Front panel controls

Standby/On

Switches the unit between Standby mode (indicated by dim power LED)
and On (indicated by bright power LED). Standby is an eco power mode
where the power consumption is less than one watt. The unit is designed
so that it can be left safely in Standby mode when not in use. 

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). 

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.

Protection

LED flashes to indicate activation of CAP5 protection system. Refer to the
CAP5 section of this manual for more information.

Speaker LEDs

Indicator shows the speaker terminals that are selected. The speaker
terminals selected are changed with the remote control.

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 the Pre-Out sockets,
and do not affect the signals sent through the Tape 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.

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  pre-
amp output and the headphone output. It does not affect the Tape 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
and the Pre-Out sockets – it does not affect the signals sent through the
Tape Out connections.

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.

Note:

Whilst plugging a device into the front panel automatically selects

the MP3 input, any other input can still be selected once this has been
done. As a result you may, if desired, leave a device permanently plugged
into the front panel.

CD, Tuner/DAB, 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.
