3. Operation
3.1 Precautions
Please take the following precautions for optimum performance and safety:
1.Before use, your amplifier first must be configured for proper operation, including input and out put wiring hookup. Improper wiring can result in serious operating difficulties and malfunction. For information on wiring and configuration, please consult the Setup section of this manual or, for advanced setup techniques, consult Crown’s Amplifier Application Guide available online at www.crownaudio.com.
2.Use care when making connections, selecting signal sources and controlling the output level. The load you save may be your own!
3.Do not short the ground lead of an output cable to the input signal ground. This may form a ground loop and cause oscillations.
4.Tampering with the circuitry, or making unauthorized circuit changes may be hazardous and invalidates all agency listings.
5.Do not operate the amplifier with the yellow Clip LEDs is on.
6.Do not operate the amplifier with less than the rated load impedance. Due to the amplifier’s output protection, such a configuration may result in pre mature clipping and speaker damage.
WARNING: Never connect the output to a power supply, battery or power main. Electrical shock may result.
Remember: Crown is not liable for damage that results from overdriving other system components.
3.2 Startup Procedure
Use the following procedure when first turning on your amplifier:
1.Turn down the level of your audio source.
2.Turn down the level controls of the amplifier.
3.Turn on the “Power” switch. The Power indicator should glow.
4.Turn up the volume of your audio source to an optimum level.
5.Turn up the volume controls on the amplifier until the desired loudness or power level is achieved. In Bridge mode, only the Channel 1 volume control is functional.
6.Turn down the volume of your audio source to its normal range.
If you ever need to make any wiring or installation changes, don’t forget to disconnect the power cord. For help with determining your system’s optimum gain structure (signal levels) please refer to the Crown Amplifier Application Guide, available online at www.crownaudio.com
3.操作
3.1预防措施
为了获取最佳性能和安全，您应该采取以下的预防措施：
1.使用前，必须针对功放的正常运行进行配置，其中包括输入和输出配线连接。接线不当将 会导致操作失效或设备损坏。有关接线和配置的信息，请参考本手册的安装部分，另外， 要了解高级安装技术，您可以参阅Crown 功放应用指南，您可以通过网址www.crownaudio. com 在线阅读此应用指南。
2.在进行连接、选择信号源和控制输出水平时，需要特别小心。您所节省的能源仍是您自己 的。
3.不要将输出电缆的接地导线与输入信号接地短接。否则会形成接地环路，导致振动。
4.篡改电路或在未经允许的情况下改动电路是很危险的，并导致本产品无法获取保修。
5.当黄色的削波LED指示灯亮起时，不要运行功放。
6.低于额定负载阻抗时，不要运行功放。由于功放输出的保护，这样操作将导致过早达到削 波，可能损坏扬声器。
警告：不要将输出端连接到电源、电池或供电网，否则会导致电击发生。
切记：由于超负荷驱动其它系统组件而导致的设备损坏，Crown 概不负责。
3.2启动步骤
初次启动功放时，请按如下操作步骤进行：
1.调低音源音量。
2.调低功放音量。
3.按下“Power”开关按键。电源指示灯点亮。
4.将音源音量调至最佳水平。
5.调节功放上的音量调节器，直到达到所需响度或功率级别。在桥接模式下，您只能使用通 道1音量调节器。
6.将音源音量调低到正常范围。
如果您需要更改接线或安装，确保先断开设备的电源线。为使您的系统获取最佳增益水平（信号 电平），您可以阅读Crown功放应用指南。如需获取此应用指南，您可以通过访问Crown网站www. crownaudio.com下载。
