Need a sketch or diagram showing someone sitting at a desk with a speaker either side of a monitor on stands with a line drawn showing the the ear level of the listener to a position on the speaker.
Also need a diagram showing wires being connected to the back of a speaker and being connected to the back of an amp (can use existing speaker back you have done)
Red (+) and black (-) is important in the speaker digram and should be illustrated. The right connector on the speaker is Red (+). There should be a left and right speaker connected to Lout and Rout respectively.
Have attached some stuff that shows what is required for the two illustrations.
Red line shows where ear level needs to be on the speakers and the digram to the left is just an example of the kind of thing we're after (not the particular style though - the style can be anything you like, whatever is quick for you and gets the message across).
We don't need this to be vector or in any particular style - it will be used in a user manual.
