2. 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 a 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 1500 W power rating.

Directivity, horizontal 22.5° and vertical 60° (Q 15), 90° (Q 15-L), 40° (Q 15-P) makes 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 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.

3. CONNECTIONS

THE REAR PANEL

The rear panel displays 2 sockets, both for 'Neutrik Speakon NL4' (4-pole) plugs:

① The INPUT socket receives the signal from the amplifier
② 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 the pin 1- of the SPEAKON connector
• High frequency amplifier + output to the pin 2+ of the SPEAKON connector
• High frequency amplifier - output to the 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.

3. CONNECTIONS

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 an 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 mains cables, microphone cables or others, in order to avoid inductive phenomena 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.
