Backstop PFL
The System 5-B faders have a backstop switch past the bottom of their travel. Press
Solo Ctrl on the Center Section to open the Solo Control Panel and select Backstop
PFL to enable this feature. Then pull and hold a fader into the backstop to route the sig-
nal’s PFL level to the Solo bus. Release the fader to cancel that fader’s routing to the Solo
bus. Backstop PFL does not affect normal solo operations and can be used on group
masters to PFL a Control Group. Deactivating Backstop PFL cancels the mode
8.2.5 Wave Key
The Wave key has three functions:
• Press the Wave key to bring the Strip (both Swap and Main channels) to the
center Strip (see Chapter 6: CM402 Center Section).
• Press the Wave key when selecting Strips and channels for Layouts, Strip
Expand, Strip Lock, or other operations.
• Like a shift key, the Wave key modifies other keys.
See 8.2.8 for example.
8.2.6 All Mode
When All mode is active on a Strip, that Strip’s function and Swap keys operate on all
Strips currently mapped to the console. This mode is for changing the display only. For
example, when setting EQ on a Strip, the other displayed EQ filters on other Strips are
not changed.
To activate All mode:
1. Hold down the Wave key and press the Clear key at the top of the Strip (above
the top knob’s display).
All appears above Clear.
2. Press any function key (i.e., EQ, Dyn, etc.) on that Strip and all knobsets on the
console display that function.
3. Press Swap to toggle all Strips between their Main and Swap levels.
4. Hold down the Wave key and press the Clear key again to disable All mode.
The All key on the CM401 now sets all strips to All Mode (see page 83).
