Infrared sensor
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
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
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.
CD, Tuner/DAB, BD/DVD, Aux
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
Tape Out sockets so that it may be recorded. The input should not be
changed whilst recording (but the recorded signal can be checked using
the tape input Tape Monitor).
Tape Monitor
This control lets you listen to the output signal from a tape recorder or
signal processor connected to the amplifier's Tape In/Rec Out sockets.
When Tape Monitor is selected, the source component chosen by the
input selection buttons continues to be routed to the Rec Out sockets for
recording or processing.

MP3 Input
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 ‘MP3’) or the front panel 3.5mm stereo-jack input (labelled ‘MP3
In’).
Press the MP3 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
Allows for the connection of headphones with a ¼" jack plug connector.
Headphones with an impedance of between 32 and 600ohms are
recommended. When the headphones are connected, the loudspeaker
relay is released switching off the output to the loudspeakers (speakers A
and B).
Speaker B
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
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.
Bass and Treble
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.
