MP™ 400
Powered Mixer
Thank you for purchasing the Peavey MP™ 400! The MP™ 400 is a four-channel, powered mixer packed into an amazing compact package. Featuring only the essential requirements for a sound reinforcement mixer, the MP 400 is a breeze to operate and a joy to own. Quality semiconductor components lend a hand to achieve the excellent audio characteristics and reliable service
that has made the MP Series Mixer so well known.
The MP 400 boasts four discrete channels, each with high and low impedance inputs, a Contour high frequency EQ control, and Reverb and Level controls. The master section offers a three-band equalizer, Master Level and Reverb controls, 1/4" Main and Reverb/Aux Outputs, Aux Input, and Remote Switch Input.
The following guide explains the MP 400 features and the proper operation of each. Refer to the diagrams in each section to locate each feature by its designated number. Throughout this guide, related features will sometimes refer you to another feature using this number system. Let’s begin by listing the main features of the MP 400.
FEATURES:
•Four total input channels
•Reverb control on each channel
•Contour high frequency equalizer on each channel
•1/4" and XLR inputs on each input channel
•1/4" Main Output
•1/4" Aux/Reverb Output
•1/4" Aux Input
•1/4" Remote Switch for reverb defeat
•Master Three-band Equalizer
•Master Level and Reverb controls
•80 W power amp

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.

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 panel diagram next page)
Place this switch in the “ON” position to turn the unit on.
3.POWER LED (See front panel 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 impedance channel input optimized for a microphone or other low impedance source. Pin 2 is the positive input. This connector has +15V phantom power supply on Pins 2 and 3 at all times (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 CHECK 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 simultaneously.
7.LEVEL
Sets the level of the individual channel in the mix.
8.REVERB
Sets the level of the internal reverb for the channel and must be used in conjunction with the master reverb level. It is post gain and will be affected by the LEVEL (7) adjustment. The Reverb/Aux control also determines 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 remove noise or to add brilliance to the signal, depending on the quality of the source.

MASTER FEATURES
10.MASTER LEVEL CONTROL
Controls the overall volume level of the system.
11.MASTER REVERB CONTROL
Controls the amount of reverb that will be heard in the main mix.
12.MASTER EQUALIZATION
Provides ±15 dB equalization at each center frequency. EQ boost is obtained by moving a particular EQ band’s control above the “0” position. EQ cut is obtained by moving 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 room equalization, feedback control and system tone control. No amount 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 segments of the audio passband, which would limit the system’s dynamic range.
13.MAIN OUTPUT
1/4" unbalanced output that can be used as a source for an external amplifier/speaker system feed to other mixers or a tape deck.
14.REVERB/AUX OUTPUT
Plugging into this mono (TS) 1/4" output allows you to utilize external effects devices. In order to return the signal from the external effects unit, use the Aux Input (15). Simply turn the Reverb Master down to defeat the Internal Reverb if desired.
15.AUX INPUT
Use this mono 1/4"(TS) input to insert a line-level signal into the main mix. This signal can originate from a variety of sources including instrument/mic preamps, external effects (see #14), and even an additional sub mixer. This input bypasses the reverb and can be controlled by the Master EQ and Level.
16.REVERB FOOTSWITCH
Provided for connection of the optional remote footswitch (5100). The footswitch is used to activate/defeat the reverb.
