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 roll-
off 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.

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.
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).

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,
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.
