User manual RODE NT4

[. . . ] Choirs, orchestras, drum over-heads, solo or ensemble instruments, may all be recorded with the ` ambience' and ` space' only a true stereo microphone like the NT4 can capture. The two capsules used in the NT4 measure 1/2" in diameter and have a cardioid polar pattern. The cardioid patterns pick-up sound from in front of the microphone and reject sound from the rear. This helps with reducing unwanted sound such as reverberation and audience sound from the rear of the capsules. [. . . ] Ensure that whichever power supply you use, it is a professional unit and is working correctly. If you choose to use battery power, a 9 Volt (PP3) battery should be fitted into the cavity within the microphone body ensuring correct polarity (+ to + and ­ to ­ ). To fit the battery, simply un-screw the lower section of the body and insert the battery into the cavity (terminals first). Secure the battery in place with the flexible spring clip and reassemble the body, screwing the sections firmly together. 4. The ON/OFF switch turns the microphone ON or OFF when powered by either phantom or battery. When using battery power, the switch should be switched to OFF when the microphone is not in use. We recommend that during long periods of non-use, the battery should be removed, as it may leak, and that could damage your NT4. (light-emitting-diode) gives an indication of battery power and should always be carefully observed. flashes (illuminates for about 1 second), the battery power is ` good' . remains illuminated significantly longer, the battery should be replaced. Tests have shown a life expectancy for a high quality alkaline battery used in the NT4 to be in excess of 400 hours. 5. The NT4 may be connected directly to 2 channels of a mixer using the twin XLR cable (marked L and R) supplied, with each channel panned left and right as required. Battery power will only be necessary if the mixer does not have an in-built phantom P48 supply. Connection may also be made direct to a portable DAT or other recording devices to enable field/location operation using the 9V battery supply. A stand mount clip (RM-3) is included with your NT4, and should be used to connect the NT4 firmly and safely to a stable microphone stand unless of course you choose hand-held operation which should only be used when it is not possible to stand mount the NT4. The NT4 is supplied with both a dual XLR cable, and a stereo mini-jack cable. The stereo mini-jack cable and battery option allow for maximum portability and connection to most recording devices. Whether you are using a mixer, DAT player or Mini-disc player (with or without phantom power), the connections and power options allow for maximum flexibility. 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 NT4, 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). [. . . ] To reactivate them, place the pack in an oven set to between 100150 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 authorized Service Agent. Warranty Service: All products are warranted for one year from your date of purchase and the warranty card or on-line registration (www. rodemic. com) should be used to register your microphone.
