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.
Easy Connections
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.
NO Frustrations!
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.
Power Included
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.

I mainly purchased this mini audio amp to replace the one I currently have because of buzzing noise it was making for the living room TV. It sounds better without that annoying buzz and does the job well. That's why my living room TV sounds better when I hooked it up to the RCA audio output behind the TV.

I recently found some hidden gems at Goodwill - a pair of bookshelf speakers in need of a worthy amplifier. After scouring the market for an affordable option, I stumbled upon these gems. Not only were they the most budget-friendly amplifiers around, but they also boasted the credibility of a name brand op-amp, Texas Instruments!To be honest, I didn't set my expectations too high, but oh boy, was I in for a pleasant surprise! This amplifier exceeded all my assumptions and then some. At this price point, it keeps things simple without unnecessary frills, but let me tell you, when I compared it to my $600 Yamaha Amplifier in "Pure Direct" mode (which essentially means no Yamaha DSP magic), this little powerhouse held its ground remarkably well.The music reproduction is phenomenal, matching the performance of its much pricier counterpart. The clarity, depth, and overall sound quality left me in awe. I can't stress this enough - for the price, this amplifier delivers an astounding performance. If you're on the hunt for an affordable yet impressive amplifier, look no further. This is the real deal, providing exceptional value for your money. Don't miss out on the musical magic this amplifier has to offer! Highly recommended!

What do you get? Mine was fully functional, without unexpected performance issues. Both channels evenly balanced and clear. Used for near field monitoring output volume satisfactory with included power supply. For larger spaces an upgrade would be better. Sound is clear and not harsh or brittle as some cheap class D can be. The housing is metal though thin, knobs are cheap and unattractive. The tone/direct switch functions well but feels cheap and I believe is something that will eventually fail. The tone controls seem well voiced. The direct setting may seem rolled off in the bass. However it is far more detailed with better sound staging in this mode. I would suggest a separate eq be used. With tone control the sound is not bad and may be more pleasing for people. Mine is for mobile music production, I appreciate the clarity of direct. The speaker spring clips are good, and easily accommodated 16awg wire. I can’t speak to the longevity of this amp with the entry level toy-like controls. But the price balances that out.
