Hot 2 Watt Audio Amplifier

This amplifier was designed to be self-contained in a small loudspeaker box. It can be feed by Walkman, Mini-Disc, iPod and CD players, computers and similar devices fitted with line or headphone output. Of course, in most cases you will have to make two boxes to obtain stereo.Circuit Diagram:Parts:P1 = 10KR1 = 33KR2 = 33KR3 = 33RR4 = 15KR5 = 1KR6 = 1KR7 = 680RR8 = 120R-1/

Sensitive Audio Power Meter

As a follow-up to the simple audio power meter described in [1], the author has developed a more sensitive version. In practice, you rarely use more than 1 watt of audio power in a normal living-room environment. The only time most people use more is at a party when they want to show how loud their stereo system is, in which case peaks of more than 10 W are not uncommon.

7 Watt Audio Power Amplifier Circuit Schematic

This
small amplifier is constructed around the TDA2003 IC, capable of
delivering 4Wrms at 4ohms. The TDA 2003 has improved performance with
the same pin configuration as the TDA 2002. The additional features of
TDA 2002, very low number of external components, ease of assembly,
space and cost saving, are maintained. The device provides a high output
current capability (up to 3.5A) very

Telephone line Based Audio Muting and Light On

Very often when enjoying music or watching TV at high audio level, we may not be able to hear a telephone ring and thus miss an important incoming phone call. To overcome this situation, the circuit presented here can be used. The circuit would automatically light a bulb on arrival of a telephone ring and simultaneously mute the music system/TV audio for the duration the telephone handset is
