Classe Audio CT-2300 Manuel D’Utilisation

To remove dust from the cabinet of your amplifier, use a feather duster or a lint-

free soft cloth. To remove dirt and fingerprints, we recommend isopropyl alcohol

and a soft cloth. Dampen the cloth with alcohol first and then lightly clean the 

surface of the amplifier with the cloth. Do not use excessive amounts of alcohol 

that might drip off the cloth and into the amplifier.

From time to time, the air intake filter will need to be vacuum cleaned or 

removed and rinsed with clean fresh water. A pressure sensor measures the 

airflow to determine when it is necessary to clean the filter. When cleaning is 

required, the Standby LED will flash (combined red/blue) and a message will 

be sent to connected touchscreen controlled devices via the connected CAN-Bus

system. Since this is a maintenance and not a protection feature, the amplifier 

will continue to operate while the LED is flashing, so as not to interrupt a 

listening session. Once the amplifier enters standby mode it will require reset to 

operate normally (press and hold the standby button). Use this opportunity to 

check and clean the air intake filter. Remove the front panel (CT series amps) or

the air intake cover (Delta series amps) to access the filter.
