and associated consequences that may result. For this reason, QSC

strongly recommends that the network used for implementa-

tion of QSControl products be completed 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

EXPLANATION OF GRAPHICAL

SYMBOLS

The lightning flash with arrowhead sym-

bol, within an equilateral triangle, is in-

tended 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 equi-

lateral triangle is intended to alert the

users to the presence of important op-

erating and maintenance (servicing) in-

structions in the literature accompany-

ing the product.

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.

Section 1: Introduction- Overview

The QSC CM16a Amplifier Network Monitor provides powerful

amplifiermanagementandzonepaging capabilityin aQSControl

networked audio system using Ethernet networking technology

to communicate with the host computer/system controller.

FromallofusatQSCAudioProducts,thankyouforyourpurchase.

The host computer uses the QSControl application software to

operatethe networkedaudio system,includingthe CM16a’sand

their amplifiers. The software operates on the Microsoft Win-

dows NT® version 4.0 operating system and can be customized

usingMicrosoft®VisualBasicProfessionalEdition. Thenetwork

may theoretically have hundreds of CM16a’s but the real-world

limitation is determined by the network bandwidth, type and

configuration.

This manual is intended to be a reference for installing and

connectingtheCM16aaswellasoutliningthehardwarecapabili-

ties of the CM16a. The actual operation of the CM16a is depen-

dant upon the instructions received from the control software.

Note that not all hardware features may be supported by the

current software revision. Please refer to the software’s docu-

mentation or help file for information regarding software fea-

tures, usage and functions.

The CM16a performs control and monitoring functions for QSC

amplifiers equipped with a DataPort. This could be up to eight 2-

channel or four 4-channel amplifiers (or some combination of

these). The amplifiers that are supported by the CM16a are the

PowerLight,PL2, DCA, andCXseries ofQSCamplifiers thathave

a built-in Data Port. Models that do not have a built-in DataPort

or models that have a DP-1 option (such as the EX and MXa

series) are NOT supported by the CM16a.

TheDataPort connectionsare madewithordinary VGAcomputer

monitor-type 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

CM16a with amplifiers that have more than two channels (such

as the 4 channel cinema amplifiers) additional DataPort connec-

tions are required.

The CM16a is not a “plug-and-play” replacement for the CM16.

TheCM16ahasamuchimprovedfeature-setandheighthasbeen

reduced from 2RU to 1RU. Additionally, connectors are slightly

differentbetween thetwo. Weight hasbeen reducedfrom 22 to

11 pounds.

A final note; 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

propersoftwareimplementation.Keepinmindthatthismanual’s

intent is to outline these capabilities and provide a reference for

properly installing and interconnecting the CM16a to the net-

worked system’s host computer, the audio inputs and the ampli-

fierstobecontrolledandmonitored.Athoroughknowledgeofthe

control software’s features and operation will provide the best

possible results for the end user.

Note: In this manual, bold type (e.g.

PORT A)

within the para-

graph text indicates a control or connection that is labeled

similarly on the CM16a.

Section 1: Introduction- Physical Characteristics & Layout

PHYSICAL CHARACTERISTICS

Each CM16a is one rack space in height (1RU) and has an internal AC power supply. Its chassis depth is 37.7 cm (14.84 in.). The width of

the chassis is 44.0 cm (17.32 in.). For the detailed mounting dimensions, please see specification section. The weight of the CM16a is

approximately 5 kilograms (11 pounds).

FRONT PANEL (numbers correspond to reference locations shown in illustration to right)

The front panel of the CM16a includes:

1- AC OFF / POWER switch

2- Cooling air exhaust vents (intake vents on left side of chassis as viewed from the front)

3- AC POWER indicator LED

4- DIAGNOSTIC indicator LED

5- Network status indicator LED’s ( RCV, XMT and LINK STATUS), duplicated on rear panel for convenience

6- PORT A through PORT H connection indicator LED’s

7- Access hole for the BYPASS switch (

this is not labeled on the panel

)

REAR PANEL (numbers correspond to reference locations shown in illustration to right)

The rear panel of the CM16a has duplicates of the RCV, XMT and LINK STATUS indicator LED’s so that network status can be detected

from the rear of the unit when installed in the equipment rack. The rear panel provides the following connections:

8- Eight HD-15 receptacles (PORT A through PORT H) for connection to amplifiers with VGA-type cables

9- Sixteen “Phoenix”-type (Euro-style) 3-pin receptacles for audio inputs (PORT A CH 1 through PORT H CH 16)

10- One “Phoenix”-type 5-pin receptacle for audio monitoring functions (MONITOR CHAIN,IN and OUT)

11- One “Phoenix”-type 3-pin receptacle for paging audio signal input (PAGE)

12- One “Phoenix”-type 2-pin receptacle for remote sensing (example: detecting a switch closure or logic event; RLY / TRG IN)

13- One “Phoenix”-type 3-pin receptacle for access to SPDT relay contacts (used for remote switching of external devices; RLY OUT)

14- One RJ-45 type receptacle (10BASE-T Ethernet computer network connection)

15- One DB-9 type receptacle (RS-232 Port for network and firmware utilities)

16- IEC-type detachable AC power cord receptacle (for connection to AC power line) with integral fuse holder
