NT4 Instruction Manual www.rodemic.
Introduction Thank you for investing in the NT4 stereo condenser microphone. The NT4 solves the age-old problem of stereo recording by eliminating the need to purchase matched pairs and the associated complex set-up bars and adaptors to get professional results. With a fixed 90 Degree X/Y configuration and perfectly matched stereo condenser capsules, the NT4 lets you record any source with immaculate stereo detail. The NT4 has a 128 dB dynamic range, 143 dBA SPL and low self-noise.
Specifications Acoustic Principle: Pressure gradient Directional Pattern: Cardioid (per capsule) (see graph) Frequency Range: 20 Hz - 20 kHz (see graph) Output Impedence: 200 per side Sensitivity: -38 dB re 1 Volt/Pascal (12 mV @ 94 dB SPL) +/- 2 dB @ 1kHz Equivalent Noise: <16 dB SPL (A - weighted per IEC651) Maximum Output: +13.

Accessories RM3 Stand mount RC4 Case WS4 Wind shield NT4-DXLR stereo XLR lead NT4-MJ XLR to 3.5mm stereo cable Powering the NT4 • The NT4 can be powered by either phantom power (see specifications) or a 9V battery. • 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 fitted into the cavity within the microphone body ensuring correct polarity (+ to + and - to -).
Powering the NT4 • 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. If left ON, the battery power will be unnecessarily depleted. • We recommend that during long periods of nonuse, the battery should be removed, as it may leak and that could damage your NT4. • If a battery is installed but phantom power is available, current will not be drawn from the battery.
Connecting the NT4 • The NT4 is supplied with both a dual XLR cable (NT4-DXLR), and a stereo mini-jack cable (NT4-MJ). • The NT4 may be connected directly to two channels of a mixer using the twin XLR cable (marked L and R) supplied, with each channel panned left and right as required. Connection may also be made direct to a portable recording device to enable field/location operation using the 9V battery supply.
Using the NT4 • The NT4 is an easy to use, precision stereo condenser microphone. Choirs, orchestras, drum over-heads, solo or ensemble instruments, and many other situations may all be recorded with the ambience and ‘space’ that 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.
• Sound quality is of course subjective and ‘your sound’ will be achieved by experimenting. We suggest that you begin with EQ set FLAT/OFF (no boost or cut). • Remember that EQ cannot change the acoustic properties of a room. In a studio 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 also has dramatic effect on the sound quality.
Using the NT4 about the angles of two individual microphones, or testing to see if they are two of the same model which sound a little different to each other. • Choir/Vocal group: Placement can be in front of the vocalists with the microphone pointing towards the middle of the group. The distance between the vocalists and the microphone depends on the acoustics of the environment, level of the vocalists and the sound that you are trying to achieve.
Using the NT4 • Location recording: When using the NT4 outdoors, care must be taken to avoid excessive handling noise and wind noise. As with all condenser microphones, the NT4 is sensitive to strong gusts of wind and so should be adequately shielded. The supplied wind shield (WS4) is designed for vocal applications and indoors only. The WS4 is typically not effective enough outdoors in high wind conditions – in this instance we recommend the optional RØDE Dead Kitten furry windshield.
Warranty All microphones are warranted for one year from date of purchase. You can extend that to a full ten years if you register 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.
