Note
The maximum output current of the FS-7000AT's ATT Control Output is 0.75 A per circuit. If the current
exceeds this limit, the FS-7000AT's built-in protection circuit cuts off the output. When a control current larger
than 0.75 A is needed, divide both the ATT Control Output lines and the FS-7000JP's speaker lines into 2 or
more lines.
