Precautions

1. Avoid excessive heat, humidity, dust and vibration

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.

2. Ventilation

The unit has ventilation slots on the top, rear and bottom panels. Do not block these vents.

3. Avoid physical shocks, liquid and small metal objects

Strong physical shocks to the unit can cause damage. Handle it with care.

Do not place a container with liquid or small metal objects on top of this unit. Liquid or metal objects inside this unit are a ﬁre and electrical shock hazard.

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.

MC32/12, MC24/12—Owner’s Manual

Introduction

Thank you for choosing the Yamaha MC32/12 or MC24/12 mixing console. Please read this manual thoroughly to take best advantage of the console and extend its useful life.

Notes:

This manual has been written on the assumption that you already understand the basic operation and technical terminology of mixing consoles.

Descriptions of MC24/12 speciﬁcations appear in brackets ({}) if they differ from the MC32/12.

Features

Introduction

• The MC32/12 provides 28 monaural and 2 stereo input modules {the MC24/12 provides 20 monaural and 2 stereo input modules}. The output channels comprise stereo outputs, 10 mix outputs, and two matrix outputs, and support a wide range of applications, from SR (sound reinforcement) to facility acoustics.

• Each monaural input channel offers a 26 dB pad, HPF, phase switch, 4-band EQ (HI-MID and LOMID frequencies are variable), and a 100 mmlong full-stroke fader. Also, phantom power can be turned on and off for every group of four inputs.

• Four stereo AUX returns and TAPE IN jacks are provided as standard.

• The master section of the console is located in the center area of the unit, facilitating operation.

• The master section provides output channels for MIX buses 1–10, with EQs and 100 mm-long faders.

• Each input channel and four stereo AUX returns include a PFL switch, and stereo bus, MIX buses 1–10, and Matrix 1–2 has an AFL switch, enabling you to monitor the input/output sources quickly.

This routing can be used as a conventional group bus. In this way, you can conﬁgure the bus for a speciﬁc purpose.

• The console has two independent matrixes. You can mix MIX buses 1–4 and the stereo bus individually at the levels you desire and output them from the MATRIX OUT 1–2 jacks. This routing can be used as a mix for the foldback or for individual speakers and ampliﬁers.

• The INSERT I/O jacks are provided for all monaural input channels, the stereo bus, and MIX buses 1–4. You can insert an external effect processor, if necessary.

• Talkback signals can be sent to any of MIX buses 1–4, MIX buses 5–10, and the stereo bus.

• C-R monitor output enables you to select PFL/ AFL or TAPE IN as a monitoring source.

• The console’s sturdy ﬁnish and rugged design assure its durability even under severe conditions and rough on-site usage.

• Using the GA Diversity function enables you to set MIX buses 1–4 to Variable mode or Fix mode individually. In Variable mode, you can change the level of the signals sent out from the input channels. This routing can be used as a conventional AUX bus. In Fix mode, the level of the signals sent out from the input channels is ﬁxed.

GA Diversity Function

What is GA Diversity?

GA Diversity is an output select function that allows you to use the MIX OUT jacks as group output jacks or AUX output jacks on the MC32/12 and MC24/12.

You can route either MIX (Variable) bus signals or MIX (Fix) bus signals to the MIX OUT 1–4 jacks of the MC32/12 and MC24/12. You can select either one of these output signals in the Variable/Fix select section.

If the M1–M4 switches in the Variable/Fix select section are set to FIX ( ), the corresponding MIX OUT jacks will output MIX (FIX) bus signals. Since each channel’s output level for the MIX (FIX) bus signals is ﬁxed, the corresponding MIX OUT jacks will function as group output jacks.

If the M1–M4 switches in the Variable/Fix select section are set to VARIABLE ( ), the corresponding MIX OUT jacks will output MIX (VARIABLE) bus signals. Since each channel’s output level for the MIX (VARIABLE) bus signals is variable, the corresponding MIX OUT jacks will function as AUX output jacks.

The GA Diversity function will enable you to conﬁgure a ﬂexible bus system, such as four groups and six AUX sends, two groups and eight AUX sends, or 10 AUX sends, etc., depending on the application.

Setting the GA Diversity function

1. Press down the M1 switch ( FIX) in the Variable/ Fix select section (see page 6).

The FIX indicator will light up. The MIX OUT 1 output channel will receive the MIX (FIX) 1 bus signal, and the MIX OUT 1 jack will function as a group output jack.

2. Press the M1 switch again to set it to ( VARIABLE).

The FIX indicator will be turned off. The MIX OUT 1 output channel will receive the MIX (VARIABLE) 1 bus signal, and the MIX OUT 1 jack will function as an AUX output jack.

3. Set the M2, M3, and M4 switches in the same way.

You can set MIX OUT 1–4 channels to “FIX” or “VARIABLE” individually.
