Indiana Line Nota 550X Loudspeakers Pair

Product Information

The Indiana Line loudspeakers are designed to provide high performance and meet the musical quality precision, dynamic range, and power handling capability required by advanced recording techniques. The loudspeakers come in different models, including NOTA 240 X, NOTA 250 X, NOTA 260 X, and NOTA 550 X, which are all two-way bass-reflex systems. NOTA 550 X is a three-way bass- reflex system. The loudspeakers have different impedance levels, frequency ranges, crossover frequencies, dimensions, and weights. The NOTA system has rubber feet to prevent slipping and comes with adhesive pads.

Product Usage Instructions

  1. Read the instructions carefully before installing the loudspeakers to obtain the best performance.
  2. Match the loudspeakers with a hi-fi stereo or Home Cinemasystem to recreate live concerts or movie soundtracks.
  3. Place the loudspeakers at least a couple of meters apart and at an equal distance from the listening area’s center.
  4. Link the loudspeakers using good quality cables with a proportionate cable cross-section to the length.
  5. Check that the load impedance is not lower than the amplifier can accept and keep the polarities correct.
  6. Ensure that no stray strands of wire are shorting speaker outputs together and that the loudspeaker terminals are tight.
  7. Move the loudspeakers around the room to find the position that provides the best performance and rotate them to find the best acoustics. Small changes can make significant acoustic differences.
  8. The sound of all loudspeakers improves over time, and optimal performance is obtained after several tens of hours of listening.

The Indiana Line loudspeakers are been devel-oped to warrant high performances as to meet the musical quality precision, dynamic range and power handling capability required by the most advanced recording techniques.
These speakers, matched with a hi-fi stereo or Home Cinema system, allow to recreate in your listening room the enrapturing emotion of a live concert or the atmosphere of a movie sound track.
The right distance between the two speakers have to be not closer than a couple of meters. The ideal listening area is at the centre of the speaker systems, at an equal distance from the boxes.

POSITIONING

Do not place the speakers near to heat sources and away from dust or moisture.
Positioning speakers, please remember that the acoustical characteristics of the room play an important role in the sound quality:

  • a room with not much furniture and/or with large windows increases the high frequencies;
  • a room with a lot of furniture and/or carpets and curtains decreases the high frequencies;
  • placing the speakers close to a wall or a corner the level of low frequencies is increased;
  • placing the speakers in a recess the frequency response can be changed; if this location cannot be avoid, put the front panels of the speakers outside the recess.

RUBBER FEET

We suggest to apply on the bottom of the box the supplied adhesive pads.

LINKING

  • All connections should be made with the amplifier switched off.
  • Check that the load impedance is not lower than the amplifier can accept.
  • Link the speakers by using good quality cables; the cable cross section have to be proportionate to the length: 1,5 square millimeters up to three metres; 2,5 millimeters for greater lengths.Indiana-Line-Nota-550X-Loudspeakers-Pair-FIG 4

Keep the polarities: in the event of wrong phase (opposite polarity) the performances of the au-dio system can be reduced. Usually the positive is marked with the red color and/or the “+” sign, the negative with the black and/or the “-” sign.Indiana-Line-Nota-550X-Loudspeakers-Pair-FIG

Ensure that no stray strands of wire are shorting speaker outputs together. Check that the loudspeaker terminals are tight.

FINE TUNING

Before fine tuning, please check that all the connections are correct and the polarities too. Follow the instruction manual of your ampli-fier to adjust the speaker levels and/or fur-ther controls. To locate the position supplying the best performances, try to move the speakers inside your listening room, even small differences can supply important acoustical changes. As well, try to rotate the speakers to find the right acoustical position.
Sound of all loudspeakers improves with the time: the better performances can be matched just after several hours of listening.

FOAM PLUG

To rightly match the sound of Nota 240, 250, 260 and 740 with the acoustics of your room, it is possible to change the bass frequencies level, simply fitting the supplied foam plug into the reflex vent: usually
when the speaker is placed inside a recess.
