XONE:92 Filter value diode addition
ECN No:
993
Assembly No(s):
003-138 & 003-143 iss.1 & 003-141 iss.1
Date:
March 3
rd
2004
Reason:
To prevent the filters becoming unstable when all channels
are assigned to the crossfader, with filters to crossfader
selected, crossfader response on max and resonance on
max.
Details of change:
On filter 1 and 2 (AG5300 issue 1) resistor R55 needs to change from 27K to 39K
On the slave card (AG5303) a diode (AE3914) needs to be soldered from pin 12
to ground on both connectors CN10 and CN12
This change was applied to issue 1 PCBs from serial no. 060507 until the
introduction of the issue 2 Filter PCBs.
