MAGNETIC FIELD

CAUTION! Do not locate sensitive high-gain equipment such as preamplifiers directly above or below the

unit. Because this amplifier has a high power density, it has a strong magnetic field which can induce hum

into unshielded devices that are located nearby. The field is strongest just above and below the unit.

If an equipment rack is used, we recommend locating the amplifier(s) in the bottom of the rack and the
preamplifi er or other sensitive equipment at the top.

磁场

警告！不要把敏感的高增益设备，如前置放大器或大型录音机直接放在其上或者旗
下，因为此功放具有大功率密度，形成强磁场，这种磁场会使靠近的未屏蔽的设备
产生嘈杂声。扩音器的上部和下部磁场最强。

如果使用设备架，我们建议把功放放在架的底部，把前置放大器或者其他敏感设备
放在架顶。

FCC COMPLIANCE NOTICE

This device complies with part 15 of the FCC rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept
any interference received, including interference that may cause undesired operation.

CAUTION: Changes or modifications not expressly approved by the party responsible for compli­ance could void the user’s authority to operate the equipment.

NOTE: This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates,
uses, and can radiate radio frequency energy and, if not installed and used in accordance with
the instruction manual, may cause harmful interference to radio communications. However, there
is no guarantee that interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which can be determined by turning
the equipment off and on, the user is encouraged to try to correct the interference by one or more
of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

• Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.

• Consult the dealer or an experienced radio/TV technician for help.

2.2 安装功放

NOTE: Before you begin, make sure your amplifier is disconnected from the power source, with
the power switch in the “off” position and all level controls turned completely down (counter­clockwise).

Use a standard 19-inch (48.3 cm) equipment rack. See Figure 2.2 for amplifier dimensions. You may also stack amplifiers
without using a cabinet.

NOTE: Amplifiers should be supported at both the front and rear of the rack.

2.3 Ensuring Proper Cooling

When using an equipment rack, mount units directly on top of each other. Close any open spaces in rack with blank panels.
Do not block front or rear air vents. The back of the rack should be open.

Figure 2.3 illustrates standard amplifier airflow.

Operation Manual

注意：开始安装前，确保您已断开功放与电源的连接，将功放电源开关设置到关闭位
置，并将所有音量调节到最低（逆时针旋转）。

使用一个标准的19寸（ 48.3厘米）设备机架。具体功放尺寸请参见图2.2。您还可以直接将功放
安放到平台上，而不用将功放安装到机柜。

注：机架前后均应该支撑功率放大器。

2.3 保证正常散热

在使用设备机架时，直接将设备安装在机架上。使用空白面板将所有开放的空间封闭。不要阻挡
前面和后面的通风口。机架的后面应该保持开放。

2.4 Wiring to the CXM2000 Monitor and Crossover System

It is recommended to use the XLC Series amplifiers with the Crown CXM2000 Monitor and Crossover System. Figure 2.4
and figure 2.5 are the samples of wiring XLC amplifiers to the CXM2000 in bi-amplified cinema speakers system and
passive cinema speakers system through cables. This allows the CXM2000 to send the audio signals to and receive signals
from the XLC amplifiers for crossover, fault detection and monitor functions. More details about the wiring, please read the
Operation Manual of the CXM2000 Monitor and Crossover System.

Please see figure 2.6 for the HD-15 pin definition.

2.4 连接至CXM2000扬声器优化/监听系统

建议将XLC系列功放搭配Crown CXM2000扬声器优化/监听系统使用。图2.4和图2.5的示例，分
别为在双功放通道驱动式扬声器系统和被动式扬声器系统中，通过线缆连接功放的15针接口至
CXM2000。连接成功后，CXM2000可以输出优化后的音频信号，并接收来自XLC功放的监听信号和
故障检测信号，实现分频、监听和故障检测功能。更多详细的连接信息，请看CXM2000扬声器优
化/监听系统的操作手册。

关于15针接口的引脚定义，请看图2.6。

2.5 Alternative: Choosing Phoenix Connectors as Input Connectors

Besides connecting the XLC amplifiers to the CXM2000 through HD-15 connector, you can also connect to other input
devices through the phoenix connectors on its rear panel. Crown recommends using pre-built or professionally wired
balanced line (two-conductor plus shield), 22-24 gauge cables and connectors (see Figure 2.7). Unbalanced lines may be
used, but may result in hum or RF noise over long cable runs.

NOTE: Custom wiring should only be performed by qualified personnel.

2.5 可选：选择凤凰头作为输入接口

除用HD-15接口连接XLC功放至CXM2000外，还可以选择后面板的凤凰头接口连接其他输入设
备。Crown建议您采用已有的或专业的平衡线（双导线带屏蔽），22-24线规的电缆和接口连接
凤凰插头（见图2.7）。您也可以使用非平衡线，但是，如果使用的电缆较长，会产生噪音或射
频干扰。

注意：必须由专业人员进行接线操作。

2.6 Choosing Output Wiring and Connectors

Crown recommends using pre-built or professionally wired, high-quality, two-conductor, heavy gauge speaker wire and
spade lug connectors or bare wire for your output connectors (Figure 2.8). To prevent the possibility of short-circuits, wrap
or otherwise insulate exposed loudspeaker cable connectors.

Non-Touch cover provides protection of electric shock from the output terminals. Remove it to connect the cables to the
output terminals and reinstall it when finish. To reinstall it, insert tab A into the slot right beside the output terminals (see
figure 2.9). Put the screw through tab B and screw it into the hole left beside the output terminals (see figure 2.9).

Below are the suggested guidelines to select the appropriate size of wire based on the distance from amplifier to speaker.

Distance Wire Size

up to 25 ft. 16 AWG

26-40 ft. 14 AWG

41-60 ft. 12 AWG

CAUTION: Never use shielded cable for output wiring.

NOTE: Custom wiring should only be performed by qualified personnel. Class 2 output wiring is required.

Distance Wire Size

61-100 ft. 10 AWG

101-150 ft. 8 AWG

151-250 ft. 6 AWG

Operation Manual

2.6 选择输出连接线和接口

在连接输出至扬声器时，Crown建议您采用已有或专业的，高质量的，双绞线的，大规格扬声器
线材及铲型接线片端口，或裸线（见图2.8）。为了防止短路，您需要包住或使用其他方法绝缘
外露的扬声器电缆接头。

防触摸保护壳用于对输出接口提供防电击保护。接线前需卸下保护壳，再连接线缆到输出接口；
在接线完成后，需装回保护壳。安装防触摸保护壳时，将页片A插入输出接口右侧的插槽内（见
图2.9），将螺丝穿过页片B，拧紧螺丝将其固定在输出接口右侧的小孔内（见图2.9）。

建议使用下表的指南，根据扩音器与喇叭的距离选择合适的音箱。

距离 尺寸

25英尺以下 16 AWG

26-40英尺 14 AWG

41-60英尺 12 AWG

警告：不要使用屏蔽电缆作为输出连接线！
注：定制接线只能由合格的人员执行。要求使用第 2 类输出接线。
