NT3 Instruction Manual www.rodemic.
Introduction Thank you for investing in the condenser microphone. NT3 studio Stylish and modern, the NT3 is a studio and location workhorse. With both P48 phantom power and condenser internal 9V battery operation, this microphone is at home anywhere.

Features • True condenser externally biased ¾” capsule • Dual power operation • Cast metal body with durable satin-nickel finish • Transformerless output • Internal capsule shock mounting • Internal shock mounting system • High level of RF rejection • Designed & manufactured in Australia • Full 10 year warranty* Powering the NT3 • The NT3 can be powered by either phantom power or 9 volt battery (see specifications).
• The NT3 features a handy power indicator light to help notify you when the battery is running low. L.E.D. SINGLE FLASH – When the L.E.D. flashes (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 reduced when operated with a low battery.
To fit the battery: 1. Unscrew the lower section of the body to reveal the battery cavity. Unscrewing NT3 body 2. Flip open the battery clip so that it doesn’t interfere with loading the battery. 3. Insert the battery into the cavity, inserting the bottom first. Take note of the plus and minus symbol on the floor of the battery cavity to ensure the battery is positioned the correct way. Inserting the battery 4. Push the battery into place so that it is parallel with the top of the cavity.
Using the NT3 • A stand mount clip (RM3) is included with your NT3, and should be used to connect the NT3 firmly and safely to a stable microphone stand. • Always use a high quality microphone cable and ensure that it is wired Pin 1 screen, Pin 2 (+), Pin 3 (-). You may of course use XLR-XLR, XLR-jack or XLRmini-jack depending on your input socket. • We recommend that any connections made to the mixer or recorder are made with the attenuation (gain) set to OFF.
• Changing the acoustic properties of the space around the microphone is our recommended initial approach for obtaining best sound quality. Remember you cannot change a room’s acoustic properties with EQ. When the preferred sound has been achieved (as above) then EQ and effects such as reverb or indeed any signal processing can be used for enhancement, but should be used sparingly.
• The low frequency of the NT3 extends to below 20Hz which is an attractive quality for most recording situations, however in a live situation you may wish to reduce these frequencies when using it as a vocal mic. If you have a high pass filter/bass roll-off then switch it in. Alternatively try moving the microphone away from the sound source (out of the proximity effect). This basic microphone control/technique should be practiced to ensure that the best possible results are achieved.
Storage • After use the NT3 should be removed from its stand mount, wiped with a dry, soft cloth and placed in its protective zip pouch with the supplied moisture-absorbent crystals. • Be sure to place the moisture-absorbent crystals (supplied) at the head of the microphone(s), so as to absorb any moisture present. Eventually this pack of crystals will need to be dried. This is indicated by the crystals turning pink in colour.
Warranty All microphones are warranted for one year from date of purchase. You can extend that to a full ten years if you register the microphone online at www.rodemic.com. The warranty covers parts and labour that may be required to repair the microphone during the warranty period. The warranty excludes defects caused by normal wear and tear, modification, shipping damage, or failure to use the microphone as per the instruction guide.
