About High-Resolution Audio format files
High-Resolution Audio, which is typically 96 kHz/24 bit or higher, is made by digitally sampling an original analog audio source. The number of times at which sampling is performed (in one-second increments) is called the sampling frequency, which is expressed in hertz or Hz. Digitizing refers to the audio process where the sampled signal is converted (or quantized) into binary digits, consisting of 1s and 0s, and expressed as bits. The higher the number of bits, the closer the sample is to the original source. CDs are standardized at 44.1 kHz/16 bit, but there is no single standard for High-Resolution Audio. An alternative way of digitizing an analog source is a method called DSD (Direct Stream Digital) which captures sound information as a sequence of single bit values with an extremely high sampling rate of either 2.8 MHz or 5.6 MHz. This is approximately 64 or 128 times the sampling rate of CD audio and is simply known as DSD 2.8 MHz or DSD 5.6 MHz. For some engineers, this is the closest a digital file sample can get to an original analog source.

About the balanced connection
Unbalanced connections have commonly been used for portable audio devices. This connection method works as L+/R+ signals go through an amplifier and L-/R- signals go through the ground. Devices with unbalanced output are normally less expensive and easy to handle compared with the balanced output devices, but unbalanced connections cannot prevent noise occurrence since noise can be picked up if there is a difference in voltage potential on the ground of the chassis of your device. One of the biggest advantages of balanced connection is that it can stabilize the voltage potential by transmitting the signals as the opposite phase, L+/L- and R+/R-, to an amplifier. Not only does this prevent the signal distortion caused on the ground, but also eliminates noise and hum with opposite polarities relative to each other. As a result of this, balanced connections brings you clear sound with noiseless signals and improved crosstalk.

Installing the driver software on a Windows computer
To play back the music files on your Windows computer with the headphone amplifier, you need to download and install the driver software for Windows Sony USB Device Driver on the computer.
1. Visit the following support website, then download and install the driver software for Windows Sony USB Device Driver on your Windows computer. http://www.sony.com/support/ For details on installing, refer to the download pages.
The headphone amplifier needs to be connected to your Windows computer at a certain point while installing the driver software. In this case, connect the Windows computer to the Xperia/WALKMAN/PC (USB AUDIO) connecting port of the headphone amplifier using the micro-USB cable (supplied).
Hint
There is no need to install the driver software on a Mac computer.
Note
If the driver software is not installed on your Windows computer, music files cannot be played back via the headphone amplifier.

Charging the battery via a computer
The headphone amplifier contains a rechargeable lithium-ion battery, which should be charged before using it for the first time.
1. Rotate the power/volume knob counterclockwise, until it clicks, to turn off the headphone amplifier. The battery charges only when the headphone amplifier is off. Rotate the power/volume knob clockwise to turn on the headphone amplifier. Rotate it more to adjust the volume.
2. Connect your booted computer to the DC IN 5V port of the headphone amplifier using the micro-USB cable (supplied).
The POWER/CHG indicator lights up in red while the battery is being charged, and the indicator turns off when charging is completed.
Charging is completed in about 15 hours.*1
If the battery is not charged properly, the POWER/CHG indicator will flash in red. *1 Time required for empty battery to recharge.
Help Guide
How to Use

When the battery cannot be charged
Check that the headphone amplifier and your computer are firmly connected via the micro-USB cable (supplied). Use only the supplied micro-USB cable. Do not charge the battery using any other USB cable. Check that the computer is turned on and not in standby, sleep or hibernation mode. If the computer enters standby, sleep, or hibernation mode while the headphone amplifier is connected to the computer, the POWER/CHG indicator turns off and the battery charge will not be completed properly. In this case, change the computer settings and then charge the battery again. Check that the headphone amplifier is directly connected to a computer using the micro-USB cable (supplied). Charging may not be completed properly by an indirect connection, such as via a USB hub.
Battery life*2
Analog connection: Approx. 28 hours*2
Digital (balanced) connection: Approx. 5 hours*2
*2 when using the headphone amplifier at 1 mW + 1 mW output (24 ). Time may vary, depending on the immediate environment or conditions of use.
Hint
The battery can be charged via an AC outlet by using the recommended USB AC adaptor (AC-UD20) (sold separately). Charging is completed in about 6 hours.
Note
The charge will continue for about 10 hours, then the timer function of the charge protection circuit will stop the charging. If you want to continue charging, disconnect and reconnect the micro-USB cable. When the headphone amplifier had not been used for a long time, it may take a while for the POWER/CHG indicator to light up in red. In this case, do not disconnect the micro-USB cable from the headphone amplifier. Wait until the POWER/CHG indicator lights up in red. Charge the battery in an ambient temperature between 5 C to 35 C. If you try to charge the battery outside this range, the POWER/CHG indicator may flash in red, but the battery may not be charged. When the battery is full, the POWER/CHG indicator may not light up in red. When storing the headphone amplifier for a long time, avoid a place subject to high temperatures.

Charging the battery via an AC outlet
The battery can be charged via an AC outlet by using the recommended USB AC adaptor (AC-UD20) (sold separately). For details on the adaptor, refer to its operation manual.
1. Rotate the power/volume knob counterclockwise until it clicks to turn off the headphone amplifier. The battery charges only when the headphone amplifier is off. Rotate the power/volume knob clockwise to turn on the headphone amplifier. Rotate it more to adjust the volume.
2. Connect the DC IN 5V port of the headphone amplifier and the USB AC adaptor (AC-UD20) (sold separately) using the micro-USB cable (supplied), then connect the USB AC adaptor to an AC outlet.
The POWER/CHG indicator lights up in red while the battery is being charged, and the indicator turns off when charging is completed.
Charging is completed in about 6 hours.* If the battery is not charged properly, the POWER/CHG indicator will flash in red. * Time required for empty battery to recharge.

Note
The charge will continue for about 10 hours, then the timer function of the charge protection circuit will stop the charging. If you want to continue charging, disconnect and reconnect the micro-USB cable. When the headphone amplifier had not been used for a long time, it may take a while for the POWER/CHG indicator to light up in red. In this case, do not disconnect the micro-USB cable from the headphone amplifier. Wait until the POWER/CHG indicator lights up in red.
