AUDIO CONNECTIONS
PLACEMENT
1. Attach the four supplied pads to the
bottom of each speaker to protect the
finish of the speaker.
2. Position each speaker in a vertical
orientation with the tweeter on the top.
3. Angle the speakers so the high-frequency
transducer in each speaker is aimed directly
towards your ear.

4. The speakers should be placed so
the listening position and the two
speakers form an equilateral
triangle. Adjusting the distance
between the speakers will affect the
quality of bass heard at the listening
position. Experiment with speaker
positions to find the placement that
produces the preferred bass
response and stereo image.
POWER CONNECTIONS
1. Confirm the power switch is in the OFF position.
2. Connect the supplied power cord to the power
receptacle on the rear of the speaker.
3. Connect the power cord to an available power outlet.
Note:
The 3 Series MKII speakers incorporate a universal power supply allowing them
to be used worldwide. The ground terminal of the IEC plug is required by wiring
codes and regulations and must always be connected to the electrical installation
safety ground.
B Balanced ¼" TRS
1. Connect professional equipment with balanced outputs to the XLR or
¼" TRS input of the speaker using balanced signal cables. Connect
consumer equipment with unbalanced outputs to the ¼" TRS input of
the speaker using unbalanced signal cables.
2. Set the INPUT SENSITIVITY switch to the -10dBv setting for most
applications. Set the switch to the +4 dBu setting:
- When connecting 3 Series MKII speakers to professional equipment with
a +4 dBu nominal output level. To determine the nominal output level of
the connected equipment, consult the documentation supplied with the
connected equipment.
- If you notice the sound is distorted, or you find it is too loud, set this
switch to the +4 dBu setting.
MAKING SOUND
1. After connections are made, reduce the output level of the audio source
(Mixing Console, Computer Recording System, or Preamp) to minimum.
2. Set the 3 Series MKII POWER SWITCH to the “ON position.” After a delay of
7 seconds, when the POWER INDICATOR on the front of each speaker
illuminates, the speakers are ready to reproduce audio signals.
3. Power on connected audio equipment. Slowly advance the volume control
of connected audio equipment to achieve a suitable listening level.

5. DO NOT use this apparatus near water.
8. DO NOT install near any heat sources such as radiators, heat registers, stoves, or other
apparatus (including amplifiers) that produce heat.
9. DO NOT defeat the safety purpose of the polarized or grounding type plug. A polarized
plug has two blades with one wider than the other. A grounding type plug has two
blades and a third grounding prong. The wider blade or the third prong are provided for
your safety. If the provided plug does not fit into your outlet, consult an electrician for
replacement of the obsolete outlet.
10. PROTECT the power cord from being walked on or pinched, particularly at plugs,
convenience receptacles, and the point where they exit from the apparatus.
11. ONLY USE attachments/accessories specified by the manufacturer.
12.
USE ONLY with a cart, stand, tripod, bracket, or table specified by the
manufacturer, or sold with the apparatus. When a cart is used, use caution
when moving the cart/apparatus combination to avoid injury from tip-over.
13. UNPLUG this apparatus during lightning storms or when unused for long periods of time.
14. REFER all servicing to qualified service personnel. Servicing is required when the
apparatus has been damaged in any way, such as power-supply cord or plug is
damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus
has been exposed to rain or moisture, does not operate normally, or has been dropped.
15. DO NOT expose this apparatus to dripping or splashing and ensure that no objects filled
with liquids, such as vases, are placed on the apparatus.

cord plug from the AC receptacle.
17. Where the mains plug or an appliance coupler is used as the disconnect device, the
disconnect device shall remain readily operable.
18. DO NOT overload wall outlets or extension cords beyond their rated capacity as this can
cause electric shock or fire.
The exclamation point, within an equilateral triangle, is intended to alert the user
to the presence of important operating and maintenance (servicing) instructions
in the literature accompanying the product.
The lightning flash with arrowhead symbol within an equilateral triangle is
intended to alert the user to the presence of uninsulated “dangerous voltage”
within the product’s enclosure that may be of sufficient magnitude to constitute
a risk of electrical shock to persons.
ESD Warning: The icon to the left indicates text regarding potential danger
associated with the discharge of static electricity from an outside source (such
as human hands) into an integrated circuit, often resulting in damage to the
circuit.
WARNING: To reduce the risk of fire or electrical shock, do not expose this apparatus to rain
or moisture.
WARNING: No naked flame sources – such as lighted candles – should be placed on the
product.
WARNING: Equipment shall be connected to a MAINS socket outlet with a protective
earthing connection.
CAUTION: To reduce the risk of electric shock, grounding of the center pin of this plug must
be maintained.
WARNING: This product is intended to be operated ONLY from the voltages listed on the
back panel or the recommended, or included, power supply of the product. Operation from
other voltages other than those indicated may cause irreversible damage to the product and
void the products warranty. The use of AC Plug Adapters is cautioned because it can allow
