6. EXtERnAl MUtE SWItCh tERMInAl
It is a terminal to connect the switch when operating the degree that the sound of INPUT 1 – 6, CHIME, EXT
IN are decreasing in this device. When the contact closure comes in External MUTE switch terminal, the
sound of INPUT 1~6, CHIME, SIREN, EXT IN decreases as much as the volume controlled with the TEL IN
priority control volume and priority control volume (PRIORITY MUTE).

It is a terminal to use when connecting the speaker. When connecting the speaker, use not to be in overload state.
You can control SP1 - 5 terminal with the speaker selection switch on the front side.
Be careful not to use 8/4 terminal and SP1 - 5 terminal (high-impedance speaker terminal)
simultaneously.
When connecting the speaker, connect the speaker to use to the speaker terminal on the rear panel in
accordance with the following connection after removing the power cord from the outlet.
Caution: Be careful not to make total impedance of the speaker terminal to be lower than defined impedance
