AUTO STANDBY

Auto Standby feature is an integral feature of C 389 that conforms to
European ecodesign regulations. The C 389 can be setup to automatically
go to standby mode if there is no user interface interaction and no active
source input within 20 minutes.

On: C 389 switches to standby mode at lowest power consumption
(less than 0.5W) if there is no user interface interaction and no active
source input within 20 minutes.

O: C 389 remains at operating mode even if there is no user interface
interaction and no active source within 20 minutes.

NETWORK STANDBY

OPERATION

USING C 389

eARC is the default mode for C 389 and will fallback to ARC if no eARC
connection happens.

IMPORTANT!

• Ensure that the audio setting/format of eARC-connected devices to
C389 is set to PCM only.

• Only audio output signal from a connected TV is supported by C389’s
HDMI eARC port.

IR CHANNEL

The C 389 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 different NAD
products can be controlled independently in the same zone by setting
each one to a different IR channel.

ENGLISH

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

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-configure
itself to respond to the command.

CEC Power O: C 389 cannot be powered up or sent to standby mode
by a CEC-enabled device.

CEC Power On: CEC-enabled device can power ON/OFF the C 389.

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 389 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.

IR Channel Assignment

The C 389 and the SR 10 remote control must be set to the same channel.

To change the IR Channel on the C 389

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 389 IR Channel is defaulted to Channel 0.

To change the IR Channel on the SR 10 remote control

• Include a channel number before the library code. For SR 10, 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” prefix 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 389 and T 758 are both defaulted to Channel 0. If [OFF] button is pressed
on the SR 10 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 different
IR channel. In this setup, we will keep T 758 and AVR 4 remote control
defaulted to “Channel 0”. As for C 389, we will assign it to “Channel 1”; the
same applies to SR 10.

Set C 389 and SR 10 to “Channel 1” via the following procedure.
