• All-in-One FM Tuner: Enjoy the convenience of an FM tuner, preamp, and headphone amplifier all in one device. Streamline your setup, enjoy crystal-clear FM broadcasts, and adapt seamlessly to preamp or headphone mode to fit your audio needs.  

• Global FM Compatibility: With the American SI4831 radio chip, it supports three selectable frequency ranges: 64-87MHz, 76-90MHz, 87-108MHz, offering global compatibility. Enjoy easy, one-touch frequency switching for seamless reception.

• Flexible Preamp & Headphone out: With AUX input, it seamlessly connects to CD players, phones, and laptops etc., use it as a preamp for your power amp / active speakers, or enjoy private listening through the TPA6132 chip, offering dynamic sound with minimal noise.  

• Shape Your Ideal Sound: With dedicated bass and treble knobs, you can easily tailor your audio to perfection. Enhanced by dual NE5532 op-amps and precision components, the M08E delivers rich and detailed audio.  

• Mini Size, Built to Last: Compact yet durable, the M08E features a solid aluminum alloy body that ensures long-term reliability. With mute/unmute, clear status indicators, and intuitive controls, it delivers everyday convenience for any audio system.

Q: Why is the FM signal weak?
A: Poor FM reception may be caused by interference or location. Please keep the M08E away from potential sources of electromagnetic interference and place it near window or in an open area for better signal.   Q: How to improve FM tuning and reception?
A: Please adjust the antenna’s position patiently to find the strongest signal, and try placing it in different locations to optimize reception.     Q: What is the default mode when powered on? How to switch to AUX?
A: M08E defaults to FM mode. When an AUX cable is plugged in, it automatically switches to AUX input mode.   Q: Does M08E support auto search and station memory?
A: No. M08E only supports manual tuning.   Q: Are the NE5532 op-amps pluggable? A: No. They are soldered directly onto the board and cannot be replaced or swapped out. Parameters
