10  +12V TRIGGER IN/OUT

+12V TRIGGER OUT

• 

The +12V TRIGGER OUT is used for controlling external equipment 
equipped with a +12V trigger input.

• 

Connect this +12V TRIGGER OUT to the other equipment’s 
corresp12V DC input jack using a mono cable with 3.5mm 
male plug.

• 

This output will be 12V when the C 298 is ON and 0V when it is 
either OFF or in standby mode.

+12V TRIGGER IN

• 

With this input triggered by a 12V DC supply, the C 298 can be 
switched ON remotely from standby mode by compatible devices 
such as amplifiers, preamplifiers, receivers, etc. If the 12V DC supply 
is cut off, the C 298 will return to standby mode. 

• 

Connect this +12V Trigger input to the remote device’s 
corresp12V DC output jack using a mono cable with 
3.5mm male plug. The controlling device must be equipped with a 
+12V trigger output to use this feature.  

11  BRIDGE MODE

The C 298 amplifier can be configured to be MONO (Bridge Mode), 
more than doubling its output power. This way, the C 298 can be used 
as part of a high power stereo or home-theatre system, by connecting 
additional power amplifiers.

• 

In BRIDGED MODE (switch at ON (MONO) setting), the C 298 will 
produce approximately 620W into an 8 ohm loudspeaker. In this mode, 
the amplifier sections will react as though the speaker impedance 
has been halved. Low impedance speakers (under 8 ohms) are not 
recommended when using Bridge Mode as these may cause the 
amplifier’s thermal cut-out to operate if played at high levels.

• 

Set BRIDGE MODE switch to the “ON (MONO)” position and connect 
the speaker to the terminals marked “L +” and “R-” ensuring that the 
“L+” is connected to the “+” terminal of your speaker and the “R-” is 
connected to the speaker’s “ - ” terminal.

• 

Set BRIDGE MODE switch to OFF (Stereo) for normal operation.

IMPORTANT NOTE

 

If C 368 is the signal source, connect only C 368 Right channel PRE OUT 
to C 298 LEFT input (both C 368 and C 298 in BRIDGE mode).  Never use 
C 368 Left channel PRE OUT to drive C 298 LEFT input. 

12 SPEAKERS 

• 

Connect C 298’s Right speaker terminals marked “R +” and “R-” to 
the corresponding “+” and “-“ terminals of your designated right 
speaker. Repeat the same for C 298’s Left speaker terminals and 
corresponding left speaker. 

• 

Double check the speaker connections before powering up the C 298.

IMPORTANT NOTES

•  The blue terminals must never be connected to ground (earth).
•  Never connect the blue terminals together or to any common ground 

device.

•  Do not connect the output of this amplifier to any headphone adapter, 

speaker switch or any device that uses common ground for left and 
right channels.

NOTES

•  Use 16 gauge (American Wire Gauge or AWG) or lower stranded wire. 

Connections to the C 298 can be made with banana-type plugs.

•  Bare wire or pins can also be used by loosening the terminal’s plastic 

nut, making a clean, neat connection and re-tightening. To minimize 
the danger of a short circuit, ensure that only 1/2-inch of exposed wire 
or pin is used to connect and no loose strands of speaker wire.

13 POWER 

• 

Supplies the AC mains power to the C 298.

• 

When the POWER switch is set to ON position, the C 298 goes to 
standby mode as shown by the amber status condition of the front 
panel Power indicator.

• 

Press the front panel Standby button to switch ON the C 298 from 
standby mode.

• 

If you do not intend to use the C 298 for long periods of time (such 
as when on vacation), switch off the POWER switch.

• 

With POWER switched off, the front panel Standby button cannot 
activate the C 298.

14  FUSE HOLDER  

• 

Only qualified NAD service technicians can have access to this fuse 
holder. Opening this fuse holder may cause damage thus voiding 
the warranty of your C 298.

15  AC MAINS INPUT

• 

The C 298 comes supplied with two separate mains power cords. 
Select the mains power cord appropriate for your region.

• 

Before connecting the plug to the mains power source, ensure that 
it is firmly connected to the C 298’s AC Mains input socket.

• 

Always disconnect the mains power plug from the mains power 
source before disconnecting the cable from the C 298’s AC Mains input 
socket.
