Volume Control Adjustment - Peavey TriFlex Manual

OPERATING INSTRUCTIONS
CAUTIONS
Clearance of 12" or 10 cm from the rear of the sub to any combustible surface must be maintained.
The left input jack group or right input jack group (5) are hard-wired together to allow use of any
of the connector types as an input and to allow a further send or daisy-chaining of the input signal
to some other audio device (such as another TrifFex
the TriFlex left input jack group or right input group could damage the output(s) of the source
unit(s). Use a mixer to combine two or more signals into a single channel before sending to the
TriFlex input.
Warning: The TriFlex sound system can permanently damage hearing. Use caution when setting the
overall maximum loudness.This system is capable of SPL in excess of 128 dB at 1m from the speaker!
Using the Pole Stand Base
The included tripod pole stand allows the use of the TriFlex satellite speakers. These pole stands should not be
extended beyond 65" in height or carry more than 20 lbs. each in weight.
Sending Audio Signal to the TriFlex
There are a variety of ways to provide audio signals to the TriFlex. The balanced line-level input(s) allow the
use of an XLR plug or a 1/4" phone plug: either a standard, single-ended TS (tip/sleeve) plug or a balanced TRS
(tip/ring/sleeve) type 1/4" phone plug. It is not advisable to connect cables to the jacks while the unit is ON and
the volume is turned up.
The XLR plug will provide superior performance, whereas the standard‚ single-ended 1/4" phone plug will also
work and the balanced input circuitry will provide some interference rejection. Plugging into the RCA jacks or
plugging a mono 1/4" plug into the combo jack will cause the thru jack to operate in unbalanced mode. If hum
or other interference problems result from the thru output‚ it will be helpful to lift the ground TriFlex input
only. This can be accomplished via the convenient ground lift switch (10a) found underneath the input jack
group. Check any input changes carefully. Always turn the volume controls down before plugging and
unplugging cables or switching the ground lift switches.

Volume Control Adjustment

The TriFlex is equipped with a Master System Level volume control (6). When the Master System Level is
adjusted fully clockwise‚ gain is at maximum and the input sensitivity is 0.375 VRMS for full-rated output. When
this control is set halfway up‚ gain is unity and 1.5 VRMS will drive the system to full power output. When
driving the TriFlex from a mixer‚ it may be advantageous to reduce the input sensitivity by turning the volume
control to the halfway point. At this setting‚ the TriFlex will more closely match the output of a mixer and
provide an appropriate input of the internal power amp.
The amplifiers in the TriFlex are equipped with DDT
illuminates when DDT is activated. This LED is located next to the Master System level. The DDT circuit will
automatically reduce the system gain to a level just slightly into clipping, guarding the speakers against the
overloads. Situations that may activate the DDT circuit include uncontrolled feedback, oscillations, or an
improper equipment setting or malfunction upstream from the TriFlex system.
Always turn any peripheral units to ON before turning on the TriFlex. Also‚ make sure the Master SystemLevel
is completely down (counterclockwise) before turning the unit on. Likewise, turn the TriFlex system to OFF
before shutting down any peripheral units.
