Hey all! I am working on a project that would benefit from knowing what to expect from an audio input. As such, we are planning on using the typical aucio "line in". I was under the impression that this would be a voltage between 1 and 1.3volts peak to peak... Howver, I have heard conflicting information now, and I need to know once and for all: Is there a standard voltage range that manufacturers of audio equipment (both car and home) stay within for the "line" so that their equipment can feed other devices such as amplifiers? Thanks! Dave
