MONOPHONIC OPERATION
If mono operation is desired, so that the two channels, and thus, both satellites, play the same signal, see the
Monophonic Hook-up Diagram near the end of the manual.

NO OUTPUT AT ALL
First, make sure the unit has AC power and is turned ON. Make sure the LED (13) on the power amp module is
illuminated, it should be illuminated green.
If not, make certain the ON/OFF switch (3) is in the ON position and check the IEC power cord connection (2) by
ensuring it is fully engaged and seated. Make certain the AC line cord is plugged into a working AC outlet.
Finally, check the fuse (1). (See the Rear Panel: Fuse section, for safety instructions.)
Once assured your unit is getting AC power, check that the TriFlex
II is getting a signal. Temporarily disconnect
™
the cable running to its inputs and connect it to some other device capable of reproducing the signal (i.e., a
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) and (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, insure 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
