Introduction
Thank you for purchasing the Yamaha MM1402 mixer. The MM1402 is a mixer that
provides 6 MONO IN channels and 4 STEREO IN channels, for a total of 14 inputs. It is a
console-type stereo mixer suitable for a wide variety of input sources.
Features
●The six MONO IN channels feature two types of input jack; XLR type MIC IN jacks (con-
tinuously variable over –14 ~ –60 dB, balanced) and TRS phone LINE IN jacks
(continuously variable over +10 ~ –36 db, balanced). The MIC IN jacks are also able to
provide +48 V phantom power for condenser mics.
●Each of the four STEREO IN channels features L/MONO and R phone jacks (switchable –
20/–10/+4 dB, unbalanced), two band equalization, and an AUX SEND (PRE) system,
meeting the requirements of a wide variety of sources.
●Two AUX return systems are provided for use as effect unit returns or stereo source inputs.
TAPE IN and REC OUT jacks are also provided for recording/playback on a stereo
recorder.
●All of the 14 inputs provide a PFL (pre fader listen) switch, allowing you to monitor the
signal or input level using headphones or MONITOR OUT.
●A five-band master graphic equalizer is provided in the STEREO OUT stage, allowing
equalization of the overall output for sound field compensation or feedback prevention.

Precautions
1. Location
Keep the unit away from locations where it is likely to be
exposed to high temperatures or humidity — such as near
radiators, stoves, etc. Also avoid locations 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 side and bottom
panels. 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 Modifi-
cations Yourself
This product contains no user-serviceable parts. Refer all
maintenance to qualified Yamaha service personnel.
Opening the case and/or tampering with the internal
circuitry voids the warranty.
5. Always power off before making connections
Always turn the power OFF before connecting or discon-
necting cables. This is important to prevent damage to the
unit itself as well as other connected equipment.
6. Handle Cables Carefully
Always plug and unplug cables — including the AC
power cord — by gripping the connector, not the cord.
7. Clean With a Soft Dry Cloth
Never use solvents such as benzine or thinner to clean the
unit. Wipe clean with a soft, dry cloth.
8. Always Use the Correct Power Supply
Make sure that the power supply voltage specified on the
rear panel matches your local AC mains supply. Also
make sure that the AC mains supply can deliver more than
enough current to handle all equipment used in your
system.

1GAIN control
Use this knob to adjust the level of the input signal to the optimal level.
For the best balance of S/N ratio and dynamic range, adjust this knob so that
the peak indicator 5lights occasionally.
For mic inputs connected to the XLR connector, the range is –14dB ––60dB.
For line inputs connected to the phone connector, the range is +10 ––36dB.
2HIGH, MID, LOW equalizer (3 band)
These knobs control high, mid and low equalization at the following frequen-
cies.HIGH: 12kHz, maximum effect ±15dB
MID: 2.5kHz, maximum effect ±15dB
LOW: 80Hz, maximum effect ±15dB
When the knob is in the center position, the response will be flat.
3AUX 1, 2 controls
These knobs control the level of the signal that is output to the AUX buses.
Since AUX1 is placed before the channel fader, it will be unaffected by the
position of the channel fader. Since AUX2 is placed after the channel fader, it
will be affected by the channel fader level. By outputting a signal only from
AUX SEND 1 or AUX SEND 2 and not from the ST OUT jacks, you can also
use these as supplementary outputs.
4PAN control (panpot)
This knob assigns the signal of each channel to the STEREO L and R buses,
determining the stereo location of the sound.
5PEAK indicator
This indicator detects the level of the signal at a point after the EQ (pre fader).
It will light red at 3dB before clipping to warn that the signal is approaching
clipping level.
6PFL switch (input channel)
This switch allows you to monitor the signal of the input channel at the pre
fader level. You can use headphones or MONI OUT to conveniently check
the input signal of a specific channel, or trouble-shoot a channel that is having
problems.
7Channel fader
This fader controls the output level of the input channel signal, adjusting the
volume balance between channels. Faders of channels not in use should be
pulled down.

These are balanced phone connectors to which line-level
equipment can be connected (T: hot, R: cold, S: GND).
The nominal impedance is 600Ω.
3LINE IN (7L–14R)
These are unbalanced phone jacks to which line level
devices can be connected. They are used as four sets of
stereo inputs (7L, 8R)–(13L, 14R). If only the L jack is
used, the input signal will be mono and the same signal
will be input to the R jack as well.
4AUX SEND (1, 2)
These are unbalanced phone jacks.
The nominal output level and nominal impedance are
+4dB/600Ω.
5AUX RTN (1, 2)
These are unbalanced phone jacks.
The nominal output level and nominal impedance are –
10dB/600Ω. They are used as two sets of stereo inputs
(1L, 1R)–(2L, 2R). If only the L jack is used, the input sig-
nal will be mono and the same signal will be input to the R
jack as well.
6MONI OUT (L, R)
These are unbalanced phone jacks to which the power
amp driving your monitor speakers can be connected.
They output the same signal as the PHONE jack located
on the control panel.
7ST OUT (L, R)
These are unbalanced phone jacks to which the power
amp driving your main speakers can be connected.
Phantom Power Warning
To prevent hazard or damage, connect only
microphones and cables that conform to the

APOWER switch
This switch turns the power on.
BPHANTOM switch
This switch turns the phantom power on/off for all
channels.
Use this when you are using condenser microphones.
When this switch is turned on, DC +48 V will be supplied
to pins 2 and 3 of each input MIC IN 1–6.

Introduction
Nous vous remercions d’avoir porté votre choix sur le mélangeur MM1402 de Yamaha. Le
MM1402 vous propose 6 canaux MONO IN et 4 canaux STEREO IN, un total de 14 bornes
donc. Il s’agit d’un mélangeur stéréo de type console adapté pour une large variété de sources
d’entrée.
Caractéristiques
●Les six canaux MONO IN ont deux types de bornes d’entrée: Bornes MIC IN de type XLR
(variables de façon continue sur –14 ~ –60 dB, symétriques) et des prises casque LINE IN
TRS (variables de façon continue sur +10 ~ –36 dB, symétriques). Les bornes MIC IN peu-
vent également fournir une alimentation fantôme de +48 V pour micros à condensateur.
●Chacun des quatre canaux STEREO IN est doté de prises casque L/MONO et R
(commutables –20/–10/+4 dB, asymétriques), d’une égalisation de deux bandes et d’un
système AUX SEND (PRE) qui permet de répondre aux exigences d’un grand nombre de
sources.
●Deux systèmes de retours AUX sont disponibles; vous pouvez les utiliser comme retours
de processeurs d’effets ou comme entrées pour source stéréo.Les bornes TAPE IN et REC
OUT vous permettent d’enregistrer ou de reproduire sur enregistreur stéréo.
●Les 14 bornes sont pourvues d’un commutateur PFL (pre fader listen/écoute avant curseur)
vous permettant de contrôler le signal ou le niveau d’entrée via le casque ou MONITOR
OUT.
●Un égaliseur master cinq bandes est prévu à l’étage STEREO OUT. Il permet une égalisa-
tion générale du signal de sortie afin d’effectuer des compensations dans le champ sonore
ou pour éviter tout phénomène de rétroaction (feedback).

Précautions
1. Emplacement
Ne placez pas l’appareil dans un endroit où il risque d’être
exposé à des températures élevées ou une forte humidité
(évitez la proximité de radiateurs, poêles, etc). Evitez éga-
lement les endroits poussiéreux ou soumis à des vibrations
qui peuvent être à l’origine de dommages mécaniques
ainsi que les endroits sujets à des champs magnétiques
importants, tels que la proximité de matériel de transmis-
sion.
2. Ventilation
L’appareil est pourvu de fentes d’aération sur les pan-
neaux latéraux et inférieur. Ne bloquez jamais ces fentes.
3. Evitez tout choc
Un choc relativement important peut endommager l’appa-
reil. Maniez-le donc avec soin.
4. N’ouvrez pas le boîtier et n’essayez pas d’effectuer des
réparations vous-même
Cet appareil ne contient pas d’élément pouvant être réparé
par l’utilisateur. Veuillez donc confier toute réparation à
un technicien Yamaha qualifié. Toute tentative d’ouver-
ture du boîtier et de manipulation des circuits internes se
soldera par la perte du bénéfice de la garantie.
5. Coupez toujours l’alimentation avant de procéder à
des branchements
N’oubliez jamais de mettre les appareils hors tension
avant de brancher ou de débrancher des câbles afin de ne
pas endommager l’appareil lui-même ainsi que le matériel
qui y est branché.
6. Manipulez les câbles avec soin
Pour brancher et débrancher des câbles (y compris le câble
d’alimentation), prenez-le toujours par la prise et non par
le câble.
7. Nettoyez avec un chiffon doux et sec
N’utilisez jamais de solvants, tels que du benzène ou un
diluant pour nettoyer l’appareil. Prenez les poussières
avec un chiffon doux et sec.
8. Utilisez toujours une source d’alimentation adéquate
Assurez-vous que la tension spécifiée sur l’arrière de l’ap-
pareil correspond bien à celle de votre secteur et que les
prises utilisées peuvent assurer le courant nécessaire pour
faire fonctionner tout votre système.

1Commande GAIN
Utilisez ce bouton pour régler le niveau du signal d’entrée de manière opti-
male.
Pour obtenir le meilleur équilibre entre le rapport signal/bruit et la plage dyna-
mique, réglez ce bouton de telle sorte que la diode de crête 5s’allume spora-
diquement.
Pour les micros branchés àla borne XLR, la plage est de –14dB ~ –60dB.
Pour les entrées ligne branchées àla borne casque, la plage est de +10 ~ –
36dB.
2Egalisation HIGH, MID, LOW (3 bandes)
Ces boutons commandent l’égalisation de l’aigu, du moyen et du grave aux
fréquences suivantes.
HIGH: 12kHz, effet maximum ±15dB
MID: 2.5kHz, effet maximum ±15dB
LOW: 80Hz, effet maximum ±15dB
Lorsque le bouton se trouve en position centrale, la courbe de réponse sera
plate.
3Commandes AUX 1, 2
Ces boutons contrôlent le niveau du signal qui alimente les bus AUX. Comme
AUX1 se trouve avant le curseur de canal, il ne sera pas touchépar la position
de ce dernier. AUX2 est placéaprès le curseur de canal et est donc affectépar
le niveau du curseur de canal. Vous pouvez faire sortir un signal via AUX
SEND 1 ou AUX SEND 2 au lieu d’utiliser les bornes ST OUT: cela vous
ferait des sorties supplémentaires.
4Commande PAN (panoramique)
Ce bouton assigne le signal de chaque canal aux bus STEREO L et R, déter-
minant ainsi l’emplacement stéréo du son.
5Diode PEAK
Cette diode détecte le niveau du signal post EQ (avant curseur). Elle s’allu-
mera en rouge à3dB avant saturation pour prévenir que le signal s’approche
du niveau de saturation.
6Commutateur PFL (canal d’entrée)
Ce commutateur vous permet de contrôler le signal du canal d’entrée àun ni-
veau pré- curseur.Vous pouvez vous servir du casque ou de la sortie
MONITOR OUT pour vérifier le signal d’entrée d’un canal donnéou éliminer
les problèmes posés par un canal.
7Curseur de canal
Ce curseur contrôle le niveau de sortie du signal du canal d’entrée et permet
d’ajuster la balance entre les canaux. Les curseurs des canaux non utilisés
doivent se trouver au minimum.
