ADDITIONAL FUNCTIONS

DISPLAY
The backlit LCD display is designed to show the amplifier's status.
The selected INPUT is displayed across the middle in large letters.
When Volume level is changed, number 0 – 70 will replace INPUT for a few seconds.
A loudspeaker symbol will be present at the top left when in use.
When headphones are plugged in the loudspeaker symbol will change to a headphone symbol.
Mute will change the colour of the symbol to RED, plus X.
Next to the loudspeaker symbol is a number, which represents the volume setting.
EQ and Treble and Bass settings are shown in the top right corner when higher or lower than 0dB.
Where possible digital input sample-rate and connection status will be displayed across the bottom.
CONTROL SETTINGS
When the input or other settings are changed, the last action is memorised, after a short delay. So, when the
amplifier is powered-OFF or goes into Standby the last setting will be remembered when the amplifier is powered –
ON again.

PROTECTION MECHANISMS

The amplifier will protect itself from three types of potential problems, as follows.
OVER TEMPERATURE
The 4040 A's modern high-tech circuitry is designed to run much cooler than conventional amplifiers with similar
power output capability. However, if the amplifier does overheat it will automatically mute the loudspeaker output.
The output will return automatically when the temperature drops sufficiently. To prevent overheating do not run the
amplifier at high levels with restricted airflow or in a place where the ambient temperature is higher than 25C, or 77F.
OVER-CURRENT
If you connect the 4040 A to a loudspeaker load less than 4 Ohms at high levels, or the output terminals, or speaker
cables, are accidentally short-circuited, the 4040 A will immediately protect itself by muting the output. To avoid this
happening, do not connect speaker cables with the amplifier powered and amplifying a signal. If the load is too low
and the level too high, reduce the volume to a lower level. Once the fault has been cleared the amplifier will operate
normally again. If that does not work, power the amplifier off and check the speaker wiring for short circuits.
DC OFFSET
Direct Current (DC) voltage has the potential to damage a loudspeaker if not removed quickly. The 4040 A's DC Offset
protection circuitry will prevent this happening and mute the output.
