damage, in case of malfunction in the power section.
Before replacing a fuse the mains cord must be
disconnected from the mains outlet.

AUX INPUT connector
This aux signal input is electronically balanced and
accepts audio levels between –18dBu to +22dBu on
line level, and –38dBu to +2dBu on mic level. When
mic level is selected, +30 V DC phantom power is
supplied to the XLR-3 aux input connector. Pin
