10.4.3 Field Wiring

The following table details audio load, wire size and length of cable runs.
Calculations are based on a 1 dB of loss (approx. 10V attenuation at the end of the cable run)
Amp Size Load
Impedance
40Watt 250Ω
120Watt 83.3Ω
240Watt 41.7Ω
Max capacitance must be below 100nF and max inductance must be below 1mH
