NAD 2400 - NAD 2400 Bridged Mode Performance; Bridged Monophonic Power Output Specifications; Bridged Monophonic Dynamic Headroom Metrics; NAD 2400 Physical Dimensions and Weight

BRIDGED (MONOPHONIC) MODE
CONTINUOUS AVERAGE POWER OUTPUT INTO 300 W (24.7 dBW)*
8 OHMS 7
(Min. RMS power , 20H2-20kHz,
with no more than the
rated distortion)
IHF Dynamic Headroom at 8 ohms +4.3dB
IHF Dynamic Power (maximum | 8 ohms 800 W (29 dBW)
short-term power ) 4ohms 880 W (29.4 dBW)
*In some countries local regulations require that bridged 8 ohm power be measured with the speaker
impedance switch in the 4 ohm position resulting in a bridged RMS output of 200W(23dBW).

IMPORTANT NOTES
1.
Before
adjusting,
remove
input
signal
and
load,
and
set
speaker
impedance
switch
to
80
(HIGH):
reset
to
4Q
(NORMAL)
when
finished.

2.
These
adjustments
are
always
necessary
after
repair
to
main
amplifier.
3.
After
repair,
it
is
recommended
to
use
current
limiter
(200-250W
lightbulb)
in
mains
line,
for
initial
turn-on.
A. CENTER VOLTAGE CHECK
1.
Connect
DVM
from
Ground
to
R436,
L
chan
(R486,
R
chan),
2.
Turn
power
on,
and
check
for
reading
of
OV
+100mVDC.
B. IDLE CURRENT ADJUSTMENT
1.
Connect
DVM
from
TP401
to
TP402,
L
chan
(TP451,
TP452
R
chan).
2.
Adjust
R418,
L
chan
(R468,
R
chan)
for
reading
of
14mV
+1mVDC.
C. FINAL ADJUSTMENT
1. Leave power on minimum 5 minutes.
2.
Repeat
center
voltage
check
and
idle
current
adjustment.
