Stand Mount (with 3/8" -5/8"thread adaptor) THE NT3 is suitable for a wide range of applications. Recording, stage, and location work are all well within the capabilities of this hypercardioid condenser microphone. Its low noise and full frequency response ensure the sound quality expected by todays musicians and engineers. [. . . ] Tests have shown a life expectancy for a high quality alkaline battery used in the NT3 to be in excess of 400 hours. * *NOTE: This is equal to 8 hours recording per week for a year (including 2 weeks holidays!!!) 5. The NT3 may be connected direct to a mixer (recording or live) and battery power will only be required if the mixer does not have an inbuilt phantom P48 supply. Connection may also be made direct to a portable DAT or other tape machine enabling field/location operation using the 9V battery supply. 6. A stand mount clip (RM-3) is included with your NT3, and should be used to connect the NT3 firmly and safely to a stable microphone stand. Always use a good quality microphone cable and ensure that it is wired Pin1 Screen, Pin 2+, Pin 3-. You may of course use XLR-XLR, XLR-jack, or XLR-mini jack plugs depending on your relevant input socket. We recommend that all connections made to the mixer or recorder are made with the attenuation (gain) set to OFF. When first switching the mixer ON and phantom power is applied to the NT3, or when the microphone battery power is switched ON, several seconds should be allowed for the microphone to stabilize. Note: When using phantom power, a battery may be in or out; it is ineffective in that situation. To ensure the lowest noise/distortion, your mixer input gain control should be set so that the Peak Program Indicator (P. P. I. ) L. E. D. flashes ON during peaks (high levels) of the program source (Voice/Instrument). If there is no P. P. I. , adjust the input gain while listening for distortion of the sound. As distortion is heard, reduce the gain gradually until the sound is undistorted (clean). Sound quality is of course subjective and ` your sound' will be achieved by you with experimentation. We suggest that you begin with EQ set FLAT/OFF (no boost or cut). Remember the EQ cannot change the acoustic properties of a room. In a recording situation, you should try placing absorbent or reflective panels/material in various positions within the vicinity of the sound source and microphone. The positioning of the microphone can also have a dramatic effect on the sound quality. The best way to assess your recording environment, is to listen to the sound you wish to record acoustically first. Remember that no amount of EQ can correct a ` bad' recording environment. Any further desired modification of sound can then be undertaken with the EQ and effects. As a live vocal mic, the NT3 offers studio-quality sound on stage, which is not achievable with a dynamic microphone. [. . . ] To reactivate them, place the pack in an oven set between 100-150 degrees C until they become blue again. Note: There are no user serviceable parts inside this microphone so there will never be reason for you to dismantle it (except to replace the battery). Any service which may require dismantling must be performed by an authorised RØDE Service Agent. Warranty Service: All RØDE products are warranted for one year from date of purchase and the warranty card should be used to register that purchase. 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. [. . . ]
