Art DIGITAL MPA II [10/24] Digital section front panel controls

When the switch is in the “Dual” position the output controls act on only their respective channels.

+4/-10 switch (rear panel)

The +4/-10 switch is used to set the output level of the DIGITAL MPA II for the appropriate system

levels. This feature allows you to match 0 VU on the meters of the DIGITAL MPA II and your mixer or

other equipment.

When depressed, 0 VU on the output meter corresponds to +4dBu on the outputs. In –10 mode, the

output level measures –10dBV.

Meter Trim

The Meter Trim is used to adjust the Meter’s “0” point when. This may change if the unit is NOT

mounted with the front panel perpendicular to the floor.

Using a small flat-blade screwdriver you can mechanically fine-tune the meter indicator position if, for

example, it does not rest at the leftmost position when the unit is OFF.

Adjustments for feedback readings, when the unit is in use, are internal and are not user serviceable.

Digital Level control

The levels driving the A/D converter are adjusted with this control. The topology of the DIGITAL MPA

II lends itself to simultaneous use of the analog and digital outputs, as each has its’ own level control.

Common to both is the output signal of the tube circuit.

The Digital Level control is variable from +10dB to -∞ (fully muted).

Located before the Digital Level control is the insert jack, allowing processing to be added before

digital conversion.
