The pinnacle of near field listening
The SA-Z1 is meticulously crafted to sit on your desk and provide you with a reference listening experience, whatever your choice of music. Play music from your laptop or PC, hook up your Walkman or Xperia, or use with a dedicated digital music player.
Sony expertise in precision-engineered powered speakers
The SA-Z1 brings together Sony's legendary audio expertise with first-of-its-kind custom componentry and benchmark audio technologies. Thanks to a trio of accumulated acoustic, electronic and signal-processing technology, SA-Z1 recreates music with except
Coherent impulse response
Well-designed multi-way speakers have a flat and broad frequency response, but disengaging the impulse response (time-coherence) risks a compromised soundstage. Conversely, single driver units offer excellent impulse response but sacrifice frequency respo
Time coherence
The SA-Z1's multi-amplifier system and unique Field Programmable Gate Array (FPGA) perfectly synchronizes the wave front between driver units. The precisely aligned wave front and broad frequency response are capable of delivering both the power of an exp
Coaxial driver layout
For reference-quality near field listening, the SA-Z1 features a coaxial speaker layout. Combined with the FPGA for time coherence, this design offers ideal acoustic centring across the frequency range. The result is phase coherence - essential for clear
Horizontally opposed woofers, Tsuzumi' layout
Inspired by a traditional Japanese Tsuzumi' drum, dual woofers are placed back-to-back. This layout hugely cuts unwanted vibration - the vibration from each woofer cancels out the vibration from the other. By reducing the enclosure resonance so significan
Bass expansion duct
The unique Tsuzumi' design also supports wide sound dispersion. Unlike conventional speakers, the rear bass expansion duct lets bass radiate to the sides as well as forward-just like sound sources in nature-so you experience a natural, realistic sound fie
Innovative air control behind the woofer
For the SA-Z1 we developed our woofer from the ground up. Large aperture slits behind the diaphragm prevent turbulence that causes wind noise and disturbs the linear motion of the diaphragm. The breathable magnet layout is a new idea to suppress the turbu
More linearity and purity
The woofer offers supreme linearity with very low distortion. The zinc die-cast basket holds the motor system firmly so that it can suppress vibrations from piston motion. Powerful neodymium magnets preserve the linearity and the copper sleeve reduces dis
I-ARRAY™ tweeters for wider frequency and off-axis response
Sony's acclaimed I-ARRAY(TM) high-resolution tweeters combine a main tweeter with two smaller assist tweeters, for both impressive frequency extension and wider directivity. The large balanced dome main tweeter ensures excellent high-frequency realism, wh
New balanced dome tweeter unit
The balanced dome structure suppresses break-up mode-which disturbs high frequency response-so that it can reproduce 100 kHz to release the full potential of High-Resolution Audio. The voice coil drives at a point where the weight of the diaphragm and air
Titanium sputtering diaphragm
The surface of the tweeter dome is coated with titanium sputtering for lightweight rigidity and a high-velocity rise. The high internal loss reduces resonance and results in a tightly defined transient response, even at high frequencies, for natural sound
Aluminium body
Featuring body parts using two different alloys of aluminum, the SA-Z1 effectively minimizes noise distortion caused by resonance of enclosure.
FBW chassis
For the SA-Z1 we've updated our renowned frame and beam chassis with a new wall structure made from a solid aluminum block to isolate the circuit board from vibrations from the speaker. This suppresses structural resonance for a clean, uncoloured sound wi
Bridge arm structure
A precision-engineered bridge structure decouples the speaker enclosure from the amplifier and digital processing circuitry. The solid aluminum isolation links preserve sound purity for a remarkably focused and coherent presentation.
Composite enclosure structure
The enclosure of the SA-Z1 consists of six pieces of thick aluminum plate. While a monolithic enclosure is strong, it sustains resonance for a long time as a speaker enclosure. By jointing the six plates using a technique inspired by traditional Japanese
D.A. Hybrid Amplifier Circuit
Our original S-Master digital amplifier was a revolution, with its non-feedback design for pure digital sound. The D.A. Hybrid Amplifier took this one step further, enhancing precision with an analog feed-forward amp to correct digital switching errors. N
Distortion reduction
To achieve ultimate sound reproduction, S-Master HX digitally amplifies the music signal without any resulting transmission loss. However, at the final stage of amplification, the physical limits of the semiconductor unavoidably cause distortion. So, to d
Gallium Nitride
MOSFET transistors are typically used for digital amplifier switching, however they can produce ringing distortion due to slow switching speeds. By using Gallium Nitride (GaN), we can suppress the ringing through high-speed switching. This means that ampl
Error correction
The analog amplifier compares the true signal with the digital amplifier output signal, identifying the error caused by switching. Then it produces an error correction signal to restore the output signal, preserving the purity of the original sound, and r
Custom architecture on FPGA processor
Sony's engineers realized early-on that typical, off-the-shelf DSPs could never draw optimal performance from their unique D.A. Hybrid amplifier and coaxial speaker design. So they built an original architecture on an FPGA (Field Programmable Gate Array)
L/R synchronization
The OFC cable that transmits the high-speed differential signal between speakers is engineered to suppress signal reflection and loss, and to shut out interference. This ensures accurate time alignment between the left and right speakers - crucial for rep
DSD Remastering Engine by FPGA
The DSD Remastering Engine lets you convert all PCM music sources into DSD 11.2 MHz. The technology uses the FPGA to convert any signal into the DSD sound format.
New DSEE HX™ analyzes song type by AI
Audio upscaling is improved even further by our new DSEE HX(TM) processing, which intelligently recognizes instruments, voices and musical genres. By identifying these and the relative energy of the audio, it can accurately rebuild audio lost during digit
D.A. Assist
With hybrid amplification you get the best of both worlds - standard or blended sound. In the standard position, the analog amplifier works as just an error corrector. When you select the blended position, the analog amplifier starts to drive the speaker
Assist Woofer Motion
You can choose to lock the assist woofer in place, rather than using it to complement the sound of the main woofer. This adjusts the sound stage to suit your tastes, music, and listening environment. [1. Active 2. Fixed]
Assist Woofer Frequency
You can change the frequency range of Assist Woofer. The narrow position delivers a tighter bass sound. The wide position reinforces the bass sound. [1. Narrow 2. Standard 3. Wide]
Assist TW Time Alignment
You can intentionally change the time alignment between tweeters and woofers. Sync' offers you perfectly time-aligned sound. Advance' describes a clear-cut sound image by advancing sound from the tweeters ahead of the woofer. Conversely, Delay' offers a s
Supported sound formats
Support up to PCM 32 bit/768 kHz and DSD 22.4 MHz.
Interface
Analog-In connections include RCA, stereo mini, and balanced XLR. Digital inputs include USB-B, optical and micro-USB for Walkman.
