. The MPE 28 is supplied with a remote power supply suitable for connection to this input

jack. Consult the factory for replacement or substitution.

9. GROUND LIFT Switch.

 This switch gives the user the option to tie signal ground to chassis ground. Typically, a system is

quieter in the LIFT position. See 

CHASSIS GROUNDING

 note on last page for details.

OPERATING INSTRUCTIONS

THE BASICS.

 Don’t be intimidated by the fact that the

MPE 28 is a programmable equalizer with a lot of buttons on
the front and none of the familiar slide controls and rotary
pots and such. The product is very straightforward and
following the steps below should get you started.

EDITING CURVES.

 Changing the overall Level or

equalizer curve requires the use of the EQ Edit mode. To edit
any curve, push the 

EQ

 button (repeated operation cycles

between the lower-half of the available frequencies, the
upper-half, and Off. Now press 

LEVEL

 or any of the 14

frequency buttons (the yellow LED lights to acknowledge
selection). Next scroll the 

UP/DOWN

 buttons until the

desired Level shows on the green 

EQUALIZER

 display.

When finished editing, push the 

STORE

 button once. The

number in the 

SYSTEM

 display starts blinking to remind you

to select a location, or to use the current one. Enter a new
number if needed, then push 

STORE

 again to place the new

curve into the Stored Memory location shown. The 

MPE

Users Guide

 should be consulted for further details.

STORING CURVES.

 Any curve may be stored in any or

all of the 128 memory locations. Once stored, this location is
referred to as the Stored Memory location. To begin the
process, press 

STORE

 once. This causes the 

SYSTEM

display to begin blinking the current Stored Memory location
number. If you want to store your Working Memory curve
into this location, press 

STORE

 again and your wish shall be

granted. If not, select another Stored Memory location using
the number keys or the 

UP/DOWN

 buttons. When the correct

location is displayed, press 

STORE

 again. The curve in the

selected location has now been replaced with the curve of the
current Working Memory.

COMPARING CURVES.

 A most useful feature is the

ability to compare the changes you have just made with what
is in the Stored Memory location. The MPE 28 makes this
easy by using the 

MEMORY

 button when in the EQ Edit

mode. All changes to the Working Memory are compared
with the Stored Memory by pressing and holding the

MEMORY

 button. The letter

C

C

 appears on the 

EQUALIZER
