PREAMPLIFIERS, AMPLIFIERS AND
MIXERS FOR USE WITH THE NAD-911.
In most installations using the NAD-911, the hi-fi
preamplifier is used to select the appropriate music
source and for every-day adjustment of the music vol-
ume in the venue.
Any hi-fi preamplifier can be used with the NAD-
911 or alternatively an integrated hi-fi amplifier can be
used providing it has a ‘pre-amp’ output. NAD sup-
plies a range of preamplifiers and integrated ampli-
fiers suitable for use with the NAD-911.
Some installations will use a mixer instead of a pre-
amp and this is connected and used with the NAD-
911 in exactly the same way as a preamplifier.
The channel outputs of the NAD-911 will work with
both hi-fi and professional power amplifiers. There is
a range of NAD single channel, stereo or multi-chan-
nel power amplifiers that are suitable to work with the
NAD-911.
You should ensure that the power output level of
the power amplifiers used in the installation matches
the capabilities of the loudspeakers. If you are using
a power amplifier with its own volume control, during
installation set the NAD-911 LEVEL controls (3) to
the 12 O’clock position and then adjust the power
amplifier’s volume control so that the sound level
from the speaker is about right for normal use.
CABLES.
The amplifiers can be placed near the NAD-911
using short signal leads and long speaker leads.
Generally you will get better performance from the
installation if the amplifiers are placed nearer the
speakers using longer signal leads and shorter
speaker leads. In either case to achieve best perfor-
mance all speaker cables should be high quality large
diameter speaker cables (16 gauge or more) and all
signal leads should be high quality co-axial cable.
Cable lengths of up to 22nF total capacitance can
be used to connect the NAD-911 Variable Output to
an amplifier.
CONNECTING INPUTS.
A simple installation uses a CD player and
Cassette Deck connected to the hi-fi preamplifier. In a
stereo system the hi-fi preamplifier is connected to
INPUT sockets (4) of Channels 1 & 2 of the NAD-
911. In a mono system connect the preamplifier to
the INPUT of Channel 1 only.
Connect the Microphone to the MIC IN (1).
LINKING CHANNELS.
Feeding the music signal to every channel in the
distribution preamplifier is done by using links
between the outputs of each channel to the inputs of
the other channels.
