3. allows for flexible choice of the amplifiers used between the HDP 3 preamp processor and the loudspeaker drivers The two sets of and terminals at the back of each of the Kebi and Kumbar modules allow each driver to be directly connected to its matching power amplifier for improved control and speed of response The amplifiers can even be located adjacent to the loudspeakers to minimise the length of speaker cable We highly recommend using the state of the art DEQX HDA 3 4 amplifiers Sporting proprietary discrete component linear circuits with zero global feedback they afford stunningly fast articulate and silky smooth output Each HDA 3 4 amplifier has four channels that can provide 400 Watts of power to each of the stereo speakers So two DEQX HDA 3 4 amps are used to drive all eight drivers in a stereo pair of Tikandi loudspeakers Alternatively one can use multi channel home theatre amplifiers to connect each driver to its own amplification An example would be the 8 channel Marantz MM8s003 amplifier It is also possible to have the channels of amplification provided by multiple stereo amplifiers each tailored to the type of driver woofer midrange tweeter it is paired with Of course the benefits of mono blocks can be fully employed with the Tikandi system as well Ideally the amplifiers should provide roughly the same voltage gain though the DEQX HDP 3 processor can adjust the output gain separately for each channel You

30. s of amplification The 2 boxes of 4 channels of amplification may be replaced by alternative arrangements with similar connection procedures as above For example some 7 1 home theatre amplifiers have 8 channels of amplification built into a single box the Marantz MM8003 amplifier is one such box and we have found this amplifier to be very successful with the Tikandis The main feature to watch is that the amplifier has enough power current capabilities required for 4 ohm load of each bass driver given the large cone excursions at frequencies as low as 20Hz Each channel connected to the bass drivers should have a minimum of 100W or 5 amps current delivery The mid drivers typically require 30 5OW while the tweeters 15 20W Alternatives for providing the 8 channels of amplifiers as described above is to use four stereo amplifiers or even 8 monoblocks Providing they meet the power requirements described above the amplifiers do not have to be of the Same type or brand except for each type of loudspeaker driver so for example both left and right tweeters for example mids should use the same amplifier model This may allow you to use your existing amplifiers and to tailor the amplifiers to each type of driver for example pure class A low powered amps to the tweeters The amps do not have to have identical gain as the output gain from each channel can be set inside the HDP3 though you will have to consult the accompanying DEQX
31. s sitting in a single sweet spot less critical and enhances the enjoyment of your system If your listening room is regularly shaped you can improve its performance by judicious use of cupboards bookshelves furniture and curtains to break up or absorb the reflected waves You should try to avoid sitting on the diagonals between the opposite corners of the room where the room s standing waves are maximised If possible you should also experiment with positioning of the speakers to find out where they sound best for your music in your room Reflected waves by arriving later at the ear confound the sonic image of the sound stage To optimise the soundstage the Tikandis should be placed at least 0 5 m from any reflecting surface particularly from side walls Ideally you would sit near the apex of an approximately equal sided triangle formed with the speakers 2 4 m 7 13 ft apart Good results can be achieved with the Speakers roughly 20 of the room s width from the side walls although the Tikandis do have an unusually large sweet spot so this is not critical Unlike traditional passive speakers the Tikandi s dispersion at high frequencies is so remarkable that they do not need to be to be aimed directly at the listening position The Tikandi speakers may be toed in roughly mid way between pointing parallel to the side walls and pointing at the shoulders of a person sitting in the central listening position Thi
