User questions & answers

Question:	Does this amp have enough power to run four 4" speakers
Answer:	This amplifier allows independently customizing the amount of bass and treble from an audio source. It doesn't sound very good but it has those controls.
Question:	I am looking for more control over bass treble. Hook this into any audio out and keep speakers plugged into receiver and still get functionality
Answer:	Mine didn’t come with a power supply either. I contacted amazon to correct the issue. It was a simple mix up since they sell the exact same amp, with and without the power supply. They sent a whole new amp and power supply.
Question:	Where is my powersupply
Answer:	Do you mean white noise? I am going to assume it was a type. If you troubleshoot both inputs as in moving the working channel from L to R and vise versa and both channels work with one wire, do the same from the source. Make sure it is not the source. Try a different device. I mean this is sort of basic troubleshooting. If you find the problem still does not go away , then you have a bad unit and you need to exchange it.
Question:	I'm getting white mouse only when i connect the two input channels. if i only use one, the audio comes out ok from the speakers.anyone know why
Answer:	Hi, please do not worry, the tracker built-in USB Plug.Just pull it down along vertical rather than horizontal direction to separate the device from the wrist strap, easy to charge with any USB block and computer; no charging cable or dock needed

Quick tips:

1. Please plug the power cord into the amp THEN the wall, plug the audio cables into amp THEN switch on.

Some customers may see some slight sparks flying when they plug the power supply into the amplifier, because they use it in wrong way, you need to connect the amp to the power supply first, then plug the power supply into the 110v AC outlet, don't worry about the sparks, because this is class d amplifier, the capacitors need to charge when the power in, it's normal and safe.

2. The amp will off when you switch off, but it’s normal that the power LED light stay on even switch off, the power LED light on means the power supply in.

3. What will cause noise?

Poor quality audio cables, Sound source, Speakers, Other interfering signals;Incompletely connections.

User questions & answers

Question:	can I connect two BT phones at one time and switch between them to play music? or does it remember last device and won't allow switching unless reset
Answer:	I believe it pairs with only one device at a time.
Question:	Is there a button to press in order to pair BT to cellphone
Answer:	Nope, as long as there is nothing in the AUX input it will be in Bluetooth mode. You need to pair it from your device.
Question:	Can this unit be setup to default to bluetooth input and pair when powered on? (i.e. echo dot as the source via bt
Answer:	Yes it can just do not plug in an auxiliary because it will reset the whole thing basically and then you have to how go through the whole Bluetooth process setup again so just leave it on bluetooth
Question:	Can two of these be hooked up together, I want to make a four speaker bluetooth boombox
Answer:	well it depends on what you mean by "two of these hooked up together". Firstly having two of these amps would need two power inputs and two audio inputs. Powering isn't the issue as you'd have two separate adapters for that. For audio inputs using Bluetooth you can't connect your source (phone or laptop) to two different amps via bluetooth at the same time. But you can use a 3.5 mm Audio jack splitter to connect to both amps. Or if you have to power 4 speakers through one amp you can just connect 2 speakers to each of the right and left channels of the amp. I hope that answers the question

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.

Answer:	Hi, thanks for reaching out to us at Boley! Yes, the animals do stand on their own. Let us know if you have any other questions!
Question:	Would I need a low pass filter for connecting to bass shakers or could I just turn treble all the way down and bass all the way up

User questions & answers

Question:	Can this be used with a tube preamp using a rca/3.5 mm adapter
Answer:	I used 2.5 bags for 6 5 gallon pots.
Question:	Rms rating
Answer:	1 teaspoon is just under 5 ml. 1 tablespoon is just under 15 ml
Question:	Is this enough for sony sscs5 speakers
Answer:	Absolutely. Depending on the stage of growth, you may need to fertilize with lower than the recommended rates, and then ramp up as the plant gets bigger. Guava plants have a very large range of size, so there are no one-size-fits-all application rates. Bloom Fuel will help to grow bigger, juicier, fruits and give the plant what it needs to fill the fruit faster.
Question:	Does this make a sound when turned on or when the bluetooth connection is made
Answer:	Yes, as long as you fertilize at the same time as you would with the actual lotus pond fertilizer, and at low rates.
