OPERATING PRECAUTIONS

• In outdoor use, avoid positioning the speaker in places that are directly exposed to harsh weather.
• Do not use solvents, alcohol, benzene, or other volatile substances to clean the external parts of the speaker.
CHARACTERISTICS
• "Spotlight" speakers that can be flush-mounted in false ceilings like normal halogen spotlights used in lighting sys-
tems.
• Body in plastic (ABS) with metal front grille.
• Available in three colours: chrome (HS 1026C), gold (HS 1026 G), and white (HS 1026W).
• Good acoustic features.
• Transformer that enables connection with constant voltage lines at 70 V and 100 V.
• Possibility to select the sound power to be delivered from various values.
• Can be coupled with a subwoofer to improve low frequency reproduction.
• Quick and easy installation thanks to the spring hooks and the standard dimensions of the mounting hole.
• Connection by means of screw terminals.
• Extremely compact dimensions.
• Excellent design.
INSTALLATION
CAUTION
• Speaker installation must only be carried out by qualified personnel in full respect for the safety standards.
• Speaker installation must be secure. Check to make sure that the support surface (e.g. panel, false ceiling, etc.) has
the necessary mechanical characteristics to support the weight of the speaker without the danger of it falling and
causing damage to persons or structures.
1) Make a hole of diameter 92 mm in the false ceiling at the point selected for speaker installation.
2) Rotate the two spring hooks toward the rear part of the speaker and insert them in the hole made, as shown in Fig-
ure 1 on page 17.
3) Push the speaker at point "A" (Fig. 1) to insert it partially into the hole, as shown in Figure 2 on page 17.
4) Push the speaker at point "B" (Fig. 2) to insert it completely into the hole, securing it in the false ceiling as shown in
Figure 3 on page 18.
5) Make the electrical connections as described in the section below.
CONNECTIONS
CAUTION
• For connecting the speaker, use only qualified and experienced personnel having sufficient technical knowledge or
specific instructions for making the connections correctly and thus preventing any electrical dangers.
• To prevent the risk of electrical shock, do not make the speaker connections with the amplifier switched on.
• Before putting the speaker into operation, re-check that all the connections have been made correctly to ensure
that there are no accidental short circuits which could give rise to dangerous electrical sparks.
• The entire sound system must be designed and installed in compliance with the current standards and regula-
tions regarding electrical systems.
NOTES
• To prevent inductive phenomena from causing hum or disturbance which could jeopardize efficient system operation,
the line that supplies the speaker should not be run together with electrical energy conductors, microphone cables, or
low level signal lines coming from amplifiers.
• To minimize the inductive effects (hum) due to coupling with surrounding electrical fields, twist together the two con-
ductors that supply the speaker.
• In connections with bipolar cables, use the type which has markings to distinguish the polarity (e.g. insulation of a dif-
ferent colour, different coloured wires, etc.).
The HS 1026 series speakers are designed for connecting to constant voltage audio lines at 70 V or 100 V. Connection
to the audio line is made using the "M" terminal strip of the speaker (Fig. 4, page 18).
When making speaker connections, keep the following indications in mind:
• The output voltage of the amplifier must correspond to the input voltage of the speaker.
• The sum of the nominal power values of all the speakers connected to the audio line must not exceed the power of
the amplifier.
• The connection should be made "in phase"; i.e. where the polarity of the amplifier output corresponds with the
polarity of the speaker input.
