A IEC MAINS SOCKET Standard IEC mains socket accepts supplied power
cord.
B FUSE HOLDERS Replace with 1A SLO-BLO fuse only.
C OUTPUT (XLR) Transformer Balanced:
Pin 1 - Ground (Switchable)
Pin2 - Positive going phase (+)
Pin3 - negative going phase (-).
Connect directly to console mic preamp or outboard mic preamp. This is a
low-Z mic level send and not line level. Phantom power should be disabled on
this channel but the 48 volts will not harm the DI but can cause big noises.
D OUTPUT (1/4" phone jack) Tube buffered unbalanced output to your guitar
amplifier. The gain is within a dB of unity. The advantage to this output is that
it removes the loading effect of the amp and cable from the guitar and
preserves the instrument's high frequencies. EQ switch is active here.
