I have a mixer attached to the mag input on the cp55 to give me PA and extra aux inputs, question is : how do i increase the gain, i know there are a selection of circuit boards in the CP55, which one do i tweak? Thanks Michael  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 04-25-2003 03:51 PM                     if memory serves there is only a header to select input level hi or low but gain adjustment is done in the mag preamp  |  IP: Logged Bernard Tonks Jedi Master Film Handler Posts: 619 From: Cranleigh, Surrey, England Registered: Apr 2001 posted 04-25-2003 06:42 PM                     On my Dolby CP 55 I used to run a 10 channel power mixer through the non-sync card which has gain adjustments. This was for a mic, CD/MD, Revox 1/4 inch open reel. The mixer was also used for 16mm & DVD projection sound. I would suggest a 600 ohm isolating transformer on each leg, available from Radio Spares or Maplins.  |  IP: Logged
