QSC Audio CM16a Installation- Basics and Mounting, Unpacking, What is Included in the Carton

Section 2: Installation- Basics and Mounting

UNPACKING

There are no special unpacking precautions for the CM16a. However, it is recommended that you keep the original packing material for reuse in the rare event that service be required on the CM16a. If service is required and the original packing material is not available, ensure that the unit is adequately protected for shipment (strong box of appropriate size, sufficient packing material to prevent impact damage or load shifting).

WHAT IS INCLUDED IN THE CARTON

1- CM16a Amplifier Network Monitor

2- AC Power Cord

3- One complete set of the “Phoenix”-type connectors (18 pcs. of 3-pin style, 1 pc. of 5-pin style & 1 pc. of 2-pin style) 4- Hardware manual (this document)

LOCATION CONSIDERATIONS

Where the CM16a is installed is dependent upon the location of audio input sources, amplifiers and network access. The system controller computer should be located someplace convenient for the system operator. In most instances, the system controller computer is remote from the CM16a and the amplifiers . It is preferable to install the CM16a and the amplifiers in the same or adjacent equipment racks; this allows the cabling between them to be standard VGA monitor cables. These cables are generally 2 meters long (6.5 feet). For longer cabling runs, contact QSC’s Technical Services Department at (800) 772-2834 (toll free U.S.A. only) or (714) 957-7150. QSC offers a special cable with individually-shielded twisted-pairs for each audio path; this cable can be used over distances as long as 100 meters (328 feet).

The maximum length of any 10BASE-T Ethernet network segment (cabling between any node and the next node, hub or repeater) is 100 meters (328 feet). The location of hubs and repeaters must be such that this distance limit is not exceeded. If this is impractical or impossible, then use appropriate network transceivers and fiber optic cabling. For larger Ethernet networks, the use of Ethernet routers may be necessary.

MOUNTING THE CM16a

The CM16a is secured to the equipment rack with four screws and washers. Be sure to support the weight of the CM16a when securing to avoid distorting or bending the front panel mounting ears. For mobile, touring or portable applications, support the rear of the CM16a using the rear mounting tabs provided or contact QSC’s Technical Services Department to order rear rack ear extensions. The rear rack ear extension kits add flexibility to you installation options as well as a support-pin option that requires one-time hardware installation at the rear of the rack. For the locating dimensions of the rear support mounting tabs, see the dimensional diagram in the specification section.
