Option 3:
Connecting to a system in a bi-amplify scheme.
Like the bi-wire scheme described above, a bi-amplified wiring scheme does
reduce the amount of EMF on the speaker’s high frequency circuitry. However,
in a bi-amplified wiring scheme, the user provides separate amplification for
both sections (high frequencies and low frequencies) of the speaker.
Some audiophiles tend to prefer this method of connectivity as it ensures that
the more “power hungry” woofers are not limited by the additional power
demands of the high frequency portion of the speaker while still maintaining
the EMF benefits of a bi-wire scheme.
NOTE: In a bi-amplify scheme, it is necessary to use matching amplifiers
for both high frequency and low frequency connections, otherwise an
imbalance will occur between each portion of the speaker. This imbalance
will negatively impact performance. Also, using the “A +B” terminals on
a receiver does not offer an improved connection over using a single
speaker wire from the “A” terminals. Separate amplifier channels are
required to receive the benefits of bi-amplification.
1. Turn off all system components and unplug the receiver/pre-amp
and amplifiers.
. Connect a Y-adapter to the corresponding pre-amp output on your
processor.
3. Connect the two amplifier channels you intend to use, one to each
of the two outputs the Y-adapter has created.
. Loosen the corresponding binding posts on the power amplifier you
plan to use for the high frequency portion of your Outlaw Bookshelf
Loudspeakers.
5. Insert the appropriate polarity wire through the postholes on the
amplifier’s binding post.
6. Carefully tighten the binding post until snug. Over tightening will
strip the binding post and prevent a solid connection.
7. Repeat steps 3-6 for the power amplifier you intend to use to drive the
low frequency portion of your Outlaw Bookshelf Loudspeakers.
8. Loosen both sets of the Outlaw Loudspeaker’s binding posts.
9. Remove both binding post jumpers.
CAUTION: Failure to remove these jumpers using this connec-
tion scheme will result in damage to your power amplifier and
or speakers.
10. Connect your “high frequency” amplifier to the high frequency binding
posts on your Outlaw Loudspeaker by inserting the appropriate
polarity wires through the postholes on the binding post.
11. Carefully tighten the binding posts until snug. Over tightening will
strip the binding post and prevent a solid connection.
1. Repeat steps 10-11 for the low frequency portion of your Outlaw
Loudspeakers.
NOTE: Remember that polarity must be maintained between speaker
and amplifier, ie. positive terminal (red post) on speaker to positive
terminal on power amplifier.
CAUTION: Check terminal posts on both connections (speaker and ampli-
fier) to ensure that loose copper strands have not been allowed to “short”
the binding post pairs. Any loose strands that touch both the positive and
negative terminal posts must be removed before powering up the amplifier.
Failure to do so may result in damage to the amplifier or speaker.
