10 Appendix C: Cabling section for speaker lines.
The table below reflects the maximum desirable distance for 100V speaker lines. The type of
cable that is used for the calculations is a two-wire type with copper conductor. The values
shown may be used as a guide for planning, being the responsibility of the installer who will
make the appropriate final calculations for each case.
The table shows the output power of typical amplification channels, constant voltage 100V in
effective watts (rms) are expressed. The maximum length for 70V lines is half of what is
reflected in the table.
