7. Frequently Asked Questions

Can I use this amplifier with headphones?

While the Kinter MA170+ is primarily designed for use with speakers, it can be used with headphones if you use a separate, independent pair of wires for each channel (left and right). Please note that the left and right ground (negative speaker terminals) do not share a common tie point, and the same applies to the positive terminals.

Can I disable the LED lights?

The LED lights cannot be turned off separately from the amplifier. If the lights are bothersome, you can access the internal components and disconnect the LED light connection. However, this may void the warranty and should be done at your own risk.

What type of speakers can I use with this amplifier?

The Kinter MA170+ is compatible with a wide range of speakers, including bookshelf speakers, outdoor speakers, and small home theater speakers. Ensure that the speakers you choose are compatible with the amplifier's 2 x 18W output power.

Can I connect this amplifier to a TV?

Yes, you can connect the Kinter MA170+ to a TV using an appropriate audio cable (e.g., a 3.5mm to RCA adapter). Please note that the TV's volume control will act as a master control, and you may need to adjust the TV's volume in addition to the amplifier's volume control to achieve the desired sound level.

FAQ:
Q: Can you somehow connect a Bluetooth speaker to this amplifier or to any other hifi amplifier for that matter?
A: No, the amplifier only has RCA plugs for L & R inputs and four output Speaker terminals for L (+-) and R (+/-). The amplifier does not support Bluetooth operations.

Q: Does this amp have enough power to run four 4" speakers?
A: Yes, as long as you wire the four speakers into two pairs with no less than a 4 ohm impedance per pair. This amp is not rated for use with a 2 ohm speaker load, which may cause damage to the amplifier.

Q: Can I connect to a Vizio TV and use it to power speakers?
A: Yes, you could hook up the amp to a TV and use external speakers. However, this unit is very weak with output. You would be better off with a cheap sound bar made specifically for a TV.

Q: How does this hook up to Arcade1up? This has RCA audio inputs but need an RCA to 3.5mm cable? How would this attach to the speaker? Sodder?
A: This amplifier will hook up to any RCA L and right outputs.

Q: Can I use this as a pre-amp for a record turntable and plug outputs into two Bluetooth speakers?
A: Yes, you can use this amplifier as a pre-amp for a record turntable. However, the amplifier does not support Bluetooth operations.

Q: What class D chip amp is used on this unit?
A: The specific chip amp used in this unit is not specified by the manufacturer.

Q: I'm getting white noise only when I connect the two input channels. If I only use one, the audio comes out ok from the speakers. Anyone know why?
A: If you troubleshoot both inputs by moving the working channel from L to R and vice 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. If you find the problem still does not go away, then you have a bad unit and you need to exchange it.

Q: Where is my power supply!?!?!
A: If your package did not come with a power supply, please contact Amazon customer support for assistance.

Q: Can you split the wire between left and right PC speakers and hook it to terminal on this amp?
A: Yes, you can split the wire between left and right PC speakers and hook it to the terminal on this amp. However, since there is amplification from the PC, the amp range of the device might be limited, and there may be some distortion at higher volume.

Q: 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?
A: Yes, this amplifier allows independently customizing the amount of bass and treble from an audio source. However, the sound quality may not be as good as a dedicated receiver or amplifier.
