Important Safety Instructions

Always follow these basic safety precautions when using the MPE-200:

1) Read all the instructions before using the MPE-200. Keep these instructions.

2) Do not block or obstruct the ventilation holes in the side, or the fan opening at the

rear. Locate it away from heat sources such as heat registers, or other products that
produce heat.

3) If the MPE-200 is mounted in a rack case for portable use, rear support brackets

must be provided.

4) The MPE-200 in combination with an amplifier and speakers or headphones might

be capable of producing sound levels that could cause permanent hearing loss. Do
not operate for a long period of time at a high sound level or at a level that is
uncomfortable.

5) The MPE-200 has no user-serviceable parts other than the rear panel fuses. In event

of any of the following, please contact an authorized Summit service station:

• The MPE-200 does not appear to be operating normally or exhibits a marked

change in performance;

• It has been dropped, or the enclosure damaged;

• Liquid has been spilled into it or if it has been exposed to rain.

WARNING:

TO REDUCE THE RISK OF FIRE OR ELECTRIC
SHOCK, DO NOT EXPOSE THIS APPLIANCE TO

RAIN OR MOISTURE.

ATTENTION:

POUR EVITER TOUS RISQUES D'INCENDIE OU DE
DECHARGE ELECTRIQUE, NE PAS EXPOSER A LA
PLUIE OU A L'HUMIDITE.

Grounding Instructions

Improper grounding can cause a risk of electric shock. Check
with a qualified service person or electrician if you doubt the
product is properly grounded.

The MPE-200 must be grounded. In the event of a malfunction,
grounding provides a path of least resistance for electric current to reduce
the risk of electric shock. This product is equipped with a cord having a
grounding conductor and a grounding plug. The plug must be plugged
into an electric supply outlet that is properly installed and grounded in
accordance with all local rules and electrical standards. Protect the power
cord from being walked on or pinched particularly at plugs, convenience
recepticals, and the point where they exit from the apparatus.

1. UNPACKING AND CONNECTING

1.1 Carefully unpack the unit and report any shipping damage

promptly to your Summit dealer and to the carrier.

1.2 The MPE-200 is normally shipped set up for 115 volt AC

(100-125 volts is OK).

For 200-230 and 230-250 volt AC operation, the rear
panel voltage selector should be set to 240v. The fuses

1.5 AUDIO CONNECTIONS

Mic and Eq inputs and outputs are all balanced and floating,
using standard 3-pin connectors on the rear panel. Outputs
are transformer coupled.

To interface unbalanced equipment, connect signal to pin 2,
and tie pin 3 to pin 1. The inputs will also work if connected
'pin 3 hot', but the phase will be inverted.

The Mic inputs can accept up to +21 dBu (+18 dBu if
unbalanced) when set to zero gain, and can be used with
most line level signals. The Mic Pre outputs are always
active. When Eq In is selected, you can insert external
equipment between the Mic Pre outputs and the EQ inputs.
See section 3.3 for details.

INPUT / OUTPUT SPECIFICATIONS

Mic In:
Impedance: 10k ohms
Maximum input level +21 dBu
(at 0 gain)

Line In:
Impedance: 10k ohms
Maximum input level +21 dBu
(at 0 gain)

Outputs:
Maximum level +24 dBu
(internal jumper installed) +28 dBu

All outputs are balanced and transformer isolated

2. SYSTEM OVERVIEW

2.1 The MPE-200 provides two independent channels

which can be controlled separately, or as a stereo pair.
See section 5.4 for details on selecting the channel
mode.

2.2 The Signal flow of one channel is shown below. Note

that the gain trim is in front of the EQ modules, and that
the output meter tap is before the fader. These facts are
important for proper operation of the MPE-200.

SYSTEM OVERVIEW (ctd)

2.2 The MPE-200 has six control modules which are labeled on
the front panel. The outer two modules control Input
functions (mic gain, HP/LP filters, and setup) on the left, and
Master functions (gain trim, presets, setup and fader) on the
right. The four remaining modules control each of the four
equalizer bands, which are post mic preamp. The EQ may be
used separately from the mic preamps which have their own
outputs.

2.3 The MPE-200 uses two types of controls: Displays Switches
and Encoders. In general, pressing the display switch changes
the screen to a new mode. Turning the encoder changes the
parameter, and pressing the encoder knob selects the
parameter associated with that encoder. The display screen
backlight color is used to convey status for each module, but
this information is also contained in the screen contents, to
accommodate users whose color perception is impaired.
