Ian.Reeves Posted November 8, 2013 Share Posted November 8, 2013 Hello I am looking at a Spirit Powerstation 600 which currently has a fault, audio going out of the desk via the NL4's works on both however the level of audio coming from the left hand side is that of a 1/4 of the right hand side. I have narrowed down the fault to the amplifier that is built in, I have tested the additional outputs via another amp and both outputs are identical. Is there anyway of being able to narrow down the fault and hopefully repair. I appreciate any response on this topic. Many Thanks Ian Reeves Link to comment Share on other sites More sharing options...
J Pearce Posted November 8, 2013 Share Posted November 8, 2013 I seem to remember these use a insert jack style switching contact socket to enable hacking the signal in or out between main outs and the amplifier ins. I suspect that the switching contacts in the this socket are dirty. Have you tried hard patching main out to amp in with a jack lead? Link to comment Share on other sites More sharing options...
Ian.Reeves Posted November 8, 2013 Author Share Posted November 8, 2013 Hello Jon I have bypassed the built in amp and get a clear even signal on both the left and right jack output to an external amp, I suffer a problem when using the NL4 connections. Is this a related issue? Many Thanks Ian Link to comment Share on other sites More sharing options...

timtheenchanteruk Posted November 8, 2013 Share Posted November 8, 2013 have you tried what jon suggested?? patch out to in, and see what happens, if it goes away, its the insert jack switch contact that's dirty, its essentially doing what your doing, but back to the the internal amp.

Ian.Reeves Posted November 8, 2013 Author Share Posted November 8, 2013 Sorry, I miss read the previous comment. Ill try that now and will come back to you soon. Thanks for the support so far. Many Thanks Ian Link to comment Share on other sites More sharing options...
J Pearce Posted November 8, 2013 Share Posted November 8, 2013 Incidentally I spent two days of my Y10 work experience making Powerstations at the Potters Bar factory. It was enough to persuade me never to do assembly line work, and get the grades needed to enable that vision. The line out is after the main insert, but there is a main out and amp in with switching contacts, that allow you, for instance, to feed the auxes to the onboard amp while sending LR to a bigger system.

Ian.Reeves Posted November 8, 2013 Author Share Posted November 8, 2013 Thanks Jon for that info I have tested as mentioned and the left hand side is still performing at a lower volume..... any other ideas, I'm leaving the office now so will be able to test on monday.

J Pearce Posted November 8, 2013 Share Posted November 8, 2013 That would seem to indicate a power amp fault then, which is harder and more expensive to fix than a dirty contact... Link to comment Share on other sites More sharing options...
