Feature 1High Gain of 28dB: When combined with a sound card and microphone, the in line mic preamp provides a pure gain of 28dB, effectively boosting the voice signal and making post processing of sound more seamless. 2Lossless Amplification: The microphone preamp's gain effect minimally affects the original sound quality, while also reducing the noise issues that may arise from excessive gain in the sound card itself, ensuring a worry free experience. 3Plug and Play: Simply connect the microphone preamp to the mixer, and power it using the 48V phantom power supply from the microphone input on the sound card. This provides a fixed gain volume of 28dB. (Note: The preamp may drain the 48V phantom power, so it is not suitable for capacitor microphones that require phantom power.) 4Stylish and Durable: With a sturdy matte metal casing, the microphone preamp boasts a stylish and minimalist design. It is compact, lightweight, and portable, making it convenient to carry around. 5Versatile Applications: Ideal for studio recording, live news broadcasting, stage performances, large scale speeches, home entertainment, musical instrument playing, and other scenarios.Item Type: Inline Microphone PreampMaterial: Aluminum AlloyWeight: Approx. 60g/2.1ozGain Boost: 28dBConnector: XLR 3 Pin Male/FemalePower Supply: 48V According to IEC 61938Frequency Range: 10 to 120000HzImpedance: 135 OhmsRecommended Impedance Electronic Load: >1k OhmsSampling Rate: 24 Bit/48kbps SoundSignal to Noise Ratio: 3.0mAOutput Noise: 9uV (JIS A)Maximum Input Level: 8.3dBV/2.6V (0.5% THD) .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Package List1 x Microphone Preamp1 x User Manual
