Multi-Purpose Loudspeaker User Manual

APPLICATION: Twin X series of foreground/back-ground music speakers designed for demanding
professional applications such as the reproduction and reinforcement of music and sound in venues as
diverse as discotheques, airports, places of worship, retail premises, restaurants and public houses.
DESCRIPTION:Twin-8X, 1 x 8” coaxial two-way full-range drive unit plus 2” HF driver, trapezoid, ported
acoustically-efficient enclosure.Twin-10X, 1 x 10” coaxial two-way full-range drive unit plus 2” HF driver,
trapezoid, ported acoustically-efficient enclosure. Twin-12X, 1 x 12” coaxial two-way full-range drive unit plus
2” HF drive unit, trapezoid, ported acoustically-efficient enclosure.Twin-15X, 1 x 15” coaxial two-way full-
range drive unit plus 2” HF drive unit, trapezoid, ported acoustically-efficient enclosure.
SUB BASS UNITS: Twin-15XSB, 1 x 15” bass unit, rectangular, ported acoustically-efficient enclosure.Twin-
18XSB, 1 x 18” bass unit, rectangular, ported acoustically-efficient enclosure.
CONSTRUCTION: All units are constructed from birch plywood. All full range units are fitted with a full steel
grille. Subwoofers are fitted with a partial steel grille.
FINISH: All Twin X models are available in a black or white impact resistant multiple layered paint finish with
rugged metal grille with acoustic foam backing as standard.
DEPLOYMENT: The Twin-X can be mounted in a vertical or horizontal position using the mounting bracket
hardware. All models have been designed for installation with the use of suitable ancilliary commercial
mounting equipment. They can be installed on the wall or ceiling flush mounted, or combined in groups of
two and four in a column or on floor stands.
IMPORTANT NOTE See Warning Section on RIGGING • SUSPENDING • MOUNTING
before attempting to
install Wharfedale Pro Twin-X series of speakers.
Ensure you use the M10 eyebolts for any mounting hardware used with the Twin-X.
HF PROTECTION: The Twin X series speakers are equipped with The “PRO-TECH”™ System, a dynamic
tweeter protection circuit, composed of an accurate and sensitive protection lamp. When high signal levels
are present that may pose a dangerous overload for the tweeter coil, the protection circuit will activate
immediately to limit the power sent to the transducer.
OSE LOUDSPEAKER SYSTEMS
OPERATION/USE:
1. The Twin-X Series will accept cables with Speakon™ connectors. The units feature two Speakon™ type
connectors situated at the rear of each cabinet. This type of connection is easy to use as it requires no
additional solder. The rear of the unit will feature two parallel sockets labelled ‘Input’ and ‘Output’. The pins of
these sockets are paralleled with the unit itself. Pin +1 is positive and Pin -1 is negative in accordance with
standard wiring regulations (see diagram below). The SUB models feature an additional Speakon Hi Pass
output. These are connected in parallel. Take care to avoid adding too many Twin-X Series speakers in series.
Each speaker connected in series increases the load on the amplifier and can add up to a total load that may
exceed the amplifier’s capabilities, leading to possible damage. Two 8 Ω loudspeakers in series make a 4Ω total
load. Four 8Ω series connected loudspeakers make a total load of 2Ω, which is too low for many amplifiers.
2. Attach the speaker cable securely to your Twin-X unit and power amplifier (the amplifier should be off, power
down mode). Where possible use Speakon™ connectors as they are professional high current connections
specifically designed for this application. Try to use the correct type of speaker cable according to the handling
ability of your Twin X cabinet. Use 2 core equal stranded insulated cable for speaker runs. It is always advisable to
use heavier conductor cables on longer runs.
3. If using Speakon™, insert the speakon and rotate 1/8 of a turn until locked in.
4. Power up amplifier with levels on zero. Confirm units are operating.
5. Take care to try and avoid running the amplifier into clip (overdriving) for any length of time as this will result in damage to the
voice coil of the loudspeakers.
6. If you are using amplifiers from different manufacturers then make sure the gain variation between the models is less than
+/-5dB.
