6. Amplifiers

9. The Linear Range

It is wise before listening to your Linear Centre to make one final check of 
the cables and connections. If all appears well begin listening at a relatively 
low level to confirm that the system is operating as expected. Only increase 
the volume if you are happy that the sound at low levels is fundamentally as 
expected. If you are unhappy, turn the system off and re-check all the cables 
and connections.

Linear Centre may take a little time to “run-in”, and similarly the system will 
also perhaps take some time to reach normal operating temperatures. It is 
unwise therefore to make rapid judgements about the performance of the 
speaker. Your ears too will take some time to adjust to the new sound, so 
revisiting the system set-up, speaker positioning especially, is best left for a 
few days.

Acoustic Energy reserves the right to modify 
product specifications.

The Linear Centre is a relatively high sensitivity speaker that does not require 
a generously rated power amplifier for adequate volume levels to be achieved 
in an average listening room. A minimum of 25 and maximum of 175 
Watts into 8 Ohms per channel is recommended. Linear Centre also offers 
a relatively easy load to the amplifier and does not make unusually heavy 
demands on its power delivery. 

No overload protection systems are fitted to the Linear Centre so it is possible 
to cause damage through over-driving. Such damage can occur whatever 
the power rating of the amplifier and is not covered by any warranty. If ever 
the sound at high volumes becomes distorted your Linear Centre is at risk of 
damage. In such circumstances the volume must be reduced.
