INTRODUCTION

WHAT’S IN THE BOX

Packed with your C 3050 LE you will find:

• Two detachable mains power cord

• SR 10 remote control with 2 AA batteries

• Two antennas

• Mic Assembly with Ferrite Base

• USB MIC Sound Adaptor

• Certificate of Authenticity

• Quick Setup Guide

• SAVE THE PACKAGING
  Please save the box and the packaging that came with your C 3050 LE. Should you move or need to transport your C 3050 LE, this is the safest container to use. We have seen too many otherwise perfect components damaged in transit for lack of a proper shipping carton. So please, save that box!

• CHOOSING A LOCATION
  Choose a location that is well ventilated (with at least several inches to both sides and behind), and that will provide a clear line of sight, within 23 feet/7 meters, between the C 3050 LE’s front panel and your primary listening/viewing position. This will ensure reliable infrared remote control communications. The C 3050 LE generates a modest amount of heat, but nothing that should trouble adjacent components. It is perfectly possible to stack the C 3050 LE atop other components, but the reverse usually should be avoided. It is especially important that sufficient ventilation be provided. If you are contemplating placing the C 3050 LE within a cabinet or other furniture, consult your NAD audio/video specialist for advice on providing adequate airflow.

• NOTES ON INSTALLATION

• Place your C 3050 LE on a firm, level surface.

• Avoid placing the unit in direct sunlight or near sources of heat and damp.

• Do not place the unit on a soft surface like a carpet.

• Allow adequate ventilation.

• Make sure the unit is switched off before making any connections.

• Use high quality leads and sockets for optimum performance and reliability.

• Ensure that leads and sockets are not damaged in any way and all sockets are firmly pushed home.

• Should water get into your C 3050 LE, shut off the power to the unit and remove the plug from the AC socket. Have the unit inspected by a qualified service technician before attempting to use it again.

• Use a dry soft cloth to clean the unit. If necessary, lightly dampen the cloth with soapy water. Do not use solutions containing benzol or other volatile agents.

• DO NOT REMOVE THE COVER. THERE ARE NO USER-SERVICEABLE PARTS INSIDE.

• BARE WIRES AND PIN CONNECTORS

• WARNING: The terminals marked with this symbol are hazardous live. External wiring connected to these terminals requires installation by an instructed person or the use of ready-made leads or cords.

• Bare wires and pin sockets should be inserted into the hole in the shaft of the terminal. Unscrew the speaker terminal plastic bushing until the hole in the screw shaft is revealed. Insert the pin or bare cable end into the hole and secure the cable by tightening down the terminal bushing. Ensure bare wire from the speaker cables does not touch the back panel or another socket. Ensure that there is only 1/2 (1cm) of bare cable or pin and no loose strands of speaker wire.

GETTING STARTED

FACTORY RESET

Factory Reset is recommended if your C 3050 LE is not functioning or the internet firmware upgrade has failed. All customizations including Wi-Fi network configuration,  shares, and saved playlists will be lost. They have to be re-created once the factory reset is completed.
C 3050 LE can be factory reset or restored to factory default settings using the following method.

1. With the C3050 LE in operating mode, switch OFF the rear panel POWER switch.
2. Press and hold the front panel POWER button and while doing so, switch ON the rear panel POWER switch. Do not release the hold of the POWER button.
3. Hold down the POWER button for more than 30 seconds or until the VU meter illuminates twice (white with yellow background). This indicates that the factory reset is initiated.
4. The front panel Power LED indicator will turn amber indicating that the C 3050 LE is restored to its factory default settings. Wait for at least 1 minute before powering up the unit.

IMPORTANT

Releasing the front panel POWER button at any time before VU meter illuminates twice will cancel the factory reset and leave the C 3050 LE Upgrade Mode. Just start again the procedure for Factory Reset.

USING THE SR 10 REMOTE CONTROL LIBRARY

The SR 10 can store a different library of default NAD codes for each of its DEVICE SELECTOR “pages.” If the original default library does not control your NAD CD player, BluOS player, or Tuner, follow the procedure below to change the library code. Refer also to the table below for a list of applicable NAD Library Codes with their corresponding NAD models.
LOAD ANOTHER LIBRARY CODE

Example : Load NAD DVD Player T 517 library codes to SR 10’s “AUX” device.

1. 1 Press and hold [AUX] in the DEVICE SELECTOR section of SR 10.
2. 2 While holding down the device button AUX, press “2” and “2” using SR 10’s numeric buttons. “22” is the corresponding library code for T 517.
   Press [ENTER] while still holding down the device button (AUX). The AUX device selector

will flash once to indicate that the library input is successful. Both the device selector button (AUX) and [ENTER] can now be released.

OPERATION

DIRAC LIVE

The proprietary Dirac Live is integrated with your C 3050 LE. Connect to the rear panel USB port the assembled USB MIC Sound Adaptor and Mic Assembly with Ferrite Base for Dirac setup and calibration.
Dirac Live is a patented room correction technology that not only corrects the frequency response but also the impulse response of room loudspeakers. Dirac Live provides true impulse response correction over a large listening area, improving the depth, positioning and distinction of individual voices and instruments.
Using multiple measurement and mixed phase correction, Dirac Live helps create a natural, realistic and transparent sound with tighter bass and reduced room modes, in a way previously not possible.
For Dirac Live Setup and Calibration guidelines, go to support.nadelectronics.com and search for Dirac Setup
