Precautions
MX400 User’s Guide
Precautions
1. Location
Keep the unit away from locations where it is likely to be exposed to high tem-
peraturesorhumidity—suchasnearradiators,stoves,etc.Alsoavoidlocations
which are subject to excessive dust accumulation or vibration which could
cause mechanical damage and locations subject to strong electromagnetic
fields,such as close to broadcast equipment.
2. Ventilation
The unit has ventilation slots on the bottom panel. Do not block these vents.
3. Avoid Physical Shocks
Strong physical shocks to the unit can cause damage.Handle it with care.
4. Do Not Open the Case or Attempt Repairs or Modifications Yourself
Thisproductcontainsnouser-serviceableparts.Referallmaintenancetoqual-
ifiedYamaha service personnel.Opening the case and/or tampering with the
internal circuitry voids the warranty.
5. Always power off before making connections
Always turnthepowerOFFbeforeconnecting ordisconnectingcables.This is
importanttopreventdamagetotheunititselfaswellasotherconnectedequip-
ment.
6. Handle Cables Carefully
Alwaysplugandunplugcables—includingtheACpowercord—bygripping
the connector, not the cord.
7. Clean With a Soft Dry Cloth

Introduction
Thank you for purchasing theYamaha MX400.The MX400 series is designed
foreasyoperation andversatility inawiderange of applications,includingPA
and installed systems.The MX400 series includes three models; 8 channel,12
channel,16 channel,and 24 channel mixers.
In order to take full advantage of the MX400’s functionality, please read this
manual carefully.
Features of the MX400
Each of the mono input channels provides the following functions.
• XLR/phone input jacks
• 20dB pad switch / continuously variable gain control
• 3bandEQ(withvariablemid-rangefrequency)/EQon/offswitch/high
pass filter switch
• TRS insert jack / direct output
• Atotalof 5AUXSENDsystems (pre

• ODD/EVEN group and stereo assign switch / pan control
• Channel ON switch
• PFL switch
• Level meter for accurate level control
Inadditiontothemonoinputchannels,4setsofstereoinputchannelsarepro-
vided, with the following functions.
• Four stereo inputs with 2 band EQ
• GROUP/AUX/STEREO assign switches
• Balance/pan control
• TRS 1/4”phone jack and RCA input jack select switch (only for stereo
input 1/2)
The master section provides the following features.
• Five fader-style AUX SEND controls
• Independent 3 point level meter for each AUX SEND control
• TO ST switch and pan control for each GROUP
• GROUP ON switch,AFL switch,and 100 mm fader for each GROUP
• The MONI/ST2 switch allows the ST2/MONI OUT output signal to be
switched in the following two ways;
1) Oneofthesignalsfromanexternalsourceinputtothestereobus,the
PFL bus,or the 2TR IN.
2) The same signal as the ST1 OUT output signal.
• ONswitch,L+Rswitch,andfaderareprovidedfortheST2/MONIOUT
output signal.
In addition,the following functions are provided.
• XLR mic inputs
• Talkback level control
• Assign switch
The TAPE IN jacks and REC OUT jacks have level controls,for convenience
when you need additional margin for monitoring or recording. The level
meters with peak indicators allow accurate monitoring.

20dB pad switch
This is a 20dB input pad (attenuator) that affects INPUT A and INPUT B.
If thelevelof the inputsignal istoohighfor adjustmentstobe madeusing

GAIN control
This controls the gain of the preamp for INPUT A and INPUT B. Gain is
variable to a maximum of 44dB.
TheGAINcontrolisalwaysusedinconjunctionwiththeSIGNALindicator
andthePEAKindicator.Adjustthe GAIN controlsothattheSIGNALindi-
cator is always lit when an input signal is present,and the PEAK indicator
lights occasionally.If thePEAKindicatorlightsfrequently,lowertheGAIN
control to prevent the signal from distorting.The following table shows
usual settings for the GAIN control.

The signals controlled by AUX 3 andAUX 4 will depend on the setting of
the PRE switch.
• When the PRE switch is not pressed
They control the post-fader signal.
• When the PRE switch is pressed
They control the pre-fader signal.
AUX 5 controls the post-fader signal.

Input Specifications
*1. Sensitivity is the lowest input level that will produce an output of +4dB (1.23V) or the nominal output level when MX400 is set to
maximum gain (i.e. all level controls and faders set to maximum).
*2. XLR-type connectors and phone jacks (TRS) are balanced (Tip=HOT, Ring=COLD, Sleeve=shield).
*3. Insert phone jacks (TRS) are unbalanced (Tip=out, Ring=in, Sleeve=GND).
*4. Phone jacks are unbalanced.
*5. The talkback jack is unbalanced.
*6. In these specifications, when dB represents a specific voltage, 0dB is referenced to 775mV RMS,and when dBV represents a specific
voltage, 0dBV is referenced to 1V RMS.
