VOLUME CONTROL DEFAULT SETTING
The default setting for the user interface control is the 'volume' setting. This will
be displayed on line one of the LCD display as a numeric dB value.
Note: dB values are a professional indication of the amplitude of an audio
signal with full or maximum output achieved normally at 0dB. You will notice
the LCD display on this amplifi er will read minus dB fi gures up until zero which
will indicate maximum output.
The rotary control (10) can be turned both clockwise and anticlockwise to alter
the dB signal. There are 64 steps in total which range from -78.75dB for nil
volume, to 0dB which will provide maximum output.
We have also provided a bar graph display on line 2 of the LCD display, which
indicates the status of the volume control when rotated. There are 16 squares
(
) which run from left to right and will change pro-rata to the increase or
decrease in volume
This display will replace the input music source description on line 2 of the LCD
display while the volume control is operated. This bar graph display will remain
for a period of approx 5 seconds following the end of this volume change and
will then return to indicate the input music source as the default following this
time.
BASS CONTROL
This amplifi er is fi tted with a bass control which offers +/-14dB attenuation
around the centre bass frequency of 100Hz, and +/-3dB across the frequency
range of 45Hz to 259Hz.
To alter this bass control press the function button once, this will change the
LCD display for bass control.
The last setting for the bass will be displayed.
To change the bass setting turn the rotary control (10) either clockwise or
anticlockwise to increase or decrease the bass content.
There are 7 steps around the centre position for +/- attenuation, adjust this
control to your desired listening level.
Attention: Please note that due to the level of boost available on this bass
control, that prolonged use of this amplifi er at high levels with an increased
bass content may cause permanent damage to your speakers. Please operate
this system within the safe working limits of any ancillary equipment that is
connected to it.
Note: following this operation, the LCD display will return to indicate the default
volume setting if no operation occurs within 5 seconds. To reactivate bass
control it will be necessary to press the function button again.
