PROTECTIVE GRILLS:
Protective grills are attached to the speakers with a self-centering magnet system. You can remove them by
gently pulling them away from the speakers. They can be re-attached by bringing them near to their position
on the speaker and the magnets will lock the grills into the right position.
Figure 2: Protective grills are attached to the speakers with a self-centering magnet system.
FEET:
Firmly mount the feet into the black aluminum sockets in the bottom of the speaker. Feet are height
adjustable and allow levelling of the speaker in the case of uneven floors.

4. PLACEMENT
All loudspeakers interact with the environment in which they are placed. Loudspeaker performance is
influenced by the size, shape, and contents of the listening room as well as the placement of the loudspeaker
within the room. The distance between the speakers and the rear wall should, ideally, be between a half and
a full meter. (For the best stereo imaging and a sense of spaciousness, place the speakers at equal distances
from the primary listening position and the side walls; move speakers closer to the corners or walls of the
listening room to increase bass response).
Remove all obstructions between speakers and the primary listening position. For instance, a coffee table
between a speaker and the primary listening position will degrade stereo imaging and timbre. Placing a
speaker near large objects may also cause unwanted reflections.
In home theatre systems, the magnetic radiation of the loudspeakers must be taken into consideration. It is
strongly advised to refrain from placing front loudspeakers closer than 50cm from your TV. The distance
between the speakers should be slightly less than the distance from the speakers to the listening area. For the
best stereo imaging and sound staging, the listener should be equidistant from the 2 speakers. The angle at
which the speakers are aimed at the listener will vary from room to room. We recommend the following two
alternatives:
1) Position the speakers parallel to the rear wall (widen the soundstage).
2) Toe the speakers in to aim at the listening area (optimal stereo imaging and timbre).
Experimentation is vitally important to achieve optimum results in any given environment.
5. CONNECTIONS
Turn off all audio system power before making any connections. Use high-quality loudspeaker cables. The
length and type of speaker cable used for your system will have an audible effect. Make all connections
observing the proper polarity, positive-to-positive (+) and negative-to-negative (–). Most speaker cables are
marked so that it is possible to distinguish between conductors by the color of the insulation or by a white
stripe or small raised edge along one conductor. Correct phasing of the speakers is vital for sound quality.
Connecting your Gracioso loudspeakers
1. Connect one pair of loudspeaker wires to the input connectors. Then connect the same pair of
loudspeaker wires to the desired power amplifier output channel.
2. Repeat step 1 to connect the second loudspeaker to a separate power amplifier output channel.

6. USING





After the correct installation and connection of the speakers, first check the settings of your audio
amplifier/receiver.
Never use unprotected/uninsulated jumpers/bridges for connecting the +/+ or -/- connectors, as this
may cause a short circuit.
Never insert metallic or conductive objects in connectors for cables.
Before use, always check if specification of audio amplifier/receiver meets the requirements of the
loudspeakers (Power, Impedance, Voltage etc.).
Make sure that audio amplifier/receiver is initially set to minimum volume and gradually increase to
desired volume.







New loudspeakers should NEVER be exposed to high volume initially, since electronic and mechanical
components must burn-in gradually.
Never exceed the listening volume which could cause uncomfortable feeling or ear damage.
Never exceed the listening volume which would cause excessive vibrations or distorted sound through
the speakers.
Always disconnect loudspeakers cable on the AMPLIFIER side first, as it may otherwise cause a short
circuit on amplifier outputs.
Before disconnecting cables always turn off the receiver/amplifier or disconnect it from the electricity.
Listening should be a pleasure, so always use the volume settings that will suit you.
