AMPLIFIER FEATURE DESCRIPTIONS

TITAN TXi SERIES AMPLIFIERS:

! Each model is capable of 4 & 2-Ohms stereo per channel, or 4-Ohms mono bridged operation ! All Hifonics amplifiers feature a comprehensive diagnostic system, with speaker lead short circuit,

and amplifier DC faults indicated by the red “PROTECT” LED.

except the mono amps which are capable of 4, 2 and 1-Ohm loads.

CAUTION: DO NOT OPERATE ANY AMPLIFIER BELOW THE INTENDED IMPEDANCE.. YOU

Tri-Mode operation with any stereo pair of amplifier channels is possible, as with all bridgeable

WILL CAUSE DAMAGE TO THE AMPLIFIER THAT WILL NOT BE COVERED UNDER THE

amplifiers.

! The input sensitivities for rated output powers are listed below for each model.

WARRANTY PRINTED IN THE BACK OF THE MANUAL. 2 & 4 Channel amps are capable of 4

! All crossovers are fully variable in their respective ranges.

and 2-Ohms wired stereo and 4-Ohms wired mono bridged. The mono amps are capable of 4, 2

! Crossover filters are 12dB/Octave.

and 1-Ohm.

! A POWER LED indicates the powered up and turned on condition.

The X-OVER slide switch selects the internal crossover functions:

-The input signal is routed directly to the LINE OUT RCA jacks, regardless of the X-OVER setting

simplifying daisy chaining of amplifiers.

-HPF: Selects the built in HIGH PASS filter, variable from 60 Hz to 1.2kHz.

-FULL: Bypasses all crossovers for full frequency range operation.

-LPF: Selects the built in LOW PASS , variable from 30 Hz to 250Hz.

MODE: The mode switch allows you to choose Stereo for full range 2 channel operation or MONO

for bridging operation

HIGH INPUT: If your radio/CD player does not have unbalanced (RCA) outputs, you can use the

HIGH level (wire) inputs.

LINE INPUT: The line input accepts unbalanced (RCA) inputs from 0.2V to 5V.

LINE OUTPUT: The line output passes through signal from the line inputs which allows you to daisy

chain multiple amplifiers from one signal.

Note that the LOW PASS signal is MONO.

-In the LPF position, the HIGH PASS filter acts as a subsonic

filter.

-When the LPF mode is selected, a 0 to +12dB, at 45Hz, BASS

-EQ is also switched in.

The 4 channel amps have the same features as the 2 channel models accept that there are 2 sets of

controls.

1 set for channels 1 & 2 and 1 set for channels 3 & 4.

In addition, the 4 channel models have a Mode switch which allows you to select 2, 3 or 4 channel

operation.

-The LINE INPUT signal is routed directly to the LINE OUT RCA jacks, regardless of the X-OVER

setting simplifying daisy chaining of amplifiers.

-SUBSONIC: Allows you to adjust the crossover filter from 15Hz to 35Hz.

-LPF: Allows yo to adjust the LOW PASS crossover filter from 35Hz to 250Hz.

LEVEL: Adjusts the input sensitivity from 0.2 volts to 9 volts.

BASS EQ: The Bass EQ is adjustable from 0dB to 10dB.

REMOTE: This is the input jack for the under-dash bass remote module.

LINE INPUT: The line input accepts unbalanced (RCA) inputs from 0.2V to 9V.

LINE OUTPUT: The line output passes through signal from the line inputs which allows you to daisy

chain multiple amplifiers from one signal.

The mono amps are capable of 4, 2 & 1-Ohm loads.

Operating the amp below 1-Ohm can cause damage to the

amp not covered in the warranty.

LINE INPUT: Accepts unbalanced RCA inputs from 0.2 volts to 6 volts.

LEVEL: The input level control allows you to match the amplifier input sensitivity to the output level of

the RADIO/CD source from 0.2 volts to 6 volts.

REMOTE: The RJ45 Remote jack accepts the Bass Remote Module.

BASS EQ: The Bass Boost is fully adjustable from 0 to 12dB at 45Hz.

SUBSONIC: The variable Subsonic filter is fully adjustable from 15Hz to 55Hz.

LPF: The built-in low pass frequencies are fully variable from 40 to 150Hz.

POWER: Indicates that the amp has power, ground and remote turn-on input via a green L.E.D.

PROTECT: Indicates that the amplifier has detected a fault and will not operate. There are several

possible problems that can cause the amplifier to go into the protect mode. See the trouble

shooting guide in the back of the manual for details.

The mono amps are capable of 4, 2 & 1-Ohm loads.

Operating the amp below 1-Ohm can cause damage to the

amp not covered in the warranty.
