BLUETOOTH CONNECTION
  Turn the power switch ON. The speaker will enter pairing mode. Open the Bluetooth 
menu on your device and select “MK402BT”. You will hear two beeps when pairing is 
complete.

AUX CONNECTION
  Plug the included 3.5 mm cable into your device and the AUX IN jack (7).

PLEASE NOTE: for the best sound quality in Bluetooth or AUX mode, we recommend 
that your device's volume level be set no higher than 90%.

ROOM PLACEMENT
  Due to their well-behaved off-axis response and excellent dispersion, your new 
Dayton Audio speakers are less dependent upon placement than most loudspeakers. 
Often, simply placing them where they best fit into the decorating scheme is all that is 
necessary for exceptional performance.

  If you are inclined to perform a more rigorous positioning exercise, the following tips 
will help you achieve all the performance that your system is capable of:

  Carefully select a few recordings with which you are very familiar. Choose high 
quality recordings made with simple microphone placement techniques and with strong 
vocals by a single performer. Horns, strings, vocals, and drums should snap into place 
when the loudspeakers are optimally positioned.

  Start with the speakers directly in front of your primary listening position. Viewed 
from your seat, the angle between the speakers should be 30 to 60 degrees. During the 
design of most Dayton Audio speakers, performance is optimized for a location 10-12 
feet in front of the tweeter. If possible, position your speakers to take advantage of this. 
Avoid hard vertical edges within 3 or 4 feet of either side of the cabinets, and position 
them about 1-2 feet out from the wall.

  Begin with one of the selected recordings, paying close attention to the positions of 
the instruments and vocalist. Adjust the speakers a few inches at a time, returning to 
the listening position to evaluate the results. Once placement is optimized, the vocalist 
will be firmly positioned in front of the instruments and the instruments will seem to be 
between or behind the loudspeakers.

  Pay special attention to the bass. The relation between bass response and room 
position is critical. Tightly localized high and low pressure spots result from reflections 
at the room boundaries. Moving one or both of the loudspeakers just a few inches will 
rearrange thousands of hot and dead spots all over the room. The secret to proper 
positioning is to keep the worst of these spots from falling on the primary listening 
position. Position the speakers so that the bass levels are in proper perspective to the 
rest of the musical spectrum. Listen to several recordings so you can scrutinize the 
bass from a variety of instruments. The most common positioning error involves getting 
the bass level right for one note, but not for others.

  Loudspeaker positioning can be time consuming, but the rewards justify the effort.

CABINET CARE
  The finish of your speakers can be maintained and enhanced by periodic use of a 
surface protector such as “Armor All

®

.” The grills may be vacuumed or gently tapped or 

brushed to remove dust and debris.

CONNECTING YOUR  SPEAKERS
  With the power turned OFF, use the included speaker wire or other high quality 
wire for the connection between the Master and Slave speakers. For distances up to 
10 feet, conventional 18AWG wire is acceptable. For longer runs, heavier wire should 
be used. For proper performance please observe correct polarity. To ensure proper 
polarity, connect the red Master terminal to the red Slave terminal and the black Master 
terminal to the black Slave terminal. Virtually all two-conductor wire is marked in some 
way to help you do this. One side will be marked with a colored stripe, a raised rib, or a 
different colored conductor. Use the marked side for the red (positive +) connections.
