3 1.2: power requirements important: • check voltage selector is correctly set on the mains input module. The factory set voltage rating is displayed on the iec mains input module on the rear panel - see fig 1 (page 4). • check that this setting is correct for your area before powering up the system...

5 power cable configuration a mains cable is supplied with an iec moulded socket at one end and a moulded mains plug, appropriate to the country of use, 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 ...

6 1.3: design philosophy the design of an active monitoring system encompasses many interdependent components: drive units, enclosure, amplifiers and so on. For the ellipse development programme, each element has been re-examined, looking for new ways of doing things, free of the limitations imposed...

7 2.0: installation 2.1: unpacking and visual checks to remove the speakers from the carton without damage, open the box in the upright position and fold back the four flaps. Remove the top foam packaging and power cable then lift the unit out by gripping the cabinet, not the tweeter pod. Place the ...

8 3.0: placement of the speakers 3.1: positioning speaker placement, and the listening environment itself, can completely compromise the performance of any loudspeaker. It is important to understand some of the positional limitations of near-field speakers, and the operating environment, in order fo...

9 3.4: setting the level the sensitivity control allows for use with a wide range of equipment. Although the two signal levels widely used are nominally +4dbu and -10dbu, the whole area of reference levels is highly confused, with different levels being adopted by different manufacturers, broadcaste...

4.0: design features 4.1: amplifier stages the input xlr is directly connected to the chassis with a grounding pin on pin 1. Pin 2 is the non-inverting input and pin 3 is the inverting input. Pins 2 & 3 connect to an electronically balanced, variable gain instrumentation amplifier, which has identic...

4.2: asp the analogue signal processing used in tannoy ellipse comprises high and low order frequency dividing networks, fixed and variable equalisation, and tuned lc correction filters. This elaborate circuitry is used to achieve a flat frequency response and exceptionally accurate time-alignment a...

4.4: active crossover the integrated active crossover, which splits the input signal into lf and hf separate amplification channels, has been designed using a dedicated computer simulation program. The result is an unconventional topology giving optimum electronic transfer functions, i.E. Achieving ...

4.7: trim controls the primary function of the trim controls is to compensate for room effects. How a monitoring system sounds and measures is obviously affected by room acoustics, a major factor being the monitor's proximity to boundaries. If placed close to a wall the main effect is a low frequenc...

8.3: amplifier a fuse is located just under the mains input (location 2 fig 1) . Replacement is simple and a spare fuse is provided inside the fuse housing itself. Always use the correctly rated fuse, as indicated on the silk screen-printing. Only qualified and authorised personnel should undertake ...
