Panasonic SC‑HTB70 | Sound Bar ‑ 2.1 | Channel ‑ Wireless Kirsi Kuutti

What features does it have? Play sound wirelessly or via aux from tv, gaming consoles, computers and smart devices. Bluetooth (2.4 GHz) Has modes such as… “Standard” (factory preset), “Stadium” (highly realistic live broadcast sound) , “Music” (expansive sound), “Cinema” (3 dimensional sound), “News” (enhance voices), “Stereo” (surround effects turned off).

How are features implemented in circuitry? Mode settings change which filter or amplifier circuits the sampled sound gets passed through “Music” (expansive sound) - frequency and amplitude range increases to insure all the instrumental sounds/ imperfections are noticeable “Cinema” (3 dimensional sound) - simply assigns sounds from the input to play from various speakers around the room. If noise in the movie is being made like it is coming from behind the main character, that sound is characterized so the speaker behind the user plays that noise. “News” (enhance voices) - sound sampled from the newscast goes through a filter that amplifies the frequency range a human voice would have (85Hz- 255Hz) with a voice band. Bass is filtered out, treble is amplified.
