Audio connectors and Accessories
Not much to put here at the moment, I hope to add info on MP3 players soon.
Phono Audio connector
As seen on the back of all Amiga's. Use a standard RCA connector lead to link the audio of your Amiga to a set of speakers or Hi-Fi. The output is at line level
Line Level Audio?
This uses an audio that is no larger than 1 Volt peak to peak and there is a typical impedance of 1 K Ohm. See above comments on connections.
The audio seems very 'sharp' on the left and right channels, can I do something about this?
Yes you can.
You can buy a mixer which will allow you to blend the two audio channels or you can try one of the circuits listed below, which are available from Aminet.
I have design an Audio mixer suitable fro this task, available here

This is a simple (but comprehensive) HTML guide on making a CDDA mixer, including
a list of components you will need and their approximate prices.
Short: Active Stereo Mixer
This is a high quality, simple to construct, audio mixer.
Amiga audio and CD audio can be heard from the same output.
I built this simple circuit using the low-noise Hi-Fi LF353 OP-Amp.
Passive mixers are simpler but the audio loses some of it's original volume.
This mixer gives the 2 combined signals a small boost to prevent this from

This little schematic shows how I connected 2 cdrom drives (1 cdrom and 1 cd-r drive actually) and the Amiga soundoutput to one output.
The cdrom-audiocables have both been fitted with standard 3.5mm stereo jack.This is done because my mixer is fitted in a box.
Short: Audio Stereo 2 Channels Mixer for the Amiga & CDRom (SPANISH)
This archive contains an audio mixer scheme to mix the audio signals from the amiga and the CDRom audio output port.
The languaje of the GUIDE is SPANISH.
It works with any audio preamplified signal (not phono signals).
You can mix the Amiga audio output with your CDRom audio, Radio,
CDPlayer, Tape... etc.

Short: CDDA Audio Input for Amiga 3000
How many time have you wished that you could have cd-audio inputs on your A3k without having to take up an extra input on your stereo. Well put your mind at ease, cause in approx 20 minutes this could be you. The mod itself is straight-forward and easy to accomplish, the most time consuming part would be stripping the machine down to access the motherboard underneath the the expansion card side.
Short: Do it yourself audio digitizer plans.
Schematic redrawn by Mike Kopack. Parts cost less than $20 for a good
quality mono digitizer, based on the ADC0804 A/D convertor chip.
