Service

There are no user-serviceable parts inside. Qualified personnel must perform all service. Servicing is required when: -

The unit has been damaged in any way, such as when the power-supply cord or plug is damaged.

The unit has been exposed to rain or moisture, or liquid has been spilled into the unit.

EUROPEAN MODELS

A mains cable is supplied with an IEC moulded socket at one end and a moulded mains plug at the other end. Where the moulded plug is fitted with a mains fuse, always replace with the same 5A rated fuse. If the fitted plug is unsuitable for your type of outlet sockets, it should be cut off and disposed of safely, in case it is inserted into a live socket elsewhere. The wires in the mains cable are coloured in accordance with the following code:

GREEN AND YELLOW EARTH

BLUE NEUTRAL

BROWN LIVE

3

AS THE COLOURS OF THE WIRES IN THE MAINS CABLE MAY NOT CORRESPOND WITH THE COLOURED MARKINGS IDENTIFYING THE TERMINALS IN YOUR PLUG, PROCEED AS FOLLOWS:

The wire which is coloured GREEN AND YELLOW must be connected to the terminal in the plug which is marked either by the letter E, the earth safety symbol, or coloured GREEN or GREEN and YELLOW.

The wire which is coloured BLUE must be connected to the terminal in the plug which is marked by the letter N or coloured BLACK

The wire which is coloured BROWN must be connected to the terminal in the plug which is marked by the letter L or coloured RED.

Ensure that the terminals are tightened securely, and no loose strands of wire are present. Ensure cord grip is clamped over outer sheath of cable, rather than over the wires.

FUSE PROTECTION

An additional mains fuse is provided in the IEC power inlet on the back of the loudspeaker, which can only be removed with the power cord unplugged. This must be replaced by a fuse of the same type and ratings (see Specifications or refer to rear panel).

INSTALLATION

Do not install this equipment in an enclosed space. Do not limit free ventilation and movement of air around the back panel. Do not install this equipment in a cupboard with a closed door. Allow for a distance of 150mm (6 inches) of free air space around all sides, top, bottom and the back panel of this product. The user must be able to see the blue coloured front panel of this product when in use.

1.1: INTRODUCTION

Taking full advantage of significant advances in digital speaker measuring techniques such as Klippell™ symmetry and nonlinear distortion analysis, laser scanning interferometry, acoustic CAD simulation and our own cutting edge acoustic technologies, Tannoy engineers have developed two new active monitors. The new Precision D range incorporates the latest Tannoy Dual Concentric™ driver and WideBand™ Technology to deliver near field monitoring speaker designs that set new standards of acoustic performance and accuracy.

Precision D active monitors provide superior bandwidth, significantly low levels of distortion, very smooth response, extremely accurate phase control, high sensitivity levels and input source flexibility. Add in a comprehensive calibrated EQ facility for mid / near / close field working in full / half /quarter and eighth space environments, midband and high frequency trim shelving controls, a choice of power and cabinet sizes, analogue and digital input trim facilities, and user requirements can be satisfied for all listening environments and applications.

Tannoy’s core technology, the Dual Concentric™ is unlike ordinary drive units in that it is effectively two drivers, properly merged into one. The high-frequency unit is positioned on the back of the low frequency driver so that they are on the same axis. As a result sound energy is propagated from the same point and delivered through the centre of the low frequency cone providing a true point source. This integrated approach provides a constant time delay over the frequency spectrum offering better transient performance and sound quality with better harmonic alignment than a displaced source monitor design. The crucial benefit at the mix position is the delivery of a more natural and cleaner sound with greatly enhanced intelligibility.

Characteristic of the Dual design is a very wide 'sweet spot' with an exceptionally even response throughout the listening area and extraordinary transient response. This phase accurate Tannoy designed drive unit has, for all these reasons, been the choice of professional studio engineers for decades.

Tannoy has been at the forefront of developing loudspeakers with WideBand™ performance. Extending the high frequency rolloff out to 51kHz corrects the time or phase response at the upper end of audibility, resulting in enhanced accuracy and ‘air’, improved clarity within the essential mid band area, and even enhancing definition of low frequencies. Tannoy WideBand™ Technology is an essential component of the Precision monitor design delivering increased tonal accuracy of the individual instruments in the recording process - a mix-critical factor allowing the best EQ and placement decisions to be made.

Tannoy engineers have researched ways of dealing effectively with the acoustic effects of mid, near and close field listening distances, in order to compensate for the relative size and distance of the acoustic source and resultant spherical / plane wave dilemmas. Additionally, the effect of boundaries near a monitor speaker, such as walls, support tables and mixing console surfaces can change the air load on the low frequency cone piston and consequently the radiating efficiency in the 100Hz to 800Hz region.

A set of DIP switches on the rear control panel of the new Precision D active monitors allow the selection of an optimum speaker response for real life and often difficult monitoring situations so that the frequency response at the listener’s ears is always as linear and flat as possible. Optimisation can be preset for far field (>2m), mid field (1to 2m), near field (0.5 to 1m) and close field (<0.5m) situations in combination with free space (4pi), half space (2pi), quarter space (pi) and extreme eighth space (pi/2) corner situations. Precision D Active monitors can therefore be optimised for varying listening distances in difficult acoustic spaces; varying meter bridge positions, against and adjacent to walls or reflecting surfaces, in corners, in corners on shelves or brackets, table top / space restricted PC/Mac based sound editing environments and stand mounted or soffit mounted configurations. (see graph overlleaf).

2.0: THE BASICS 2.1: UNPACKING AND VISUAL CHECKS

The Precision 6 and precision 8 are packed singly. To remove the speaker from the carton without damage open the end flaps fully and bend them right back. Turn the package upside-down on the floor and lift the carton vertically up to leave the speakers resting on their packing tray. Nothing on or in your speakers should rattle about. Inspect each speaker for signs of transit damage. In the unlikely event of this having occurred inform the carrier and the supplier. Keep all the packaging if damage has occurred, as this will show evidence of excessive handling forces. It is also a good idea to keep the packaging if possible for future transportation.

2.2: PRELIMINARY RECOMMENDATION

Initially we would like to give a word of warning on high sound levels, which these speakers are capable of generating over sustained periods of time. Levels over 95 dB for 8 hours per day can eventually cause permanent hearing loss. Because Tannoy monitors have very low levels of time, amplitude and frequency distortion it is not always obvious that the sound level is high while working with them.

For continuous exposure we recommend the occasional use of a sound level meter capable of integrating the sound level over a period of exposure according to noise control standards. This should be used just to check that noise levels are always within safety limits.

3.0: PRECISION D SERIES FEATURES

A set of DIP switches on the rear panel of each speaker can be set to choose the optimum speaker response for real life and often difficult situations, so that the frequency response from the speaker is always substantially flat. We are not equalising the room modes due to standing waves or resonant structures, we are equalising the speaker to take account of the varying air load presented by the room and surrounding large structures such as the mixing desk.

The switches are arranged in groups according to their function and each switch can be set to the 'on' (down) or 'off' (up) position in various combinations to achieve a flatter, more balanced response within a wide variety of acoustic spaces and with far, mid, near and close field monitoring positions.

Figure 1 shows the range of equalisation available in the 50Hz to 800Hz region and also shows the degree of trim available in the bass, upper midrange and high frequency areas,
