Check Applicable Products and Categories for details. Pair Your Devices Note: The procedure to listen to music from an Near Field Communication (NFC™) connection varies depending on the mobile device. Not all mobile devices are equipped with the NFC function. To see if your mobile device is compatible with the NFC function , check the mobile device's manual. 1. Unlock your mobile device screen. 2. Enable the NFC function of the mobile device. Note: For more information on how to turn on the NFC function of the mobile device, refer to the operating instructions of the mobile device. 3. Hold the mobile device close to the N-Mark on the unit, until the mobile device vibrates or plays a short sound. o Examples of the N-Mark location on your units.

A Quick Guide in Understanding Digital Audio If you're confused with some languages used to describe audio equipment, here's a quick guide to help you with some of the common terms and settings. How Digital Audio is Recorded Since real-world sound varies continuously, digital recording is always an approximation of the full range of sound in the world. However, advances in recording technology constantly expand the range and accuracy of what can be recorded digitally. When a digital recording is made from an analogue source, such as a live concert or musicians in a recording studio, the sound is sampled at regular intervals. The amplitude of the sound is recorded as a number, and this creates a digital record of the analogue audio source as a series of discrete numbers. How much of the original analogue sound is captured by the digital recording depends mainly on the sampling rate and the bit depth. How to Save and Store Digital Audio Once a digital recording is made, you can store it in a number of different formats. Each format has a different way to balance sound quality with the size of the digital file created, and extremely high quality recordings haven't historically been practical in small music players. However, as digital storage becomes more easily available with portable devices, it will boast gigabytes of storage space. As a result, high-quality digital audio is becoming a practical reality for millions of people. 5.1ch 5.1ch is short for 5.1 channels. This is a way to provide surround sound a theater-like experience. Five speakers plus a subwoofer are positioned around the listener, with each receiving a different channel as follows: Two front channels One front center channel Two surround channels One Low Frequency Effects (LFE) channel Note: The subwoofer, which receives the LFE channel can be placed anywhere in the room. Compared to a surround sound system without a subwoofer, this saves space because all the low frequencies are sent to the subwoofer. The other speakers can be smaller as they don't need to produce bass. 7.1ch A 7.1 channel surround sound system uses seven speakers, plus a subwoofer. It is similar to a 5.1ch system but with two additional surround channels. Analogue An analogue recording stores the original sound, which makes changes to a physical medium, such as a magnetic tape, or vinyl record. This is a different to the way a digital recording is made. Bit Depth The bit depth of a digital recording describes how many digits are used to store each sample of the analogue signal. The standard bit depth for CD audio is 16, with a sampling rate of 44.1kHz. This means that 44,100 samples per second are taken and each sample stores 16 bits of information. In general, a higher bit depth means greater sound quality, but also a larger file size. Note: Hi-Res Audio has a bit depth of at least 24 bits, with a sampling rate of 96kHz or above. Codec Sound or audio signal digitally passes through a coder or decoder, or codec for short. Codec is a piece of software or hardware that takes the analogue sound signal, and codes it into a digital format that can be stored electronically. When the audio is played back, the codec decodes the digital file and produce sound. Note: Each audio codec uses a different method to encode the analogue signal, so they have different benefits and drawbacks when it comes to storing and reproducing sound. Compression Making a digital audio recording can lead to very large file sizes, which limits the practical uses of the technology. For example, how many songs a digital music player can store. For this reason, most audio file formats use some form of compression, stripping out certain sound information to reduce the size of the stored file. Note: The way that sound is compressed and decompressed when played back affects the final sound you hear. File formats where information is lost are called Lossy. File formats that keep all the sound information or allow it to be reconstructed when played are called Lossless. Digital Unlike an analogue recording, a digital recording changes the sound into a string of numbers that can be stored electronically. For example on a CD or hard drive, and then converted back to sound when played. MP3 is a popular digital file format. Dolby® Digital Dolby Digital is a standard Lossy audio format used for DVD, and as a basic format for Blu-ray. Although it is a lossy format, it is still good enough for use in cinemas. Compared to DTS® Digital Surround, the sound quality is lower. The higher compression rate also means files are smaller, and so Dolby Digital is more widely used. Dolby® TrueHD Dolby TrueHD is a Lossless audio compression format similar to DTS® HD Master Audio. Both are used as optional sound formats for Blu-ray Disc. Direct Stream Digital (DSD) DSD is a digital recording method with an extremely high sampling rate, beyond that of Hi-Res Audio and 64-128 times higher than CD audio. For some sound engineers, this is as close as a digital file can get to the original analogue source. Some Sony® Hi-Res Audio products are also capable of playing DSD format audio. Digital Sound Enhancement Engine (DSEE) HX DSEE HX is Sony's unique Upscaling technology. When digital audio in a compressed format is played back, DSEE HX replaces lost high frequencies in real time, which produces a near high- resolution sound quality. All audio played on DSEE HX equipment is enhanced, which makes you feel as if you're really there at the recording studio or concert. DTS Digital Surround A standard lossy audio format used for DVD, and as a basic format for Blu-ray. Compared to Dolby Digital DTS Digital Surround has better sound quality, but it is less widely used because it produces larger files. DTS HD Master Audio A Lossless audio compression format similar to Dolby TrueHD. Both are used as optional sound formats for Blu-ray Disc. DTS:X DTS:X is a surround-sound audio format designed to compete with Dolby Atmos format. It is an immersive audio standard, created to let you feel closer to the action with the help of Height Channels, providing an effective visualization seeming to surround the audience, so that they can feel completely involved. Hi-Res Audio High Resolution Audio typically refers to digital recordings with a sample rate of 96kHz / 24 bits or above. This gives sound quality that is much higher than that of CD or MP3 recordings – the standard CD audio format is sampled at 44.1 kHz / 16 bits. When you see the Hi-Res Audio logo on a Sony product, you know that product has been designed to maximize the sound performance of High Resolution Audio. From portable music players to headphones, speakers and full home cinema systems, you can set up a full Sony Hi- Res Audio system. LDAC LDAC is an audio Codec from Sony that allows you to enjoy high-quality wireless audio over a Bluetooth® connection. When audio is transmitted over Bluetooth, it normally uses the standard Bluetooth SBC codec, which can result in a loss of quality. LDAC transmits three times as much data as the SBC codec, maintaining high quality audio over Bluetooth and giving you an enhanced wireless listening experience for all your music. Note: A separate article about LDAC is available. LFE LFE channel is a separate audio track used for low-pitched sounds of between 3Hz and 120Hz – such as low, rumbling sound effects in film soundtracks. In a surround sound system this channel is usually sent to the subwoofer.
