Inputs (5)
The line-level left (5a) and right (5b) stereo channel input jack groups consist of a combo female XLR and 1/4" TRS
connector and a male XLR running in parallel. This arrangement allows the audio input signal to be daisy-chained to
additional TriFlex units, or other line-level devices, such as power amps for remote speakers.
Unbalanced‚ L/R stereo RCA-type input jacks (5c) are also provided for CD players or similar units. A mono switch
(5d) feeds the left input to both channels when not running in stereo mode.The adjacent yellow LED (5e) lights when
the unit is placed in mono mode.
Master System Level (6)
When used in conjunction with the KOSMOS
TriFlex. The adjacent red LED (11) indicates activation of the built-in DDT
maximum power output. See number (11) below for more details on DDT compression.
KOSMOS (7)
The KOSMOS feature is a low-frequency reinforcement and stereo imaging enhancement system that augments the
input signal by generating bass notes one octave below (Quake
to be widened (Xpanse
The Quake Sub Level knob (7a) sets the powered subwoofer output and simultaneously sets the amount of
KOSMOS Quake function. The Xpanse knob (7b) controls the amount of high frequency expansion applied to the
high-pass outputs (8) and the speaker level outputs (9).The bypass switch (7c) bypasses the KOSMOS entirely. When
in bypass mode‚ the Quake Sub Level knob sets the powered subwoofer level without any KOSMOS effect. The
adjacent‚ blue LED (7d) illuminates when the Quake function is active.
High-Pass Output (8)
These left and right‚ line-level‚ high-pass frequency outputs track with the level of the Master System Level control
(6). They provide a 120 Hz high-pass output for a separate or remotely located powered speaker system, or a
power amp used with a passive speaker system.
Speaker Level Powered Outputs (9)
The left and right speaker level outputs allow connection of the TriFlex stereo, satellite mid/high frequency speakers.
The signals at these outputs are passively high-pass filtered to protect the satellite speakers from excessive low bass.

Ground Lift Switches (10)

These switches can break ground loops on the input channels (10a) and high-pass outputs (10b). Leave these in the
normal position unless there is a need to break such a ground loop (i.e., unusual system hum or noise). They can be
switched independently or in combination to reduce any system hum.
DDT LED (11)
This LED will illuminate at the onset of power amplifier clipping. If the LED is flashing quickly and intermittently‚ the
unit is just reaching the clipping threshold. A steady glow means the unit is reducing signal gain to limit the output to
all of the speakers. During initial power-up‚ the DDT LED will light‚ indicating that the RampUp™ gain-reduction
circuitry is activated.
