Although it will have the feel of adjustment like the other controls on this panel (there are no detents), the Gain control has 33 discrete steps in adjustment.
ESP FEATURES AND CONTROLS The ability to access the feature settings of your amplifier is only possible with the use of a Directed Electronics Bitwriter unit. Firmware version 1.8 or ® later is required in the Bitwriter ® Versions prior to 1.8 will not program the amplifier.
N N o o t t e e : : Remember that the 1200t uses a digital gain control with a finite number of adjustment steps. A very small adjustment may not cause any audible change in level.
SUBSONIC FILTER ADJUSTMENT This amplifier incorporates a subsonic filter to maximize the performance of a subwoofer. The subsonic filter is a high pass filter that removes unwanted bass output at very low frequencies from the woofer. This increases the output of a subwoofer by as much as 3 dB by increasing the mechan- ical power handling of the subwoofer.
