4 channel amp question & line/preamp question.
As the subject implies, I have two questions.
The first relates to levels. I always thought that line level was really low, like a volt or so and that preamp levels were a bit higher and that a preamp was needed on a line level to drive an amp to speaker levels. After searching the web a bit, I now think that preamp levels are either a little lower than line levels or they are about the same. In fact, I think there is no fixed firm voltage/current values attached to these.
The point is auto amplifiers seem to list preamp inputs so the question is, does that mean it's all right to just connect the line level outputs of my SB live 24 external to the preamp inputs of a regular auto amplifier. I believe it is. In fact, in the next picture the amp which lists preamp inputs actually has them labeled as line level input on the back panel.
The next question is: Am I correct when I say that I should be able to connect say the front outputs on the SB to the left and right line level inputs on Channel A of this 4 channel amplifier and the rear ouptus of the SB to the left and right line level inputs on channel B of the amplifier and I should then have control of both fade and balance on a 4 speaker system using the SB? Again, I think so, but I would appreciate some confirmation and opinions on both subjects.
