Audio-Technica (iron triangle) BP4027 stereo super pointing microphone
Audio-Technica (iron triangle) BP4027 stereo super pointing microphone
Features:
Designed for broadcast, film and television and recording. Be
Small and lightweight structures are ideal for camera pendants. Be
Built-in independent hyperignity, and 8-glyph directive radio. Be
There is a high pass filter switch to effectively reduce the low frequency noise in the environment. Be
The non-matrix M-S mode can be selected, or the left and right stereo mode of the two built-in matrices can be selected.
Product Description:
The BP4027 is applied to professional radio work, and the 11V to 52V phantom is available on the 2nd and 3-pin output terminals of the two groups of XLR3M. You can use the phantom power supply on the mixer, you can also use the iron triangle AT8801 single channel or AT8506 Four-channel phantom power supply is independently powered. Be
The low impedance balanced audio output, the audio signal outputs the 2nd and 3rd of the mission output terminal of the mission of the mission, and the first pin is a grounding (shield) connection. The output phase will be placed on the 2rd pin at a positive phase level. If connected to non-balanced equipment, it is necessary to use high quality balance conversion transformers. Be
The microphone is in line with the RoHS specification, which does not contain an EU-disabled hazardous substance. Be
Middle-channel / side channel operation: In the M-S mode, the BP4027 microphone provides separate interonic and silent signals, which can be flexible and broadly stereo image modulation during the field matrix tuning or in the later production. Be
Matrix stereo operation: BP4027 microphone built-in stereo matrix setting, providing conventional left-right channel stereo signal output without special configuration of matrix tunner. To match different audiovisual environments, the microphone has a wide point of stereo matrix and narrow-directed stereo matrix selection, providing a wide or fine audio-visual environment. The output phase will be placed on the 2rd pin at a positive phase level. Be
To achieve the correct left and right stereo positioning, you need to turn down the "UP" text on the microphone downward. In all modes, BP4027 should be proximate to the sound source to reduce echo reverberation and improve stereo radio. The stereo image and increase the "room echo" reverberation when staying away from the sound source.
