OUT to a spare line level input (eg ‘Aux in’) on the
second system. Because of the long leads often
required for Multi Room installations, for optimum
performance use high quality cables for the connec-
tions.
9. NAD-LINK IN OUT
The NAD-Link connector is used to pass commands
from the remote control to and from other units fitted
with NAD-Link connectors. This allows centralised
control of a complete system or gives system contro!
from more than one room. To function with other
units, connect the 917’s NAD-Link OUT to NAD-Link
IN on the other unit. NAD-Link connectors can be
daisy-chained, IN to OUT, so that a whole system
can be controlled from the remote contro! facilities of
one unit.
A single NAD-Link connection from a hi-fi system in a
second room will allow remote control of Multi Room
svstems.
10, 11, 12,13. POWER AMPLIFIERS
The 917 does not contain power amplifier sections,
and needs to be connected to external power ampli-
fiers. These connectors supply the signals for the °
Front Left, Center and Right channel power ampli-
fiers, the Left and Right Surround channels and the
Sub Woofer channel.
The 917 can function as a normal 2-channel stereo
receiver, three channel Front-only Dolby Pro Logic
system or a full surround Dolby Pro Logic system
depending on the number of amplifier channels and
speakers. A Sub Woofer can be added to any of
these modes.
A combination of single channel or stereo power
amplifiers can be used with the 917. Whilst amplifiers
of different powers and types can be used, it is rec-
ommended that Front Left and Right channels and
preferably, the Front Center channels, all use identi-
cal power amplifier sections such as the NAD 214 or
NAD 216. Alternatively, a dedicated six-channel
Home Theater power amplifier such as the NAD 916
can be used. The POWER AMPLIFIER sockets
should be connected to the ‘Line Inputs’ of the power
amplifier. (See the power ampiifier’s instruction infor-
mation for more information regarding connection.)
The relative levels between the channels and the
overall volume level is set by controls on the 917. If
the power amplifier has its own volume controls, set
these to a middie level (approx 12 o’clock position
and these should then remain unaltered during nor-
mal operation.
Connect the Front Left and Right amplifiers channels
to FRONT (10). Connect the Front Center amplifier
channels to CENTER (12). Connect the Surround
Left and Right amplifier channels to SURROUND
(11). These are used in conjunction with the two
DOLBY selectors on the rear panel.
Connect the Sub Woofer amplifier channel to SUB-
WOOFER (15). This is used in conjunction with the
SUBWOOFER selector on the rear panel.
14 SUBWOOFER SELECTOR
The 917's dedicated Sub Woofer output combines
the low frequencies from the Left and Right channels
and is designed to work with a Sub Woofer driven by
its own power amplifier channel. This can either be a
separate Sub-bass speaker and amplifier, or an
‘active’ Sub Woofer which combines amplifier and
speaker into one unit. The SUBWOOFER selector
switch sets the upper frequency limit to the bass sig-
nal being delivered to the SUBWOOFER connector. It
should be set according to the type of Sub Woofer
being used. This is especially useful when a separate
Sub-bass speaker and amplifier are being used,
which does not have low frequency filters.
Small Sub-bass speakers are typically are designed
to reinforce the bass performance rather than go
down to extreme low frequencies. For these types of
Sub Woofer systems, set the selector to 120Hz.
Larger Sub-bass speakers are designed only to work
at very low frequencies, between 20Hz and 60HZz. For
these types of Sub Woofer systems set the selector
to 60Hz.
Most active Sub Woofers have their own built-in filter-
ing circuits. In these cases, select the FLAT position,
which delivers an un-filtered signal to the Sub
Woofer. This avoids using two filtering circuits in the
Sub Woofer chain. See your Active Sub Woofer or
Sub-bass speaker’s instruction manual for further
information about performance and filtering require-
ments.
15. AC POWER CORD
Plug the AC power cord into a live AC socket. The
‘Standby’ indicator on the power switch is illuminated
when power is being supplied to the 917. For U.S.
only versions: In standby, the Switched AC conve-
nience outlets will be off and the Unswitched AC con-
venience outlet will continue to supply power.
16. AC OUTLETS (US version only)
The AC power of cords other units in the audio sys-
tem can be connected directly to the convenience AC
outlets. The single UNSWITCHED outlet will supply
power continually as long as the 917 is connected to
a live AC socket. When the 917 is switched off, units
connected to the two SWITCHED outlets will be also
switched off .
The UNSWITCHED Outlets should be used with units
with a COMBINED power consumption of no more
than 525 Watts (4.8A). The SWITCHED outlet should
be used with a unit that draws no more than 525
watts (4.8A)
17. MONITOR VIDEO OUTPUT
Composite (line) and S-VHS outputs for viewing
video sources connected to LD, VCR1 or VCR2.
Using a phono lead, connect the ‘Video Line In’ on
the TV or monitor to the MONITOR VIDEO OUTPUT.
Alternatively, if the TV or monitor has an S-VHS
input, use a S-VHS lead to connect its S-VHS input to
MONITOR VIDEO OUTPUT. This output can also be
used as an additional recording output if required.
Video monitoring must then be done via the output of
the video recorder.
18. VCR2 VIDEO OUTPUT
Composite (line) and S-VHS outputs for recording
video sources connected to LD or VCR1. Using a
