Troubleshooting
No power. First ensure that your active Eris speaker is plugged in. If it's connected to a power con-
ditioner, verify that the power conditioner is turned on and functioning.
No audio. If your active Eris speaker 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 active speaker is working correctly. Also, verify that the volume control is set to
provide enough amplitude for the signal. If only the passive Eris speaker is not passing audio, check your
speaker-wire connections and verify that the bare wire is fully inserted into each connection.
Hum. Usually, hum is caused by a ground loop. Verify that all audio equipment is connected to the same
power source.
Sound is thin. If the sound of the speakers seems thin and brittle, check that your speaker wires are con-
nected correctly (i.e., the positive/red connection on the active Eris speaker is connected to the pos-
itive/red connection on the passive Eris speaker and the negative/black connection on each is connected
to the negative/black connection on the other).
