Tape Machine Distorting on Input!!Help

    Good Morning,

    I need some help calibrating my APR-5002. I've run through the calibration process several times and when I try to record directly from a CD
    source(+4dbu) the play back is distorted. The recorded material is about 12 dbs below full scale and peaks at -6dbs.

    Here are the tape machine parameters:

    Tape = GP9
    MRL Tape(NAB)= 355 nWb/m
    Speed= 15/IPS
    Overbias=3db
    Meter calibration= 0vu(+4dbu)
    Repro/Sync calibration= -6vu
    Recording calibration = 0vu

    I've followed the manual completely to no avail. Please help! I hadn't realize how long its been since I had to deal with a tape machine.

    Ozzie

    Hi Brad,

    Here are the new parameters and still distorting:

    Tape = GP9
    MRL Tape(NAB)= 355 nWb/m
    Speed= 15/IPS
    Overbias=2db
    Meter calibration= 0vu(+4dbu)
    Repro/Sync calibration= +3vu
    Recording calibration = +3vu

    I may have to look for a tech here in Chicago there maybe something else wrong.

    Let me know what you think.

    Ozzie
