Why Panasonic?

HD Voice Quality

The audio transmission technologies that have been accumulated by Panasonic over the years enable clear sound for smooth, comfortable conversations.

Wide band codec

Wide band voice, which supports the G.722 audio codecs, enables you to hear each other’s voice clearly for smooth communication.

Receiving Frequency Response

In contrast to narrow band (except for G.722), which covers only part of the human voice range, wide band (G.722) covers a wider range.

Advanced speaker design

Low-frequency bandwidth output is increased by the use of two types of cone paper to make it easy to hear even low-pitched voices with excellent clarity.

Unique speaker cone

The use of a powerful magnet also raises the sound pressure across the entire bandwidth. This makes comparatively soft voices, which were previously difficult to hear, clear and easy to understand.

Stronger magnet

Larger aperture rate for the KX-UDT121/111 receiver makes high-frequency voices easier to hear.

Frequency characteristic for aperture rate
Stable conversation quality

Moving around while talking on an ordinary cordless phone causes voice data errors, and interruptions, due to the cyclic valleys of the signal and interference from sound reflections. Previous models verify each frame of the received voice data. When a bit error occurs in the frame, that frame is muted, so the sound is interrupted in units of about 10 ms. Panasonic DECT communication technology in the KX-UDT121/111 shortens the error detection cycle, so that even if an error should occur, muting is reduced. This prevents unnatural voice interruptions for more comfortable conversations.

Large-capacity speaker box

The large-capacity speaker box improves low-frequency reproduction (approximately 300 Hz). It also prevents the sounds generated by the speakers from leaking inside the cabinet, and outputs them to the front of the speaker unit to achieve a higher sound pressure level. By preventing the speaker output inside the cabinet from entering the microphone, echoes are greatly reduced.

Noise measures

- Noise Reduction Function

Ordinarily, when talking in a noisy environment, the background noise is transmitted to a receiver through a mouthpiece and the receiver can't hear the voice easily. The KX-UDT121/111 detects the background noise and passes the voice sound through a filter to remove the noise, then sends the sound to the other party. The sound that reaches the other party contains clear voice sound in which the noise reduced.

Detects and removes the background noise.

- Dynamic Listening Volume Control Function

When moving from a quiet place to a noisy place, the receiver volume must be raised or the sound will be lost in the noise. When the KX-UDT121/111 detects noise, it automatically increases the receiver volume to an easy-to-hear level.
