Mdc Classic Upgrade Slot; Dd Hdmi 1 (Direct Digital Hdmi); Dd Ap 1 (Direct Digital Analog-Phono) - NAD C 390DD Owner's Manual

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 two optional MDC modules – the DD HDMI 1 and the DD
AP 1 modules. Remove covers to install the optional Modular Design
Construction (MDC) modules. Consult with your NAD dealer on how to
procure the DD HDMI 1 and the DD AP 1 modules and their consequent
installations to the C 390DD.

DD HDMI 1 (DIRECT DIGITAL HDMI)

The DD HDMI 1 offers three HDMI input terminals and one HDMI output
with video pass through. With DD HDMI 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 definition
theater presentation. DD HDMI 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, preamplifier 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 configurations are followed – Pin 1: Ground, Pin 2:
Positive (signal live) and Pin 3: Negative (signal return).
