MP3 Input
2
This source input allows you to connect a portable audio device such
as an MP3 player, plugged into either the rear panel Phono/RCA input
pair (labelled 'S1') or the front panel 3.5mm stereo-jack input (labelled
'MP3 In').
Press the S1 button on the front panel to select the input, or insert a
device into the front panel socket which automatically selects the input
and overrides the rear Phono/RCA sockets.
Phones
3
Allows for the connection of headphones with a ¼" jack plug connector.
Headphones with an impedance of between 32 and 600 ohms are
recommended. When the headphones are connected, the output to the
loudspeakers is switched off.
Speaker B
4
Turns on/off the secondary set of loudspeaker terminals on the back
panel. This can be used for listening to an extra set of loudspeakers in
another room.
Please note that care should be taken when selecting if two loudspeakers
are going to be used on each channel. If the combined resistance
measured on the loudspeaker terminals is too low the amplifier may not
switch out of Standby mode until a suitable load resistance is detected.
Note: When using two pairs of speakers, use speakers with a nominal
impedance of between 6-8 ohms each.
Direct
5
This control gives the audio signal a more direct path to the power
amplifier stage of your amplifier, bypassing the bass and treble control
circuits for the purest possible sound quality.

These controls allow subtle adjustments to the tonal balance of the
sound. In the central position these controls have no effect. They only
modify the sound through your loudspeakers and do not affect the
signals sent through the Rec Out connections. With a well-produced
CD and a good system, the tone controls are unnecessary and can
be switched out by the 'Direct' switch. If the musical recording is of
poor quality or other factors are affecting the sound quality, it may be
necessary to adjust the tone controls to compensate.
Infrared sensor
7
Receives IR commands from the supplied Azur remote control. A clear,
unobstructed line of sight between the remote control and the sensor
is required.
Volume
8
Use to increase or decrease the level of the sound from the outputs of
the amplifier. This control affects the level of the loudspeaker output,
the preamp output and the headphone output. It does not affect the
Rec Out connections. It is advisable to turn the Volume control fully anti-
clockwise before switching the amplifier on.
Balance
9
This control allows you to adjust the relative output levels of the left and
right channels. In the central position the output from each channel is
equal. This control only modifies the sound through your loudspeakers
– it does not affect the signals sent through the Rec Out connections.
S1-S5 Source inputs
10
Push the appropriate input selection button to select the source
component that you wish to listen to. The signal selected is also fed to
the Rec Out sockets so that it may be recorded. The input should not be
changed whilst recording.
USB
11
This source input allows connection of a personal computer via USB.
