3. Rack mounting and wiring Champ-4 can be mounted in a 19” rack, taking up only 1 rack space. 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 compulsory 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.
4. Stand alone use It is possible to integrate Champ-4 in a high quality audio chain. In order to adapt the front panel dimensions to the dimensions of other equipment, it is possible to remove the 19” brackets and handles for an even more sleek and refined look. Remove the two screws marked in red circles and slide off the handles. 9 INFO@APART-AUDIO.
