ENGLISH
NETWORK STANDBY
Network Standby mode maintains network connection at standby mode
with reduced system performance level.
On: Network connection is maintained at standby mode.
O: Network connection is disconnected at standby mode.
CEC POWER
CEC Power feature is activated when CEC/LAN/BluOS IN STANDBY is set to
On.
HDMI CONTROL CEC
Consumer Electronics Control (CEC) is a set of commands that utilizes
HDMI’s two- way communication to allow for single remote control of any
CEC-enabled devices connected with HDMI. A CEC command will trigger
the necessary commands over HDMI for an entire system to auto-congure
itself to respond to the command.
O: CEC feature is disabled. C399 will not pass through any CEC
message.
On: Execute the CEC command. For example, C399 will automatically
go to standby mode if it receives a CEC standby command. On the
other hand, if the C399 receives a CEC power up command, the C399
will correspondingly switch ON from standby mode.
AUDIO RETURN CHANNEL ARC
ARC enables an ARC-enabled TV to send audio data “upstream”to C399.
The C399 will automatically attempt an ARC audio connection to the TV
whenever the TV announces over CEC that it has become the active source.
If an ARC connection can be established, the C399 will output the ARC
audio signal no matter what source is selected on the C399 and will show
“HDMI ARC” in the front panel display.
NOTE
C399 also supports eARC connection.
IR CHANNEL
The C399 has the capability to operate via Alternate IR channel. This is
useful if you have two NAD products that can be operated by similar
remote control commands. With alternate IR Channel, two dierent NAD
products can be controlled independently in the same zone by setting
each one to a dierent IR channel.
IR Channel Assignment
The C399 and the SR 9 remote control must be set to the same channel.
To change the IR Channel on the C399
While at IR Channel menu, use [a/s] to select through Channel 0 to
Channel7. Stop at the preferred IR Channel setting and press [d] to
complete the selection. C399 IR Channel is defaulted to Channel 0.
To change the IR Channel on the SR 9 remote control
• Include a channel number before the library code. For SR 9, library code
“10” is the default library table for “AMP” device. To select this “AMP”
library table for Channel 0, retain the library code “10”(or“010”).
• If you want to load the “AMP”library table on “Channel 1” prex the
library code with “1” to indicate association with “Channel 1”. Load then
the “AMP”library table using the code “110”. Repeat the same for MP
(130) and TUNER (140).
SAMPLE SETUP OF TWO NAD PRODUCTS ON THE SAME ZONE
C399 and T758 are both defaulted to Channel 0. If [OFF] button is pressed
on the SR9 remote control (or AVR 4 remote control for the T 758), both
products will go to standby mode. Press [ON] and both products will power
up from standby mode.
To prevent both products from simultaneously going in and out of standby
mode along with other common commands, set each one to a dierent
IR channel. In this setup, we will keep T 758 and AVR 4 remote control
defaulted to“Channel 0”. As for C399, we will assign it to “Channel 1”; the
same applies to SR 9.
Set C399 and SR 9 to “Channel 1”via the following procedure.
C399
While at “IR Channel” menu, use the [a/s] to go to“Channel 1” setting. Press
[d] to select “Channel 1”.
SR 9
• Press and hold [AMP] in the DEVICE SELECTOR section of the SR 9.
• While holding down the device button [AMP], press“1”, “1”and“0”using
SR 9’s numeric buttons.
• Press [ENTER] while still holding down the device button [AMP]. The
AMP device selector will ash once to indicate that the library input is
successful.
With both C399 and SR 9 set to“Channel 1”, the C399 can now be
remotely controlled independent of the T 758.
NOTE
Performing Factory Reset for C399 or SR 9 will restore their respective IR
channel setting to “Channel 0”.
