Operation Manual

操作手册

H.  AC Power Inlet

Connects to 100V~120V or 220V~240V, 

50Hz/60Hz AC power supply.

I.  Power Voltage Switch 

Select the power supply voltage to be 100V~120V 

or 220V~240V.

Warning: 

Do not switch the voltage when 

the CXM2000 is connecting to the power 

supply! Setting wrong voltage will damage it. 

J.   USB Connector

 

Connects for firmware update only.

Warning: 

User must not connect to any 

equipment via this USB connector, or the 

CXM2000 or any connected equipment may 

be damaged. 

K.  8-way DIP Switches

Switches 1~4 are for JBL cinema speaker selec-

tion. Switch 5 is for fault detection. Switch 6 is 

for 5.1 or 7.1 channel installation system selec-

tion. Switches 7 and 8 are for monitor and fault 

detection functions of subwoofer 1 and 2.

Warning: 

Before setting the 8-way DIP 

switches, the installation system must be 

correctly wired and the DIP switches must 

be set according to the configuration matrix 

provided in “Appendix II. 8-way DIP Switch 

Configuration” on page 19, or damage 

may occur. 

L.  HD15 Output/Input Connectors

Connects the HD-15 connectors to the Crown 

DSi series or XLC series amplifiers through VGA 

cables. This allows the CXM2000 to send and 

receive signals from the amplifiers for fault detec-

tion and monitor function. 

L-Bi-amp:

 Connects to the amplifier of left 

channel (bi-amp speaker) or left and right chan-

nels (passive speaker).

R-Bi-amp:

 Connects to the amplifier of right 

channel (bi-amp speaker) or no amplifier (pas-

sive speaker).

C:

 Connects to the amplifier of center channel.

SW1:

 Connects to the amplifier of low frequency 

effect channel (subwoofer 1). 

SW2:

 Connects to the amplifier of low frequency 

effect channel (subwoofer 2).

Ls/Rs:

Connects to the amplifier of left surround 

& right surround channels.

Bsl/Bsr:

 Connects to the amplifier of back sur-

round left & back surround right channels.

Warning: 

The output connection must 

match to the DIP switches configuration.

Please see “Appendix I. Pin Definition” on page 

18 to select the correct interface converter for 

the XLR connector.

M. HD25 Input Connector

Connects the HD-25 connector to the main 

outputs of the cinema processor. 

N.  RS-232 Connector

Connects the RS-232 connector to the Theater 

Management System (TMS)  for sending fault 

detection results. Please see “Appendix V. 

Control ASCII Protocol” and “Appendix VI. Com-

munication Settings” on page 20 for detailed 

communication protocol.

Warning: 

The connection must use dedi-

cated serial cable.

H..交流电源接口

接入100V至120V或220V至240V,50Hz 
/60Hz的交流电源。

I..电源电压切换开关.

选择正确的供电电压:100V至120V或
220V至240V。

注意:

务必选择正确的供电电压!

通电状态下切勿切换开关!否则会
损坏设备。

J..USB接口

只限固件升级连接用。

注意:

用户不可以擅自使用该USB

接口连接其他设备,否则会损坏
CXM2000或任何连接的设备。 

K..8路DIP开关

1至4号为JBL影院扬声器选择开关,第5
号为故障检测开关,第6号为安装系统
5.1或7.1声道选择开关,第7和8号为次
低音扬声器1和2的监听和故障检测功能
选择开关。

注意:

在设置对应的DIP开关前,

请务必确定系统连接是正确的,避
免不当的设备连接导致任何的损
坏。请依据第19页的“附录二、8
路DIP开关设置”进行相应的系统
设置。

L..15针输出/输入接口

15针接口通过VGA线缆连接Crown DSi或
XLC系列功放,供CXM2000输出优化后的
音频信号,并接收来自功放的监听信号
和故障检测信号。

L-Bi-amp 接口:双功放驱动时连接左
声道的功放,或被动式时连接左右声道
的功放。
R-Bi-amp 接口:双功放驱动时连接右
声道的功放,或被动式时不连接功放。
C 接口:连接中置声道的功放。
SW1接口:连接次低频声道的功放(次低
音扬声器1)。
SW2接口:连接次低频声道的功放 (次
低音扬声器2)。
Ls/Rs接口:连接左右环绕声道的功
放。 
Bsl/Bsr接口:连接左右后环绕声道的
功放。

注意:

声道功放的连接务必与DIP开

关设置匹配。

若连接至XLR接口的功放,请参看第
18页的“附录一、引脚定义”使用合
适的转换接口。

M..25针输入接口

25针接口用于连接影院处理器作为声
源输入。 

N..RS-232接口
