Audio Power
How do i make a high power audio amplifier?
I am looking to make a 200-???? watt amp to put in my car to power various speakers. Does anyone have plans or know how to make such a device? If so I would be very thankful to know =)
look at the kits available from jaycar or tandy or dick smith .To build your own from scratch requires very good electronics skills. Search everyday electronics and silicon chip magazines as I know they both had quite good circuits for power amps, that a diy could build.

Echo Indigo IO, an audio recording interface
Audio recoding equipment plays a very vital role in recording audios instantaneously and there are numerous kinds of studio recording equipment available. In the world of audio recording, audio recording interfaces makes recording easy and convenient. The different models of audio recording interfaces provide one stereo analogue input of 1/8 inch along with an output on the Type II Cardbus card that is powered via your notebook PC. Many of the interfaces merge with the 24 bit/ 96 kHz converters to offer the quality you desire. Also included is the six-foot audio cable for connections of ¼ inches or RCA.
An exclusive feature of the recording interface is that it makes the use of the virtual outputs. It appears like software, since it incorporates eight individual outputs that are mixed down digitally with physical outputs via using the interface console software along with on board DSP. This further makes interface attuned with all the famous multi track software. In addition, with Echo’s multi client drivers above than one function like software synth and editor can be done at same time through audio interface.
Some audio recording interface hardware features
1 stereo analogue output of 1/8 inch
1 stereo analogue input of 1/8 inch
Supports duplex two channel out, two channel in operation
Superior quality headphone amplifier
Analogue volume balance knob for the output
Supports true 96 kHz, 24 bit audio
Powered by notebook PC
Incorporates six-foot adapter wire for ¼ connections and RCA
Some audio recording interface software features
Software control in order to meter, monitor and setting the levels
In built digital mixer gives almost zero latency monitoring
Supports Macintosh OS X and Windows Me/2000/ XP
Supports the pre-audio software, including ASIO, WDM Kernel Streaming, CoreAudio and GSIF
8 virtual outputs and run multiple applications
Low latency drivers
Analogue output and input
The analogue input and output of many audio interface include 1/8 one stereo connector with frequency response of 10Hz to 20 kHz and 0.5dB and dynamic range of 109dB. The maximum input level of interface is +7.2 dBu, and the nominal input is -10dBV. Where as, the maximum output level is +6.3 dBu with nominal output level of -10dBu.
The audio recording interface constitutes a 128x oversampling converters and 24-bit data resolution that maintained all through signal path. Apart, the multiple sampling rates supported by an audio interface are 32k, 48k, 96k, 88.2k and 44.1k.
