Terminology and technical explanations
Following are explanations of terminology used in this guide.
USB DAC
The USB DAC converts digital audio signals, sent via a USB cable connected to a computer, into an analog
audio signal, which allows it to be played. This makes it possible for computer applications to play high-
quality audio.
YPAO (Yamaha Parametric room Acoustic Optimizer)
This is a proprietary Yamaha technology that automatically optimizes for room acoustics. A special YPAO
microphone is used to detect speaker connections and measure the distance from them to the listening
position. It measures the acoustic characteristics of the space and automatically adjusts parameters such as
volume balance and frequency characteristics.
Bi-wiring Connections
When connecting an amplifier to speakers, this connection method uses separate wires for the low-
frequency speaker unit (woofer) and the mid-high frequency speaker unit (tweeter). This method of
connection is possible if the speakers are bi-wiring compatible (if they have terminals for both low-
frequencies and mid/high frequencies).
Loudness
This function makes it easier to hear bass and treble even at low volumes. It allows the listener to enjoy
natural sound even at low volumes by compensating for the human auditory characteristic that makes it
difficult to hear bass and treble at low volumes.
