Classe Audio CA-3200 ユーザーズマニュアル

In general, you should refer any service problems to your Classé dealer. Before 
contacting your dealer, however, please check to see if the problem is listed here.

•  The amplifier is not plugged into the AC mains, or the AC 

mains are down (circuit breaker, fuse).

•  A brown-out or short-term loss of power might require the 

internal microprocessor to be reset. Unplug the unit for at least 
30 seconds and then plug it in again and try powering it up.

•  The AC mains fuse is blown. See Troubleshooting #4, below (or 

contact your Classé dealer).

•  The AC mains  is out of range. Check the voltage specified on 

the rear panel.

•  Your protection circuitry may have been engaged. To reset the 

amplifier, press and hold the Standby button for 3 seconds 
to power down the amplifier. Then disconnect all inputs and 
outputs.

•  Then try powering up the amplifier by pressing the Standby 

button. If the LED continues to blink, there is a fault condition 
in the amplifier itself. It should be powered down, disconnected 
from the AC mains and taken to your Classe dealer for service.

•  If it powers up without any difficulty, power it back down and 

reconnect only the inputs. Then restart the amplifier. If it goes 
into its blinking protection mode, something is wrong with a 
component “upstream” of the amplifier—probably a DC offset 
or similar problem. Your amplifier is trying to protect your 
loudspeakers (even small amounts of DC can damage woofers in 
relatively little time). Try different source components to discover 
whether the problem is limited to a single source, or exists all the 
time (which would indicate a problem with the preamplifier). 
Contact your dealer for help with the appropriate component.

•  Make sure you are providing adequate ventilation to the 

amplifier, and that the ambient room temperature is below 
105°F (40°C).

•  Run through the troubleshooting sequence outlined above 

(assuming the amplifier is going into its protection mode).
