Introduction Congratulations on purchasing the M3 microphone. The M3 was created to allow you to achieve the very best results from both live performance and in the studio. One of the key features of the M3 is that it has been designed with a switchable PAD and high pass fi lter, which gives you greater control of the sound source. It is battery operated to allow versatility with locations as well as being manufactured in a sleek contemporary black design. Please take time to read through

Contents M3 Microphone Carry Case Pop Shield RM3 Mic Clip Powering the M3 The M3 is suitable for a wide range of applications. Recording, stage, and location work are all well within the capabilities of this microphone. Its low noise and full frequency response ensure the sound quality is at a standard that is expected by today’s musicians and engineers. You may use either phantom power (see Specifi cations - page 3) or 9V battery to operate your M3. Phantom power (P48 & P24) Most professi

To connect an XLR cable; 1. Before you connect your mic, ensure that the XLR cable you are using is wired correctly to match the output pins on the M3. The M3 offers a balanced microphone level output and is wired as follows: Pin 1 (earth), Pin 2 (+) and Pin 3 (-). XLR KEYWAY PIN 2 (+) PIN 3 (-) PIN 1 (EARTH) Figure 1 - XLR jack You may of course use XLR-XLR, XLR-jack, or XLR- mini jack plugs depending on your relevant input socket. 2. Make sure you use a high-quality, low-loss XLR

Battery power (9 volt) If phantom power is not available on your equipment, you will need to use battery power. To use battery power, a 9 Volt (PP3) battery should be fi tted into the cavity within the microphone body ensuring correct polarity (+ to + and - to -). We recommend that you use a high quality alkaline battery. Tests have shown a life expectancy for a high quality alkaline battery used in the M3 to be in excess of 300 hours. This is roughly the equivalent of 6 hours usage per

Figure 4 - Inserting the battery 4. Push the battery into place so that it is parallel with the top of the cavity. Secure the battery in place by fl ipping the battery clip over so that it sits on the battery. 5. Reassemble the body, screwing lower section fi rmly together with the upper section. - 8 -

Operating the M3 The M3 may be connected to a mixer (recording or live), and battery power will only be required if the mixer does not have an in-built phantom P48 or P24 supply. Connection may also be made direct to a portable DAT or other tape machine enabling fi eld/ location operation using the 9V battery supply. The M3 microphone has both a PAD switch and a Filter switch. On/Off Filter switch The fi lter switch is a multifunctional three position switch. It will control main power (fr

L.E.D. SINGLE FLASH – When the L.E.D. fl ashes (illuminates for around one second), the battery power is ‘good’. This indicates that the microphone has just been powered. L.E.D. STAYS ON – When the L.E.D. light illuminates continuously the battery power is getting low. Please replace the battery as soon as possible, as the microphone’s sensitivity is greatly compromised when operated with a low battery. Note: When using M3 on battery power, it is a good idea to keep the microphone in the

Mounting the M3 A stand mount clip (RM3) is included with your M3 and should be used to connect the M3 fi rmly and safely to a stable microphone stand. How to attach the stand mount 1. Before placing the M3 into the RM3 stand mount, remove all cables and connectors to eliminate the possibility of damaging the connectors. 2. Place the M3 into the RM3 by inserting the mic on an angle (fi gures 8 & 9). Figure 8 - Microphone mounting Figure 9 - Microphone mounting You will notice the holder is qu

Recommended Initial Setup Now that you have the M3 securely fastened to a mic stand or tripod, and the audio output XLR connected, you are ready to fi ne tune your setup. 1. When fi rst switching the mixer on and phantom power is applied to the M3, or when the microphone battery power is switched ON, several seconds should be allowed for the microphone to stabilize. We recommend that all connections made to the mixer or recorder are made with the attenuation (gain) set to OFF (0db). 2. To

The best way to assess your recording environment is to listen to the sound you wish to record acoustically fi rst. Remember that no amount of EQ can correct a ‘bad’ recording environment. Any further desired modifi cation of sound can then be undertaken with the EQ and effects. 4. Live/Stage Use: As a live vocal mic, the M3 offers studio-quality sound on stage, which is not achievable with a dynamic microphone. A characteristic of most dynamic vocal microphones is that their ‘full freque

Care and Maintenance 1. Like all electret condenser microphones, the M3 should be kept dry at all times. The capsule will be potentially subject to moisture during vocal use, and we strongly recommend the use of the foam windscreen (supplied with your M3) during all vocal applications. This screen will also minimise plosives (the high sound pressure levels of pronounced B’s and P’s which can bottom-out the capsule). 2. Although the M3 is a well-built, durable microphone it is subject to
