01 March 2019 Question by: Graeme | Product code: 70-0188
Q. Hi, Would this work okay with a mono speaker attached? Or would anything need to be considered if I was to do this?
A. Hi Graeme, thank you for your question. This could be used with a mono speaker.

04 July 2016 Question by: Spencer | Product code: 70-0188
Q. If I wanted to change the volume via a potentiometer, where would be the best place to install it? Thanks
A. Hi Spencer, thank you for your question. A volume control is normally at the pre amp stage and this is a power amp only, the volume is controlled by the device connected to it. If you need to add one then circa a 47K lin before R2 and R3.

21 June 2016 Question by: Matt | Product code: 70-0188
Q. Hi, would I be able to easily adapt this kit so that there could be three speakers attached instead of two. And would this effect things like the voltage etc.??? Thanks
A. Hi Matt, thank you for your question. This is a stereo kit designed for two speakers adding a third could damage the output stage and this is not recommended.

18 November 2015 Question by: Debbie | Product code: 70-0188
Q. Can you recommend a suitable heatsink for the TDA2009A chip?
A. Hi Debbie, thank you for your question. 50-5297 looks to be the closest option.

28 June 2014 Question by: kieran | Product code: 70-0188
Q. Can you connect two kits together?
A. Hi Kieran, thanks for your question. Unfortunately you cannot connect the two kits together.

29 April 2014 Question by: victor | Product code: 70-0188
Q. Can you power this via a USB-power supply (5V) ?
A. Hi Victor. Thank you for your question. As USB 2.0 can only deliver around 500mA it will not be ideally suited to power this kit as it may damage the USB device it is plugged into.

10 April 2014 Question by: Tim | Product code: 70-0188
Q. Do you have a recommended enclosure for this unit?
A. Hi Tim. Thank you for your question. There are many different types suitable for the kit, although we do not have recommended enclosure 30-6270 would house the PCB and allow enough room for the external connections excluding your chosen speakers.

28 August 2013 Question by: Gareth | Product code: 70-0188
Q. What is the lowest impedance speaker that this kit can drive?
A. Hi Gareth. Thank you for your question. The minimum speaker impedance would be 4 ohms per channel.
