MDC CLASSIC UPGRADE SLOT

The delivery format of digital content is constantly changing in pure

digital systems like the C 390DD. Each of these formats typically requires

specialized hardware and software, often with licensed IP and content copy

protection.

In order to address such continuous technological evolution, NAD’s

design team placed all digital interface circuitry of the C 390DD on easily

upgradable modules. NAD calls this the Modular Design Construction

(MDC). The C 390DD includes one MDC module already – the DD USB 1

(Direct Digital USB) which has Type A and Type B USB input terminals.

There are other optional Modular Design Construction (MDC) modules that

can be integrated with the C 390DD by installing them on the vacant slots

in the rear panel. The following are the optional MDC modules

• DD HDMI-1 (HDMI) with 3 HDMI inputs (stereo only, no surround

decoding) and one 1 HDMI Output (Video pass through).

• DD AP-1 (Direct Digital Analog Phono) with SINGLE-ENDED stereo,

BALANCED stereo and PHONO inputs.

• DD BluOS featuring BluOS, a complete digital music solution that allows

the integration of Hi-Res audio, network streaming and music control

using the BluOS app.

DD HDM‑1 (DIRECT DIGITAL HDMI)

The DD HDM-1 oers three HDMI input terminals and one HDMI output

with video pass through. With DD HDM-1 installed, the C 390DD can be

the heart of a “Video 2.0” system using the mandatory 2 channel linear

PCM soundtrack from Blu-ray or DVD to make a compelling high denition

theater presentation. DD HDM-1 is fully 3D video compatible but without

surround sound decoding or video processing.

A HDMI OUT: Connect the HDMI Monitor OUT

to a HDTV or projector with HDMI input.

B HDMI 1 -3: Connect the sets of HDMI input

to the HDMI OUT connectors of source

components such as DVD player, BD player or

HDTV satellite/cable box.

WARNING

Before connecting and disconnecting any HDMI cables, both the

C 390DD and the ancillary source must be powered OFF and unplugged

from the AC outlet. Failure to observe this practice may cause permanent

damage to all equipment connected via HDMI sockets.

DD AP‑1 (DIRECT DIGITAL ANALOG‑PHONO)

DD AP-1 uses high quality Analog-to-Digital conversion to make analog

sources compatible with C 390DD’s pure digital circuitry. The PHONO circuit

has impedance settings for MM and MC with gain automatically set.

The DD AP-1 consists of the line level input terminals – PHONO, SINGLE-

ENDED (ANALOG) and BALANCED.

A PHONO: Input for either a Moving Coil

or Moving Magnet phono cartridge.

Connect the twin RCA lead from your

turntable to this input.

B SE IN (SINGLE-ENDED): Use a twin

RCA-to-RCA lead to connect these

sockets to the left and right analog

output of a CD player, preamplier or

processor.

C PHONO GROUND CONNECTOR:

Turntables normally includes a single

wire earth lead. Use the C 390DD

phono ground connector to connect this lead. Unscrew the

terminal to expose the hole that will accept the lead. After insertion,

tighten the terminal to secure the lead.

D BALANCED: Connect XLR audio source to these connectors. Ensure

that proper pin congurations are followed – Pin 1: Ground, Pin 2:

Positive (signal live) and Pin 3: Negative (signal return).

DD BluOS

BluOS is a music management software developed by NAD’s sister brand,

Bluesound. Integrating DD BluOS will add BluOS network and internet

music streaming with advanced music management to your NAD C 390DD.

Refer to the MDC DD BluOS Mounting Instructions and Conguring

DDBluOS on how to install and integrate the DD BluOS with the C 390DD.

IMPORTANT NOTE

BluOS audio cannot be streamed through digital output terminals.

BluOS PLAYBACK CONTROLS

Using the AVR 4 remote control, the following control buttons are

applicable for BluOS playback. Set DEVICE SELECTOR to MP for BluOS

playback control.

4 : Resume playback from pause mode.

j : Pause current playback.

9 : Skip back to the beginning of current song.

0 : Skip forward to the next song.

RPT: Repeat track (song), playlist or repeat o.

DISP: Toggle to display applicable information about current song,

broadcast or media.

BluOS SETUP MENU

The BluOS Setup menu has to be enabled after integration of the DD BluOS

module. There are two ways to enable the BluOS Setup menu.

Using the front panel buttons

• Press and hold together front panel buttons [SOURCE s] and [ENTER]

Using the AVR remote control

• Press and hold [DISP] button
