www.TurtleBeach.com Multi-Band Equalizer The multi-band equalizer lets you change the tone of the game sound. The sliders will boost or cut the designated frequencies by +/-12dB. The frequencies for each slider are: Low: 100Hz shelving filter Mid 1: 250Hz band-pass filter Mid 2: 1kHz band-pass filter Mid 3: 4kHz band-pass filter High: 8kHz shelving filter The Low and High shelving filters provide a bass and treble boost. The Mid 1, 2 and 3 band pass filters provide a resonant boost or cut at the specified frequency.  TIP: Double clicking a slider sets it to the center position (zero boost and cut) Sound Field Expander The sound field expander can be used for widening a stereo sound field, boosting center sounds and accentuating sounds from the left and right sides. The signal flow of the expander is shown below. The left and right channels are processed independently and split into four paths.  The "Through" path (T) is the direct unmodified sound. The level of this path is controlled by the TGain slider.  The Low Pass Filter path (L) filters out frequencies above 200Hz. The level of this path is controlled by the LGain slider.  The High Pass Filter path (H) filters out frequencies below 200Hz. The level of this path is controlled by the HGain slider.  The left and right High Pass Filter paths are added or subtracted from each other to form a mono signal that is added to the original high-pass filter signals. The add/subtract amount is set by the MGain slider. Page 26
