Note: NAC-N preamplifier outputs are intended for connection to a power amplifier or a subwoofer. Preamplifier outputs
always reflect the selected input. Your local Naim retailer will be able to supply appropriate cables for power amplifier or
subwoofer connection if necessary.
2.2 Audio Signal Connections
Table 2.2.1 lists the audio inputs and outputs provided
on each NAC-N preamplifier. Always use high quality
interconnect cables to connect inputs and outputs.
Note: Post volume control output signals are affected
by volume and balance adjustments. Pre volume control
output signals are unaffected by volume and balance
adjustments and must be routed via a volume control
before reaching a power amplifier.
