MISSION 777 OPERATING INSTRUCTIONS
(Bracketed numbers refer to panel drawings)
FRONT PANEL
1. GREEN L.E.D. (1) This light illuminates when the amplifier is turned on.
2. ON/OFF SWITCH (1) Self explanatory.
BACK PANEL
1. A.C. CONNECTOR HOUSING (2) & (3)
The detachable line cord connects to the 777 at A.C. input (2). Access to the line fuse (3) is possible only
when the line cord has been disconnected & the clear plastic window is moved aside. The fuse housing (3)
also contains a small universal voltage card that selects the correct line voltage for the country in which the
amplifier is used. See precautionary measures for correct line voltage & fuse rating.
2. INPUT (6)
Interconnect cables from the pre-amplifier output connect here.
3. OUTPUT (5)
These five way heavy duty binding posts provide different methods of connecting the speaker cable to
the amplifier. For example, when using multi-strand heavy gauge wire, divide the conductors into two
parts, pass one half through the hole in the terminal & wrap the remainder around the terminal post.
Tighten plastic cap to secure wire. These terminals are also equipped to accept standard banana plugs.
4. OUTPUT FUSE (4)
Individual 3.5 ampere fast blow fuses are installed at the factory. These fuses protect the loudspeakers
from overload conditions & the amplifier from shorted speaker wires. See precautionary measures for
correct fuse rating.
5. SOFT CLIP (7) IMPORTANT NOTICE
Due to inherently excellent clipping characteristics & ample headroom of the 777 power amplifier,
reports from the field & recommendations made by many reviewers indicate that the soft clip feature
incorporated in the amplifier is redundant.
In order to simplify & at the same time eliminate any degradation of the sonic quality which may arise
from intentional or inadvertent usage of this feature, the soft clip switch has been completely disabled.
