Introduction

Congratulations! You are now the proud owner of a Yamaha MM1242 Mixer. Your Yamaha mixing console is a high-quality product which combines ease of operation, functionality, and convenience and will give you superior performance in a wide range of applications. MM1242 also features the great sound for which Yamaha is famous. Please read this operation manual thoroughly in order to make the most of the mixer’s many features and controls.

Features

● Twelve input channels and stereo mix output

● PFL (Pre Fader Listen) function allows you to monitor any channel input and ST L, R AUX

3, 4 output through monitor output or headphones.

● All input channels are available for both microphone level input and line-level input,

making connections very easy.

● Built-in phantom power allows you to connect condenser microphones.

● Four AUX SEND connectors and four ST AUX RTN connectors allow you to connect up

to four external effects units.

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 Modifications 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 disconnecting 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.

4 AUX send controls

Each AUX control determines the level of the signal sent from the input channels to the correspondingly-numbered AUX mixing bus.

• AUX 1 and AUX 2 are factory pre-wired for post-fader operation, so the AUX 1 and AUX 2 signals are affected by the setting of the channel fader.

• AUX 3 and AUX 4 are factory pre-wired for pre-fader operation, so the AUX 3 and AUX 4 signals are not affected by the setting of the channel fader. Therefore, the signal can be output either to AUX 3 or AUX 4 as an auxiliary output, instead of using the stereo outputs.

5 PAN control

The PAN control determines the position in the stereo sound field at which the sound from that channel is heard, by distributing signal from each channel to STEREO L and R buses.

6 PEAK indicator

The PEAK indicator LED lights in red when the pre-EQ, post-EQ, or post-fader signal of the corresponding channel’s input reaches a level 3dB below the clipping level.

7 PFL switch

Press this switch to monitor the pre-fader input channel signal through the MONITOR OUT or the PHONES connector. This is useful when you wish to monitor only the signal

from a particular channel, or take a countermeasure for a problem.

8 Fader

This is the main level control for each input channel. It determines the level of the signal sent from the corresponding input channel to the master stereo bus. The settings of the input channel faders determine the “mix” or balance of sound levels between the instruments or other sources connected to the inputs. Lower the faders of unused channels to the bottom.

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 également 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 transmission.

2. Ventilation

L’appareil est pourvu de fentes d’aération sur les panneaux latéraux et inférieur. Ne bloquez jamais ces fentes.

3. Evitez tout choc

Un choc relativement important peut endommager l’appareil. 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’ouverture 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’appareil correspond bien à celle de votre secteur et que les prises utilisées peuvent assurer le courant nécessaire pour faire fonctionner tout votre système.
