MVXA Series Back Panel View (Rear Panel Cover Removed)
Lacing Rail
The MVXA's bottom panel includes
many wire management features.
Holes are located along the back
of the panel for tie wrapping.
These holes are spaced 2" apart
to allow the use of readily available
hardware handles or lacing bars.
There is also a 3/4" opening along
the entire length of the bottom
panel for wire access. The rear
panel cover is also equipped with
knockouts on either end for wire
management.
Line Level Out
Terminals
The MVXA includes a line level
output. The output of the line level
device is not affected by the volume
control.
Speaker Out
Terminals
An external speaker may be con-
nected to the speaker out terminals
for local or remote monitoring. The
external speaker may be operated
with or without the internal speaker
(see internal speaker examples on
the Front Panel Tour). The output
level is adjusted by the front
volume
control. The external speaker level
output is rated at 3 watts into
8 ohms
with a minimum 4 ohm load.
Shields
and Grounding
The MVXA requires a solid "earth ground" connection. The
unit itself is internally grounded from the circuit board to the
chassis and should receive a good "earth ground" under most
mounting conditions. If the unit is not rack mounted or the
powder-coat paint is interfering with the case grounding, then
one of the "S" ground screw terminals should be taken directly
to earth ground.
Grounding is by nature complex and often requires a variety of options.
If the direct connection to earth ground is not desired. Contact technical
support on how to properly break the shield to earth ground connection.
Power Input
The MVXA Series requires a
15-20 Volt AC or DC power
supply. A 15 VAC table top supply
is included with the unit. The
provided power supply may only
be connected to a 110-120 VAC
power receptacle.
Speaker / Headphone
Disconnect Jumper
When an external speaker or line level
device is connected, the internal speaker
and headphone jack continue to operate.
If this is not desired, the speaker/head-
phone disconnect jumper may be moved to
the offposition to bypass the
internal speaker
and headphone jack. See Internal Speaker
Examples on the
Front Panel View.
