User manual TANNOY ELLIPSE DESCRIPTION

[. . . ] The HF unit has a high sensitivity of up to 105 dB for 2. 83 volts, so that its dedicated power amp, 150W on the Ellipse 8 and 200W on the 10, normally runs with over 20dB headroom to ensure uncompressed dynamics. It's high sensitivity also means it's average power consumption on normal programme material is only one or two watts, so there's minimal thermal compression compared to low-sensitivity dome HF units. 3 DUAL CONCENTRIC (LF Unit) ­ 40Hz-1. 7kHz Polypropylene cone, long throw driver with cast alloy chassis where the cone profile continues the exponential horn of the HF unit. Using complex filtering, it is accurately time-aligned with the HF unit, so they are not only on the same axis, but also in the same plane. [. . . ] Flashing red gives instantaneous indication of voltage or current clipping in the LF amplifier. The unique feature of the indicator is the VLF (very low frequency) warning. When there is a significant level of subsonic content in the mix (typically between 1Hz-15Hz) the built-in LF hi-pass filtering prevents it from causing excessive cone movement and draining amplifier power, as would happen in a conventional passive monitoring set-up. To represent cone-flap, and warn of VLF content, the LED will flash yellow with every positive and negative half cycle of the offending WESTLAKE AUDIO, LOS ANGELES, CALIFORNIA signal. Recording, mixing and mastering engineers are therefore given the opportunity to take remedial action if required. 5 SUPERTWEETER ­ 14kHz-50kHz The pod mounted SuperTweeterTM uses a specially developed aluminium alloy and carbon fibre dome with rare earth magnet and continues the frequency response to over 50kHz. It is driven by a dedicated 30W IC power amp, and time-aligned to the Dual ConcentricTM over a wide horizontal dispersion using fourth order Gaussian hi-pass filter and critical physical positioning. The SuperTweeterTM amplifier bandwidth is up to 80kHz. The crossover frequency is very high at 14kHz, which is far away from the midband where sensitive stereo location information is concentrated. At this frequency it doesn't interfere with the main signal from the Dual ConcentricTM. Listening at 1 metre on axis with the HF horn, which is the precise point where its signal synchronises with the Dual ConcentricTM, it is not detectable as a separate source. 6 5 8 AMPLIFIER MODULE Behind the elegant cast multi-fingered heatsink, which has 60% higher efficiency than a vaned heatsink of equivalent size, lies the surface-mount PCB. The circuit carries 20 ultra-low distortion, lownoise audio op-amps, which provide comprehensive Analogue Signal Processing and power amplifier driver stages. LF and HF bands have identical design 150W or 200W discrete mosfet power amps. The SuperTweeterTM is powered by a monolithic 30W wide bandwidth amplifier, which gives ample headroom for the minute signal in this audio band. The ASP used comprises high and low order frequency dividing networks, fixed and variable equalisation, and high Q inductive/capacitive correction filters. There is no compression or limiting on board, to preserve dynamics. The system can be driven into clipping, and damage can result from abuse, but it's a system designed for professionals who want to hear the true dynamics of their work. 1 3 4 9 6 MAINS INLET MODULE A four-in-one mains inlet comprising earthed 6A IEC socket, on-off switch, fuseholder, and voltage selector. 7 XLR BALANCED INPUT A variable gain instrumentation amplifier input stage with high CMRR is used, with local grounding and high RFI rejection. 9 RESILIENT BASE Secure mounting is provided by the detachable neoprene base, which effectively dampens any vibration between the loudspeaker and the stand or platform support. [. . . ] So, even if we ignore for now the perception of sound above 20kHz, the addition of the SuperTweeterTM gives a more realistic soundstage by improving imaging and placement of instruments. With 96kHz and 192kHz digital recording systems rapidly becoming the norm in today's recording environment, you need to be sure that your recordings are faithfully reproducing the original sound. Tannoy Wideband Technology monitors help ensure that whatever you record will sound as good when played back on the new generation of wideband commercial and home audio systems.
