Setup
The nuBox A-125 are high-quality, very neutral active stereo loud-
speakers. They impress with an extremely homogeneous, precise,
and „direct“ sound reproduction with the finest resolution in the
entire frequency spectrum. However, even „honest loudspeakers“
are exposed to the manifold influences of room acoustics. In order
to achieve the most natural and true-to-life reproduction possible,
please observe the following general installation instructions:
• The rear-facing bass reflex ports should be at least 3 centimetres
away from back- and side walls in order to avoid air flow noise.
Some distance to the back- and side walls also helps prevent an
increase in the bass- and fundamental ranges.
• When placed on a shelf, the best sound is achieved when the front
edge of the speaker is either flush with the shelf or even protrudes
slightly. This allows the loudspeaker to radiate the sound freely into
the room and helps to avoid voices sounding like coming through
a funnel.
• Within horizontal listening angles up to 30 degrees off the hori-
zontal axis, you will experience no significant change or loss in
sound quality. Only at wider listening angles does the sound lose
its brightness slightly. It is then advisable to point the speakers
towards the listening position.
• The most natural sound is achieved when the tweeters are ap-
proximately at ear level. But even 20 degrees above or below
the tweeter axis, the sound is still homogeneous. If your active
speakers need to be placed lower or higher, they should ideally
be angled so that the tweeters are aimed at the listening position.
Connections
Caution! All connections to the A-125 must be made before you
connect the loudspeaker to the mains!
The right speaker is the so-called master. All source devices are
connected here. The connection to the left loudspeaker (the slave)
is made with the supplied loudspeaker cable with four-pin round
plug connectors.
1.
Connect the loudspeaker cable
First connect the two speakers to each other. A suitable loudspeaker
cable with round plugs is included in the scope of delivery. Longer
speaker cables can be purchased as accessories at www.nubert.de
Please note:
Pay attention to the orientation of the connectors in the sockets.
a) The groove on the connector must point to the left.
b) Push the clamping nut forward and fasten it tightly clockwise to
prevent the connector from falling out.
2.
Connect the signal cables
Now connect all source devices and (optional) subwoofer to the
master loudspeaker. See illustration on page 7 for details.
3.
Connect the power cable
First connect the power cable to the power jack on the back of the
master speaker and then to the mains.
The wiring of your speakers is now complete!
