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.

10. Power Input
The MVXA Series requires a 15-20 Volt AC or DC
power supply. A 15VAC tabletop supply is included
with the unit. The provided power supply may only
be connected to a 110/120VAC power receptacle.
11. 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/headphone disconnect jumper may be
moved to the off position to bypass the internal
speaker and headphone jack. See Internal Speaker
Examples on the Front Panel View.
12. Speaker Out Terminals
An external speaker may be connected 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 View). 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.
13. 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.
14. 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.
