1. READ INSTRUCTIONS carefully before operating this product.

2. RETAIN these instructions.

3. COMPLY WITH WARNINGS - All warnings and instructions for this product should be adhered to.

4. USE WITH AMPLIFIERS - In order to avoid damage, it is advisable to establish and follow a pattern for turning on and off any sound system. With all system parts connected, turn on source equipment, tape decks, instruments, mixers, signal processors etc., BEFORE turning on your power amplifier. Many products output turn on and turn off transients that can damage speakers. By turning on your power amplifier LAST and making sure the amplifier’s input controls are at minimum any transients “upstream” of the amplifier are not amplified and passed to the speaker. Wait until all system parts have stabilised, then bring up amplifier controls to operating level. This should take no more than a few seconds. Similarly when shutting systems down, always turn down amplifier input controls and then turn off your amplifier BEFORE shutting down other components. Professional amplifiers often feature delayed turn on/off circuits to perform these functions for you automatically.

5. CABLES - Never use shielded or microphone cable for any speaker connection as this will not be heavy enough to handle the amplifier load and could cause damage to the complete system.

6.

INTRODUCTION:

The TWIN-X is capable of delivering high SPL’s in even the most demanding applications and exhibits true constant directivity, providing an even frequency response over the entire area of coverage.

The TWIN-X full range cabinet comprises one sophisticated low frequency (LF) driver and high frequency (HF) sources are exactly aligned to a point source, resulting in a smooth uniform frequency response over a wide area of coverage either as a portable stand alone system or in a multi-cabinet array. As the system is a point source, clusters and arrays have minimal lobing. These features are inherent and achieved without the use of any electronic signal processing.

The asymmetric cabinet profile allows flexible and discreet installation. As a foreground system, installation is made simple with any type of mounting hardware or the system can be flown using the integral M10 inserts.

For portable stage use the birch ply cabinet has a recessed carrying handle on the rear of the cabinet. As a versatile low profile stage monitor, the conical coverage pattern gives the performer greater freedom of movement.

Equalisation:

The TWIN-X loudspeaker is designed to need no equalisation or correction to overcome system limitations. As a result, it will only need equalisation to compensate for difficult acoustic environments.

Over equalisation can reduce system headroom, and introduce phase distortion resulting in greater problems than cures. If equalisation is required then it should be applied gently and smoothly. The TWIN-X loudspeaker is a point source, phase coherent design and violent equalisation will be detrimental to the overall sound quality.

When a loudspeaker is used in close proximity to another, comb filtering effects can create coverage problems, comb filtering creates an uneven frequency response across the coverage area due to constructive and destructive interference effects between the sources. The amount of comb filtering is affected by the spacing fo the relative sound sources. Minimising this effect cannot be cured by equalisation.

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.

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 4

Ω total load. Four 8

Ω series connected loudspeakers make a total load of 2

Ω

, 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.
