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.
