I'm not sure if this will blow anything up but my MF350 amp manual says:
Emulated Output Level -10dBV * see note 1
FX Send Level Switchable -10dBV, +4dBV * see Note 2
Note 1: Recommended for connectionto inputs with input impedance >20kohm
Note 2: Recommended for use with line level equipment (i.e. rack processor etc.)
