2. Installation (contd.)
2.4. External connections
The input and output connectors are wired on female and male XLRs respectively, wired as follows:
Pin 1: Ground
Pin 2: Hot balanced signal
Pin 3: Cold balanced signal
2.5. Impedance & Termination
Most modern audio systems have cable runs of less than 100 meters; the devices used usually have very low output impedance and relatively high input impedance. This allows equipment to be connected in series without regard to "impedance matching" (as long as the succeeding input is greater than the stated minimum for the output it is connected to).
LA Audio products conform to this standard; therefore inputs and outputs are usually indifferent to varying load or source impedance. The only exception to this rule is where the unit is connected to a transmission line or some older
