Cable lengths
When connecting an ICT500 to an amplifier, it is recommended that the return
resistance of the cable used is less than one tenth of the nominal impedance
of the system or systems in parallel. The table below gives an indication of
the maximum permissible cable runs for various conductor cross-sectional
areas driving 4 ohm loads.

To work out the actual return resistance R for cable run of length L, with each
conductor having cross-sectional area A, use the formula:
R = 2 x 0.017 x L
