Care And Maintenance - Peavey TriFlex Manual

Excessive High Frequency Output from the Subwoofer
Ensure the Mono button (5d) is switched to the ON (In) position. This should eliminate any high frequency output
from the subwoofer. If the unit is being used in three-channel stereo mode‚ some high frequencies may be
generated by the subwoofer when a high-frequency signal is present in only one channel. This is normal and should
not present a problem.
Male Vocals Sound Muddy or Boomy
The level of the subwoofer may be turned up too high or the KOSMOS may be set too high. Turn down the
®
subwoofer level by turning down the Quake Sub level control (7a) until the sound improves. To reduce the
™
amount of KOSMOS processing without changing the subwoofer level‚ turn the Master System level control (6)
down and the Quake Sub level control (7a) up until the subwoofer is back at the previous level. When in three-
channel operation‚ turn the Quake Sub level control (7a) down.
Distorted or Fuzzy Sound
First‚ ensure the mixer (signal source) is not clipping or being overdriven. Make sure the volume control (6) on the
TriFlex has not been set too low. Remember‚ it takes a lot of signal to drive the unit to full power.
™
Check that the input plugs are fully seated in the input jacks (5) on the rear panel of the TriFlex. Ensure that the
proper inputs are being used for the line-level signals and that a power amp has NOT been plugged into one of the
input jacks of the TriFlex. If an extension cord is being used to supply AC power to the unit‚ ensure that it is of
sufficient current capacity and that it is not also being used to supply power to any other device.
The TriFlex has built-in EQ to extend and smooth the natural response of the woofer in any system. Bass boost is
applied and the system has a nominally flat response and should require little‚ if any‚ additional EQ. If excessive bass
boost has been added externally to the TriFlex‚ it could cause premature overload at very high SPLs. Reducing the
amount of external (mixer or rack) EQ should eliminate any distortion. If the KOSMOS function switch (7c) has
been engaged‚ try bypassing it to see if that eliminates the distortion.
If you are using additional speakers connected to the Left and Right outputs (9)‚ ensure they 8 Ohm minimum
impedance. Remove the speakers temporarily to determine if this is the source of distortion. If the distortion is
emanating from the left and right speakers‚ the total capacity of the TriFlex or the speakers has possibly been
exceeded. Reduce the drive level and re-check the speakers for impedance (8 Ohm minimum).
CARE & MAINTENANCE
Your TriFlex is a sturdy and durable product that will provide years of reliable use if properly cared for. Use
common sense and read the safety warnings to avoid hazardous operating conditions. The unit must be
disconnected from the AC power source before any maintenance is performed. Please refer all service issues to
qualified service personnel.
Sunlight/Heat
Avoid prolonged exposure to direct sunlight, as this may cause the unit to overheat and shut down. Excessively hot
operating conditions can also cause a thermal shutdown. Do not store in extremely hot or cold conditions or
extremely high humidity.
Cleaning
A dry cloth may be used to remove soil or other dirt. Never use strong solvents on the TriFlex. Do not allow any
fluids to drip inside the TriFlex system's vent openings, or through the grille.
Check for Secure Hardware
After the first few months of use and periodically thereafter‚ check the hardware for tightness. Make sure to check
the rear-panel screws and the baffle screws. The unit‚ in use‚ is subject to a great deal of vibration that may cause
the screws to loosen over time.
