Our new 3W class D stereo amplifier offers great sound quality at a power level in between our Deluxe Stereo Amplifier Kit and our High Power Amplifier Kit.

The amplification is done by a PAM8008 3W amplifier IC, which offers excellent amplification when powered with anything from 5.5V all the way down to 3.2V, making it ideal for portable battery powered applications which require high quality stereo output.

The kit is supplied with a 3.5mm jack lead and 2 high quality, full range speakers, which are 5W and 65mm in size with corner mountings. The kit features a volume control & power LED as well as an on/off switch that switches between battery power, off and micro USB power.

Runs off 3x AA batteries or a micro USB power supply (used to charge many phones, tablets and e-readers).

Features:

  • Easily portable battery powered amplifier kit.
  • 3.5mm jack lead compatible with all standard audio equipment.
  • Full range speakers.

Question:

Would this speaker circuit be able to be powered by your Polymer Lithium Ion Battery (3.7V, 1Ah)?

Answers:

    Hi Robert, You could use this to power the kit, however it is only likely to last maybe a couple of hours so before the voltage drops below the minimum of 3.2V’s.

Question:

I have never made anything electrical before and wanted to know if this set comes ready made? i.e the circuit board etc and just have to solder the other bits like in the other kits.

Question:

Hi - I would want the students to have the opportunity to swap out the green LED (provided) for other colours. Can you possibly list me the product numbers for RED / Blue / Yellow etc (5MM) direct replacement LED's that would not require any alteration to the resistance provided in the Amp kit... essentially straight swap LED's from your product range. Thank you . Do you also sell any alternate switch designs that work in the same way as the one in the kit (I assume they are ..charge from battery / off / charge from USB)... thank you, (just need this info to finalise my order)

Answers:

  • Posted by Michael Lockhart on Thursday, 16 June 2016

    You could swap the LED out for any of the following which are direct replacements and would need the resistor changing, 3504, 3506, 3567, 3543, 3542. The last two codes would only need a resistor value of 150 Ohm, however keeping the 220 Ohm resistor would be fine. With regards to the switch it is possible to swap this for a different one, however you would need to ensure that it has the same pins as the one supplied in the kit, here is a link to the datasheet, https://www.kitronik.co.uk/pdf/3427_datasheet.pdf

Question:

Hi Can the LED / Slide switch / volume control be put on fly leads and placed in different positions ( I assume the USB charger is fixed to the board?).

Answers:

  • Posted by Michael Lockhart on Tuesday, 14 June 2016

    Yes the LED switch and volume control are fine to be put on flying leads. As long as they are connected up in the same way as they would on the board then it will be fine. Unfortunately you are correct the USB charger is pre-mounted onto the board.

Question:

Can I have 3W Class D Stereo Amplifier kit without the speakers ?

Answers:

  • Posted by Michael Lockhart on Monday, 9 May 2016

    Unfortunately we can only supply the kit as it is shown on the website, we are unable to provide a speaker less option.
