EUDAC AUDIO KM-100 Plus Digital Amplifier

EUDAC AUDIO KM-100 Plus Digital Amplifier is a line of mechanical reverbs that is redefining the standard for high-end karaoke mechanical reverbs, with superior sound processing capabilities, intelligent anti-feedback and high-quality Bluetooth aptX connectivity. This is the ideal device for home karaoke systems, semi-professional studios and small stages, where clean, musical sound and flexible customization are required.

Outstanding technical features of EUDAC AUDIO KM-100 Plus

The most outstanding feature of the KM-100 Plus is the ability to adjust echo and reverb separately, allowing users to fully control the depth and flight of the sound effect. The echo is not too long or harsh, the reverb is sweet and warm, very suitable for karaoke vocals.

The device also integrates up to 8 different effect modes, and allows separate treble, mid, and bass adjustment for both the music and microphone parts - something that many other mechanical echo models do not have.

In particular, the KM-100 Plus is equipped with a 3-mode feedback suppression system, which effectively handles howling, even when using high-power wireless microphones in closed spaces. In addition, the audio processor on the device also achieves an extremely low THD of only 0.03%, ensuring clean and faithful audio signals.

Connectivity and compatibility

In terms of connectivity, the KM-100 Plus stands out with the Bluetooth aptX standard, allowing high-quality wireless audio transmission while still ensuring detail and clarity.

In addition, the device also fully supports connection ports such as AUX, USB, RCA, making it compatible with many devices such as phones, TV boxes, karaoke players, amplifiers, and high-power speakers. The input sensitivity of the microphone is 6mV/4kΩ and AUX is 280mV/30kΩ, helping the device receive stable signals even at low volume levels.

The device works well with many types of full-range speakers, powered subwoofers and wireless microphones - creating maximum flexibility in installing and upgrading home audio systems or mini stage systems.

Sound processing and effects

EUDAC KM-100 Plus is highly appreciated for its extremely delicate sound processing ability. The microphone frequency response from 40Hz–15kHz ±6dB ensures that vocals are reproduced clearly, without being overwhelmed by background music, while the music has a wider frequency range, from 20Hz–20kHz ±3dB, expressing both deep bass and bright treble.

The device allows fine-tuning each frequency range: bass ±10dB, mid ±6dB, treble ±10dB - applied separately for both music and microphone, very useful in customizing sound quality according to space or personal preferences. This is one of the few cheap mechanical echoes but has the ability to process detailed signals, almost approaching the digital echo line in the same segment.

Compare with similar products

Compared to other mechanical reverb devices in the same segment such as Jarguar Suhyoung PA-203N or BTE K-6, KM-100 Plus is superior in its three-level anti-feedback capability, separate EQ adjustment for mic and music, as well as integrated Bluetooth aptX standard - a very rare factor in mechanical reverb lines.

Many competitors only support simple echo and do not have EQ adjustment according to frequency range, leading to the sound quality being easily "distorted" in spaces with poor acoustics. Meanwhile, the KM-100 Plus brings a more realistic experience thanks to its clean, stable signal processing and easy mixing.

The price of this product is also at an accessible level, creating a great advantage for ordinary users who want to upgrade sound quality without having to invest in complicated digital reverbs.

Instructions for effective use

To use the KM-100 Plus effectively, you should start by connecting the audio devices according to the correct standards - prioritize using signal cables with suitable and sturdy impedance. After powering up, adjust the bass, mid, treble ranges for the music and microphone separately.

For a space of 20-30m², you should set the echo to medium, increase the reverb slightly to create a floating effect, and activate the appropriate anti-feedback mode. If the space is prone to echoes, you should use anti-feedback mode level 3. In addition, you should also periodically check the jack, adjust the total volume appropriately (avoid clipping the output signal) and clean the device to ensure the sound is always in optimal condition.

Reviews from users

Many users in Vietnam rate the KM-100 Plus as the “smoothest” mechanical reverb under 3 million, especially in its ability to echo easily, sweet reverb, and effective anti-feedback in closed spaces. Feedback on e-commerce platforms shows that the 4-5 star rating accounts for more than 85%, with plus points being “clean sound, easy adjustment, clear vocals”.

Some users also compared it with digital echo and said that KM-100 Plus is enough for both family karaoke rooms and small stage spaces, especially when combined with full bass 25 or sub 30 speakers. After-sales service from Phuc Truong Audio is also praised for its enthusiastic advice and quick technical support, creating great trust for customers who have chosen this product.

FAQ

Does EUDAC AUDIO KM-100 Plus have good anti-feedback?

Yes. The KM-100 Plus is equipped with 3 anti-feedback modes to effectively eliminate feedback when using the microphone at high volume or in closed spaces. This is a rare feature in the same price range of mechanical echoes.

Does the KM-100 Plus have separate echo and reverb controls?

Yes. This is one of the most outstanding features of the product. Users can adjust echo and reverb completely independently, thereby creating deep, smooth, easy-to-control vocals without overlapping effects.

Does this mixer have Bluetooth connectivity? Is it stable?

Yes, using Bluetooth aptX standard - helps transmit high quality wireless audio, low latency and retains good sound details. This is an outstanding point when compared to many other popular mechanical echo lines that only use regular Bluetooth.

What square meter room is this product suitable for?

With powerful amplification and good sound processing, the KM-100 Plus is suitable for rooms family karaoke system from 15–35m². If combined with full speaker 25 bass or 30 subwoofer, can be used for both mini stage or small open space.
