 2000 will NOT have this problem. The HUM problem only occurs when the main in/out jacks are used (i.e. if a processor is used). There is considerable hum at the MONITOR OUT jack as well. To solve these problems follow the directions listed below... Required Modification: -------------------------------1. Seperate Top & Bottom 2. Find where the Orange & Green Wires are soldered to eyelets, pretty well in the center of the board (marked with an Orange & Green X on the layout provided). CUT the Orange & Green Wires as close to the EYELETS as possible (on the filter capacitor side). (as shown circled in RED 3. Solder both wires (that you've just cut) to TAB 3 (as shown circled in GREEN) 4. Don't forget to re-connect the Green Wire (female spade) to the Top Mixer (male spade lug)

We are sorry for any inconvenience caused as a result of this problem. For further technical information or assistance please contact Peter Mourtos at Yorkville Sound via phone at (905) 837-8550 Ext. 218 or via email at [email protected] .

Enclosed - the Layout for the AP812/818 M1104 Power Amplifier board with instructions.
