    The amount of recommended "toe-in" is a function of the lis- tening angle. As the overall listening angle increases from 40 degrees, the amount of toe-in should increase. Your Legacy speaker is optimized for a flat response in the far field. Best results are obtained vertically with the lis- tener's ear at tweeter level with the loudspeakers gently toed in toward the listener.

  • Page 8: Hooking Up Cables

    Hooking Up Cables The ideal conductor would have negligible resistance, inductance and capacitance. The table below shows how a few actual speaker cables measure up. Cable s/ft pF/ft µH/ft 12 ga. 0.0033 0.21 14 ga. 0.0048 0.13 16 ga. 0.0079 0.18 18 ga.

  • Page 9: Hooking Up Cables

    Hooking Up Cables What about phase shift due to frequency dependent travel times down the speaker cable? Measurements show that 100 Hz waves will be delayed about 20 billionths of a second behind 10 kHz waves when traveling to the end of a 10 foot speaker cable. Since the cilia of the ear requires 25,000 times longer than this just to transmit phase information, phase shifting is obviously not the primary concern when considering speaker cables.

  • Page 10: Amplification

    For this reason, extensive measures have been taken to ensure that each Legacy speaker system represents a smooth, non-reactive load to virtually any amplifier. Often there is much confusion regarding amplification and loudness levels. It should be under- stood that the role of the amplifier goes beyond that of driving loudspeakers to a given sound pressure level.
  • Page 11 Some audiophiles feel that 200 watts per channel is the bare minimum to avoid audible clipping distortion when reproducing music at “live” playback levels. Your Legacy speakers are designed to take advan- tage of “high-powered” amplifiers, so don’t be afraid to put them through their paces.

  • Page 12: Amplification

    Amplification When an amplifier is unable to fulfill your loudspeakers demands, a damaging harmonic spike may be leaked to the high frequency drivers. Another important point regarding loudness is that the dB scale is a logarithmic one. This means that a 150 Watt amplifier will potentially sound only twice as loud as a 15 Watt amplifier.

    Power up the processor next via the rear panel switch, and finally rock the I/O switch on the rear panel of the Aeris to the “I” position to turn on the internal amplifiers. Note that these amplifiers are green compliant, idling at a few watts.

  • Page 15: Wavelaunch Processor

    Wave Launch Processor The high definition Digital Wavelaunch Processor hosts a LEGACY custom algorithm which automatically loads when the proc- essor is powered on. Factory settings are ‘plug and play’, and do not require a computer to utilize. Connections between the preamp, power amplifier, and speakers should be as shown on previous page.
  • Page 16 Wave Launch Processor Downloading and Installing the XConsole software Downloading From Included CD Your Wave Launch Processor will come with a CD or USB drive containing the XConsole software. Insert the CD and find the install file. Move/Save the install file to your computer.
  • Page 17 Wave Launch Processor The XP processor will allow you to make adjustments to your system from a laptop computer from your listener position. Connecting Your Computer with the XP-4080 Processor - Connecting will require a long USB Device cable. These can be found at most electronic or big box stores. It is the same cable that a USB printer would use.
  • Page 18 Wave Launch Processor - Go back to the XConsole software. At the top of the screen click “Setup” then “Port Connections” This bring up a new dialog box. Select the COM port number you obtained from the device manger and click “OK.” The software will warn you that you must restart the software for your changes to take effect.
  • Page 19 Wave Launch Processor Making Adjustments with Wavelaunch Processor After installing the included software, connect the processor to the computer via a USB cable. Launch the XConsole software. When asked if you want to connect to the device, click yes. In the Device List, click on the device that is connected. This will launch the program that is currently on the processor.
  • Page 20 Wave Launch Processor In the Device List, click on the device that is connected. This will launch the program that is currently on the processor. Adjustments to the processor can be made to “Input 1: Left” and “Input 2: Right”. Clicking on “In 1: Left”...
  • Page 21 Wave Launch Processor Making a boost with the parametric EQ In this example, we have selected Parametric EQ 2 (PEQ2) by clicking in its box, which will turn red to indicate your selection. Once highlighted, locate the blue boxes with up and down arrows, at the bottom of the interface. These arrows are used to in- crease or decrease the gain, frequency and Q of the selected parametric EQ.
  • Page 22 Wave Launch Processor Making a cut with the graphic EQ In this example, we have selected Graphic EQ 8 by clicking in its box which will turn red to indicate your selection. Once high- lighted, locate the blue boxes with up and down arrows, at the bottom of the interface. These arrows are used to increase or de- crease the gain of the selected graphic EQ.
  • Page 23 Wave Launch Processor Adjusting using the EQ plot Adjustments made to both the parametric and graphic EQ are reflected in the graph occupying the upper portion of the screen. You can select them by clicking on their number, and dragging up to boost, and down to cut. Dragging to the left decreases the frequency, while dragging to the right increases the frequency.

  • Page 24: Continuing The Pursuit Of Perfection

    Continuing the Pursuit of Perfection (Legacy Air Motion Ribbons) LEGACY Audio has been benefiting from low mass ribbon and leaf drivers since 1984. I have a col- lection of ribbon tweeters from the world over and always loved the way good ribbons reproduced the swishing sound of brushes on a snare- and the simple honesty in the reproduction of strings without imparting an edgy ringing effect found in most tweeters.
  • Page 25 (Legacy Air Motion Ribbons) The recent Aeris loudspeaker development gave me the opportunity to tool a new AMT folded ribbon tweeter to integrate with the smoothest high efficiency 8” midrange built to date. I have yet to find a driver to challenge it. This silky 8” mid has a range of 7 octaves with nary a wrinkle in the response, yet a sensitivity of 98 dB.
