Operation Manual
10 MAIN IN: Connections to an external pre-amplier or processor, such
as a surround-sound decoder. In normal use, this should be connected
to PRE OUT sockets (No. 9) with the links supplied. To connect your NAD
C 725BEE to external processor or pre-amplier, remove rst these links.
Use a twin RCA-to-RCA lead to connect the left and right “Audio Output”
of the pre-amp or processor to the Main In sockets.
NOTE
Always turn the C 725BEE o before connecting or disconnecting
anything from to PRE OUT and MAIN IN sockets.
11 SUBW (SUBWOOFER) OUT: Connect this output to a powered (active)
subwoofer or to a power amplier channel driving a passive system.
12 SPEAKERS A, B: The C 725BEE is equipped with two sets of speaker
connectors. Use the Speakers A terminals for the “main” speakers and
use the Speakers B terminals for a second pair, for example, extension
speakers located in another room.
Connect the right speaker to the terminals marked ‘R +’ and ‘R-’ ensuring
that the ‘R+’ is connected to the ‘+’ terminal on your loudspeaker and
the ‘R-’ is connected to the loudspeaker’s ‘-’ terminal. Connect the
terminals marked ‘L+’ and ‘L-’ to the left speaker in the same way.
The C 725BEE is designed to produce optimum sound quality when
connected to speakers with impedances within its operating range. Please
make sure that all the speakers are rated 4 ohms minimum per speaker.
NOTE
Use stranded wire of at least 16 gauge (AWG); specialized speaker cable
maybe valuable (consult your NAD audio specialist). Connections to
the C 725BEE can be made with banana plugs (120V version only) or
by using bare wire or pins. Use the transverse hole through the post for
bare-wire or pin connections. By loosening the terminal’s plastic nut,
make a clean, neat connection and re-tighten carefully. To minimize the
danger of short-circuit, ensure that only 1/2-inch of exposed wire or pin
is employed when connecting.
13 SOFT CLIPPING™: Enables NAD’s proprietary Soft Clipping circuitry
on all channels. At ON position, Soft Clipping gently limits the output
of the C 725BEE to minimize audible distortion should the Receiver
be overdriven. Soft Clipping may simply be left ON (“S.CLIP” icon will
illuminate in the VFD) at all times to reduce the likelihood of audible
distortion from excessive volume settings. However, for critical listening
and to preserve optimum dynamics, you may wish to defeat it by
setting this switch OFF.
14 POWER SWITCH: The POWER switch supplies the master AC mains
power for the C 725BEE. When this switch is at ON position, the
C 725BEE is in standby mode as shown by the amber status condition of
the standby LED. If you intend not to use the C 725BEE for long periods
of time (such as when on vacation), switch the POWER switch to the
OFF position. When the POWER switch is at OFF position, the front
panel power button, SR 8 remote control or ZR 5 cannot activate the
C 725BEE.
15 SWITCHED AC OUTLET: This convenience outlet can supply switched
power to another component or accessory. With the Power switch at
the rear panel set to ON position, this outlet is powered ON or OFF by
the front panel STANDBY switch or by the SR 8’s [ON/OFF] buttons. The
total draw of all devices connected to this outlet must not exceed 120
watts for 120V version and 115 watts for 230V version.
16 RS-232: Connect this interface via RS-232 serial cable (not supplied) to
any Windows® compatible PC to allow remote control of the C 725BEE
through NAD’s proprietary PC software or other compatible external
controllers. NAD is a certied partner of AMX and Crestron and fully
supports these external devices. See your NAD audio specialist for more
information.
17 MP DOCK: The C 725BEE is equipped with a data port in the rear panel
where an optional “NAD IPD 1 Dock with iPod” (NAD IPD 1) can be
plugged in. Connect the “MP DOCK (DATA PORT)” jack of the C 725BEE
to the corresponding “DATA PORT” socket of the optional NAD IPD 1.
Refer also to LISTENING TO YOUR iPod PLAYER under the OPERATION
main heading.
NOTE
C 725BEE is compatible with NAD IPD 1 and later NAD IPD variants.
Check with your dealer or NAD audio specialist for other versions of NAD
IPD compatible with C 725BEE.
18 FM ANTENNA INPUT: The supplied wire “dipole” FM antenna will
connect to the FM connector using the supplied “balun” adapter. It will
usually work best when mounted on a vertical surface such as a wall,
with arms fully outstretched forming a horizontal “T” perpendicular to
the origin point of the signal. Refer also to the item ABOUT ANTENNAS
at the LISTENING TO AM/FM RADIO section of the OPERATION page.
19 AM ANTENNA INPUT: Connect the supplied AM loop antenna to
these terminals. If an external AM antenna is used, make connections to
the AM and GND terminals in accordance with the instructions supplied
with the antenna. Refer also to the item ABOUT ANTENNAS at the
LISTENING TO AM/FM RADIO section of the OPERATION page.
20 DAB MODULE INPUT PORT (230V version only): Plug-in the other
end of the Mini-Din connector from the NAD DAB Adaptor DB 1 module
output port into this socket. The C 725BEE is compatible only with NAD
DAB Adaptor DB 1 so check with your NAD dealer for this module’s
availability. With DAB, you can receive CD-like quality programs without
any annoying interference and signal distortion. Refer also to “LISTENING
TO DAB RADIO” under the “OPERATION” main heading.
21 AC LINE CORD: Plug the AC power cord into a live AC wall socket.
Connect only to the prescribed AC Outlet, i.e., 120V 60 Hz or 230V 50 Hz.
Make sure all connections have been made before connecting to mains.
