D. Try to route cables so that people will not trip over them, or tip the speaker over. Use of duct
tape, cable channels or guards, or other appropriate tie-down/cover–up devices should be carefully
considered and implemented.
E. When installing or de-installing the speaker on the stand, it is a good practice to have a helper if
possible, as it can be hard to "thread the needle" and mate the stand cup to the stand pole while
holding the TriFlex
speaker stand and pole down while the TriFlex II Satellite is removed from the stand pole — this prevents
the TriFlex II Satellite from pulling the pole up with it.
F. When using stands outdoors, never attach banners or flags to the stands or the TriFlex II Satellite
speaker system. Strong winds may cause the speaker to blow over. If there is a possibility of windy
conditions, then it may be prudent to consider weighting or locking down the stand legs to prevent the
TriFlex II Satellite speaker system from being blown over.
COnnECTInG A SIGnAL TO THE TRIFLEX II
There are a variety of ways to input a signal to the TriFlex II.
The two inputs (7,10) provide a balanced line-level input, allowing the use of a 1/4" TRS (ring-tip-sleeve) type
phone plug OR a male XLR plug.
Unbalanced inputs are also provided, as the 1/4" input (7,10) can take a standard single-ended (tip-sleeve)
phone plug or the RCA phono jacks (14) can be used. The RCA jacks are providing a Left and Right stereo input,
as the TriFlex II is a 2 channel sound system.
Do not connect cables to the jacks while the unit is On and the Master System Level knob is turned up! While
a standard single-ended 1/4" phone plug-equipped cable will work well and the balanced input circuitry of
the inputs (7,10) will provide some interference rejection, a balanced cable using either the balanced TRS 1/4"
phone plug or the XLR plug will provide superior interference rejection and performance.
Sometimes, with difficult interference problems, it will 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, always turning
the Master System Level (5) control down before plugging and unplugging cables or engaging the ground lift
switch.
Use of high quality, premium cables is recommended for the TriFlex II, as these usually have better shielding
and materials and will provide greater long-term reliability. The best option is a shielded balanced XLR cable
no longer than necessary to reach the TriFlex II. It is usually a good idea to leave some slack at the input to the
TriFlex II, and also to tape the cables down or run them under a cable guard to avoid anyone tripping over them
or pulling the cable out of the TriFlex II system input.
MASTER SYSTEM LEVEL COnTROL ADJUSTMEnT
The TriFlex II is equipped with a Master System Level (5) control on the input to facilitate use in many different
applications. With the Master System Level control adjusted fully clockwise, gain is at maximum and the input
sensitivity is 0.200V RMS for full-rated output. When driving the TriFlex II from a mixer, it may be advantageous
to reduce the input sensitivity by turning the Gain control to the halfway point. The TriFlex II will now more
closely match a typical power amp.
If the mixing board indicates clipping of its output signals, then all of the TriFlex II power capability is not being
utilized cleanly. Clipping the signal before it gets to the TriFlex II is not optimal. Reduce the mixer output level
and turn up the Level control on the TriFlex II.
The amplifiers in the TriFlex II are equipped with DDT
If the sound seems heavily compressed, check this indicator; if it is blinking RED more than occasionally, then
the drive level from the mixer (or the Level control/s {5,6} on the TriFlex II) needs to be reduced.
When first turning on the sound system, switch on all upstream electronics first, then the TriFlex II with its
Master System Level control fully counterclockwise (all the way down). Begin checking levels with the mixer
output level controls all the way down, and bring them up slowly with the TriFlex II Master System Level control
set to the desired setting (one-half way up recommended to start).
It is not good practice to turn the Master System Level control on the TriFlex II all the way up and then try to
control level only from the mixer, as this approach would tend to pick up excess noise. Best practice would be
to run a "hot" signal from the mixer down the cable to the TriFlex II, and then turn the TriFlex II Master System
Level control up only as much as necessary to reach full desired output. With this approach, it is necessary to
verify the mixer output is not clipping.
