TonyMitchell Posted August 25, 2006 Share Posted August 25, 2006 We have a Macrotech MA602 (acquired second hand with other Macrotechs) and the ENABLE and SIGNAL/IOC indicators do not illuminate.The ODEP indicators do illuminate. Any ideas, guys? Tony Link to comment Share on other sites More sharing options...
mikewheeler Posted August 28, 2006 Share Posted August 28, 2006 Hi, A quick shoofty on the Macrotech manual details the indicators as follows: Enable - basically the power on indicator (indicates status of low voltage supply) - if this isn't lit and the amp is passing signal, methinks you have a dud LED.The IOC indicators should glow green when signal present. Try running signal in at full power with no speaker connected - it should flash. If not, methinks you either have more blown LED's or a faulty low voltage power supply. The ODEP indicator should be on at all times, until the amp is running out of steam when it will dim. Do a few tests, and if it appears to be duff might be an idea to get it back to Crown's distributor to get it looked at. Cheers, Mike Link to comment Share on other sites More sharing options...
