SETTINGS

The "Settings" main menu allows you to configure or show the following features:

• Tone Controls
• Treble
• Filters
• Speaker Channel
• Dimmer
• Auto Standby
• IR Channel
• Volume Display Mode
• Firmware Upgrade
• BT Work Mode
• Bass
• Balance
• Pre Out/Subwoofer
• Temporary Display
• Network Standby
• Auto Sense
• IR Learning Device
• Firmware Version
• MDC Card Upgrade

TONE CONTROLS

Tone controls allow the boosting or reduction of particular audio frequencies. The tone control levels, Bass and Treble, can be turned on or off.
On: Tone control levels are active. At Tone Controls On, Bass and Treble control levels are available for configuration.
Off: Tone controls levels are bypassed. At Tone Controls Off, Bass and Treble control levels become unavailable or turned off from the Settings menu.

BASS, TREBLE, BALANCE

Bass and Treble controls only affect the low bass and high treble leaving the critical midrange frequencies free of coloration.

• Use [ ] to boost or cut Bass or Treble levels within ±7 dB range.
  

Balance control adjusts the relative levels of the left and right speakers.

• Press [ ] to shift the balance to the right or [ ] to shift the balance to the left. Use [a/s] also to recover or even out the balance levels.
• "0 dB" level setting provides equal level to the left and right channels.

FILTERS

Filters provide easy bi-amplification or subwoofer integration by adding the required filters to redirect bass frequencies to the subwoofer.
High Pass: Low pass signal up to 150 Hz is attenuated and over 150 Hz sent to the speakers. This is based from 2nd order Linkwitz-Riley Crossover Filter @150 Hz.

If different crossover filter settings are required, it is recommended to use the filters built into the connected external Powered Subwoofer. Experiment by reversing the polarity of the Subwoofer or use a combination of filters, for example, the High Pass filter built into the C 368 and run full range to the Subwoofer and set the Crossover filter setting on the Subwoofer itself. Note that changing the level can also change the crossover frequency, so experimentation is the only way to get an optimal result.

Full Range: Refers to the whole frequency spectrum capability of your C 368 and speaker system. This is ideally 20 Hz to 20 kHz.

PRE OUT/SUBWOOFER

Pre Out/Subwoofer feature allows you to select the function of the PREOUT or SUBWOOFER terminals.
Pre Out: Configured as Pre Out terminals.
Subwoofer: Configured as Subwoofer terminals.

SPEAKER CHANNEL

SPEAKER CHANNEL enables you to engage or disengage the speakers connected respectively to the SPEAKERS A and SPEAKERS B terminals on the rear panel.

IR CHANNEL

The C 368 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.

IR Channel Assignment
The C 368 and the SR 9 remote control must be set to the same channel.

To change the IR Channel on the C 368
While at IR Channel menu, use the [a/s] to select through Channel 0 to Channel 3. Press [ENTER] to select preferred IR Channel setting. C 368 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" 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
NAD C 368 and NAD C 390DD are both defaulted to Channel 0. If [OFF] button is pressed on the SR 9 remote control (or AVR 4 remote control for the C 390DD), 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 C 390DD and AVR 4 remote control defaulted to "Channel 0". As for C 368, we will assign it to "Channel 1"; the same applies to SR 9.

Set C 368 and SR 9 to "Channel 1" via the following procedure.

C 368
While at "IR Channel" menu, use the [a/s] to go to "Channel 1" setting. Press [ENTER] 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 flash once to indicate that the library input is successful.

With both C 368 and SR 9 set to "Channel 1", the C 368 can now be remotely controlled independent of the C 390DD.

NOTE
Performing a Factory Reset for C368 or SR 9 will restore their respective IR channel setting to "Channel 0".

IR LEARNING DEVICE
