4.2. Troubleshooting
No Power. First ensure that your active Eris E4.5 is plugged
in. If it’s connected to a power conditioner, verify that the
power conditioner is turned on and functioning.
No audio. If your Eris E4.5 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
volume control is set to provide enough amplitude for the signal.
If only the passive E4.5 is not passing audio, check
your speaker-wire connections and verify that the bare
wire is fully inserted into each connection.
