Rear Panel
Speaker Jacks
(SPEAKERS)
The speaker outputs are stan-
dard 1/4" phone jacks wired in
parallel. Speaker cables (recom-
mend at least #18 gauge wire)
should be connected between
the MX-101 and the speaker
systems prior to applying pow-
er to the unit.
System Output Jack
(SYSTEM OUT)
The System Out jack is pro-
vided for connection to external
equalizers and / or power amps.
Nominal output level is +4dB
with an impedance of 600
ohms.
Caution
- The MX-101 should
never be operated into less than
a 4 ohms speaker load.
Foldback Output Jack
(FB OUT)
This jack is for connection to
external power amplifiers and /
or equalizers for the on-stage
monitoring system. Nominal
output level is +4dB with an
impedance of 600 ohm.
Caution:
To insure maximum cooling of
the MX-101, adequate clearance
should be maintained between
the rear panel and any other
surface ( 4 - 6 inches should do).
The vents on the bottom and
top of the MX-101 are also
provided for convection cool-
ing. These vents should be kept
clear and open. Failure to do so
may cause thermal shut-down
of the unit.
Power Switch
(POWER)
The power switch is a three-
position type with the middle
position being the "off" posi-
tion. The MX-101 should be
operated in the switch position
which produces the lowest
amount of system hum.
AC Power Cord
The power cord is the three-
wire type with proper ground-
ing facilities.
Earth Terminal (GND)
AC Fuse
Caution
- The ground pin
should not be removed under
any circumstances. If the MX-
101 must be used without prop-
er grounding facilities, a suit-
able grounding adapter should
be utilized.
Operation of the MX-101 with
proper grounding techniques
will result in less system noise
and greatly reduced shock
hazard.
Warning
To avoid possible equipment
damage and / or personnel in-
jury, the fuse should always be
replaced with same type and
rating. Using improper fuses
will also void the warranty. The
MX-101 should always be dis-
connected from AC outlet prior
to changing fuses. If fuses repe-
atedly fails, the unit should be
referred to qualified service per-
sonnel for repair.
