The Scene Memory function

Using mute groups

1.In a scene memory number 1–8, store the mute (off) settings of the channels that you wish to use as a mute group.

2.Press the UTILITY switch to move to Utility mode, select the oP (recall operation) item, and

set its value to .” (For details on procedure in Utility mode, refer to page 34.)

Now scene memory numbers 1–8 can be used as mute groups, and the DIRECT RECALL 1–8 switches will function as mute group switches.

3.Press and hold the UTILITY switch for one sec- ond or more, or repeatedly press the UTILITY switch to return to Normal mode

4.To turn on a mute group 1–8 (the mute settings of scene memory numbers 1–8), press the cor- responding DIRECT RECALL 1–8 switch.

Mute groups 1–8 that are turned on will be shown by the indicator of the corresponding DIRECT RECALL 1–8 switch.

5.As desired, press other DIRECT RECALL switches to add mute groups.

6.To defeat a mute group that is on, press the cor- responding DIRECT RECALL switch once again.

The indicator of the DIRECT RECALL switch will go dark, and the mute group will be cancelled.

Note:

•Even while using mute groups, you can use the ▲/▼ (or 0–9/ENTER) and RECALL switches to recall scene memory numbers 9–128. How- ever, the mute settings of mute groups turned on by the DIRECT RECALL switches will not be cancelled.

•If you use the 0–9/ENTER and RECALL switches to recall scene memory numbers 129 (all on) or 130 (all off), the mute settings of the mute groups selected by the DIRECT RECALL switches will be cancelled.

About the local control cir- cuit

In the unlikely event that the system of the M2500 experiences a malfunction so that the scene memory circuit cannot be used, it will automatically switch to the local control circuit. When the local control cir- cuit is operating, the MEMORY display will go dark, and it will not be possible to operate the scene mem- ory switches. However, the ON/EDIT switches of the input channels and output channels will function as conventional on/off switches, so that you can con- tinue to use the M2500 as a conventional analog mixer.

Note: If the cause for the malfunction is in the power supply, it may not be possible to use the local control circuit either.
