Does anyone know if the trigger level can be adjusted downward by opening the case of this little box? My Parasound AV2500u is putting out too anemic of a voltage to activate the trigger except now and then. It works fine on a Parasound Scamp but I used the Niles on the second trigger. Worked fine for a few years. There is voltage on the incoming line, just not enough. Thanks for any info.

I don't know if you can adjust the Niles unit's sensitivity, but I suspect it would be difficult if it is possible at all (others around here may have some thoughts) and potentially warranty-voiding. Have you tried swapping the two trigger outputs from the 2500u (putting the Scamp on trigger 2 and the Niles on trigger 1)?

Thanks for the reply. Yes I tried switching 1-2 but no luck there. The SCAMP triggers on either but it only needs 5-12V, so both trigger lines are working, just not strongly enough anymore to trip the Niles. I don't know whether the input sensitivity of the Niles or the output level of the Parasound has faded. :-(
