The Legacy VALOR system is designed to afford maximum flexibility in seating arrangements and yield a large listening sweet spot by preserving directional cues and eliminating unwanted room sound. The Legacy Wavelet, included with VALOR, allows the speakers to operate in a variety of different positions and room setups. Assuming a listening distance of about 10-12 feet, begin by placing the speakers about 10 feet or more apart and 1-3 feet from the wall behind them. A slight toe-in is recommended. Because of the unique room correction abilities of the 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.

Speaker Placement

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 Ωs/ft pF/ft µH/ft 12 ga. 0.0033 24 0.21 14 ga. 0.0048 17 0.13 16 ga. 0.0079 16 0.18 18 ga. 0.0128 28 0.21
Capacitance is considered insignificant in each cable because its ef­fect is well out of the audio bandwidth; inductance can be de­creased (at the expense of increased capacitance) by keeping the conductor pair closely spaced.
How long would a cable have to be before inductance effects would impinge on the audio spectrum? Approximately 300 feet of 12 gauge would be required to establish a corner frequency of 20 kHz with an 8 Ohm loudspeaker. As you see, inductance is not a problem for most of us.
9 of 50
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.
What about resistance? Finally we are getting somewhere. Resistance is the control­ling factor of the amplifier/loudspeaker interface. Excessive resistance can cause ma­jor shifts of speaker crossover frequencies. The lower the impedance of the loud­speaker, the greater the effects of series resistance. A 20 foot run of 18 gauge cable can cause up to 10% deviations of crossover center frequencies. That same 20 feet can un-damp your damping factor and reduce your systems’ output by onehalf deci­bel.
In summary, there are no perfect cables. The best way to approximate the ideal would be to keep loudspeaker leads as short as is practical.

Amplification
Ideally the loudspeaker would be among the first components selected when assembling a play­back system. This would allow the user to choose an amplifier capable of delivering adequate amounts of current into the frequency dependent load presented by the loudspeaker. However, when upgrading a system, audiophiles may find themselves matching their new loudspeakers to their existing 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 under­stood that the role of the amplifier goes beyond that of driving loudspeakers to a given sound pressure level. The amplifier should be able to CONTROL the loudspeakers across the entire mu­sic spectrum. This means that parameters such as damping factor (values greater than 60 are acceptable) and dynamic headroom should not be overlooked when comparing amplifiers.
11 of 50
Amplification
How much power will your new speakers need? That ultimately depends on your listening environment and musical tastes. As little as five watts per channel should drive them to a level satisfactory for background music. A typical 45 watt per channel receiver may fill a room with the compressed mid-band energy of “heavy metal,” but seem to lack weight or control with classical recordings. 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 advan­tage of “high-powered” amplifiers, so don’t be afraid to put them through their paces.
How much is too much power? Rarely is a drive unit damaged by large doses of music power. More often than not the villain is amplifier clipping distortion. Even through decades of refinement, loudspeakers are still noto­riously inefficient transducers, requiring huge amounts of power to recreate the impact of the live performance. Typically less that 1% of electrical power is converted into acoustic output. (For example, an omnidirectional transducer with an anechoic sensitivity of 90 dB @ 1w/1m has a full space efficiency of only 0.63%)
12 of 50
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. If all of this discussion of power and loudness seems a bit abstract, consider the example below.
The average acoustical power developed by a person speaking in a conversational tone corresponds to a mere 0.00001 Watts. The power that would be developed by the entire population of the city of New York speaking at once would barely illuminate a single 100 Watt light bulb.
The standard VALOR system provides four channels of amplification internally for the subwoofers, bass drivers, midwoofer and ambient array. You will need to supply one channel of amplification of 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.
1 Left speaker subwoofer amplifier (internal 1000 watts)
2 Left speaker bass (internal 750 watts)
3 Left speaker midwoofer (internal 500 watts)
4 Left midrange/tweeters amplifier (user provided)
5 Right speaker subwoofer amplifier (internal 1000 watts)
6 Right speaker bass (internal 750 watts)

Behind
with Chief Designer,
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. The central 14" is a coaxial from Italy where a 2" polyester/titanium HF driver sets in a precision machined aluminum throat that aligns output within the 3.5" voice coil of the woofer. Placement is dead center of the triple 14" driver array where a horizontal bridge with a central lens splays a pair of 4" AMT super tweeters. The drivers' output angles trade off intensity to maintain uniform output with varying listener positions.
The two 12" subs, front and bottom loaded are hefty dual voice-coil units with aluminum cones and 30 lb. motor structures. The two 12" passives are on the rear of the cabinets and utilize a patented dual symmetric suspension and a damped diaphragm with 4" peak to peak travel.

Time vs. Phase
Music Reproduction: It’s all in the Timing
The stereo effect is a fragile illusion based on the interference of the acoustic arrivals at the left and right ear. Timing and amplitude differences over the audible frequency bandwidth for the arrival to each ear is the basis of the head related transfer function (HRTF).
The brain has an uncanny ability to process and triangulate acoustic source locations from these combined arrivals. However, this is not the only way that we localize sounds. In fact, completely covering one ear does not prevent you from localizing sound. Give it a shot.
However, the perception of sound from only one ear will radically reduce one’s ability to the map out the acoustic environment and will make speech seemingly less articulate in even a moderately reverberant environment. It is key to have sound arrive to both ears for the brain to selectively focus on a source and while working to subjectively reduce the masking background noise.
16 of 50
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. However, put on a set of headphones and flip polarity on one channel and you might be in for a surprise. You might logically expect the bass to become thin or weak. But the brain does not process this phase difference in the way that you might think when the waveforms have not interfered acoustically. No audible comb filtering is introduced.
Another noteworthy aspect of phase, timing and polarity is you cannot compensate a time delay with any amount of phase shift. Time delay represents an infinite number of phase shifts at an infinite range of frequencies. Similarly, a waveform cannot be truly out of phase unless it’s a single frequency (think sine or cosine wave). Therefore, the terms “reverse polarity” and “180 degrees out of phase” are not interchangeable when discussing music waveforms.
Proper understanding of the time domain finds that equalization introduces time smear .
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. The diffuse energy of the recording environment is shown isolated on the axis pointing right. Observe that for each instant there is a unique tail of reverberant information for this recording channel.
STEREO UNFOLD separates the diffuse energy of each stereo channel and restores it to the natural level and time relationship within the particular listening room. This allows the direct energy to be articulated more clearly and the directional
vectors to be analyzed by the brain as matrixed in the left, right arrivals.
New STEREO UNFOLD TechnologyTM advances the art of music reproduction by restoring the natural timing and level relationships of direct and late arrivals. The spectral balance of ambient information is returned to a natural level while early reflections that cloud spatial information are minimized. This is made possible by first reducing the masking effect the listening room has on the actual recording environment by applying the Bohmer Room Correction which realigns acoustic arrivals to the listeners in the time domain. STEREO UNFOLD Technology then examines and identifies the related ambient components following the initial wave-front and restores this diffuse field information to the proper level in your listening room.

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 unbalanced RCA inputs without concern of digital artifacts. An apodizing circuit corrects for the pre-ringing native to CODECs. Wavelet has adequate headroom to handle these higher level signals while functioning as a crossover and compensating for room resonances. Wavelet processes at 56 bits of depth in a domain more than one trillion times finer in resolution than that of a 16 bit CD.
The Wavelet is by design upgradable. The unit can download firmware updates directly when you choose.
While the Wavelet offers high quality/ low noise balanced inputs to accept the analog output from any SACD player, ideally one would instead stream PCM versions of these files to the processor via the USB input. Within software such as J-River, the 1 bit DSD is converted to 64 bit PCM at 1/8 the sample rate. The total amount of data from this conversion grows by 8x, so the process is effectively lossless / perfect. The conversion is necessary as DSD is inefficient for sophisticated DSP operations.
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. Once you have PCM, it will be 64bit @ 352.8 kHz for DSD, and 64bit @ 705.6 kHz for DSD 2x. The option 'Greater than 192kHz' in DSP Studio > Output Format should be selected.
Why PCM? This is a format issue and has nothing to do with the Wavelet in particular. As professional studios rely on PCM based equipment such as Pro Tools to mix, pan and balance recordings, the vast majority of SACDs are in fact mixed in PCM, or mixed analog and recorded in PCM. They may then be converted to DSD for SACD mastering stages. The PCM format is far more efficient where DSP is in use. Recently a newer studio format, DSD­wide, has been developed to allow DSP operations that can be down-converted to DSD for SACD production. Pro DAWs such as SADiE are now using this technology.
PCM is the universal format of studios and digital signal processing. Most recordings released in other formats were actually recorded in PCM format.

The Bohmer Correction is a loudspeaker in-room energy-time alignment that optimizes the loudspeaker room acoustic transfer function in both frequency and predominantly time domain. Working with revolutionary new algorithms is starts with a psychoacoustically based measurement method. Alignment errors are then optimized individually, not resorting to the common crude bulk correction over the entire frequency spectra. The Algorithms use psycho acoustic reasoning for alignment and correction of the loudspeaker room transfer function. The correction improves sound quality in the whole room, provides improved transient response, clarity & soundstaging and gives a relaxed sound without rough edges or any booming.

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.
Outboard DAC to Wavelet Analog Inputs Using Wavelet as your Preamplifier
The Wavelet has adequate internal gain for virtually any outboard DAC ouput. In some cases you may wish to decrease the input sensitivity of the Wavelet to accommodate an external DAC with high output level, especially if your are using one with a volume control. Each stereo pair of analog inputs of the Wavelet can be adjusted downward in -3, - 6, or -12dB steps as shown below. The goal is to set the analog channel’s input sensitivity so that adequate volume level is achieved from your system without any audible clipping of the
inputs. When adjusted properly, the Wavelet’s blue front panel display will usually be in the range of 85dB for average listening levels. When using the Wavelet’s digital inputs such as the SPDIF from a CD transport,
adjustments are not required - thus there are no provisions for such. Some computer hosted media software may introduce an extra level control stage to the USB output. In this case it is best to configure the software settings so a typical listening level is accomplished with Wavelet displaying 85dB.
Outboard Preamp Driving Analog Inputs Using Wavelet for Crossover/Room Correction
If you are relying on an external preamplifier to provide the both the master gain and level control into the
Wavelet, you will need to optimize the inputs sensitivity of the Wavelet’s analog inputs. The key is be certain
that the highest volume from the preamp does not overload the analog inputs. We recommend beginning
with the -12dB setting initially as shown below. Further attenuation of -3, -6dB is available if needed. While
25 of 50
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. Rarely does the Wavelet need to be set above 90dB when optimizing to the volume settings familiar from your preamplifier.

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.
Individual tonal preferences can vary with mastering engineers as well as listener preference. For this reason it is great to have the flexible control over voicing of the playback system that Wavelet provides. The Wavelet's carefully designed contour controls allow gentle response shelving without phasiness or ringing.
Brilliance: controls the "air" and definition of a recording above 10kHz
Low-Treble: adjusts the brightness or forwardness above 3kHz
Upper-Bass: adjusts the fullness or bloom of vocals, cello, etc. below 300 Hz
Mid-Bass: determines the apparent speed of decay of bass frequencies.
Reducing will tighten, slight boosts will warm below 150 Hz
Low-Bass: adjusts the overall weight or heaviness below 75 Hz
Punch: controls the drive or impact felt from the rhythm at 55 Hz
TIPS
1. Try a boost of +2.5 dB in the brilliance, a low treble setting of -0.5 dB, a low-bass setting of +2 dB with the punch slider set at +2.5 dB. Now adjust mid-bass by ear until it seems most natural without excessive thickness.
2. Want a tube-like warmth? Manually increase the output on channels 2 and 6 by 1.2 dB and then trim the brilliance contour to -1.0 dB. Fine tune the depth by adjusting the low-treble contour.
The most recent slider settings are retained permanently in the Wavelet memory- even if you turn the unit off, Wavelet will remember your settings.
You can also adjust the output levels of the individual channels.

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.
The level controls are also useful for later tweaking subwoofer weight for home theater and adjusting the ambience level as desired.

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.
4 pairs of stereo analog inputs allow Wavelet to easily interface with your preamplifier, transport or other devices- making it both flexible and letting you retain all of the color you might enjoy from your gear- tube, solid state or digital.

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”
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. Turn on the apodization circuit by choosing “Settings” at the top, clicking “DAC” and selecting “Apodizing”. “Linear” bypasses the apodization circuit.
Updating the Wavelet System

Wavelet is, by design, easily updated via the app. This allows the device to be updated with new added features as they are developed.
To check for updates, choose “Settings” at the top, select “System update” and click “Check for update”

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. You can disengage Stereo Unfold by
choosing "Standard" to compare the difference.

-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).
Achieving Ideal Imaging In The Room
44 of 50
Below about 1500Hz there is a phase difference between the sound waves entering the ears, thus providing acoustic localization cues (interaural time differences, or ITD). At frequencies greater than 1500 Hz, the wavelength is shorter than the distance between the 2 ears, and phase sensitivity diminishes. The brain now relies on acoustic head shadows produced across the face to provide level
differences to each ear (ILD) and cues for the localization of this sound. If the speaker system projects sound onto the room boundaries creating a diffuse field before it can reach the listener directly, these fragile ITD and ILD cues will be altered and scrambled.
The key to imaging is preserving the interaural time and level differences. The shadowing to the far ear from the source is quite fragile in a reflective environment. 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.

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. This reflected energy is out of sync with the original signal.
A few milliseconds later, the first wave-front is about to reach the listener, while the reflected energy is close behind. These early reflections alter the original tonal balance. As they occur within the fusion time window, the brain cannot separate the sounds.
After less than 1/100th of a second, the room has
46 of 50
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.
The listener will perceive this reflection as additional bass energy, though a standing wave has not had time to develop.
It is a common misconception that such low frequency excess energy is merely the result of inevitable resonances within the room, when a large portion can be attributed to initial reflections.

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. Below right is the same wavelet plot with the Bohmer correction method.
