SUB wiring
When the UT26 processor is equipped with the SUB option (section
), a sub-bass output is delivered on the BCL
port of the UT26 processor. Table
describes the wiring used.

Test before powering up
Before powering up an installation, it is good practice to ensure that the column cable is properly connected to the
column. Therefore, the electrical resistance of each channel of the column must be controlled at the end of the
cable connected to the amplifier side. The measured electrical resistances values must correspond to the values
below.
