NoPower.
FirstensurethatyourErisXTstudiomonitorispluggedin.If
it’s connected to a power conditioner,verify that the power
conditioner is turned on and functioning. If problem still exists,
disconnect the 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. A very black fuse is a sign that something
may have shorted out. Try replacing the fuse with a new one. The
E5XT uses a T1L fuse. The Eris E7XT and E8XT use a T2L fuse. If
the fuse blows again, you will need to contact PreSonus for a repair.
No audio.
If your Eris XT studio monitor appears to power on but you
hear no sound when playing audio from your audio source (the lights
are 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,humiscausedbyagroundloop.Verifythatallaudio
equipmentis connected to the same power source. If you are not
using a power conditioner, 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 cables are not run near power cables, and use cables
that are the appropriate length for your application. Using cables that
are too long not only increases the risk of noise, it increases the
likelihood that the cables are coiled, which will essentially create an
antenna that picks up all kinds of audio interference.
没有电源。首先确保你的
Eris XT
演播室监听器已经插上电源。如果它连接到一个电源调节器上，请确认电源调节器已
经打开并正常工作。如果问题仍然存在，从你的演播室监视器上断开电源线，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看起来是黑色的，或者内部的电线可能出现断
裂。保险丝非常黑是一个迹象，表明可能有什么东西短路了。试着用一个新的保险丝来替换。
E5XT
使用一个
T1L
保险
丝。
Eris E7XT
和
E8XT
使用的是
T2L
保险丝。如果保险丝再次熔断，你将需要联系
PreSonus
进行维修。
没有音频。如果你的
Eris XT
演播室监听器似乎开机了，但当你从音源播放音频时，你没有听到任何声音（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。这不仅有助于最大限度地减少嗡嗡声，而且可以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，确保你的音频电缆不靠近电源线，并使用适合你的应用的长度的电缆。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。
