•  Reorient the receiving aerial (or antenna) or 

route the antenna cable of the receiver as far as 

possible from the unit and its cabling.

•  Ensure that the receiver uses well-screened 

antenna cable.

•  Relocate the receiver with respect to the unit.

•  Connect the receiver and this product to 

different AC outlets.

•  If the problem persists contact your dealer.

Drive units move when the C51 is 
switched on or off

This is normal as the amplifier electronics 
settle.

The sound from one or more speakers 
is either muffled (lacking in HF) or 
thin (lacking in bass)

Check that the crossover cards have been 
correctly inserted, and in particular that the 

type of crossover card in each bay matches 
the type of loudspeaker connected to the 
corresponding output channel. Each crossover 
card includes indicator lights that show 
the presence of power and, by their colour 
combination, indicate the type of speaker for 
which the card is designed. Confirm that these 
are indicating correctly.

Unit stays in standby

This generally indicates a problem with the 
trigger connection and/or setup:

•  Check the trigger cabling and that it is correctly 

wired.

•  Ensure that the source device providing the 

trigger is configured to provide a voltage in the 

range 5–30v ac or dc when the unit is required 

to come out of standby and for the trigger 

voltage to be removed when the unit is to enter 

standby.
