ConneCtion
WARNING! Turn your amplifier
off before making or breaking any
signal connections!
These speakers are designed with easy-to-use push-
style binding posts that accept bare wire.
Helos 12: Assign the same color to the (+) and
(–) terminals on both the speaker and the amplifier.
Make certain that all connections are tight (figure 1).
Helos 22 Stereo: Connect two sets of speaker
cables from the left and right channels of your
amplifier (figure 2).
Helos 22 Mono: Connect one sets of speaker
cables to one set of binding posts on the Helos 22
and use matching cable to bridge the second set
of binding posts (figure 3).
Use an amp that approximately matches the
speaker’s specified power handling.
To avoid damage, turn down the volume if
the speaker is distorting, sounds harsh, or the
bass begins to break up.
Tone controls and equalizers may increase
the likelihood of distortion, especially at high
volumes. Use these setting sparingly.
