Attaching feet

If the C55 is not mounted in a rack it will

need feet so air can ﬂow in through the bot-

tom panel. Do not place the C55 in a cabinet

that limits the airﬂow throught the ampliﬁer.

Feet and screws are included in the box.

Using long screws can damage the ampli-

ﬁer, please use the screws included in this

package.

Rack Mounting

When mounting the C55 in a rack it is im-

portant that the airﬂow through the amplifer

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 shuld be attached to the rear handle

of the C55.

Changing Fuse

The C55 has a main fuse as well as a sepa-

rate 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.
