Based on the phenomenal MASH noise shaping technology used for many years in Panasonic products, the Anti-Jitter Digital Amplifier in the SC-HTB350 markedly reduces jitter and distortion that can affect audio clarity, producing pure brilliant sound. The result is high quality sound with a full surround effect that rivals that of a real home theater. This speaker can be split into two by removing the connecting hardware in the center. Then you have four great installation options to suit your room. Try a horizontal or vertical speaker layout and have them free standing or wall mounted. The audio signal of the SC-HTB350 is wirelessly transmitted from the main unit to the subwoofer, eliminating troublesome wiring and restrictions on where the subwoofer can be placed for complete layout freedom. Music archived on your smartphone or PC can be played back via Bluetooth. Enjoy crystal clear sound with no worry about music signal interference from obstructions. By expanding the sound field in the upper front area of the TV screen, Clear-mode Dialog gives the sound greater depth. It also makes voices sound like they’re coming from the center of the screen. Dialog volume is adjustable to 4 levels. This function is great for when dialog is drowned out by the surround sound and is difficult to hear.
