Question:

Hi. Can I use this kit as a pre amp for your high power stereo amp kit please

Answers:

  • Posted by Aaron Sturman on Tuesday, 27 May 2014
    Hi, it is possible but you might not need a pre-amp depending on what your signal source is. Can I ask what you are using it for?

Question:

Hi, Can this kit be connected up with an iphone/pod dock (instead of the 3.5mm jack) and different speakers? Thanks

Answers:

  • Posted by Matt Macleod on Friday, 11 April 2014
    We have tried this kit with an iPod and whilst it does work there is no volume control on the iPod or on the amplifier kit so you get the music played at full volume which is inevitable distorted. I suspect that an iPhone will be the same as the iPod, but haven't tried this. It would be possible to use two potentiometers to create a volume (and balance control). The speakers could be changed however the IC on the board will only drive 1W into each speaker so you wouldn't necessarily hear the benefit of using better speakers.

Question:

Hi, I have recieved a leaflet from you with this product on the front, with it is also a picture of the boombox. Is this incorperated in the price or are they brought seperately? Thank You

    The boombox is available separately. There is a link in the related items on the left of this page. You can also see some pictures of how schools have boxed the mono amplifier using other materials by clicking on the camera icon. We often find that if schools are short on time and want to focus on the electronics then they will use the boombox which can easily be personalised. If more time is available then students will be able to make their own enclosure, in this case it is often useful to have some boomboxes to hand as there will often be the odd student that hasn't managed to finish their case and still will get to take away a finished product.

    We do a deluxe version of the stereo amplifier which includes a volume control, power LED, on/ off switch and optional DC jack plug, for product details see: http://www.kitronik.co.uk/products/project-kits/ic-based-kits/deluxe-stereo-audio-amplifier-kit/
