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.
