Assistance
This section assumes that the product functions properly and that one or more product features or functions have
been engaged, defeated, or not properly adjusted.
Begin troubleshooting by taking a moment to review the “Short Form Instructions” portion of this manual. It may
help to identify a feature that has been overlooked and related to the problem.
Symptom:
None of the frequency related slide controls have any affect.
Probable cause#1: The BYPASS switch is engaged, confirmed by illumination.
Probable cause#2: Loss of power, either the POWER switch is in the OFF position, or the product is not
connected to an AC or DC source. The POWER LED will illuminate when the POWER switch
is in the ON position and AC or DC power is available.
Symptom:
The frequency related slide controls below 80Hz have little or no affect.
Probable cause: The HPF has been engaged as confirmed by the illuminated corresponding LED.
Symptom:
Low output even with reasonable settings (approximately “0”)
Probable cause#1: The CUT ONLY switch is engaged as confirmed by the corresponding LED. With the CUT
ONLY switch engaged the red graphics are used and indicate that the 0 position (unity) has
moved from the middle to the top of the slider. The RANGE switch will magnify this effect if it
is engaged as confirmed by the corresponding LED.
Probable cause#2: Incompatible signal to or from other devices in the system.
Symptom:
Distorted sound and/or the PEAK LED is illuminated.
Probable cause#1: Too much boost because the RANGE switch is doubling the amount of boost.
Probable cause#2: Too much boost is occurring due the position of the sliders (above “0”).
Probable cause#3: Incorrect or overdriven input signal being received from another product. Be sure that this
product is only receiving one input signal per channel, XLR or euroblock, not both.
