Please observe the following:-

After Sales Modifications.

Modifications to this equipment by any party other than Calrec Audio Limited may invalidate EMC

and safety features designed into this equipment. Calrec Audio Limited can not be liable for any

legal proceedings or problems that may arise relating to such modifications.

If in doubt, please contact Calrec Audio Limited for guidance prior to commencing any such work.

ESD (Static) Handling Procedures.

In its completed form, this equipment has been designed to have a high level of immunity to static

discharges. However, when handling individual boards and modules, many highly static sensitive

parts are exposed, therefore in order to protect these devices from damage and to protect your

warranty, please observe static handling procedures (e.g. use an appropriately grounded anti-

static wrist band).

All modules and cards should be returned to Calrec Audio Limited in anti-static wrapping.

Calrec Audio Limited can supply these items upon request, should you require assistance.

This applies particularly to digital products due to the types of devices and very small geometries

used in their fabrication, analogue parts can, however, still be affected.

INTRODUCTION

The Calrec M3 is a high quality, mixing console which provides superior audio and operational

performance in a choice of compact packages. It’s ease of use makes the M3 ideal for novice

operators as well as those who can make full use of the wealth of facilities provided. As with all

Calrec products, the M3 has been designed for long life in real world environments, and offers

high levels of reliability and excellent return on investment.

By combining sophisticated circuit designs with the latest construction techniques, the M3

provides comprehensive features which meet the increased demands of broadcasters for small

format mixers. With mix-minus facilities on every channel, mono and stereo auxiliaries, routing

to four groups and two main outputs with a comprehensive monitoring system, the M3 offers all

that is required of a high performance broadcast mixing console . High input headroom

combined with excellent noise figures means there is no sacrifice in audio performance which

is so often the result on location, or in space restrictive installations.

The M3 enables Broadcasters to meet the operational needs required from small installations

without compromise and with the highest level of confidence in performance and reliability.

1.0 Installation

...................................................................................................................................................................................

INSTALLATION

Some of the checks shown below may seem obvious or unnecessary, but they are essential and

do not take long to complete. If at any time during the proceedings there is anything that you

do not understand, please contact our Customer Support Team who will be happy to help

you with any queries or problems you may have.

• Unpack the mixer (& external power supply, if applicable), checking that all items are present

& undamaged

• Complete the user registration form

• The M3 has the internal switching options set as requested in the customer questionnaire.

If the questionnaire has not been submitted, then the console will be set to the standard

default DIL switch settings shown in section 5. If however this is not the preferred set-up,

then please refer to section 5, which explains the options available using the DIL switches.

• To change the settings, you will need to remove the module from the chassis. Lift off the

graffiti strip & remove the 2 module fixing screws which are located at the top and the bottom

of the module front panel, please do not remove the fader fixing screws. Use the extractor

tool supplied with the console to place into the extraction hole on the front panel & carefully

lift out the module. Please take care not to accidentally knock the module against any of the

adjacent ones as this could result in component and/or front panel damage.

• Using the information in section 5, reset the DIL switches located on the individual module

printed circuit boards (PCBs) to obtain the required set-up. Incorrect selection of DIL

switches can result in severe distortion of audio.

• Visually check the pins in the edge connector for damage, prior to carefully replacing the

module, pushing it firmly & squarely into the mating connectors in the chassis.

• If the mixer has an upstand, use the power & audio leads to connect the upstand inputs to

the appropriate connectors on the rear of the main chassis

• Check that the AC voltage marked on the back of the power supply matches the local

mains supply. If an internal power supply (PSU) is fitted, check the voltage detail on the

console itself. The information can be found adjacent to the Mains IEC input connector,

underneath the console.

• If the console has an external PSU, connect the DC cable from the power supply to the

console and an earthed mains lead to the PSU. Switch on the mains supply & power up

the console, checking that all the LED’s illuminate on the PSU.

• If an internal supply is being used then simply connect an earthed mains cable into the

IEC socket on the console.

• Finally check through the audio paths & connect the console into the rest of the audio

system.

NB It is important to remember that if a module is to be refitted into a powered-up

chassis, all the connector pins should connect into the chassis socket concurrently to

avoid component damage.

...............................................................................................................................................................................

MOUNTING THE M3

The M3 console has been designed to allow for maximum flexibility of use, in that it can be placed

into a site for temporary operation, or fixed into a permanent location.

All console chassis sizes have been designed to allow for mounting in several different ways, as

follows:

•Directly on top of a table top or small equipment rack/trolley.

•Vertically into equipment racking, when chassis is fitted with side support angles* .

•Horizontally into equipment racking, when chassis is fitted with side support angles* .

•Alternatively, the chassis can be ‘dropped through’ the control surface for a permanent

location. The console can either be supported along its lower edge, or from a pair of side

support angles*.

•On a factory supplied stand (Large Chassis only).

* Small and Medium chassis sizes only.

NB. During both Installation & operation, care must be taken to ensure that the ventilation holes

are not blocked & that adequate ventilation is supplied to these areas.
