    Hi All,

    My name is Andrew and I am new to the Allen and Heath SQ5. We just purchased one for our live tv studio to record at the ministry I work for. My SQ5 is located in the control room that is separate from the actual studio.

    I have a question regarding gain structure. I have hooked up a Shure SLXD wireless mic system to my SQ5. I am using it for a Lav Mic system. I seem to be getting a lot of white noise out of that channel. What is the best gain structure to use here between the pre amp gain and trim and fader so I can eliminate the white noise from my Lav Mic?

    Start off with making sure the mic offset level in body pack is at 0db.
    What output level is the receiver set at?

    No one can really tell you exact numbers to set levels at as a lot depends
    on the how the mic is being used.

    The receiver is at +9 the mic pack is at 0. If I don’t have the receiver at +9 I have to run the pre amp at 48 or so to get adequate volume

    If you PFL that channel what does metering show for level?

    What is the channel trim level set at?

    Do you the PAD turned on on that channel?
    (If the pad is turned on turn down the channel fader and the gain
    before turning the PAD off!!!)

    Are you doing a lot of compression, EQ or other processing
    on that channel.

    Do you have another mic to try on the body pack?

    How does that channel work if you just plug a mic into it.?
