Setting up loop isolator speaker lines - Configuration

The following digital matrices support speaker line loops with loop isolators PCA2005 'Loop isolator (100V)':

• PC2003 'Digital audio matrix (4/4/16)'
• PC1001 'Voice alarm panel Compact 400'
• PC1002 'Voice alarm panel Compact 1000'

A single amplifier channel can supply up to two loops, but with the limitation that the two loops are always treated as a single output zone.

It is possible to mix speaker line loops with loop isolators and stubs with impedance supervision on one digital audio matrix.

It is not allowed to mix speaker line loops with loop isolators and stubs with EOL3 supervision on one digital audio matrix
