-
There are numerous mechanical and electrical factors to be considered when installing a professional audio system (in addition to those which are strictly acoustic, such as sound pressure, angles of coverage, frequency response, etc.).
-
Hearing loss. Exposure to high sound levels can cause permanent hearing loss. The acoustic pressure level that leads to hearing loss is different from person to person and depends on the duration of exposure. To prevent potentially dangerous exposure to high levels of acoustic pressure, anyone who is exposed to these levels should use adequate protection devices. When a transducer capable of producing high sound levels is being used, it is, therefore, necessary to wear ear plugs or protective earphones. See the manual technical specifications to know the maximum sound pressure level.

DESCRIPTION
Q 15, Q 15-L, Q 15-P – TWO-WAY POINT SOURCE MODULES
Q 15 speakers are two-way, bi-amp point source modules for mid-distance and
long throw applications, merging a compact size with very high output and
accurate voice and sound reproduction. The systems are equipped with the
latest generation of RCF precision transducers: a 15″ neodymium woofer (4.0″
v.c.) and a 1.4″ exit compression driver (4.0″ v.c.) providing a 1500 W power
rating. Directivity, horizontal 22.5° and vertical 60° (Q 15), 90° (Q 15-L),
and 40° (Q 15-P) make Q 15 speakers ideal to be used in point source
configuration for mid-distance applications or clustered with narrower angles
for long throw applications. The enclosure shape is trapezoidal and offers a
22.5° coupling angle on each side. Thanks to two different fly bars, it can be
clustered both horizontally (up to 4 modules with the same fly bar) and
vertically (up to 6 modules with one flybar and up to 8 modules with two fly
bars). Connections to the amplifier are made through Speakon multi-pole
connectors. The grille is in custom perforated steel epoxy coated, with woven
fabric backing. The cabinet is made of multi-ply Baltic birch plywood and
finished in a very resistant polyurea black paint.
CONNECTIONS
THE REAR PANEL
The rear panel displays 2 sockets, both for ‘Neutrik Speakon NL4’ (4-pole)
plugs:
- The INPUT socket receives the signal from the amplifier
- The LINK socket can be used to link another speaker
‘BI-AMP’ MODE
The speaker must be powered by two amplifiers (one for the low frequency, one
for the high frequency) and an external crossover is required.
Check in the specification table the impedance of both ways, their power, and
the suggested crossover frequency.
CONNECTIONS
- Low-frequency amplifier + output to the pin 1+ of the SPEAKON connector
- Low-frequency amplifier – output to pin 1- of the SPEAKON connector
- High-frequency amplifier + output to the pin 2+ of the SPEAKON connector
- High-frequency amplifier – output to pin 2- of the SPEAKON connector
WARNING! CAUTION! Loudspeaker connections should be only made by
qualified and experienced personnel having the technical know-how or enough
specific instructions (to ensure that connections are made correctly) in order
to prevent any electrical danger.
To prevent any risk of electric shock, do not connect loudspeakers when the
amplifier is switched on.
Before turning the system on, check all connections and make sure there are no
accidental short circuits.
The entire sound system shall be designed and installed in compliance with the
current local laws and regulations regarding electrical systems.
NOTES ABOUT LOW IMPEDANCE CONNECTIONS
WARNING! CAUTION!
- The total loudspeaker impedance must not be lower than the amplifier output impedance. Note: a loudspeaker total impedance equal to the amplifier output one permits to get the maximum deliverable power (but a higher loudspeaker impedance entails less power).
- The total loudspeaker power shall be adequate for the maximum deliverable power of the amplifier.
- The loudspeaker line shall be short (for long distances, it may be necessary to use cables with large cross-section wires).
- Always use cables having wires with an adequate cross-section, considering the cable length and the total loudspeaker power.
- Loudspeaker lines must be kept separated from the main cables, microphone cables, or others, in order to avoid inductive phenomena that may cause hum or noises.
- Use loudspeaker cables with twisted wires to reduce hum caused by inductive effects due to coupling with electromagnetic fields.
- Do NOT connect the low impedance input directly to 70 / 100 V constant voltage lines.
HORIZONTAL HANGING
Up to 4 x Q, 15 can be hanged horizontally by using the horizontal flybar FLY
BAR FL-B H Q 15.
HORIZONTAL HANGING OF 1 SPEAKER
- Unscrew the 4 central screws from the Top Plate
