The following guidelines are provided to ensure your safety: When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack. If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack. Operations Guide ­ DOC. 8183 Professional Balanced Audio Receiver: CNX-PBAR4 · 5 R- Professional Balanced Audio Receiver Crestron CNX-PBAR4 NOTE: If rack mounting is not required, rubber feet are provided for tabletop mounting or stacking. NOTE: Reliable earth grounding of rack-mounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (e. g. , use of power strips). Two "ears" are provided with the unit and must be installed so that it can be rack mounted. Refer to the following illustration and complete the procedures below to attach ears to the unit. 2. Using a Phillips screwdriver, remove the three side screws closest to the front panel. Position a rack ear so that its mounting holes align with the vacated holes, and secure the ear to the unit with the three longer screws supplied with the ears. Repeat the procedure to attach the remaining ear to the opposite side. 3. CAUTION: If rack ears are subsequently removed to accommodate a non-rack configuration, be certain to reinstall the shorter screws removed in Step 1. Failure to do so can cause damage to internal components. 6 · Professional Balanced Audio Receiver: CNX-PBAR4 Operations Guide ­ DOC. 8183 Crestron CNX-PBAR4 Hookup Professional Balanced Audio Receiver The CNX-PBAR4 provides great flexibility in redistributing audio signals throughout an entire home.
