HDMI ENHANCED AUDIO RETURN CHANNEL (eARC)
Enhanced Audio Return Channel (eARC) is an advancement over the previous Audio Return Channel (ARC). eARC simplifies connectivity and provides greater ease of use for multiple components discovery and audio optimization.
eARC enables the audio to a TV that originates from cable, satellite, streaming or source devices to be sent to C 399 through a single HDMI cable. This ensures the simplicity of connectivity and that the original audio can be experienced. HDMI eARC works with HDMI High Speed Cables with Ethernet and the new Ultra High Speed HDMI Cable.
eARC is the default mode for C 399 and will fallback to ARC if no eARC connection happens.

• Ensure that the audio setting/format of eARC/ARC-connected devices to C 399 is set to PCM only.
• Only audio output signal from a connected TV is supported by C 399's HDMI eARC port.

On: Display is turned off temporarily after 30 seconds of non- user interface. The Power Indicator LED is also turned off at the same time. Display and Power Indicator LED are activated once user interface is initiated.
Off: Display remains illuminated.

SPEAKER

Select "On" to enable speakers or "Off" to disable speakers.

VOLUME DISPLAY MODE

Volume Display Mode gives the user two options on how to display Volume level. Use or to select between "Decibel" and "Percent" Volume display mode.

SOURCE SETUP

Source Setup has the following menu items:

• Enable Source
• Name
• Volume Control
• Auto Sense
• Analog Bypass
• Analog Gain

At Source Setup menu, select the particular Source you want to configure.

ENABLE SOURCE

One can enable/disable a Source via this option. This is particularly useful if only few Sources are used thereby bypassing unused sources.
On: Enable selected Source.
Off: Disable selected Source.

NAME

A new Name maybe assigned to a Source label. For example, if your BD player is attached to "Optical 1", it is possible to rename "Optical 1"to "BD Player". In order to rename the Source label, select "Name" parameter.

1. While at the selected Source, for example "Optical 1", press ENTER to select "EDIT".
2. Use [] to pick through the alphanumeric selections.
3. Press [] to move to the next character and at the same time save the changes done on the current character. The name can be as long as fourteen characters.
4. Repeat steps 1 and 2 for each character in sequence.
5. Complete the renaming process by pressing [ENTER button again to save the new source's input name. The new Name will be shown in the display.

VOLUME CONTROL

Volume control can be set to either Variable or Fixed level.
Variable: Volume level is adjusted using the volume knob or SR 9's [VOL ] buttons.
Fixed: Output level is fixed and the C 399's Volume Control is bypassed. This feature is sometimes referred to as "Cinema Bypass" because it allows the C 399 to be used for the front channels of a surround sound system by relegating the volume control function to the surround processor.

At Fixed volume level setting, front panel display will show "xx.x dB Fixed" as the volume control is adjusted.

HOW TO NAVIGATE VOLUME CONTROL LEVEL SETTING

1. While at "Volume Control" menu, press [].
2. Use front panel [] or SR 9's [] buttons to toggle between "Variable" and "Fixed" level options.
   1. While at "Variable" option, use front panel [] or SR 9's [] button to select "Variable" level and return to "Source Setup" menu selections.
      
   2. While at "Fixed" option, use front panel [] or SR 9's [] button to select "Fixed" level and return to "Source Setup" menu selections.
      
      1. With "Fixed" level selected and back to "Source Setup" menu selections, use front panel [] or SR 9's [] buttons to go "Fixed Volume" option. "Fixed Volume" manifests among "Source Setup" options only if "Fixed" is the selected "Volume Control" level.
         
      2. Use [] button to go to Fixed Volume level setting.
         
      3. Use front panel [] or SR 9's [] buttons to set preferred dB level setting. Then, use front panel [] or SR 9's [] button to save dB level selection and exit Fixed Volume setup mode.
         

AUTO SENSE

Auto Sense can be setup for each Source. Auto Sense feature enables the designated Source to wake up from standby mode when an active source is detected from the particular Source's input.
On: Unit wakes up to the designated Source from standby mode when an active source is detected from the particular Source's input.
Off: Unit does not wake up to the designated Source from standby mode even if it is triggered by an active source.

NOTES

• Auto Sense is not applicable for Phono and BluOS (if installed) sources.
• Auto Standby must be set to ON for Auto Sense to work.

ANALOG BYPASS

All analog signals remain in the analog domain without analog-to-digital conversions.
On: DSP circuitry is bypassed but full tone control functions remain.
Off: Analog bypass feature is turned off.
NOTE
Analog Bypass is applicable only for Phono, Line 1 and Line 2 sources.

ANALOG GAIN

• Use front panel [] or SR 9's [] buttons to set preferred Analog Gain level.

SYSTEM INFO

"System Info" displays information about current MCU, LCD and FPGA firmware versions.
Use [] to toggle through the corresponding information.
If the optional MDC2 BluOS D is installed, the BluOS firmware version, IP Address, MAC Address (Ethernet) and MAC Address (Wi-Fi) information are also shown.

UPGRADE AVAILABLE

With the optional MDC2 BluOS D installed and C 399 connected to internet, "Upgrade Available" will be shown if a software upgrade is available. If "Upgrade Available" is shown, use [] to go to BluOS upgrade menu. Press [ENTER] to initiate upgrade mode. Internet software upgrade will proceed automatically.
