Recommendations
When connecting Screen systems 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, 8 and 16 ohm loads.
