Enter the world of amazing electronic sounds and noises. Create or imitate sirens of all kinds by adjusting 3 trimmers. Powerful sound with a 2W amplifier on the PCB.

The WHadda WSAH4003 is a small amplifier, constructed with the TDA2616 IC, with a maximum supply capability of 2 x 15Wrms (4 ohm) of 2 x 10Wrms (8 ohm). The IC is protected against overheating and short circuits. Additional rectifier and smoothing filter are unnecessary because alternating current can be connected directly with the unit.

An electric guitar cannot be connected to just any amplifier or audio installation. This pre-amplifier has been designed for this purpose and provides you with a headphone output, allowing you to practice without disturbing others. Moreover, it is fitted with a special device for tone adjustment so you can create your own sound.

When using one of our amplifiers (big or small), you always need a volume control and preferably also a tone control. The Whadda WSAH8084 electronic kit comes complete with all input / output connections and potentiometers. Furthermore it is possible to amplify or attenuate the input signal.

Finally it is possible to build your own MP3 player! Create you own home audio system, jukebox, jingle player, audio messages or sound effects.

A small compact spectrum analyser, suitable for panel mounting or fitting in to existing equipment.

This kit was developed as module for a number of audio applications where the input signal is too weak. Applications such as a microphone pre-amplifier or for signal level correction.

The Whadda WSAH4001 is a small amplifier,constructed around the TDA2003 IC, capable of delivering 4Wrms at 4 ohms. The IC is fully protected against overheating and short circuits. A conventional direct current is sufficient as power supply.

A good pink noise generator and a spectrum analyser are indispensable if you want to analyse the acoustic properties of a room (usually a living room). Moreover, you also need a microphone with a frequency characteristic that is as linear as possible (from 20Hz to 20kHz). If you have an equaliser, then the response can not only be checked but also corrected. The kit is easily adapted to produce "white noise"

VU meter with a scale consisting of 10 LED's and an adjustable input. Dot or bar indicator. Supplied with 1 front panel suitable for horizontal or vertical mounting.
