        I am a happy owner of H9 for many years, and, recently, purchased H90.
        H90 is positioned only in the loop of Marshall jcm 2000 dsl
        and is set in the global as “line”, both in and out, in serial.
        In A/B comparison between h9 and h90, the second, set as above, has a very very low signal level.
        H9, compared to H90, seems to ‘come to life’.It has a higher and more present sound
        In your experience what could I have done wrong on H90?

        Thank you very much for your help!

          Hello ming,

          The H9 operated at instrument level, though it could take signals up to line level. Have you tried operating the H90 at instrument level instead? Taking a look at the JCM 2000 manual, I see there is a “LOOP LEVEL” knob that can be used to match an effects processor in the loop. If you prefer to run the H90 at line level, you may need to adjust this knob to match the right operating level. My advice would be to use one of H90’s INIT Programs which can be found on the User 2 playlist. It simply consists of to THRU utility algorithms. The idea is the level when the H90 is bypassed should match the level when the H90 is active. Adjust this loop level knob accordingly.

            Hello Joe,
            thanks for your reply. I will try this!
            Sorry… even if I remain doubtful: how is it possible that my H9 max, without ever having made any level I/O setting/adjustment (instrument/line/levels) works – by itself – at an optimal signal level in the effects loop of the Jcm 2000, and with H90 I have these problems??

              The H9 was designed to work mainly with instrument levels. It’s possible the amp loop level knob was set low from the beginning and you didn’t notice it. It may be the case if you set the H90 to instrument level instead of line level, you won’t have any volume disparity. Regardless, between the loop level and operating levels of the H90, you have everything you need to adjust things perfectly.
