General Information

Attaching feet

If the C55 is not mounted in a rack it will need feet so air can flow in through the bottom panel. Do not place the C55 in a cabinet that limits the airflow through the amplifier. Feet and screws are included in the box. Using long screws can damage the amplifier, please use the screws included in this package.

Rack Mounting

When mounting the C55 in a rack it is important that the airflow through the amplifier is unrestricted. Please leave sufficient space above and below unused to ensure this. You should also avoid mounting any heat generating products underneath the C55. The faceplate is 7mm thick. You need a rack screw with length of at least 16mm.

The C55 comes with adjustable rear rack mounts. To use the rear mounts you need an extra set of cage nuts that you slide into the track in the rear rack mounts. Rear rack mounts should be attached to the rear handle of the C55.

Changing Fuse

The C55 has a main fuse as well as a separate fuse for each channel.

The main fuse holder is located on the rear panel close to the mains input. It is a bayonet mount fuse holder. Use a flat head screw-driver to open the fuse holder by pushing it in and rotate counter clockwise. Do not use force!

The channel fuse holder is located on the relay board inside the amplifier and should only be replaced by authorized service technicians.
