Explanation of terms
Bluetooth
Technology for near field wireless communications. This unit can connect
to Bluetooth devices wirelessly. To establish a Bluetooth connection, you
must perform pairing (registering) beforehand.
DSD (Direct-Stream Digital)
One of the audio data recording methods, it is the signal aspect used to
store audio signals on a super audio CD, and is Δ-Σ modulated digital
audio. It is configured of an array of single bit values at a 2.8224MHz
sampling rate.
NFC (Near Field Communication)
Technology for near field wireless communications. You can just touch
this unit with a device with the NFC function to establish a connection
between this unit and the device.
Sampling frequency
Sampling involves taking a reading of a sound wave (analog signal) at
regular intervals and expressing the height of the wave at each reading in
digitized format (producing a digital signal).
The number of readings taken in one second is called the “sampling
frequency”. The larger the value, the closer the reproduced sound is to the
original.
Pairing
Pairing (registration) is an operation that is required in order to connect a
Bluetooth device to this unit using Bluetooth. When paired, the devices
authenticate each other and can connect without mistaken connections
occurring.
When using Bluetooth connection for the first time, you need to pair this
unit and the Bluetooth device to be connected.
This unit can store pairing information for a maximum of 8 devices.
Protection circuit
This is a function to prevent damage to devices within the power supply
when an abnormality such as an overload, excess voltage occurs or over
temperature for any reason.
Linear PCM
Uncompressed PCM (Pulse Code Modulation) signals. Unlike lossy
compression audio sources such as MP3, no audio quality or dynamic
range deteriorates.
