Page 5: The Cabinetry / Our Commitment
Our Commitment A great deal of forethought, love and satisfaction is instilled in each piece of Legacy workmanship. We take pride in getting to know many of our customers on a first name basis.
Page 6: Warranty
Warranty Legacy Audio supports its customers and products with pride. We cheerfully warrant our loud- speaker products we manufacture from defects in materials and workmanship for a period of seven (7) years. Electronic components such as internal amplifiers and digital processors are covered for three (3)years.
Page 7: Placement
VALOR system, adhering to the exact recommended placement guidelines is not as critical as it is with conventional speaker systems. Your dealer and Legacy Audio will be able to look at your room setup and recommend the best positioning for your VALOR system.
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 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.
Page 13: Speaker Connections
60 watts or greater, for the midrange and tweeter section of each speaker. VALOR can be built with internal amplification for the entire speaker, or with fewer internal amplifiers - should the listener prefer to use external amps. Three professional grade 15 foot balanced XLR cables are provided for each speaker.

Page 15: Behind The Design
Chief Designer, Bill Dudleston Much like a directional microphone the VALOR's output is carefully shaped into a cardioid pattern to reduce early reflections to side and rear. This sculpting occurs as two of the 14" dipolar 'open air' drivers acoustically combine with a third closed back driver.
Page 16 Time vs. Phase There are some often misunderstood aspects of phase, polarity and time. We know we can hear the acoustic cancellations and summations that occur when soundwaves interfere in space on the path to our ears. This interference introduces frequency response changes.
Page 17: Stereo Unfold Methodology
Stereo Unfold Methodology The 3D measurement below allows us to view how a particular transient (in this case a simple clap of hands) decays over time within the recording environment. Shown on the axis pointing left is the composite energy that is the direct plus diffuse energy.
Page 18: Specifications
Application: Sequential sound field reconstruction system, auto-setup with calibrated microphone Specifications System Type: 8 Driver, 4 way system with specialized 3 driver ambient array Tweeter: Dual 4" AMT bridge-mounted in post convergent array Midrange: 1.5" coaxial, titanium/polyester diaphragm, precision waveguide Midwoofer: 14"...
Page 19 Wavelet Wavelet is a control preamp, a premium DAC, a digital crossover with time alignment for each driver section and an acoustic correction system that will literally ‘learn’ your room. True digital flexibility SPDIF (opticalTosLink, coaxial): up to 96kHz/24bit USB: All file formats up to 96kHz/24bit are sent directly from the PC to the Wavelet without any conversion. Higher resolution files such as PCM and DXD can be readily played back using software such as J-River (select: Greater than 192kHz under DSP STUDIO.) Analog Friendly Already have a favorite DAC with a volume control? How about a big vinyl collection? Analog lovers can take advantage of balanced XLR or...
Page 20 In the J-River software this configuration is located in the Player -> DSP Studio - Output Format section. Setup all sample rates up to and including 96kHz to “No Change”. Then set input 176,400 to output 88,000, 192,000 to 96,000 and greater than 192,000 to 96,000. DSD is converted automatically in the software to PCM.
Page 21 Inside the Wavelet processor carton packaging you’ll find a hard-case containing a measurement microphone, a 25 ft. XLR cable and a mic calibration plot. At the opposite end of the carton you will find a power supply with a five pin locking connector and its 115 V AC cable, a compact remote volume control, a Wi-Pi network connector and a SanDisk USB memory stick.
Page 22 Wavelet Preamplifier/DAC/Crossover/Room Correction Processor Inputs Analog  Two pairs of Stereo balanced inputs on XLR connectors. Input sensitivity without attenuation 0 dBFS = 1 dBV , input impedance 20 kOhm. Analog attenuation available in three steps of -3 dB, -6 dB and -12 dB for an input sensitivity of respectively 0 dBFS = 4 dBV, 7 dBV or 12dBV. ...
Page 23 Outputs Analog  8 balanced output channles on 8 XLR connectors. 0 dBFS = 8 dBV , 33 Ohm output impedance. An analog output level increase of 6 dB is available through internal jumpers offering 0 dBFS = 14 dBV ...
Page 24 Optimizing Analog Outputs When using the analog inputs it is useful to optimize the input levels according to how they are being used. This will maximize the signal to noise ratio and provide optimal gain while preventing distortion from input overload.
Page 25 with the -12dB setting initially as shown below. Further attenuation of -3, -6dB is available if needed. While you can also further reduce the volume setting from your preamp, the goal is totally avoid clipping at all levels. Again try to establish a Wavelet level setting of about 85dB for typical listening. With a little care you will have minimized your noise floor and prevented input saturation.

Access this page by clicking “Settings” and choosing “Contour”. -Settings -Contour...
Page 36 The sliders can be adjusted in the same way as the volume control- by placing a finger on the center slider. Moving to the right creates a boost (more volume) and moving to the left creates a cut (less volume) in the given frequency band. A handy “Reset Sliders” button is available at the bottom to reset the Contour Sliders.
Page 37 You can also adjust the output levels of the individual channels. -Settings -Setup -Manual channel level adjustments Subwoofer Output Level Midbass/Lower Midrange Output Level Upper Midrange/Tweeter Output Level SUT Ambient Array Output Level The channel level controls can be used to compensate for amplifier gain differences up to 18dB. One can approximate the level setting by ear and then allow room correction to fine tune the response.
Page 38 Input Selections You can wirelessly switch between inputs on your Wavelet by selecting “Input” at the top and choosing your desired source. USB allows Wavelet to connect to a computer and play back high resolution audio. USB, SPDIF and Toslink allow for digital connectivity and reduces the need for an extra AD conversion- a valuable performance advantage.
Page 39 Mode & DAC Adjustments Wavelet allows you to listen in Stereo, Mono and Inverted modes. You can access these settings by choosing “Settings” at the top and selecting “Mode” -Settings -Settings -Mode -DAC The Wavelet features an apodizing circuit that corrects for the pre-ringing native to CODECs. Analog lovers can take advantage of balanced XLR or unbalanced RCA inputs without concern of digital artifacts.

To check for updates, choose “Settings” at the top, select “System update” and click “Check for update” -Settings -System update If an update is available, you can click “Download and install update”.
Page 41 -Presets Wavelet with Valor features Stereo Unfold technology that can be activated by clicking Presets and choosing "Restored." SUT works by unmasking the material that is already in the recording (wether it is an analog or digital signal). It does not add anything to the material- instead it allows your ear to hear more of the information that already exists in the recording.
Page 42 Updating the Wavelet System To adjust the brightness on the front panel of your Wavelet, choose “Settings” at the top, select “Front panel" and adjust the slider left or right. -Settings - Front panel At power on the startup volume is set to a default value, usually 60. If you would like Wavelet to recall the last volume level you listened at before turning the power off, please switch "Startup volume"...
Page 43 -Settings -Home theater mode Wavelet can be easily used in a home theater (and simultaneously a 2 channel) system, and you can take advantage of the Wavelet's room correction for your left and right speakers in your home theater system, just like you do during stereo playback. Turning Home Theater Mode on will bypass the Wavelet volume and allow you to control the overall volume of your surround sound system from your receiver (or preamplifier).
Page 44: Imaging & Room Correction
Maintaining directivity in the speaker radiation pattern is essential to preserve this content. Legacy 's VALOR, V, Whisper, and Aeris designs each offer unique directivity control to provide greater clarity, better localization and resonance reduction.
Page 45 Why is Room Correction Necessary? To the left is a 2 dimensional simulation of a 1ms wave pulse from a pair of conventional speakers into a room similar to the above. Because the dispersion exceeds 60 degrees, undesirable energy from each speaker is reflected back into the room within a few thousandths of a second.
Page 46 After less than 1/100 of a second, the room has developed a complex wave pattern with energy varying with room position. The listener is now awash in a series of wave-fronts which will soon reflect off the wall behind. A mere 5 milliseconds later, the initial direct wave-front has now reflected off the rear wall and has made its way back to the listener.
Page 47 To the right is the irregular frequency response of a speaker on axis in the presence of room boundaries. The smoothed curve is the result of applying conventional room correction methods. Below left is the impact of the correction on the Fequency-Time domain.
