4. Speaker-cable binding posts
On the Hercules II Mono, two sets of
binding posts are provided for the output.
These can be used for standard cabling
(with a two-conductor cable running from
the amp to the speaker) or in a biwired
arrangement with separate cables going
from one amp to the speaker’s woofer
and midrange/tweeter drivers. Consult
your speaker’s manual for more
information. On the Hercules II Stereo,
one set of binding posts is provided for
each channel. These may also be used for
biwiring--see the discussion of the Biwire
switch on page 9.
For Hercules II Mono, connect the marked
connector or cable conductor for the left
speaker cable to the left positive (+ or
red) binding post and the unmarked
connector to the negative (- or black)
binding post underneath. Repeat with the
right speaker cable on the other amp.
Make sure the speaker cables on both
channels are connected identically—
marked cable conductor or connector to
red, unmarked conductor or connector to
black. For Hercules II Stereo, connect the
left cable to the left binding posts and the
right cable to the right binding posts as
described above.

The binding posts accept spade lugs or banana plugs. Make certain that the spade lugs on your cables will fit
the amplifier’s binding posts—do not force the spade lugs onto the posts if they do not fit. Do not use bare
wire connections, because the amplifiers’ high power output might vaporize any stray wires that touch.
The binding posts are designed to be tightened only by hand. Do not use tools to tighten the binding posts.
Before you turn on the power, check at the terminals of the speakers and the amplifier to make sure the
positive and negative leads of the speaker cables are separated and not touching.
