INSTALLING AND POSITIONING
when choosing a suitable location for the monitors, bear in mind that the physical mounting of loudspeakers and their
proximity to room boundaries can have a large influence on performance. For best results the monitors should be
mounted on a heavy rigid structure, supported on four pads making contact with the base of the loudspeaker. The use of
small pads of rubber, sorbothane, or Blu-Tak is recommended.
ensure that the console position does not obscure the direct sound radiation from the loudspeakers when sitting at the
mixing position. The engineer and producer should have a clear, uninterrupted view of the monitor loudspeakers.
3.1 SURROUND MONITORING
To ensure a uniform acoustical monitoring environment the room should be symmetrical about the centre or dialogue
loudspeaker axis and any acoustic room treatments should be applied symmetrically on either side of the room. Mixed
"Live end/Dead end" environments should be avoided. If the effects or surround sound loudspeakers are positioned close
to walls then the constitution of the wall surfaces should be identical.
when using either ellipse 8 passive or 10 passive as the main effects speaker for the front soundstage, placement is
a critical factor for good performance. in all cases the centre channel speaker should be placed as close to the viewing
screen as possible. The viewing position when seated determines the ideal mounting height, but in all cases this should
be as close as possible to ear height. If this is not possible the monitor should be tilted towards ear height in the mix
position. The centre speaker should be positioned along the centre axis of the picture and the left/right monitors just
outside the picture. Ideally the three front effects speakers should be placed with the front baffles in line with the screen
surface. if an acoustically transparent screen is used, the left/right monitors should be placed just inside the edges of
the picture. The surround speakers should be positioned at the same distance from the mix position as the main
front speakers.

a subwoofer is recommended, chosen from the Tannoy range to ensure compatibility. The subwoofer/lFe channel
produces low frequencies which are non-directional and therefore the subwoofer can theoretically be placed anywhere
in the room. However, from experience, optimum performance will be gained by placing the subwoofer in the same plane
as the main front speakers. The LFE channel is set at a level 10dB higher than the other channels when mixing therefore
it is important to apply the same in any playback situation.
3.2 BASS PORTS
The ellipse passive monitors' bass ports are located on the front panel. You should keep the back panels at least 300mm
(12") away from the nearest wall surface to avoid an overblown bass sound. If you cannot avoid being close to a wall you
may want to consider plugging the port tubes on your ellipse 8 passive monitors with the closed cell foam-rubber plugs
supplied as an accessory within the pack. They are a friction fit for a full seal. This will overdamp the bass alignment of
the monitors making them more suitable for 2Pi environments such as for example against a wall or mounted on a large
flat surface. Ellipse 10 Passive monitors should be equalized electronically in these circumstances.
3.3 EQUALISATION
our feeling is that you shouldn't need to equalise monitors at all in a well designed monitoring environment; apparent
12
variations in the monitor response should be fixed through room design or speaker placement. But we realise that
equalisation is sometimes a necessary evil especially in small rooms or where the monitors are close to room
13
boundaries. We recommend a good quality speaker controller with digital filtering. Any frequency shaping should be low
Q, smooth and you should make use of shelving responses in the frequency range 200Hz to 800Hz. no two adjacent 1/3
14
octave bands should differ by more than 1dB. if you have a choice of equalisers for monitor applications, less is more.
The fewer the number of filters, the better the equaliser will sound. Over equalisation can reduce system headroom,
15
and introduce phase distortion resulting in greater problems than cures. always check out the result of equalisation by
16
listening to well recorded vocals or male and female speech from a familiar source.
