PQM-1 OPERATION
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. Xtant Technologies (Xtant) warrants its amplifiers and accessories to be free from defects
in materials and workmanship under normal use and service for a period of four (4) years from the
date of original purchase when the unit is installed by an Authorized Xtant Select Dealer. Non-
Authorized Dealer installed products carry a one (1) year parts and labor limited warranty. The extent
and conditions of Xtant’s Limited Warranty are as follows:
1. Authorized Xtant Select Dealer Installed Products: Xtant will either repair or replace at no charge,
to the original purchaser, any unit which Xtant’s examination discloses to be defective and under war-
ranty, provided the defect occurs within four (4) years from the date of purchase when the unit is
installed by an Authorized Xtant Select Dealer and the product is returned immediately to Xtant. This
warranty is not transferable.
2. Non-Authorized Xtant Dealer Installed Products: Xtant will either repair or replace at no charge, to
the original purchaser, any unit which Xtant’s examination discloses to be defective and under war-
ranty, provided the defect occurs within one (1) year from the date of purchase and the product is
returned immediately to Xtant. This warranty is not transferable.
3. The date of purchase and proof of Authorized Dealer Installation of an Xtant amplifier and/or
accessory must be established by an original (or copy of the original) sales receipt which must accom-
pany the article being returned for warranty work.
4. This warranty shall NOT apply to any Xtant unit found to have the original factory serial number
removed or defaced. All products received (by Xtant) for in warranty or out of warranty repair, with
their original serial numbers removed or defaced, will NOT be repaired and will be returned to
sender, freight collect.
5. The provisions of this warranty shall not apply to any Xtant unit used for a purpose for which it is
not designed, which has been repaired or altered in any way, or which has been connected, installed,
or adjusted other than in accordance with the instructions furnished in Xtant’s owner’s manual. Nor
shall this warranty apply to any part which has been subject to misuse, neglect, or accident.
6. Xtant does not authorize any other persons to assume any other liability in connection with its prod-
ucts. This warranty is the only express warranty made by Xtant applicable to its products. Any
implied warranty or merchantability or fitness for a particular purpose applicable to Xtant’s ampli-
fiers and or accessories is limited in duration to the duration of this limited warranty. Xtant shall not
be liable for the incidental, consequential, or commercial damages resulting from the breach of this
written warranty. 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.
7. Your unit will be serviced on an in-warranty basis within the warranty period for the correction of
warranted defects. If improper operation of your Xtant product should occur, contact your Authorized
Xtant Select Dealer for assistance with the return and factory repair of your Xtant product. If an
Authorized Xtant Select Dealer is not available, please contact Xtant’s Customer Relations
Department at (602) 970 9900 from 8:00 am to 5:00 pm (MST) for assistance.
The PQM-1 is a one band, parametric equalizer. Adjustments are made using
the three, circuit board mounted, potentiometers. These controls are simple to
operate and provide a wide range of adjustment.
FREQUENCY CONTROL
is used to select
the center frequency for equalization. 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 fre-
quencies affected on either side of the center
frequency. “Q” is equal to the center frequency
divided by the bandwidth. As “Q” goes up, bandwidth decreases. 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 counterclock-
wise 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.
