Equalization adjustments
Figure 3 shows the SEQ-2’s ten trimpots and their respective center frequencies. Figure 4 shows the adjustment range for each
trimpot. Note that the rate of change in boost or cut varies over the trimpot’s rotation; the adjustment is finer toward the middle
and more dramatic at the extremes.
Closing up the amplifier
•
EX, MXa, or legacy CX models only:
Carefully reposition the input board/SEQ-2 assembly into the amplifier chassis and
secure it by fastening the two mounting screws. Make sure the screws are tightened snugly, but do not over-torque them.
Re-install the upper blank panel.
•
PowerLight, PLX, DCA, or current CX models only:
re-install the chassis cover and secure it by fastening all the screws.
Make sure they are tightened snugly, but do not over-torque them.
Installation of the SEQ-2 is now complete, and the amplifier is now ready to be re-installed into the system.
CAUTION:
Sometimes it may be necessary to adjust the SEQ-2 while the amplifier is running.
Because of the risk of exposure to high voltages inside the amplifier, such adjustments must be
made
only
by a qualified technician.
CAUTION:
Use only non-conductive tools to adjust an SEQ-2 that is installed in an amplifier.

Disclaimer
QSC Audio Products, Inc. is not liable for any damage to speakers, amplifiers, or any other equipment that is caused by
negligence or improper installation and/or use of the SEQ-2.
Product Warranty
QSC Audio Products, Inc. guarantees the SEQ-2 to be free from defective material and/or workmanship for a period of three
years from date of sale, and will replace defective parts and repair malfunctioning products under this warranty when the
defect occurs under normal installation and use—provided the unit is returned to our factory via prepaid transportation with
proof of purchase (sales receipt). This warranty provides that examination of the returned product must disclose, in our
judgment, a manufacturing defect. This warranty does not extend to any product which has been subject to misuse, neglect,
accident, improper installation, or where the date code has been removed or defaced.
Setting up the SEQ-2
The SEQ-2’s equalization settings may be adjusted only while the amplifier chassis is open (on BusCard-equipped models) or
while the input card is removed (on models using Open Input Architecture), because the trimpots are inaccessible once the
amplifier chassis is closed.
