plug usually has a "GND" marker molded on it so you can keep
polarity straight after unplugging and replugging. In standard
practice, the GND side connects to the black terminal of the
speaker.
To connect wires to the terminals if you are not using a
banana plug:
1. Strip about 1/2" (15 mm) of insulation from the ends
of each wire. If the wire is stranded, twist the strands together
at the end.
2. Turn the red and black terminal caps counter-clockwise until
they reach their limit. As you do, the hole through the terminal
post will be exposed.
3. Insert the wires into the holes, observing proper polarity.
4. Tighten the terminal caps so that they hold the wire firmly.
Make sure no insulation is caught inside the terminal, to avoid
a loose connection.
2.2 POWER AND PROTECTION
Alesis recognizes that professional speakers need to be strong to
survive, so the Monitor One is designed to handle twice the power
of other near-field monitors. This was achieved by using
proprietary high power drivers and oversized crossover
components, choices made principally to offer the user an
extended margin of safety. Therefore, an amplifier with a
100 watt power rating into 4 ohms, like the Alesis RA-100™
Reference Amplifier, is recommend for most monitoring situations.
Higher or lower power amplifiers may be used, depending on the
size of the listening room and the engineer's preference for normal
working levels.
Be sure to verify that your amplifier is rated for 4 ohm speakers.
Some older amplifiers are not and may fail if overloaded. Alesis is
not responsible for any failures caused by the use of an
inproperly-rated amplifier.
Also, there is no situation where an amplifier rated beyond 200
watts should ever be used because of the danger of damaging the
Monitor One. To do so is asking for trouble and will void your
warranty. On the other hand, if you use too small of a power
amplifier, it is possible to damage the Monitor One if you run it into
heavy clipping and distortion in an effort to get sufficient volume.
This can lead to failures of both the amplifier and the speaker, as
