Kinter K3118 2 x 15 watts Digital Audio Amplifier - the perfect choice for nearly every audio listening need.
Kinter K3118 Digital Audio Amplifier - American Designed and Engineered for Versatile Applications Including DIY Projects, Arcade, Home, Auto & More!
Texas at Heart
Inside the Kinter K3118 amplifier is a USA Designed Texas Instruments (TI) TPA3118 Class D audio amplifier IC that provides 2 X 15 watts RMS of highly efficient, detailed audio that's perfect for desktop, workbench, garage, arcade, auto, cycle or DIY projects.
A Versatile Performer
Separate Bass and Treble controls are standard on the K3118 amplifier as are gold-plated RCA left and right inputs along with a 3.5mm jack for plugging in smart phones or other equipment as the audio source. A “Direct” button bypasses the Bass and Treble circuit for listening to unaltered sound. The volume control is surrounded by a blue light indicating the amplifier is on. Connect your 4-8 Ohm speakers using the 14-16 gauge spring-loaded terminals found on the rear of the amp. The small aluminum enclosure keeps the K3118 running cool and has tabs that allow the amplifier to be mounted if required.
Anywhere and Everywhere
The K3118’s TI based Class-D design makes it an extremely efficient amplifier, and with upwards of 90% power efficiency the K3118 will sound larger than expected while generating less heat, and if operated by a battery will last longer, making it perfect for portability. Capable of operating between 4.5 – 24 Volts DC makes the K3118 ideal for most any application. Best of all, a 12 Volt DC 3 Amp power supply is included.
Performance-Based Features Combined with the Ultimate Support and Affordability
An Original USA Design
With so many "no name" and questionable amplifiers in the market today, you can rest assured that the K3118 has the pedigree for solid audio performance.
Led by USA Texas Instrument Engineering and quality Kinter Manufacturing, the K3118 is the combined effort of two teams working to bring you the best choice as the most affordable, efficient and quality audio amplifier for your listening needs.
Quality Gold-Plated RCA Left and Right connectors and a 3.5mm audio input provide simple connectivity to TVs, Gaming Devices, Smart Phones and more.
Improved spring-terminal speaker connectors accept 14-16 gauge speaker wire, simple press and insert bare wire into the slot.
When you have questions it shouldn't require extra effort for you to get a clear explanation and accurate answer. In addition to Spanish Speaking and other international support staff, we maintain Native English Speakers that can offer technical assistance via email or are happy to call you with the answer to your question or application issue.
Most amplifiers don't come with a power supply, and if they do, the power supply is an afterthought, lacking the power and current ratings to fully enjoy the capabilities of the amp. KINTER includes a 12 Volt 3 Amp power supply (2.1 x 5.5 plug) that provides ample power to drive the K3118 without clipping.
All the Features You Need!
Overview and Specifications
Getting started is easy with the K3118 Amp. First, plug in the included 12 Volt 3 Amp power supply, connect 14-16 Gauge speaker wire between your speakers and the spring loaded terminals on the back panel, connect a source device using either the 3.5 mm MP3 input or stereo RCA jacks, turn the power switch to ON and the tiny Kinter 3118 Amplifier is ready to go. Using the separate Bass and Treble controls you can customize your sound, or push the "Direct" button to bypass the Treble and Bass to listen to source audio without any modification. A large front knob controls the volume and is surrounded by blue LED lighting. Mounting tabs found on the sides of the K3118 amp make it great for DIY projects or other applications where having a fixed location is required.

First I tested it on some speakers at the house. It distorted fairly quickly. But at reasonable volumes that some people would use it worked what seemed to be fine. However, I built a 20W load box with 8Ω resistors and took it to work where I have access to significant electronics including a $40K scope at my desk. I also have a recording studio interface hooked up to spectrum analyzer software.
The first thing I noted on the scope was a LOT of 60Hz ripple coming from the wall wart. I am fairly sure it won't power the unit at full volume anyway. I hooked it up to a lab grade power supply which got rid of that problem.
Next I saw a lot of high frequency noise on each channel. I plugged in a Tek arbitrary waveform generator to put in a sweep from 10Hz to 20KHz. I suspected it wouldn't be flat without using the switch to disable the tone controls. It wasn't flat anyway, especially on the low end with a slight boost. Not bad, just not flat. Listeners would not be disturbed by it.
From memory it had about 30dB of crosstalk between channels in the high frequency region. I considered this unacceptable. Also one channel was around 10dB lower than the other. Again, unacceptable.
I can't say as I would recommend this amp as it won't meet rated specs in any fashion. Distortion was an outlier too as it had distortion that went up and down depending on volume settings. At very low volumes you expect hi distortion and at maximum distortion (especially using the wall transformer). This had spots of 0.5% distortion at mid low and mid high. While hi distortion could be found at the lowest setting, highest settings and in the middle. Strange.
Having said all that if you are REALLY not interested in hi fidelity and just want some noise this may work for you. It is small, inexpensive and I think it looks nice.
My next move is to disassemble it and find out why it performs so poorly because the IC inside (per their manual) is a respectable performer for low wattage. I suspect I can make it work significantly better.
Excellent value for the price.
Doesn't come with mounting screws, appears to have an authentic TDA3118. For the price you can't really do much better.
