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 1’s and 0’s, 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
Note
There is no need to install the driver software on a Mac computer.

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.

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. When storing the
headphone amplifier for more than a year, charge the battery every six months to prevent over discharge.
