12. Volume Fade in and Out
Volume fading is involved in the following cases:
1) Listening Mode Change
2) Input Source Change
3) Return From Test Tone
During fading of the volume, the display is blinking and the controller does not accept any
command from the remote control. When the blinking stops, the user can control the system using
remote control again.
13. Digital Error Detection
The system provides two digital inputs; optical and coaxial. The coaxial input should be used
with a true 75 ohm RCA interconnect cable. When one (or two) digital inputs are not connected,
or connected inappropriately (for example the source unit is not powered on) the system can
detect this situation. When pushing the input button on the remote control unit, the selected input
source is displayed for about 7 sec. If digital data is properly received, the display will change from
blinking to non-blinking after about 2 sec. due to the volume fading. If the digital data reception is
not error-free, it remains blinking. When this situation occurs, connections or the digital output of
the headunit should be checked. Note that the system does not provide error detection or zero-bit
input detection on its analog input, such as line input1 and line input2.
14. Amplifi er Shutdown and Message Display
The system can detect the following error modes of the amplifi er:
1) Short Circuit and Over Current
2) Under Voltage
3) Over Temperature
When the system is in an under-voltage situation (2) (less than 9.5V) the overall system is shut
down. The system will not give any message for under voltage situation. When the system is fi rst
put into protection for situations (1) or (3) it will self-test for 10 milliseconds. (While the system is
self-testing, the sound may be discontinued.) If the same situation is detected after a cetain time is
elapsed, the system causes the amplifi er to shut down by disconnecting the amplifi er section from
the power supply, and will display „AMP PROTECT“ on the OSD for about 110 sec (~2 minutes).
In this situation, no command can be executed. After the stated time has elapsed, the system
automatically recovers to normal operation with the volume level two steps down from the level
prior to shutoff.
