As a new product of the company's "Walkman", Sony is a flagship model "NW-WM1ZM2" that supports music streaming services and further improves sound quality by adopting Android OS, and "NW-WM1AM2" from March 25. Release. [Photo] In the past, the price is open for both large-scale display size, but in the market, NW-WM1ZM2 is expected to sell at around 400,000 yen including tax and NW-WM1AM2 is around 160,000 yen including tax. Walkman's new top model, which is the successor to the "NW-WM1Z" and "NW-WM1A" released in 2016. The difference between the two models is the housing material, the built-in storage capacity, and some recruitment parts, the NW-WM1ZM2 has a built-in storage of 256GB in an oxygen-free bronze housing, and the NW-WM1AM2 has an aluminum cut-off and 128GB of storage. Built -in. The details of each model will be described later. ■ While supporting the music streaming service, both models pursuing the high -quality design are equipped with Android OS (Android 11) instead of Linux -based OS used by the conventional model. In addition, by supporting Wi-Fi, various apps such as music / video streaming services can be installed from Google Play. GPS is not installed in consideration of the impact on sound quality, and does not support apps that require a GPS function. At the same time, the inside of the housing has thoroughly designed the highest priority on sound quality, achieving even higher sound quality. As an example, digital block / antenna module and analog blocks are firmly separated and placed to prevent mutual interference. The digital block is attached to the cut -free copper shield, so that noise is shielded, and the ground is stabilized to reduce noise. In addition, the power supply was enhanced. The bypass condenser uses a proprietary polymer condenser "FTCAP3". The "FTCAP2" mounted on the digital audio player "DMP-Z1" has been further improved, and the latest generation condenser with enhanced vibration resistance has improved the size of sound clearness and sound field. Purification 99 for a power cable that connects the battery.96 % of OFCs are adopted, and the battery itself is larger than the conventional model. In addition to improving the growth of the high range and the sinking of the low range, the continuous playback time has been enhanced to about 40 hours (FLAC 96kHz/24bit). In addition, in the joints of all parts, we use a unique high -quality solder that adds gold. In the past, the model was used only for the part that performs the torn on the handle, but in this model, the use of all the joints has greatly increased the spread of sounds and a sense of position. A new ultra -low phase noise crystal oscillator is also used for the digital clock. It is said that the internal electrode is not a general silver plating but a gold plating, which has improved the separation of instruments and the amount of bass volume. ■ Equipped with a full digital amplifier "S-Master HX (CXD3778GF)", which is equipped with "DSEE ULTIMATE" and "DSD Remastering Engine" that expands how to enjoy music. PCM 384kHz/32bit, DSD 11.Supports 2MHz native playback.Headphone terminal is also 3.5mm imbalance / 4.Equipped with two types of 4mm balance, the maximum practical output is 60MW + 60mW (16Ω), and the balance connection is 250mW + 250mW (16Ω).The "DSEE" function to upload non -high -resolution sound sources is updated to the latest version "DSEE ULTIMATE".Sampling frequency and bit depth are expanded to up to 192kHz/32bit.By automatically determining the type of song by AI technology, it also improves the expressive power of the high range such as female vocals, and the reproducibility of the fine sounds such as the growth and disappearance of the stringed instrument.In this model, DSEE ULTIMATE is now available even when music playback in other companies' apps such as streaming services and when connecting Bluetooth headphones / earphones.In addition, a Loss Codec equivalent to CD (FLAC 44).It has evolved upscaling technology in 1kHz and 48kHz).For the first time as a Walkman, it was equipped with a "DSD remastering engine" that was also used in DMP-Z1.It is a function that converts the original data to a DSD signal without impairing the original algorithm, and is more than DMP-Z1 in this model..Compatible with conversion equivalent to 2MHz.It is also possible to switch on / off according to the taste of the sound quality.This function is a wired connection and "w".Only music playback in the Music app is supported.In terms of operation, the display is the conventional model 4.0 inches to 5.Large screen to 0 inch (1,280 x 720).The UI of the home screen and the playback screen has been renewed, and the playback application "w."Music" can be displayed as widgets.In addition, the background of the playback screen changes according to the jacket color of the music during the playback."W.Music is equipped with an "aging counter" that records the playback time of each balance / unbalanced connection. This model recommends 200 hours of aging for balance / unbalanced connections in order to stabilize the characteristics of the condenser and bring out the maximum sound quality, and you can always check the situation. In terms of functions, the "DC linear riser" that continues to the characteristics of analog amplifiers, the "Vinal processor" that reproduces the texture of the analog playback, the "dynamic no marriser" that matches the volume difference for each song, and the equalizer. Equipped with such functions. It supports the USB-DAC function, but has not been equipped with the tone control function. It also supported the playback of 360 Reality Audio, a three -dimensional sound. For data transfer and charging terminals, USB Type-C (USB 3 (USB 3) instead of conventional WM-Port..2 Gen1) was adopted.Charging as well as data transfer, 80 % in about 3 hours, about 4.Completely charged is possible in 5 hours.Bluetooth codecs are newly supported by the conventional LDAC/aptX HD/aptX/SBC.On the other hand, NFC and Bluetooth receiver function are not installed.In addition, the CD drive "CD Reco" of I -O data was connected to support the direct CD ripping to the main unit.The external dimensions are about 75 for both models.6W x H141.4H x 20.8Dmm, the mass is about 490g for NW-WM1ZM2, and about 299g for NW-WM1AM2.As an accessory, a USB Type-C cable (USB-A-USB-C) and headphone terminal caps (stereo mini/balance standard) are included.In addition, as an optional option, the special leather case "CKL-NWWM1M2" will be released at the same time from March 25.Although the price is open, it is expected that the actual sale is around 11,000 yen including tax.A structure that does not hinder the operation of the side button while protecting the surface of the walkman from scratches and dirt.In addition, as a point of improvement from the conventional model cover, it was firmly covered to the side of the main unit, and it was possible to charge with the cover attached.■ As described above, NW-WM1ZM2 and NW-WM1AM2 are the main differences in the housing material / internal storage capacity / part of the parts.NW-WM1ZM2 is a purity of about 99 with anoxic-free copper that is cut out..Anoxic -free copper gold plating chassis with 7 % high purity gold plating is adopted.By combining a very low resistance value and a gold plating that reduces contact resistance and preventing oxidation, it is both a clear high -pitched and clear and powerful low -tone range.It is said that it has achieved excellent expression in air and lingering.Furthermore, the oxygen-free copper of the chassis is higher pure than the conventional model NW-WM1Z..99 % (4N) is adopted. According to the company, the difference in the purity of the anaerobic chopped chassis has a significant effect on the sound quality, and it was necessary to tune again on the premise of adopting this material. The internal wiring that connects the amplifier to the balance output jack is a 4-core cable made of kinber cable common to DMP-Z1. NW-WM1Z also used the internal wiring made of kinber cable, but this time a large-diameter cable with the same specifications as the company's headphone cable "MUC-B20SB1". It is said to reproduce a more powerful and smooth sound quality. The rear cover on the back is made of cut -out aluminum. The NW-WM1Z had a two-piece structure that combines plastic and corson copper, but this time the rigidity has been enhanced to increase the rigidity. On the other hand, NW-WM1AM2 continues to adopt an aluminum chassis that has been cut out from the conventional model NW-WM1A. Reducing resistance and improving rigidity in a well -balanced manner. In addition, an aluminum cover with an integrated structure is adopted on the back. As with NW-WM1ZM2, a non-copper model-free copper model, it has increased rigidity.
