Reg Report post #1 Posted January 12, 2017 Have just come across an old Soundcraft LM1 mixer that I'd like to dust down and get working properly again. If anyone is familiar with this mixer i'd like to know how to adjust the 1khz tone generator level so it hits 4ppm/0dbu when the master L-R is up to 0. At the moment tone is lining up between 4.5-6PPM when I'm adjusting the needle sensitivity with a tweaker (doesn't go any lower). Thanks in advance! Share this post Link to post Share on other sites

Reg Report post #3 Posted January 19, 2017 Hi Philip yes I've got a copy of this manual, and have taken the front panel off to try adjusting tone level sensitivity, and L&R sensitivity, but to no avail. The tone level changes even when pressing the illumination button on/off?! I'm guessing there's a problem in the internal power circuit somewhere. Thanks for the link though!

Philip Perkins Report post #4 Posted January 19, 2017 Besides asking Soundcraft support, you might consider buying an hour of a bench-tech's time to look at this, and get advice on if it is fixable (and the general health of the board). Share this post Link to post Share on other sites
Reg Report post #5 Posted January 19, 2017 Am awaiting a response from Soundcraft (Harman), hopefully soon! Good shout about a bench tech Share this post Link to post Share on other sites
ivanovich Report post #6 Posted February 10, 2017 at least the channel strips are modular. i've had to resuscitate a channel on a Ghost which is not modular, what a PITA!!! Share this post Link to post Share on other sites
