The Rode NTG-2 is a condenser shotgun microphone designed for professional audio capturing in the field or indoors. With a history of manufacturing quality studio microphones, Rode has implemented low noise output electronics and wide bandwidth, both of which attribute to the NTG-2's broadcast sound quality. The super-cardioid polar pattern and line plus gradient acoustic principle effectively minimize audio and noise at the off-axis (sides) of the microphone, while the front of the capsule accurately reproduces incoming audio signal. The result is greater intelligibility and signal-to-noise ratio when using the NTG-2 in noisy environments. The NTG-2 is powered with an internal 1.5V AA size battery or an external 48 Volt phantom power source. The output is a standard 3-pin XLR male connector. The microphone features a rugged, all metal, lightweight enclosure that is ideal for camera mounting yet durable enough to withstand the rigors of heavy road use. The Rode NTG-2 is packaged with a microphone stand mount and windscreen. Battery Or Phantom Powered The Rode NTG-2 can be powered with an internal 1.5V AA battery or external 48V phantom power source. Super-Cardioid Polar Pattern The super-cardioid polar pattern and line gradient acoustic principle allow for a narrow pick up pattern at the front of the capsule while minimizing noise at the off-axis sections. Lightweight Durable Construction The NTG-2 features a lightweight metal housing that is ideal for camera mounting. Low Handling Noise Low noise output electronics provide high signal-to-noise ratio. The NTG-2 is designed to also reduce noise caused by handling, rigid mounting hardware, loose cabling etc. Specifications Transducer Condenser Polar Pattern Supercardioid Frequency Response 20Hz to 20kHz Sensitivity -36.0dB re 1 Volt/Pascal (15.00mV @ 94 dB SPL) /- 2 dB @ 1kHz Signal-to-Noise Ratio 76dB (1kHz rel, 1Pa; per IEC651, IEC268-15) Maximum Input Sound Level 131dB SPL (@ 1kHz, 1% THD into 1K? load) Power Requirements 48V phantom, 44V to 52V Output Impedance 250?

Q2, Q3 when the composition of the detection circuit, the circuit normally oscillate voltage AC voltage exceeds 0.6V, Q2 will be in the negative half cycle of conducting the C4 discharge short circuit, resulting in Q3 ends; when it detects metal objects near the coil L1, will be metal conductor eddy current is generated, the oscillation circuit of the energy loss increases, positive feedback weakened in the critical state of the oscillator weakened, if not impossible to maintain the minimum required energy oscillations and to stop, so Q2 is turned off, R2 to C4 charge, Q3 is turned on, pushing the buzzer sounds. According to whether the sound, you can determine whether the detection coil underneath the metal object. Note: If you need longer detection range and higher sensitivity, please create their own search coil, search coil diameter of the larger suppliers will be farther away from the probe.

Feature: Supply voltage: 3-5V Dimensions: 66 x 61MM Maximum measure range: 5CM (Best measure range: 1 CM - 2 CM) Principle explanation: Q1, L1, L2, C2, C3, R1, W composed of high-frequency oscillation circuit, adjustment potentiometer W, you can change the oscillation stage gain, the oscillator oscillating in a critical state, that is just the oscillator start-up. Q2, Q3 when the composition of the measure circuit, the circuit normally oscillate voltage AC voltage exceeds 0.6V, Q2 will be in the negative half cycle of conducting the C4 discharge short circuit, resulting in Q3 ends; when it measure metal objects near the coil L1, will be metal conductor eddy current is generated, the oscillation circuit of the energy loss increases, positive feedback weakened in the critical state of the oscillator weakened, if not impossible to maintain the minimum required energy oscillations and to stop, so Q2 is turned off, R2 to C4 charge, Q3 is turned on, pushing the buzzer sounds. According to whether the sound, you can determine whether the measure coil underneath the metal object. Note: If you need longer measure range and higher sensitivity, please create their own search coil, search coil diameter of the larger suppliers will be farther away from the probe Package included: 5 x DIY Metal Measure Kit
