AVT EDU644 LED Colorophone Instruction Manual
It has not been known for a long time that the alarm alerts, the painter
paints and the resistor puts up resistance. So, if one day someone were to ask
you what the Colorophon actually does, the answer is childishly simple – the
Colorophon colours 🙂
However, we know that not everyone has as sophisticated a sense of humour as
we do, so we also include the product description below if necessary
The colorophone catches the surrounding sounds and, depending on their tone,
frequency and intensity, lights up in a quite different way for each sound.
The application of this smart device is much more interesting than it might
seem.
It is not only useful for partygoers, musicians and audiophiles – there are
many more options. From rave parties (or indeed all parties), to signalling to
children that they are too loud, even to checking who is snoring in what key.
Referring to the above description, virtually countless other possibilities
for the use of our Colorophone come to mind.
Of course, the most essential function of our EDU kit is the opportunity to develop passion and soldering skills.
Specifications
- Integrated micron – no direct connection to sound source required
- Light source – LEDs in three colours
- Stepless sensitivity adjustment Light effect produced to the rhythm of the music responds to low, medium and high tones supply: 12 VDC /200 mA (2.1/5.5)
- Board size: 149 ×79 mm

Mounting and start-up
Figure 2 shows the layout of the components on the PCB.
Fig. 2. Arrangement of components on the PCB
Solder the components sequentially onto the board, starting with the smallest ones. Once the system has been mounted, very carefully check correctness of installation. Check that the components have not been soldered in the wrong direction or in the wrong places and that no soldering points have been shortcircuited during soldering. The sensitivity of the Colorophone can be adjusted using potentiometer PR1.

Start assembly by soldering components into the board, in the order of their size, fromthe smallest to the largest. When mounting components marked with an exclamation mark, pay attention to their polarity.
Components received in the kit, may differ in appearance from those shown
in the photograph. Despite this, they have the same parameters, and their
appearance will not affect their operation in the unit.
Mounting instructions
- Use the tip of a hot soldering iron to touch the leg/end of the component just outside the soldering field.
- Then apply the “tin”/spoil
- Once the cone has formed, remove the ‘tin’ and then the soldering iron.
- The entire process should take 2-3 seconds The prerequisites for the formation of a correct solder are the cleanliness of the surfaces to be joined, the presence of flux in the binder, a sufficiently high temperature (320-360°C) and the correct amount of binder.
Too much binder will cause a bead to form or two adjacent solder points to
join.
Too low a temperature or amount of binder, as well as impurities, can lead to
“cold solders”, i.e. the binder and the flux contained in it do not wet the
surfaces to be joined and an impermanent solder is formed, which will oxidise
over time, a break will occur and the device will cease to function.
