CH L1 - Shortcuts

Displayed elements depend on the user settings. In the example above, an X1-powered (X1 PSU symbol) L1 is set as a dual-
monaural preamplifier (LEFT + RIGHT), input XLR 1 is selected without coupling capacitor (DIRECT COUPLING) nor resistor
termination (High-Z). The audio content of both preamplifying boards (left and right) is inverted (H), summed up (MONO) and fed
with an attenuation of 18.5 dB to each output (left and right). The output is actually muted (7) so no signal will come out of the
L1's outputs.
Following table shows the actions of the user control knob in Normal mode.

4.2.2 Shortcuts
The L1 preamplifier settings are accessible through a set of menus as described in the next sections. However, to allow quick access
to the most frequently used configuration menu items, the L1 offers the concept of Shortcuts. Shortcuts are fully programmable
and the user may choose almost any configuration parameter as a Shortcut. There are up to 6 user programmable Shortcuts. To
learn how to program individual Shortcuts, please refer to the SHORTCUTS menu item in the next section. For a list of Factory
default Shortcuts, please refer to the Specifications section.
Shortcuts are accessed from Normal mode by a Normal Push [NP]. Additional Normal Push [NP] skips to the next Shortcut. The last
Shortcut is always dedicated to entering the Menu mode (SETUP). On this last Shortcut, a Normal Push [NP] will return to Normal
Mode and an External Rotate Right [E>>] (or Central Rotate Right [C>>]) will enter the Menu mode. The individual parameter for
a given Shortcut is modified using External Rotate Left [<<E] (or Central Rotate Left [<<C]) and/or External Rotate Right [E>>]
(or Central Rotate Right [C>>]) . If there is no user action for about 10s the unit will revert to Normal mode.
Following table shows the actions of the user control knob for Shortcuts.
