ADVICE 

 

INSTALLATION PRECAUTIONS and USER INFORMATION 

 
Your new A5

 

CR

 Preamplifier is designed and built to provide trouble-free performance, but as with 

all electronic devices it is necessary to observe a few precautions: 
 
Heed all warnings shown on the back of the product. 
 
Only connect the A5

 

CR

 Preamplifier to a mains outlet having the same voltage as marked at the back 

of the unit. 
 
Always ensure that when disconnecting and reconnecting your audio equipment the mains supply is 
switched off. 
 
Position the mains lead and signal interconnects where they are not likely to be walked on or trapped 
by items placed on them. 
 
Do not use near water, or place water-filled containers on the amplifier, for example, a flower vase 
or potted plants.  

If water does spill inside, immediately pull out the mains plug from the

 

wall 

socket and inform your dealer, who should then check the unit before further use.  Entry of 
liquid into the pre-amplifier is dangerous, and may cause electric shock or fire hazard. 

 
Do not place the unit near direct heat sources such as radiators, direct sunlight or other equipment. 
 
Do not remove any covers or try to gain access to the inside.  There are no internal adjustments or 
fuses you can replace yourself.  Refer all service work to an authorised Musical Fidelity agent. 

 
Note: Unauthorised opening of the equipment will invalidate any warranty claim. 

 
Dust regularly with a soft cloth or soft brush but be careful when using cleaning or polishing agents - 
they may harm the surface finish. 
 
The electronics in modern hi-fi equipment is complex and may, therefore, be adversely affected or 
damaged by lightning. For protection of your audio system during electrical storms, remove the 
mains plugs and disconnect any aerial lead. 
 
If after-sales service is required, to help your dealer identify the A5

 

CR

 Preamplifier please quote the 

serial number located on the rear panel of the unit. 
 
 

RADIO  FREQUENCY  INTERFERENCE  (R.F.I) 

 
This product has been tested to ensure that its operation is not adversely affected by normal 
background levels of R.F.I., and that it does not itself generate excessive amounts of interference. 
However, if a problem persists, please contact your Musical Fidelity agent.
