Speaker Connections
The 4 pin connector plugs allows easy connection of two speakers for single ended connec-
tion or one speaker for bridged connection.
1.
Use 12AWG (max) 2-conductor stranded speaker wire for speaker connection plugs.
2.
Strip approximately 1/4 to 1/2 of an inch off the ends and twist the strands together so
there are no loose ends that can cause shorts.
3.
On the amplifier rear panel, insert one end of each striped speaker wires into the provid-
ed plugs and tighten the screws. Ensure that all speaker wires are firmly attached to the
plugs.
4.
Match the polarity markings on the rear panel of the amplifier unit with the polarity of the
speakers. If the wiring is incorrect then the peakers will be out-of-phase, with a noticable
decrease of in the bass frequencies and and sound performance.
5.
Connect the speaker wires to the appro and - terminals on the speakers. Confirm
connection and polarity.
For single ended speaker connection (Figure 3) the speaker impedance sholud be 4 ohm or
8 ohm.
For bridges speaker connection (Figure 4) the speaker impedance sholud be 8 ohm.

NOTE: If the Speaker Out senses a short, the amplifier will enter protect mode and ‘Fault’ will
appear in the amplifier web page and app. In “Fault” mode, the audio amp will be shut
down, but the logic and control will remain on.
To reset the amp, power cycle the amplifier: unplug the amplifier from the wall jack
for minimum 30 seconds and then plug it back in. If the amp does not return to normal
operation, please contact ELAC at 714.252.8843 or at [email protected].
