Set Inputs 1–4 of the
"address 4–7" panels for
the same level.
Set Inputs 1–4 of the
"address 0–3" panels for
the same level.
If, as shown in the figure above, the input level of the "Address 0" panel has a different setting from that of the
"Address 1" panel when their audio outputs are increased,
(1) Setting the "address 1" panel for an adequate volume level will result in a significantly larger input to the
"address 0" panel.
(2) Setting the "address 0" panel for an adequate volume level will result in a significantly smaller input to the
"address 1" panel.
• Twelve outputs
• Sixteen outputs
