IF AT FIRST YOU DON'T SUCCEED

Some suspected defects of the equipment are in fact very often found to have arisen from faulty operation.

Sometimes malfunctioning ancillary equipment which is connected to the A2 unit is to blame. Before you

consult your dealer or contact us, we would like you to check the items on the foilowing list to see whet-

her you can correct the malfunction yourself.

I. NO MUSICAL REPRODUCTION IS POSSIBLE:

a) Headphones are connected, In which case the other outputs are switched off. Remove the headphones

plug.

b) You have selected MONITOR (4). The display (6) shows "MON". Switch off the monitor function.

c) You have selected PROCESSOR (5). The display (6) shows "PROC". Switch off the processor.

d) "Standby" mode unintentionaily switched on via the remote control. Press the button "On".

e) Check whether one of the causes given below under Paragraph 3.is responsible.

If the green LED on the front panel and the display is not iiluminated the fault could be with the mains

fuse. This results mainly from a defect in the power transformer or the amplifier electronics (eg as a

result of a lightning strike). Please consult your dealer.

THE AMPLIFIER SWITCHES OFF DURING OPERATION.

In this case one of the safety circuits (overheating, short circuit, ultrasonic or DC) has functioned. This fault

will be diagnosed by the processor and shown in the display.At the same time you will be requested to switch

off the amplifier with the onloff switch (I).

a) If the word "temp" blinks in the display proceed as follows: switch the EVOLUTION A2 off (on/off switch

(I)) and wait 5 minutes. Providing the amplifier works correctly after this overheating had occurred.

Please check whether the conditions explained in this manual regarding placement and cooling have been

complied with.

b) If the A2 unit switches itself off within a few seconds of being switched on and the word "overload" appe-

ars in the display, a short circuit has occurred in the loudspeaker cabling or in the loudspeaker itself.This

fault must be rectified before the unit can be retaken into use. Before taking the unit into reuse it is to

be switched off with the onloff switch (I) for about I minute.

c) When "dc" is shown in the display it is the result of a direct voltage arising.from a source, possibly defec-

tive, such as a CD player etc which disturbs the functioning of the EVOLUTION A2.

d) Generally these faults can be eliminated by checking that cables of ancillary equipment are properly

connected and that the unit is correctly placed.

3. HUMMING DURING MUSICAL REPRODUCTION.

Ground loop through the aerial amplifier or postal cabling: Check if the humming stops following removal of

the aerial cable from the tuner (and, if connected to the A2, the television and video recorder). If this is succ-

cessful fit a sheath current filter to the aerial cables of these receivers. (Your dealer will supply).

REMOTE CONTROL DOES NOT FUNCTION.

a) The remote control battery is empty.

b) There is no line of sight between the remote control transmitter and the A2 (the transmission of the

signal is by infra-red light).
