Stereo Sound Small Microphone Headphone Phono Turntable Preamplifier for Desktop Sound System with Independent Knob and Power Supply Preamplifier,

【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.

[About clocks that synchronize time via radio waves] The function of clocks that synchronize time via radio waves only works in the Japanese area. Please be careful. 3 ports: The microphone and music are amplified by the stereo sound preamplifier, and then can be output independently or mixed output. There are 3 output ports in total, and the mixed output port can directly drive headphones for listening. Interface Size: The 3.5mm interface of the biased preamp can be used with electret and common condenser microphones, and the 6.5mm interface is a dynamic microphone that can amplify wired and wireless microphones. Amplification time: Dynamic microphone 6.5mm port is amplified 75 times, 3.5mm port condenser microphone is amplified 22 times, stereo music input 3.5mm port is amplified 5 times. Ultra-low noise: The all-aluminum housing of the microphone headphone amplifier completely isolates electrical interference, and the rail-to-rail operational amplifier MC33202 ensures the best sound quality at all output levels with ultra-low noise operation and excellent sound performance, making it ideal for desktops. sound system. Use a good quality low ripple power supply. If the quality of the power supply is poor, hum is more likely to occur. Wide application: Sound mixer with 2 volume control knobs. Mix multiple channels into one rail and be compatible with multiple devices. Ideal for musical instruments, microphones, mobile phones, computers, power amplifier equipment, speakers, small stage settings, drum sets or submixes and other sound devices, with DC5‑12V power supply 5.5 x 2.1mm power hole 1. 3 ports: The microphone and music are amplified by the stereo sound preamplifier, and then can be output independently or mixed output.
