The PROAUDIO P665 is a cardioid condenser microphone designed for professional sound recording. It is suitable for various recording situations, emphasizing quality, reliability, and precision in sound capture.

Function Description:

The P665 is a cardioid condenser microphone primarily intended for musical instruments. Its cardioid polar pattern makes it effective at capturing sound from the front while rejecting sounds from the sides and rear, which is ideal for isolating a specific sound source in a recording environment. This makes it particularly well-suited for applications such as recording acoustic guitars, hi-hats, choirs, pianos, and string instruments. The microphone's design aims to provide an essential reference point for sound recording professionals due to its focus on high-quality audio reproduction.

Important Technical Specifications:

Polar Pattern: Cardioid
Frequency Response: 40Hz - 20kHz, offering a wide range to capture both low and high frequencies accurately.
Max SPL (Sound Pressure Level): 130 dB, indicating its ability to handle high sound levels without distortion.
S/N Ratio (Signal-to-Noise Ratio): 60 dB, suggesting a good ratio of desired signal to background noise, contributing to clear recordings.
Power Supply: 9V - 52V, indicating it requires phantom power, which is typical for condenser microphones.
Output Impedance: 250Ω ±30% (at 1KHz), a standard impedance for professional audio equipment.
Sensitivity: -51dB ±3dB (at 1KHz), reflecting its efficiency in converting sound pressure into an electrical signal.
Measures (WxHxD): 35x167x22mm, providing its physical dimensions.
Weight: 210g, indicating a relatively lightweight and portable design.

The frequency response graph illustrates a generally flat response across the audible spectrum, with some minor variations, suggesting a natural and uncolored sound reproduction. The polar pattern diagram, measured at 1000 Hz, clearly shows the cardioid characteristic, with maximum sensitivity at 0 degrees (front) and significant attenuation at 180 degrees (rear).

Usage Features:

Recommended Use: Specifically designed for musical instruments, including acoustic guitars, hi-hats, choirs, pianos, and string instruments. This versatility makes it a valuable tool in a studio or live sound setting.
Excellent S/N Ratio and Wide Frequency Response: These features ensure that the microphone captures sound with clarity and detail across a broad spectrum, minimizing unwanted noise.
XLR Connection: The industry-standard XLR connector ensures compatibility with professional audio interfaces, mixers, and preamplifiers that provide phantom power.
Included Accessories: The microphone comes with a stand adapter, which facilitates easy mounting on microphone stands for optimal positioning during recording or performance.

Maintenance Features:

While the manual does not explicitly detail maintenance procedures, the device's robust construction and professional-grade components suggest a durable product. The elegant silver finish implies a design that is not only functional but also aesthetically pleasing, likely requiring standard care for electronic equipment, such as keeping it clean and protected from physical damage or extreme environmental conditions. The CE mark indicates compliance with European health, safety, and environmental protection standards, and the "MADE IN PRC" label specifies its country of manufacture. The crossed-out wheeled bin symbol signifies that the product should not be disposed of with general household waste but rather through designated collection facilities for electrical and electronic equipment, promoting environmental responsibility.
