Choose a location for your NAD C 338 that is well-ventilated. To maintain proper ventilation, be sure to leave a space around the unit (from the largest outer dimensions including projections) that is equal to, or greater than shown below:

• Left and Right Panels: 10 cm

• Rear Panel: 10 cm

• Top Panel: 10 cm

The location should also provide a clear line of sight, within 25 feet / 8 meters, between the NAD C 338’s front panel and your primary listening/viewing position to ensure reliable infrared remote control communications.

To restore the NAD C 338 to its factory settings, press and hold the front panel’s SOURCE > button until the display shows “C3”. Release the SOURCE > button to complete the restoration.

Important Note: When you restore your NAD C 338 to its factory default settings, all settings or configurations you have set up will also be reset or deleted.

To operate the NAD C 338, the rear panel POWER switch must be set to ON and the power cord must be plugged into a power source.

• **From Standby Mode:** Press the front panel Standby button to switch ON the C 338 from standby mode. The Power indicator will change color depending on the status.

• **To Standby Mode:** Pressing the Standby button again switches the C 338 back to standby mode. The Power indicator will change to amber.

• **Master Power:** To completely turn off the amplifier, use the POWER switch on the rear panel. If you do not intend to use the C 338 for long periods of time, switch off the POWER switch.

The Power Indicator on the NAD C 338 changes color to show its current status:

To stream music, a Wi-Fi connection must be established. The following steps use an Android device as a reference; iOS device steps are similar.

1. Download the Google Home App from the App store for your Apple iOS or Android device.

2. Set the rear panel POWER switch to ON.

3. Press the front panel Standby button. Wait for the Power Indicator color to settle at fast blinking blue, which indicates it is in Wi-Fi setup mode (Hotspot mode). If the indicator turns solid blue, a Wi-Fi connection is already established.

4. Open the Google Home App on your device.

5. The app will discover the NAD C 338 (e.g., “NADAmplifierDF432A Needs setup”). Select “SET UP”.

6. The app will confirm the amplifier has been found. Select “CONTINUE”.

7. Your mobile device will connect to the amplifier’s temporary Wi-Fi hotspot.

8. The app will then play a test sound through your speakers. If you hear the sound, select “I HEARD IT”. If not, select “TRY AGAIN” after checking your speaker connections and volume level.

9. Name your amplifier (e.g., “Bedroom Speakers”) or keep the default name. Select “CONTINUE”.

10. Select your preferred Wi-Fi network from the list.

11. Enter your Wi-Fi password and select “CONTINUE”.

12. The NAD C 338 will now connect to your Wi-Fi network. This completes the Wi-Fi setup. You can now select “LEAVE SETUP” or “SIGN-IN” to link your Google Account.

With a successful Wi-Fi connection, you can stream music to your NAD C 338. The control media device and the C 338 must be on the same Wi-Fi network.

Using Chromecast built-in:

Tap or click the Cast button from your favorite music apps or browser to start casting to your C 338. You can adjust the volume or change the song directly from your control device.

Using Spotify Connect (Example):

1. Play some music in the Spotify app.

2. Tap the Now Playing bar at the bottom of the screen.

3. Tap “DEVICES AVAILABLE”.

4. Select your NAD C 338 (e.g., NAD_C338_08D01C) from the list to start playing Spotify through the amplifier.

For other music services, check their setup procedure on how to connect to a streaming device.

1. Ensure the Bluetooth antenna is connected to the BT antenna terminal on the rear panel.

2. On your iOS, Android, or other Bluetooth device, go to Settings -> Bluetooth and scan for Bluetooth devices.

3. Select the unique device ID of your C 338 from the list of available devices in your Bluetooth settings.

4. Pair or connect your device to the C 338. Upon successful pairing, you can start music playback from your Bluetooth device.

The front panel display indicator “Wi-Fi/BT” will illuminate when music is streamed via Bluetooth. Note that music playback via Network (Wi-Fi) and Bluetooth can only happen one at a time. If you start Bluetooth playback while Wi-Fi streaming is active, the Wi-Fi stream will be stopped or overlapped.

The Auto Standby feature automatically puts the NAD C 338 into standby mode if there is no user interface interaction and no audio input for 20 minutes.

To Enable/Disable Auto Standby mode:

In operating mode, press and hold the SOURCE > and BASS EQ buttons together until “ON” or “OFF” is shown in the front panel display. “ON” is the default setting.

With Auto Standby set to ON, there are two types of standby mode:

• **Network Mode:** If there is no user interaction or active source for 20 minutes, the unit switches to a reduced power standby mode (less than 2W). Network and Bluetooth connections are maintained. The C 338 can be woken up by playing a network or Bluetooth source, pressing source/volume buttons, or using the Standby button.

• **ECO Mode:** This mode offers the lowest power consumption (less than 0.5W). To activate ECO mode, press and hold the front panel Standby button until the display shows a flashing “OFF”. The C 338 will then enter ECO standby mode. In ECO mode, the unit can only be switched back to operating mode by pressing the front panel Standby button or the [ON] button on the remote control.

The Auto Sense feature enables the NAD C 338 to wake up from standby mode when it detects an active digital or analog audio source input.

To Enable/Disable Auto Sense mode:

While in operating mode, press and hold the BASS EQ button until “A” (On) or “-” (Off) is shown in the front panel display.

• **A (On):** Unit wakes up from standby when triggered by an active audio source.

• **- (Off):** Unit remains in standby even if an active audio source is detected.

Important Note: With Auto Sense set to “On”, the unit will not go into standby mode as long as there is an active audio source input. To allow the unit to enter standby, you must shut down or pause your audio source(s), or set Auto Sense to “-” (Off).

The Infrared (IR) Learning feature allows the NAD C 338 to learn commands from any non-NAD remote control. There are twelve commands (F1 to F12) that can be learned.

1. Press and hold the front panel BASS EQ and < SOURCE buttons at the same time until “F1” appears on the display. This indicates the unit is in IR learning mode.

2. Use the front panel < SOURCE or SOURCE > buttons to toggle through the functions F1, F2…F12.

3. Select the function you want to learn (e.g., toggle to “F5” for Volume Up).

4. Press the BASS EQ button. The selected function (“F5”) will begin to flash.

5. While pointing your non-NAD remote control at the front panel display, press the corresponding button you want to assign to this function.

6. “F5” will stop flashing, stay solid briefly, and then the display will show the next command (F6). The solid “F5” indicates the code has been learned.

7. Repeat the process to learn other IR remote control codes.

8. To save the learned codes and exit IR learning mode, press and hold the front panel BASS EQ and < SOURCE buttons until the display reverts to showing the volume level.

Upon powering up and configuring the Wi-Fi connection, your NAD C 338 will begin an installation process to ensure it has the newest device software. Do not interrupt the power supply or enter new commands during this process.

• The display will initially show the progress of the software download in percentage (e.g., 90%).

• The C 338 will then automatically update with the downloaded software. The update progress is indicated by progressive “-” (dash) marks on the display.

• When the display shows solid dashes (“- – – -“), the process is complete and the unit will automatically restart.

This process is initiated periodically to keep the NAD C 338 updated with the latest software.

All specs are measured according to IHF 202 CEA 490-AR-2008 standard. THD is measured using AP AUX 0025 passive filter and AES 17 active filter.
