User manual XTANT PQM1

[. . . ] During the "tuning process", the PQM-1 may be installed "vertically" using the right angle header connector. However, the final mounting position must be in a "horizontal" position (using the header connector on the bottom of the circuit board) to allow the cover to be re-attached. [. . . ] A clockwise rotation increases frequency while a counterclockwise rotation decreases frequency. FREQUENCY MODULE: The supplied frequency modules divide the audible frequency range into three bands. The range of the modules are: 20 Hz to 200 Hz, 200 Hz to 2 kHz, and 2 kHz to 20 kHz. Simply install one of the modules and its frequencies are selectable via the FREQUENCY CONTROL. "Q" ADJUSTMENT:"Q" is the property of an equalizer that determines the range of frequencies affected on either side of the center frequency. "Q" is equal to the center frequency divided by the bandwidth. The PQM-1's "Q" adjustment ranges from a narrow bandwidth of 10 to a very broad bandwidth of 1. A clockwise rotation increases "Q" while a counterclockwise rotation decreases "Q". BOOST/CUT: This control is used to boost or cut the level of the center frequency. Its adjustment ranges from 18 dB of cut at full counterclockwise rotation to 18 dB of boost at full clockwise rotation. Flat response (0 dB ­ no cut or boost) occurs at mid rotation when the slot on the control is in the horizontal position. FOUR - YEAR LIMITED U. S. A. WARRANTY This warranty gives you specific legal rights, and you may also have other rights which vary from state to state. [. . . ] Some states or provinces do not allow the exclusion or limitation of incidental or consequential damages or limitations on how long an implied warranty lasts; so the above limitations or exclusions may not apply to you.
