Thank you for purchasing the Legacy V loudspeaker system!
The Legacy V is a full range loudspeaker system utilizing the present state of the art in driver, crossover,
amplifier and acoustic radiation control technologies.
The Legacy speaker system is designed, assembled and tested in Springfield, Illinois by a dedicated group of
engineers, craftsmen and music lovers. The custom processor is designed and fabricated in Lund, Sweden
under the direction of Bohmer Audio. Please take a few moments to learn more about the features and
controls of these instruments to assure full enjoyment.

Uncrating
Each V speaker has been carefully packaged in a specially designed crate to ensure they reach you safely and undamaged.
You will find the Top, Front and Back panels labeled on each crate as well as the Left/Right speaker designation.
Screws that are to be removed will be painted black for your reference.
Unpacking Instructions:
Step 1: First remove the top panel B. Due to the height of the crate, this will likely require a step ladder.
Step 2: Once the top panel is removed, remove internal cross bracing C. There are screws located on each end of the brace.
Step 3: Next, remove the front panel Aand braces D, H.
Step 4: Then, remove the two side panels F, G.
Step 5: Finally, remove the remaining back panel E,leaving the speaker resting on the base I. Due to the substantial weight of the loudspeakers,
we suggest that at least two persons assist in removing each speaker from the base.
Step 6: Remove any additional foam/bagging. Use caution when moving to the final listening position. If a dolly is used, cover with a soft material such as a
blanket to prevent any scratches.
Note: You will find the associated top rear speaker grille bonnets, Wavelet processor unit and cables each boxed separately.

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. Also included is a micro USB cable to connect your computer or media server to the Wavelet.

Wavelet
At the heart of your V loudspeaker system is the Wavelet processor. 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, TosLink: 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
96ks to “No Change”. Then set input 176400 to output 88000, 192000 to 96000 and greater than 192000 to 96000. 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, DSD-
wide, 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.
