Operating instructions
Firstly please note that the volume control system used does not go to zero volume a standby button is
provided for when you require the unit to produce no sound.
There are 256 steps to the volume control from a minimum volume of 0 to a maximum volume setting of
255. These are accessed by pressing the volume up and volume down buttons.
The 10 number keys from zero (minimum) to 9 (maximum) provide a range of preset volumes within this
range.
Pressing the mute button will take the amp to an extremely low volume.
The sleep button will switch it to standby. When in standby any active button will restore the amp to
operation. The amp remembers the volume setting that was in use when it went into standby, on restore it
will select either the stored volume or the volume of the key pressed whichever is the lower. On first key
press the volume is deliberately inhibited at 50% of maximum. Subsequent key presses will allow higher
volumes to be selected.
The power will also put the unit into standby although only the power button can be used to switch the unit
back on again.
It is safe to leave the amp in standby as very little current is used in that mode. In standby only the Red
power LED will be illuminated. This is the normal method of switching off the amp.
All the LEDs are configured to fade as the ambient light level drops; this is so that the led brightness does
not look excessive even in a darkened bedroom.
In the event of a power failure the amp will resume operation in the same state (on or standby) and at the
same volume setting when power is restored.
The amp should have been wired via a switched fused mains outlet if you have any reason to suspect the
