Sound field Specialization is a method to increase the field of sound for a broader and more encompassing audio experience. Specifically for (R1280DBs) copies of the left and right channels are subtracted from each other. This creates a signal that removes any audio or instrumentation that is shared by both channels. Next, a bandpass filter sets the frequency range for which the effect is active. After which, a level control adjusts the strength of this channel before being reintroduced back into the original left and right channels. We highly recommend using this effect for movie or TV watching instead of normal music streaming. You can adjust the bass and treble EQ knobs to affect the sound slightly based on your preferences.
