Audio Input port colorsource av40

The Audio Input port on the Colorsource AV40 is rated at -10 DbV 316 MV RMS and 29k ohms.. Is it OK to plug in an aux cord from the headphone port on a TASCAM cd player rated at 20mW and 32 ohms? By my conversions, the resulting input would be -2 DbV, which is 8 DbV above recommended..  Worried about damaging the Colorsource.. TY, Rob
