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 letterC

C appears on the EQUALIZER

display indicating a compare function is being performed.

While the MEMORY button is held, what is heard is the

Stored Memory curve—releasing the MEMORY button

allows you to hear the edited Working Memory version.

USING STORED CURVES. To use any of the curves in

Stored Memory, all you do is show the Stored Memory

location on the red SYSTEM display. Whatever number

shows is the label of the Stored Memory location for the

current Working Memory.

Working Memory is the scratch pad where you work. You

can think of it as the129th memory location (like the 19th

hole in golf), except you cannot actually store anything

here—only operate on it, or listen to it. When a Stored

Memory location shows up on the SYSTEM display, the

curve is actually in two locations: safely stored at the memory

location shown and in the Working Memory scratch pad,

ready for you to change if you want. You can do anything

you want to the Working Memory without altering the

original stored version. When complete, you must store this

new version either in place of the old curve, or into a new

location. This is the significance of the MEMORY light

blinking. Once you do anything to the original curve, the

MEMORY light starts blinking to remind you it changed.

If you want a different curve, press the UP/DOWN

buttons to scroll, or directly enter a number via buttons 0

through 9 (observe the red SYSTEM display). Please note

that all Stored Memory numbers must be at least two digits;

e.g., Stored Memory number4 is entered as 04, etc. For direct

access to Stored Memory locations above 99, push the 100

button, then the next two digits. For example, to recall stored

memory125, press 100, 2 and 5. Once the last digit is

entered, the program is instantly called up (what you see is

what you hear). What could be simpler?

BYPASS MODE. Pressing either BYPASS 1 or 2 causes

all audio in the selected Channel to be routed around the

equalizer electronics. Please note that a bypassed condition

cannot be stored. If recalling a flat curve is required, simply

store a program in which all filter and level controls are set to

zero (Factory Preset1, if it has not been overwritten in Stored

Memory).

MIDI CHANNEL. Pressing the CHANNEL button

displays the currently assigned MIDI Channel. Pressing UP/

DOWN increases or decreases the MIDI Channel number.

You may select from1 through16, orOFF.

MIDI CONTROL. The MPE 14 can be controlled by

another MPE, an RPS 4 Remote Program Switch (contact

closure to MIDI Program Change converter), personal

computer, or any device capable of transmitting MIDI. A

DOS program is available from the factory by request. Details

are, you guessed it, in the MPE Users Guide.

OTHER FEATURES. To say the MPE 14 does a lot

more than explained in this brief space is like saying a

personal computer makes a good paperweight. Please read the

MPE Users Guide for a more in-depth look at your MPE 14.

POWER SUPPLY. As noted elsewhere in this manual,

NEVER USE A POWER SUPPLY WITH YOUR MPE 14

OTHER THAN THE ONE SUPPLIED FROM THE FACTORY

OR AN EXACT REPLACEMENT FROM RANE CORPORA-

TION.The MPE 14’s power supply input is designed for an

AC supply, delivering 18-24 volts, from a center-tapped

transformer capable of supplying at least the current de-

manded by this product. Using any other type of supply may

damage the equalizer and void the warranty (which at two

years parts and labor is worth safeguarding, don’t you think?).

Additional information and full technical specifications

will be found on the enclosed MPE 14 Data Sheet.

FCC & VDE NOTICE

This equipment has been tested and found to comply

with the limits for a Class A digital device, pursuant to

Part 15 of the FCC Rules, and similar requirements found

in European specifications VDE 0871/0875. These limits

are designed to provide reasonable protection against

harmful interference when the equipment is operated in a

commercial environment. This equipment generates, uses,

and can radiate radio frequency energy and, if not

installed and used in accordance with the instruction

manual, may cause harmful interference to radio commu-

nications. Operation of this equipment in a residential area

is likely to cause harmful interference in which case the

user will be required to correct the interference at their

own expense. USE OF SHIELDED MIDI CABLES IS

REQUIRED FOR FCC COMPLIANCE.

CHASSIS GROUNDING

The unit is shipped with its Ground Lift switch in the

CHASSIS GND position. This ties signal ground to

chassis ground. If after hooking up your system it exhibits

excessive hum or buzzing, there is an incompatibility in

the grounding configuration between units. Here are some

things to try:

1. Try combinations of lifting grounds on units

supplied with Ground Lift switches (or links).

2. Verify all chassis are tied to a good earth ground.

3. Units with outboard power supplies do not ground

the chassis through the line cord. Make sure these units

are solidly grounded by tying the Chassis Ground Point to

known earth ground (such as a power amplifier chassis).

Use a star washer to guarantee proper contact.

SOFTWARE UPDATES

Please fill out and mail in the enclosed registration card.

Notification of any software revisions will be mailed to all

registered users. Failure to register could result in missing

important update information.
