UNPACKING

There are no special unpacking precautions for the CM16a. 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, adequately protect 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 prefer-

able to install the CM16a and the amplifiers in the same or adjacent equipment racks; this allows the cabling between them to be standard 15 pin 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 loca-

tion 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

fibber optic cabling. For larger Ethernet networks, the use of Ethernet routers may be necessary.

MOUNTING THE CM16A

Note- Rack mounting is optional.

The CM16a is secured to the front of 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 Ser-

vices 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 sup-

port mounting tabs, see the dimensional diagram in the specification section.

The illustration shows the basic mounting technique. Support the CM16a from under-

neath while positioning the mounting holes in the desired location in the rack. Secure

with standard rack hardware. The CM16a uses fan-drawn air for cooling. The air intake is

on the left side of the chassis and the exhaust vents are on the front panel. Be certain not

to obstruct these openings! Allow ample “open space” around them in order to maintain

unobstructed air flow.

Note! The CM16a’s recommended ambient operating temperature is

0°C. to 50°C. (32°F. to 122°F.). Do not install the CM16a in environments

that expose it to temperatures outside this range. Some equipment

rack environments can get hot. If there is any question, measure the

air temperature inside the equipment rack and supply additional cool-

ing (air flow) to keep the ambient temperature within the specified

limits. QSC amplifiers use back-to-front air flow and therefore do not

exhaust hot air into the rack.

CONNECTING AC POWER

The CM16a uses a detachable IEC standard power cord for connecting to a grounded AC

source. To connect power to the CM16a: identify the proper end of the cord, match the ori-

entation of the receptacle on the rear panel and insert firmly into the receptacle. The

power supply will accept from 100 to 240 Volts AC, 47 to 440 Hertz, without any changes.

The power cord used must be suitable for the line voltage the CM16a is connected to. If a

different type of IEC power cord is required (different style of plug on the outlet end) con-

tact QSC’s Technical Services Department to obtain the correct cord assembly.

Do not connect the CM16a to power sources outside the specified

ranges of voltage or frequency! Damage to the unit could result or the

user could be exposed to unsafe operating conditions.
