4.2 Troubleshooting 故障排除
没有电源。首先确保你的R系列演播室监听器已经插上电源。如果它连接到电源调节器上，确认电源调节器
已经打开并正常工作。如果问题仍然存在，从演播室监听器上断开电源线，检查后面板上的保险丝。
保险丝外壳位于IEC电源线连接处的正下方。熔断的保险丝内部可能是黑色的，或者里面的电线可能出现断
裂。一个非常黑的保险丝是一个迹象，表明可能有东西短路了。尝试用一个新的保险丝替换。R65 V2和
R80 V2在使用100-120伏电源基础设施的地区使用两个T2AL保险丝，在运行220-240伏电源基础设施的地
区使用T1AL保险丝。如果你需要更换保险丝，请谨慎地使用适合你所在地区的正确保险丝。
没有音频。如果你的R系列演播室监听器看起来是通电了，但在播放音源的音频时却没有听到声音（灯亮
了，但家里没人），首先要确保连接音源和监听器的电缆是正常的。另外，确认输入增益控制的设置为信
号提供足够的振幅。
嗡嗡声。通常情况下，嗡嗡声是由接地回路引起的。确认所有的音频设备都连接到同一个电源上。如果你
没有使用电源调节器，我们强烈建议你添加一个。这不仅有助于减少嗡嗡声，还能更好地保护你的设备免
受电源浪涌、断电等影响。
尽可能地使用平衡电缆。如果你的音频设备不提供平衡输出，你可以把它连接到一个直接盒上，这将提供
一个接地升降开关和一个平衡输出。最后，确保你的音频线不靠近电源线，也不接近电源线。
最后，确保你的音频电缆不靠近电源线，并使用适合你的应用的电缆长度。使用太长的电缆不仅会增加噪
音的风险，而且会增加电缆盘绕的可能性，这基本上会形成一个天线，接收各种音频干扰。
NoPower.Firstensurethatyour R-Series studiomonitor is plugged in.If
it's connected to a power conditioner, verify that the power conditioner
is turned onand functioning.Ifproblemstill exists,disconnectthe power
cable from your studio monitor and check the fuse on the back panel.
The fuse housing is located directly beneath the IEC power cable connection.
A blown fuse may look black on the inside or the wire inside might appear
broken.Averyblackfuseisasignthatsomethingmayhaveshortedout.Try

need to replacea fuse,be cautious to use the correct fuse foryour region.
No audio. If your R-Series studio monitor appears to power on but you
hearnosoundwhenplayingaudiofromyouraudiosource(thelightsare
on but nobody's home), first make sure that the cable connecting your
audio source to the monitor is working correctly. Also, verify that the
Input Gain control is set to provide enough amplitude for the signal.
Hum.Usually,hum is causedby agroundloop.Verifythat all audioequipmentis
connected to the same power source.If you arenot using a powerconditioner,
we highly recommend that you add one. Not only will this help to minimize
hum, it will better protect your equipment from power surges,brownouts,etc.
Use balanced cables whenever possible. If your audio device does not offer
a balanced output, you can connect it to a direct box,which will provide a
ground-lift switch and a balanced output. Finally, make sure that your audio
cablesarenotrunnearpowercables,and usecablesthataretheappropriate
length foryour application. Using cables that aretoo long not only increases
theriskofnoise,itincreasesthelikelihoodthatthecablesarecoiled,whichwill
essentially createan antenna that picks up all kinds of audio interference.
