QUICK SETUP GUIDE
We recommend the following procedure when unpacking the speaker:
4.
Without removing the internal packaging
end-cap, gently rotate the carton so the open
end rests on the floor and the bottom of the
carton is facing you.
5.
Gently lift the carton allowing the speaker and
protective end-cap to slide out of the carton
and remain on the floor.
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.
1.
Remove the outer shipping carton.
2.
Place the inner carton on the floor with
the top facing upwards.
3.
Open the top of the box.

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.
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.
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.
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.
