Sony's Hybrid Digital Processing
Sound quality is the most important issue in wireless transmission. Conventional
analog systems make use of companders to provide the required dynamic
range. However, while compander systems have improved over time, their
inherent problems with sound quality and transient response performance
have yet to be completely solved.
Sony's newly developed Hybrid Digital Processing, which uses DSP (digital
signal processing) for digital companding, realizes high sound quality.

Transmitter
DSP optimizes the audio signal processing applied between the transmitter
and receiver. It provides superb transient response performance. While analog
companding systems cannot reproduce sounds such as a bell or tee shot with
precision, Sony's Hybrid Digital Processing can reproduce them very accurately.
Dynamic Response
Original Sound Analog System
DSP also can correct characteristics of frequency response in the transmission
process for precise reproduction of original sounds.

Clear Channel Scan & Active Channel Scan
The Clear Channel Scan function searches for a channel that is not being
used by another wireless device or by a TV station. This makes it easy to
find an available channel so the wireless microphone can be used without
interference. The Active Channel Scan function detects Sony's wireless
transmitter from the channel lists within a selected group.
IR Sync
The receiver can transfer the desired frequency to the transmitter via IR
connection, and allows for quick and simple setup.
Wide Frequency Coverage
The system's operating bandwidth (up to 72 MHz*
to cover a wide area and provide more channel options.
