Care And Maintenance - Peavey TriFlex II Bedienungsanleitung

power amp and speaker). If this produces a signal, make sure that all Level controls being used have been
turned up to a satisfactory level (one-third to halfway).
If the TriFlex II has been subjected to direct sunlight or excessive heat, the built-in thermal protection may have
®
been triggered. If so, turn off the TriFlex II and let it cool for a sufficient amount of time.

If there is still no output, contact your authorized Peavey dealer or the Peavey International Service Center.
HUM OR BUZZ
If the TriFlex II System is producing a hum or buzz, this can be AC outlet related. Try plugging the TriFlex II into
a different AC outlet. Sometimes, if a different circuit (breaker) is used for the mixer and for the TriFlex II, it can
cause hum problems. Unless it is not practical, it is best to use the same wall outlet (breaker) to supply power
to both the mixer and the powered speaker.
Ensure that shielded cables have been used to route the signal to the TriFlex II's inputs. If speaker cables with
1/4" plugs are used as input cables instead of shielded cables, they will be prone to hum or buzz.
Hum may be ground loop related. It may be helpful to lift the shield ground on a balanced cable at the TriFlex II
end only by using the ground lift switch (4). Check any input changes carefully by first turning down the Master
System Level control (5), before plugging and unplugging cables, or lifting the shield ground at the speaker end
by using the Ground Lift switch (4).
Check to make sure light dimmers are not on the same circuit as the TriFlex II System, the mixer or any source
devices. If light dimmers are used, then it may be necessary to turn them full On or full OFF to eliminate or reduce
hum. This is a typical AC wiring/light dimmer interference problem, not a design flaw of the TriFlex II System.
The third wire (ground plug) on the AC plug should nEVER be removed or broken off, as this is a potential safety
hazard.
DISTORTED OR FUZZY SOUnD
First, ensure the mixer (signal source) is not clipping or being overdriven. Make sure the Master System Level
control (5) on the TriFlex II has not been set too low. Check that the input plugs are fully seated in the input
jacks (7), (10) or the RCA jacks (14) on the rear panel of the TriFlex II. Ensure that a power amp has not been
plugged into one of the input jacks of the TriFlex II. If an extension cord is being used to provide the 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 II has built-in EQ to extend and smooth the natural response of the subwoofer speaker in the
system. Bass boost has been applied and the system then has a nominally flat response, so it should require
little, if any, additional EQ. The satellite speaker has CD horn EQ designed into the passive crossover. If
excessive additional bass boost or HF boost have been added externally to the TriFlex II, it could cause
premature overload at high SPL. Reduce the amount of any external (mixer, rack) EQ and see if that clears up
the distortion.
Finally, realize that even though the TriFlex II is a powerful and high output unit, it does ultimately have limits,
and it may need additional powered units to provide enough sound output or coverage. In this case, try turning
the mixer levels down a little to see if that clears things up.
If, after checking all the things listed and anything else you can think of to safely check, and the system still
exhibits problems, carefully note all conditions and check with your Peavey dealer for advice.
BOOMY OR POORLY-DEFInED BASS
The TriFlex II system has had the bass output optimized for the capabilities of the subwoofer cabinet and the
woofer inside it. Bass boost has already been applied to the signal in order to equalize it to a nominally flat
response. If additional bass boost is applied via an external equalizer, or via a mixer's channel EQ controls, or
the Sub Level control (6) has been turned all the way up, the bass could become boomy or distorted and muddy
the vocals or midrange signal information. If this occurs, reduce or remove the external bass boost, or turn the
Sub Level control (6) down. When the Sub Level control (6) is turned to the 2 o'clock position, it is matched in
level to the mids and highs of the satellite speakers.

CARE AnD MAInTEnAnCE

Your TriFlex II is a sturdy and durable product and 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 work is done on it. Refer all servicing to
qualified service personnel.
