Champ-One can be mounted in a 19” rack, taking up only 2 rack spaces. Always allow a good
airflow around the amplifier’s front, rear, side, top and bottom. When installing in a rack with
multiple audio devices, it is advisable to leave one rack space between units. Fill the empty rack
spaces with meshed blind panels for improved ventilation. Never mount the amplifier in a sealed
cabinet, unless adequate forced ventilation is provided. The amplifier may not be able to meet the
specifications when installed in a poorly ventilated environment. Support the unit at the rear when
installing in a rack !
Always remember: excessive heat is one of your amplifier’s biggest enemies !
4. Rack mounting and wiring
When wiring an audio rack, it is a good installation practice to route all AC wiring
along one side of the rack and all audio wiring along the other side to avoid coupling
mains cable interference into the audio path. Please use only high quality signal
and speaker cables and connectors. Pay special attention to avoiding ground loops
when installing audio devices in metal racks, use special insulating rack mounting
hardware, such as the so called ‘humfrees’. This mounting hardware will make sure
that several devices mounted in a rack will be electrically isolated from the rack, and
thus are a great help in avoiding ground loops. Any damage caused by user induced
ground loops are not covered by warranty ! Ground loops can cause hum or other
strange side effects that will affect stable and safe operation of audio hardware and
peripheral devices. Ground loops are often created by connecting tuners to cable
distribution sockets. Use a RF isolating transformer whenever there is a cable signal
tuner or digital TV tuner in the audio path !
