Impedances indicated in the figures represent the total speaker system (load) impedances. Be sure to replace the speaker terminal cover after speaker connections have been made. 4.
5. OPERATION OPERATION MUTE FUNCTION You can only choose two of the four output connectors to work together. If voltage is 70V/100V the speakers must have a transformer, make sure the total power wattage of speaker is 15% less than the power wattage of amplifier. 1. TEL has priority over all inputs. 2. MIC 1 is second priority, adjusting the mute level can override all other input signals except for the tel signal. TROUBLESHOOTING Problems Cause 1.
