C ¨ WARNING ¨ While QSC has endeavored to develop and produce the most dependable and robust `network' audio product for your use, due to the myriad of network situations and equipment that may be encountered in its implementation, QSC cannot be held responsible for network conflicts and associated consequences that may result. For this reason, QSC strongly recommends that the network used for implementation of QSControl products be completely separate from all other networks, data or otherwise. As such, should you elect to integrate QSControl products with your existing network system, all risks attendant to such integration of QSControl products with your existing network or network systems are assumed by you. While QSC strives to provide the highest quality technical solutions for networked audio products, in no event will QSC or its suppliers be held liable for any damages, consequential, incidental or otherwise, including any claims for lost profits and/or savings resulting from any attempted integration of QSControl products with your networking systems.

Please review the following important safety information before operating the CM16a. Explanation of Graphical Symbols The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to humans. The exclamation point within an equilateral triangle is intended to alert the users to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product. SAFEGUARDS Electrical energy can perform many useful functions. This unit has been engineered and manufactured to assure your personal safety. Improper use can result in potential electrical shock or fire hazards. In order not to defeat the safeguards, observe the following instructions for its installation, use and servicing. CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN CAUTION: To reduce the risk of electric shock, do not remove the cover. No user-serviceable parts inside. Refer servicing to qualified service personnel. WARNING: To prevent fire or electric shock, do not expose this equipment to rain or moisture. 1- Maximum operating ambient temperature is 50°C (122°F). 2- Never restrict airflow through the device fan or vents. Please insure that the air intake and exhaust vents are unobstructed. Federal Communications Commission (FCC) Information NOTE: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a commercial installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case the user will be required to correct the interference at his or her own expense. 3- When installing equipment into rack, distribute the units evenly. Otherwise, hazardous conditions could be created by an uneven weight distribution. 4- Connect the unit only to a properly rated supply circuit. The CM16a is suitable for connection to 100 - 240 VAC, 47 - 440 hertz, with no special considerations other than the appropriate IEC power cord. 5- Reliable Earthing (Grounding) of rack-mounted equipment should be maintained. 4 Section 1: Introduction- Overview The QSC CM16a Amplifier Network Monitor provides powerful amplifier management and zone paging capability in a QSControl networked audio system using Ethernet networking technology to communicate with the host computer/ system controller. The DataPort connections are made with QSC DataPort cables (HD-15 male-to-male). These cables are the same type that are used on personal computer systems to connect the monitor to the computer. This allows you to use commonly available cabling for interconnecting amplifiers to the CM16a. Each DataPort connection supports the control and monitoring functions for two audio channels. When using The host computer uses the QSControl application software to operate the networked audio system, including the CM16a's and their amplifiers. The software operates on the Microsoft Windows NT® version 4.0 operating system and can be customized using Microsoft® Visual Basic Professional Edition. The CM16a is a control and monitoring device that relies on software to do its job. The functions and capabilities provided in the design of the CM16a can only be realized with This manual outlines the capabilities of the CM16a as well as its installation and connections. The operation of the CM16a is accomplished using QSC's QSControl software. Note that not all hardware features may be supported by the current software revision. Please refer to the software's documentation & help file for information regarding software features, usage and functions. proper software implementation. Keep in mind that this manual's intent is to outline these capabilities and provide a reference for properly installing and interconnecting the CM16a to the networked system's host computer, the audio inputs and the amplifiers to be controlled and monitored. A thorough knowledge of the control software's features and operation will provide the best possible results for the end user. Each CM16a performs control and monitoring functions for up to 16 amplifier channels. This could be up to eight 2-channel or four 4-channel amplifiers (or some combination of these) at the time this document was printed. The amplifiers supported by the CM16a are the PowerLight, PL2, PL2A, DCA, and CX series of QSC amplifiers that have a built-in Data Port. Models that do not have a built-in DataPort or models that have a DP1 option or "V2" DataPort (such as the EX, MXa, & ISA From all of us at QSC Audio Products, thank you for your purchase. the CM16a with amplifiers that have more than two channels (such as the 4 channel cinema amplifiers) additional DataPort connections are required. Note: PL2A amplfiers have programmable filters and crossovers. This makes gain "reporting" to the host unreliable as the frequency content relates directly to reported output levels. Since the output level is used to calculate gain, it is not possible to gaurantee accurate gain reporting when the PL2A is set for any of its various frequency boost/ cut/crossover modes. series) are NOT supported by the CM16a. 5 Section 1: Introduction- Physical Characteristics & Layout PHYSICAL CHARACTERISTICS The CM16a is one rack space high (1RU) and has an internal, univeral 100-240V AC power supply.
