POWER
This section describes the proper application of AC power to your MP 400. To insure the safety
of you and your MP 400, please pay close attention to any designated cautions.
REAR PANEL
1. IEC POWER SOCKET:
With the Power Switch #2) in the off O) position, plug the power cord into this connector
prior to plugging it into your AC power source. Always insure that proper grounding practices
are utilized. Damage to the equipment may occur if improper line voltage is used see voltage
marking on unit). Never remove or cut the ground pin of the line cord plug.
NOTE: FOR UK ONLY
As the colors of the wires in the mains lead of this apparatus may not correspond with the
colored markings identifying the terminals in your plug, proceed as follows: 1) The wire which
is colored green and yellow must be connected to the terminal which is marked by the letter
E, or by the earth symbol, or colored green or green and yellow. 2) The wire which is colored
blue must be connected to the terminal which is marked with the letter N, or the color black.
3) The wire which is colored brown must be connected to the terminal which is marked with
the letter L or color red.
2. POWER SWITCH (See front pane diagram next page)
Place this switch in the “ON” position to turn the unit on.
3. POWER LED (See front pane diagram next page)
Illuminates when AC power is being supplied to the mixer.
SPEAKER CONNECTIONS
This section will help you locate the two speaker output jacks on the rear of your MP 400.
WARNING: NEVER ALLOW YOUR TOTAL SPEAKER IMPEDANCE TO DROP BELOW
THE MINIMUM IMPEDANCE OF 4 OHMS.
4. SPEAKER OUTPUTS
Two parallel 1/4" jacks are provided at the output of the power amplifier for ease of speaker
connection. Minimum speaker impedance min. load) is 4 ohms.

CHANNEL FEATURES (CHANNELS 1-4)
The following section describes channels 1-4. Each of these input channels is identical.
5. MIC (LOW Z) INPUT
XLR balanced low i pedance channel input opti ized for a icrophone or other low
i pedance source. Pin 2 is the positive input. This connector has +15V phanto power
supply on Pins 2 and 3 at all ti es (Pin 1 is the ground reference).
WARNING: BECAUSE THE LOW-Z INPUTS HAVE PHANTOM POWER, ONLY CONNECT
MICROPHONES OR PRODUCTS WITH A BALANCED OUTPUT TO PREVENT DAMAGE.
IF YOU ARE UNSURE, PLEASE CHEC THE PRODUCT’S OPERATING INSTRUCTIONS.
6. LINE (HIGH Z) INPUT
1/4" unbalanced input that accepts line level sources equipped with a 1/4" plug (TS). The two
inputs (XLR and 1/4") cannot be used si ultaneously.
7. LEVEL
Sets the level of the individual channel in the ix.
8. REVERB
Sets the level of the internal reverb for the channel and ust be used in conjunction with the
aster reverb level. It is post gain and will be affected by the LEVEL (7) adjust ent. The
Reverb/Aux control also deter ines the level of signal sent to the Effects Output (14).
9. CONTOUR
A shelving type of active tone control that varies the treble frequency level ±15 dB at 10 kHz.
It is designed to re ove noise or to add brilliance to the signal, depending on the quality of
the source.

MASTER FEATURES
10. MASTER LEVEL CONTROL
Controls the overall volu e level of the syste .
11. MASTER REVERB CONTROL
Controls the a ount of reverb that will be heard in the ain ix.
12. MASTER EQUALIZATION
Provides ±15 dB equalization at each center frequency. EQ boost is obtained by oving a
particular EQ band’s control above the “0” position. EQ cut is obtained by oving a particular
EQ band’s control below the “0” position. The following list describes each EQ control and its
center frequency.
Low - shelving type - 80 Hz
Mid - peak type - 1 kHz
High - shelving type - 10 kHz
OPERATION NOTE: This equalizer is designed to provide roo equalization, feedback
control and syste tone control. No a ount of equalization will correct the response curve
of a poor loudspeaker. Always begin with all controls in the “0” position and avoid excessively
cutting large seg ents of the audio passband, which would li it the syste ’s dyna ic range.
13. MAIN OUTPUT
1/4" unbalanced output that can be used as a source for an external a plifier/speaker
syste feed to other ixers or a tape deck.
14. REVERB/AUX OUTPUT
Plugging into this ono (TS) 1/4" output allows you to utilize external effects devices. In order
to return the signal fro the external effects unit, use the Aux Input (15). Si ply turn the
Reverb Master down to defeat the Internal Reverb if desired.
15. AUX INPUT
Use this ono 1/4"(TS) input to insert a line-level signal into the ain ix. This signal can
originate fro a variety of sources including instru ent/ ic prea ps, external effects
(see #14), and even an additional sub ixer. This input bypasses the reverb and can be
controlled by the Master EQ and Level.
16. REVERB FOOTSWITCH
Provided for connection of the optional re ote footswitch (5100). The footswitch is used to
activate/defeat the reverb.
