Front Panel, Patch Bay & Buss Link
Power Amplifier Input Jack
(PWR AMP)
The PWR Amp input jack allows
the internal power amplifier to
be used with external equip-
ment. When a plug is inserted,
the power amp is automatically
disconnected from the MX-106
mixer section. The nominal
input level is +4dB with an
input impedance of 10k ohms.
Program Output Jack
(PGM OUT)
The PGM Out jack is provided
for connection to external equal-
izers and/or power amps, deriv-
ing its signal prior to the internal
GEQ and power amp. Nominal
output level is +4dB with an
impedance of 600 ohms.
Effects Output Jack (EFF OUT)
The EFF Out jack used in
conjunction with the EFF/RET
Jack allows use of an external
effects device in place of the
internal analog echo unit. The
effects out jack should be con-
nected to the input of the
external effect unit. Nominal
output level is —10dB with an
impedance of 600 ohms.
Effects Return Jack (EFF /RET)
The EFF/Ret jack is provided to
connect an external effects de-
vice to the MX-106. When a plug
is inserted the internal echo unit
is automatically switched out of
the MX-106 circuitry, being
replaced by the external unit.
This jack should be connected to
the output of the external effects
unit. Nominal input level is
—20dB with an impedance of 50k
ohms.
Graphic Equalizer Input Jack
(GEQ)
The GEQ input jack allows the
graphic equalizer to be used
independently of the MX-106
with other external equipment,
or the internal power amplifier
and the graphic equalizer with
external equipment. When a
plug is inserted, the main mix
from the program buss is dis-
connected from the graphic
equalizer and the power ampli-
fier. The nominal input level is
+4dB with an input impedance
of 50k ohms.
Graphic Equalizer Output Jack
(GEQ OUT)
This jack allows the MX-106
and the internal graphic equal-
izer to be used with an external
power amplifier, or in conjunc-
tion with the GEQ in jack, to be
used independently of all other
MX-106 circuitry. Nominal out-
put level is +4dB with an
impedance of 600 ohms
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 ohms. If the
internal power amp and equal-
izer are to be used for the on-
stage monitor system, the FB
output should be connected to
the GEQ input jack.
AUX 1, AUX 2 Input Jack
(AUX 1, AUX 2)
-20dB 10k
Program Buss Link Jack
(PGM) +4dB 22k
Fold Back Buss Link (FB)
+4dB 22k
Echo/Effects Buss Link Jack
(EFF) +4dB 22k
Buss Link Jacks
The buss link provides direct
access to the PGM, FB, and
effects mixing busses, and is
provided for easy input ex-
pansion with additional MX-
106 units or other auxiliary
equipment. All jacks have an
input level of +4dB with an
impedance of 22k ohms.
Recording Output Jack
(REC OUT)
The Rec Out jack obtains its
signal prior to the program
master output, and is intended
for connection to external re-
cording equipment. Nominal
output level is —10dB with an
impedance of 1k ohms.
Rear Panel
Power Switch (POWER)
The power switch is a three-
position type with the middle
position being the "off position.
The MX-106 should be operated
in the switch position which
produces the lowest amount of
system hum.
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-106 and the speaker
systems prior to applying power
to the unit.
Caution
- The MX-106 should
never be operated into less than
a 2 ohm speaker load.
AC Power Cord
The power cord is the three-wire
type with proper grounding
facilities.
Caution
- The ground pin should
not be removed under any
circumstances. If the MX-106
must be used without proper
grounding facilities, a suitable
grounding adapter should be
utilized. Operation of the Mx-
106 with proper grounding tech-
niques will result in less system
noise and greatly reduced shock
hazard.
AC Fuse
The proper fuse rating for 110-
120V AC operation of the MX-
106 is 7 amps.
Warning
- To avoid possible
equipment damage and/or per-
sonnel injury, the fuse should
always be replaced with same
type and rating. Using improper
fuses will also void the war-
Cord Wrap
The cord wrap is provided for
convenient storage of the power
cord when the MX-106 is not in
use.
Caution
- The power cord should
always be completely removed
from the cord wrap prior to
operation of the unit. This will
insure maximum cooling of the
MX-106. For the same reason,
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-
106 are also provided for con-
vection cooling. These vents
should be kept clear and open.
Failure to do so may cause
thermal shut-down of the unit.
ranty. The MX-106 should al-
ways be disconnected from AC
outlet prior to changing fuses. If
fuse repeatedly fails, the unit
should be referred to qualified
service personnel for repair.
