or respectively increases or decreases the Volume setting. The
motorised Volume Control on the front panel will indicate the level set.
Other than the commands relating to the NAD C 162 amplifier itself,
there are other buttons which will operate most NAD CD players and
Cassette decks equipped with NAD Link:
TUNER CONTROL
(for use with NAD Tuner)
TUNE or scans respectively higher or lower station frequencies for
both AM and FM.
PRESET or selects respectively higher or lower number station
preset.

BI-AMPING
Some loudspeakers have separate connection terminals for the LF (Low
Frequency) and HF (High Frequency) sections of the speaker. This facility
allows to "Bi-amp" these speakers, where a separate power amplifier is
used for the LF and HF section, which may improve overall sound quality.
The NAD C 162 provides two sets of pre amplifier outputs (PRE OUT 1
& 2) to facilitate the connections for Bi-amping. Moreover, the level from
PRE OUT 2 can be reduced in relation to PRE OUT 1 to accommodate
power amplifiers with different gain (amplification factor).
To set up the C 162 with power amplifiers first decide which power
amplifier has the highest gain. This is easily done by comparing the
loudness level of the power amplifiers in an identical system (keep the
volume control at the same level; use the same source and speakers).
The amplifier that plays louder has the highest gain (note that this does
not need to be the more powerful amplifier of the two).
Connect the amplifier with highest gain to the PRE OUT 2 (No. 12)
sockets; the other power amplifier to the PRE OUT 1 (No. 11) sockets.
From the maximum level position (0dB), use the VOLUME PRE OUT 2
control (No. 13) to reduce the output level of PRE OUT 2 so that the
volume level of both power amplifiers is exactly matched.
CAUSE
• Power AC lead unplugged or power not
switched on
• Tape 1 Monitor selected
• Mute on
• Power amplifier is switched off
• Headphones inserted
• Balance control not centered
• RCA lead to power amplifier not properly
connected or damaged.
• Input lead disconnected or damaged
• No signal
• Hum on Phono input.
• Weak or Distorted signal
• Batteries flat, or incorrectly inserted
• IR transmitter or receiver windows obstructed
• IR receiver in direct sun or very bright ambient
light
SOLUTION
• Check if AC lead is plugged in and power
switched on
• De-select Tape 1 Monitor mode
• Switch off Mute
• Switch power amplifier on
• Unplug headphones
• Center Balance control
• Check leads and connections
• Check leads and connections
• Check MM-MC switch set correctly
• Check phono earth lead is connected
• Check the turntable is connected to the correct
MM or MC phono input
• Check or replace batteries
• Remove obstruction
• Place unit away from direct sun, reduce amount
of ambient light
