8.2.1 Level and time-of-flight correction Controls in Monitors and Subwoofer

SAM monitors contain adjustment of the input sensitivity. This is called the level setting. The input
sensitivity can by adjusted from the nominal maximum (0 dB) down to – 60 dB.
The time-of-flight compensation is needed when the monitors are at different distances from the
listening position. The adjustment range for the time-of-flight is from 0 ms (no additional delay) to
45...200 ms, depending on the product. This range enables complex reproduction system with
monitors at different distances from the listening positions to be calibrated for the same level and
time-of-flight for audio at the listening position.

8.2.2 Room Response Equalizer Controls

Each SAM monitor and subwoofer contains a set of tools to compensate for the acoustical
influences of the room. These tools include high frequency Low shelve filters 1 and 2, High shelve
filters 1 and 2, and parametric notch filters 1 to 16. The number and type of room calibration filters
depends on the SAM product. For example, subwoofers contain parametric notch filters, only.
