safety warnings 

It is important that your equipment is earthed at all times via its own mains lead. Failure to 

do this may be hazardous. The power supply components within the units are designed to be 

operated at lethal voltages and energy levels. Circuit designs that embody these components 

conform with applicable safety requirements. Precautions must be taken to prevent accidental 

contact with power-line potentials. Do not connect grounded test equipment. 

This unit complies with EN 5008 1-1 and IEC 80 1/2 

Caution: 

The  BLU  employs  a  laser  that  emits  both  visible  and  invisible  radiation. 

Removal  of  the  top  cover  or  tampering  with  any  of  the  enclosed  electronics  may  result  in 

exposure  to  hazardous  levels  of  laser  radiation  that  could  cause  eye  damage.  To  prevent 

injury this product should be returned for qualified service to Chord Electronics Ltd. 

There are no user serviceable parts within any Chord Electronics Choral 
product. Unauthorised tampering or dismantling of this product will 
invalidate the warranty and could cause injury 

 

 

mains connection 

The  mains  connector  of  your  Choral  product  is  at  the  back  of  the  unit.  Plug  the  female  end 

(socket)  of  the  mains  cable  into  the  power  connector  of  your  Choral  product,  and  the  male 

end  (plug)  of  the  mains  cable  into  mains  wall  socket  or  mains  extension  socket.  The  mains 

connector type will differ slightly for each Choral product. This is due to the highly 

compact nature of this range requiring differences in chassis metalwork for each product.
