12 best mini stereo amplifiers

A mini stereo amplifier is a compact electronic device designed to amplify audio signals from various sources, such as CD players, turntables, smartphones, or computers, and drive speakers to produce sound. These amplifiers are typically smaller and more streamlined compared to their larger counterparts, making them suitable for spaces where space is limited or where a more discreet setup is desired. Here are some key points about mini stereo amplifiers:

  1. Compact Size: Mini stereo amplifiers are intentionally designed to be small and space-efficient. This makes them ideal for small rooms, desktop setups, or situations where a more discreet audio system is preferred.

  2. Amplification Power: Despite their small size, mini amplifiers can still provide significant amplification, often enough to power small to medium-sized speakers. They come with various power ratings measured in watts per channel (WPC), indicating how much power the amplifier can deliver to each speaker.

  3. Input Options: These amplifiers typically offer a range of input options, including RCA, 3.5mm AUX, Bluetooth, and sometimes even digital inputs like USB or optical. This versatility allows them to connect to a wide variety of audio sources.

  4. Output Options: Mini amplifiers can have outputs for multiple speakers, allowing for stereo or even multi-channel setups.Some models may also include a subwoofer output for enhanced bass.

  5. Built-in Features: Depending on the model, mini amplifiers may have built-in features like tone controls (bass and treble adjustments), volume knobs, and sometimes even equalization options to fine-tune the audio output.

  6. Bluetooth Connectivity: Many modern mini amplifiers come with Bluetooth capability, allowing you to wirelessly connect your audio sources. This is particularly useful for streaming music from smartphones, tablets, or computers.

  7. Power Source: Mini amplifiers can be powered by a standard electrical outlet or, in some cases, by rechargeable batteries. Battery-powered models offer portability, making them suitable for outdoor use or in areas where power outlets are limited.

  8. Price Range: The cost of mini stereo amplifiers can vary widely depending on factors such as brand, power output, and additional features. Entry-level models are generally more affordable, while high-end models with advanced features may be more expensive.

  9. Brand and Model Varieties: Many well-known audio equipment manufacturers produce mini stereo amplifiers, including brands like Yamaha, Sony, Denon, and more. Each brand may offer a range of models with different specifications and features.

  10. Application: Mini stereo amplifiers can be used in various settings, including home theaters, desktop audio setups, bookshelf speaker systems, and small room audio solutions.

When choosing a mini stereo amplifier, it's important to consider factors like your intended use, the types of speakers you'll be using, and the compatibility with your audio sources. Reading product reviews and comparing specifications can help you find a model that suits your specific audio needs.

Kinter K3118 2 x 15 watts Digital Audio Amplifier - the perfect choice for nearly every audio listening need.

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.

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!

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.

Specifications: • Power output: 2 x 15 watts RMS • Speaker impedance: 4-8 ohms • SNR: >102 dB • Input impedance: 47k ohms • Frequency response: 20 Hz - 22 kHz • Input sensitivity: 200 mV • Minimum THD: <0.1% • Dimensions: 4.72" D x 5.79" W x 1.65" H.

Power Supply Specifications: • Input: 100~240 VAC, 50-60 Hz • Output: 12 VDC, 3A (minimum) • 2.1 x 5.5 plug.

Please Note: The included power supply is capable of driving this amp at 2 x 15 watts per channel. To realize the full potential of this amp (>20 watts per channel), we recommend a power supply that is capable of producing 60 watts of total output.

User questions & answers

Question: Will this work to power speakers from a presonus interface. from what i see it should work. anyone have any experience with this
Answer: I use mine to amplify the output from either a ECHO Layla PCI audio interface, and a Focusrite 6i6 USB audio interface, and it works great. So long as the presonus is putting out "standard" Line levels you should be golden
Question: Where is it made
Answer: China
Question: can this be used for 2 subwoofers
Answer: Yes, it could be used for two individual passive subwoofers, but you'd need two subwoofer (low frequency only) outputs from your receiver/preamp/mixer.
Question: What type and size of audio output jacks? Banana plugs
Answer: Audio input is RCA phono plugs. Looks like speaker jacks will take banana plugs, but I just used bare wire. The jacks have holes through them to accept wires.
Question: Is the 2013 new version a worthy upgrade over the older LP-2020A+ model? The newer one has slightly worse reviews comparing 5 star to 1 star reviews
Answer: Yes, the newer version doesn't have the "pop" during startup and shutdown. I own several versions dating back to 2008 (ie: the original hardwired version).
Question: There seem to be two inputs on the back - one RCA and one 3.5mm - how do you get the receiver to switch between them
Answer: The receiver defaults to using the 3.5mm input. If there's something playing on that input, that's what the receiver will play. If there's nothing playing on the 3.5mm input then the receiver will use the RCA input.
Question: What makes this product "upgraded" from the previous version? http://www.amazon.com/gp/product/B0049P6OTI/ref=olp_product_details?ie=UTF8&me=&seller
Answer: It's not really an upgrade. The Tripath chip in the LP2020A+ was a very different type of amplifier than the TI TPA3118 in this one. These are good in a different way, but not the same thing. I used an LP2020A+ to drive a pair of 12" Yamaha stage monitors, loud enough that you couldn't hear yourself thing. The TI version probably has higher fidelity, but it doesn't have the same kind of drive capability. The Tripath chip from the 2020A+ is extinct. There are no more, and no more will be made.
Question: Why is Amazon permitting the the folks from iFinity to leave such an obvious trail of negative recent reviews for this product
Answer: Are you saying that these recent negative reviews are false? I was beginning to get nervous; my amp is scheduled to arrive tomorrow.Btw, I just discovered that many of the negative review comes from those who have not been verified as owners. Those who are verified by Amazon as actual buyers seem to give good reviews.
