C1.2 User Manual

5.1.4 DISPLAY
Display mode: The C1.2 screen can display a status page, a volume bar, or be turned off.
Front LED: Allows users to select whether the front panel LED is on or off when the C1.2 is operating.
Brightnesss normal: Allows you to set the brightness of the display in operating mode (10 – 100%), and to fine
tune the high brightness gamma curves to perfectly match the brightness and color of other displays.
Brightness dimmed: Allows you to set the brightness of the display when dimmed between operations
(10 – 30%), and to fine tune the low brightness gamma curves to perfectly match the brightness and color
or other displays.
Colors: A different display color can be allocated for each different type of audio stream type (PCM, DSD,
MQA, MQA Studio and Analog input).
5.1.5 SHORTCUTS
The C1.2 allows you to establish up to six shortcuts, taking you directly to almost any parameter in any menu.
The C1.2 is preprogrammed with Mute and Phase Polarity as shortcuts one and two. After scrolling through
the last shortcut, the next screen that the C1.2 displays is the entry port to the C1.2 menu. It reads Detailed
Setup.
5.1.6 NETWORK
Status: Shows a list of compatible devices detected on the LAN.
Role: When physically connected to a network, the C1.2 can ignore this network (offline) or connect to it as
either the Master unit (it will transmit push-button commands to all compatible client units) or as a Client
(it will ignore push-button entries and receive commands only from the master device). This networking
facility allows system-wide sharing of commands among CH products (such as mute or power up/down)
Room number: Defines the room in which the C1.2 is located for multi-room applications. This prevents
CH Precision units connected to the same network but located in different systems/rooms to interact with
each other.
IP settings: Auto should be selected if the C1.2 is connected to a router with DHCP server feature. Direct-Link
should be selected when an RJ45 Mirror lead directly connects a C1.2 to a single other CH Precision device.
More advanced settings are available if needed.
Wake-on-LAN: If ‘No’ is selected, the C1.2 cannot be switched on from the CH-Control App. If ‘Only If POE’ is
selected, connecting the C1.2 to a Power Over Ethernet switch will allow it to be switched on via the CH-
Control App (Standby consumption will be less than 0.5W). If ‘Yes’ is selected, the C1.2 can always be switched
on by the CH-Control App (Standby consumption will be less than 2W).
Power off command: If Yes is selected, the C1.2 will enter standby mode when it receives a Power Off
command from the LAN. It will remain on if No is selected. This is useful if you want to keep your C1.2 on even
when you turn off the rest of your system.
