TECHNOLOGY
A Tannoy
WIDE
BAND™
High Frequency Module is incorporated into the design of all
Eyris models, not only to resolve fine detail of high frequency information but also to
effectively enhance the listening experience throughout the whole frequency range. The
WIDE
BAND™
high frequency system creates an increased immediacy, airiness and
impact making music sound more natural and true to life.
Music contains transient information and rich harmonics beyond the range of human
hearing for pure tones. Even bass notes have leading edge transients reaching 30kHz.
Operating between the roll-off point of the exclusive Tannoy mid-bass driver unit and
44kHz, the Tannoy Eyris
WIDE
BAND™
high frequency unit will accurately reproduce
the leading edge of individual notes allowing the listener to experience the entire bandwidth
information of instruments.
In addition, by extending the frequency response by two octaves corrects time and phase
response within the bandwidth of normal human hearing. Taking these acoustical phase
anomalies beyond the range of human hearing adds realism to the soundstage by
improving imaging and placement of instruments.
AMPLIFIER CHOICE
Consult the enclosed product specification sheet as this clearly shows the acceptable power
range for amplifier matching to your speakers. The high peak power handling of Tannoy
loudspeakers permits responsible use with more powerful amplifiers - please read the
Warranty.
As with all loudspeaker systems, the power handling is a function of voice coil thermal
capacity. Care should be taken to avoid overdriving any amplifier, as this will cause output
overload resulting in 'clipping' or distortion within the output signal. This, if done for any
extended period, will cause damage to the speakers.
Generally an amplifier of higher power that is running hard, but free of distortion, will
do less damage to the loudspeaker than a lower power amplifier continually clipping.
Remember also that a high powered amplifier running at less than 90% of output power
generally sounds a great deal better than a lower powered example struggling to achieve
100%. An amplifier with insufficient drive capability will not allow the full performance of
the loudspeakers to be realised.
CABLE CHOICE
Always use the best quality of cable available within your budget. High quality audio
signals passing from the amplifier to the loudspeaker are unusual in their demands on
the cable. Wide dynamic range and frequency bandwidth information has to coexist with
the ability to transmit peak currents of at least 10amps, without incurring any loss or signal
impairment. This explains why the sound quality of the information reproduced by the
loudspeakers is so dependant on the physical properties of the cables connecting them
to the amplifier.
We would recommend that you always keep the cable runs the same length for each
speaker.
Remember, cable construction can affect the sound quality so be prepared to experiment
to find a cable that suits your ear and audio system.
TERMINAL PANEL
(See fig. 2)
In order to take advantage of the driver earthing feature within the Eyris range and to
optimise performance further, use a shielded or screened loudspeaker cable. The screening
termination should be connected to the earth or 'ground' (green) terminal on the loudspeaker
and to the ground or earth connection on the amplifier. Alternatively if you are not using
a screened loudspeaker cable but wish to utilise the earthing facility, run a single cable
between the earth or 'ground' (green) terminal on the loudspeaker to the earth (ground)
connection on the amplifier.
