Connect the TDAI-2170 to the mains power and turn on the mains switch.\n4. Switch on the TDAI-2170 using the front stand-by button.\n\nWhen the TDAI- 2170 is turned on for the first time, the Speaker\nSetup Guide will start. This guide will ensure that you pass through\nthe full setup process, but you can always back out of this guide by\na long press on the Source/Menu button.\n\nSettings can be modified later under the Output Menu – or you\ncan activate the Speaker Setup Guide to start all over.\n\nWhen connecting the speakers, always connect + and - from the\namplifier to the corresponding + and - terminals on the speaker.\n\n**Warning** :\nNever run the TDAI-2170 in bridged mode with other amplifiers – nor should you never connect speaker cables to\n‘High Level’ inputs on a subwoofer. Connecting the speaker output terminals of two amplifiers will, because of the\nway a fully digital amplifier works, seriously damage the amplifier.\n\n**Tips for setting up speakers**\nYou can use the stereo triangle as a good rule of thumb\nwhen determining where to place your speakers. The\ndistance between the speakers should be the same as the\ndistance from your listening position to both speakers.\n\nIf your room does not accommodate the optimal listening\nsetup, the TDAI- 2170 can compensate for this, when you\nenter the actual distances to each speaker through the", "page": 18 }, { "title": "Speaker setup guide", "content": "Reflections and Echoes\nThe direct sound from the speakers is strongly affected by\nthe dimensions of the room and the surfaces of the walls,\nfloor and ceiling.

Find the position of the diffusers by having\nsomeone hold a mirror flat against the wall or\nfloor. When you can see the speaker in the\nmirror from the listening position, you have\nfound the optimal position for the diffuser.\n\n**Note:**\nReducing reflections can also be achieved by spreading the direct reflection – these are known as diffusers. We do not\nrecommend extreme dampening of the room reflections – like in a public cinema. RoomPerfect™ works optimally in a\nroom with comfortable acoustics.\n\n**Speaker placement with RoomPerfect™**\nTraditionally speakers must be positioned in the room with different distances to back and side walls, so that sound\nreflecting from the walls does not reach your ear at the same time. This is to optimize the frequency response, but at\nthe cost of timing, as the reflections are causing a beat to be smeared out over a longer time.\n\n**With a RoomPerfect™ calibration** you can optimize the timing by placing your speakers against the back wall,\nopposite from your preferred listening position. This will ensure the largest sound reflection from the back-wall and\nthe direct sound will reach your ears at the same time, giving you better timing. The damage to the frequency\nresponse will be cleaned by RoomPerfect™\n\nIf your speakers have a bass-reflex port on the back, you should allow for a 5cm/2in clearance to the back wall. This\nwill ensure there is no disruption to the functionality of the port.\n\n**Connecting a subwoofer**\nThe TDAI-2170 features a crossover function for optimal\nintegration with a subwoofer.\n\nWhen connecting to a Lyngdorf BW type subwoofer, you connect\nthe analog output of the TDAI-2170 to the BYPASS input of the\nsubwoofer.\n\nIn a traditional single subwoofer setup, connect the subwoofer to\nthe left analog output on the TDAI-2170.

The height and the\norientation of the microphone should correspond to\nyour head’s height and direction.\n\nPress enter and a test signal will start from the left\nspeaker. The TDAI-2170 will give an estimated\noptimal volume for calibrating the system or will\naccept the current volume. Adjust the volume if\nrequired and retry the measurement.\n\nThe calibration volume should not be so loud that it is inconvenient to you, or that it causes damage to your\nloudspeakers. If this is the case, set it to a lower and more appropriate level. A low volume can result in a longer\ncalibration time (in excess of two minutes) or a measurement time out. A low volume and long measurement will not\naffect the quality of the result.\n\n**Measuring the focus position**\nWhen the calibration volume has been set, RoomPerfect™ will send a range of tones to measure the focus position. If\nthere is noise in the room, the measurement may take longer. This will not affect the quality of the result.\n\nSee “RoomPerfect troubleshooting” on page 18 if you experience problems.\n\n**Measuring random room positions**\nWhen the focus position has been measured, the next step is to measure the acoustical properties of the room. It is\nimportant to perform well spaced measurements to get a comprehensive image of the acoustical properties of the\nroom. See “RoomPerfect troubleshooting” on page 18 if the measurement stops prematurely.\n\nKeep taking measurements until Room Knowledge reaches 90%, when the system has enough information to do a\ncalibration.\n\nThese are the rules of thumb when measuring the room:\n\n\n- the microphone must always have a clear line of\n sight to the tweeter mid-range of the speaker.\n- the microphone should be in random and varying\n positions, heights, and orientations.\n Point it up/down/sideways, the more random\n positions the better.\n- the measurements should cover the entire room,\n not only your listening area.\n- the microphone should not be closer than\n 0.5m/1.5ft from the floor, ceiling and walls.\n- the microphone should be at least 1m/3ft from the\n front of the loudspeakers.\n- there should be at least 50cm/1.5ft between each\n measurement.\n- do NOT take symmetrical measurements in the room.\n\n**Room measurements above 90% Room Knowledge**\nNote that Room Knowledge is calculated by the computer as how much from the new measurement it already knows.\nIf the Room Knowledge index does not increase after a measurement, you have added a good measurement with a lot\nof new information.\n\nTo fully optimize RoomPerfect™’s understanding of the room’s acoustical properties, we recommend you keep doing\nmeasurements until the Room Knowledge is above 95%. The higher the Room Knowledge, the more accurate the\nroom correction filters will be.\n\n**4.2.2 Status**\nThis screen shows how many room measurements have been made, together with the RoomKnowledge and\nRoomCorrection index.\n\nThe Room Knowledge index is an estimate of how much of the room’s acoustical properties have been learned from\nthe room measurements. The higher the Room Knowledge index, the greater the accuracy of the calibration.\n\nThe Room Correction index is an estimate of how much the calibration filter will affect the sound reproduction by\nevaluating the size of the filters as well as the frequencies adjusted. This index is not absolute. For best results, rely on\nyour own experience of the effects of the filter.\n\nA low Room Correction filter on the focus position could indicate that you have positioned your speakers in order to\noptimize the frequency response and not the timing.\n\nCheck “Tips for setting up speakers” on page 6 and complete a new RoomPerfect™ calibration.\n\n**4.2.3 Add focus position**\nIf you would like to add an additional focus position, the chair next to the couch perhaps, it can be done here. It is\npossible to have up to 8 different focus positions.\n\nThe saved calibration volume from the RoomPerfect™ guided setup is used as a default when adding extra focus\npositions. The volume can be changed at any time between measurements to suit a particular situation. This will not\naffect the quality of the measurement or the end result.\n\n**Add room measurement**\n\n```\n0.5 m / 1.5ft\n```\n```\n0.5 m / 1.5ft\n```\n```\nMin.\n0.5m /\n1.5ft 1m /\n3ft\n```\n```\nMin.\n0.5m\n1.5ft\n```\n```\n1m /\n3ft\n```\n```\n0.5 m / 1.5ft\n```\n\nIt is possible to add more room measurements, which can increase RoomKnowledge and thereby fine tune all the\nroom correction filters.\n\n**Status**\nThis screen shows how many room measurements have been made, together with the Room Knowledge and Room\nCorrection index.\n\nThe Room Knowledge index is an estimate of how much of the room’s acoustical properties have been learned from\nthe room measurements.

This indicates that each\nmeasurement holds new data for the calibration.
