AMPLIFIER FEATURE DESCRIPTIONS

HFi AMPLIFIERS:
Each model is capable of 4 & 2-Ohms stereo per channel, or 4-Ohms mono bridged operation
except the mono amps which are capable of 4, 2 and 1-Ohm loads.
Tri-Mode operation with any stereo pair of amplifier channels is possible, as with all bridgeable
amplifiers.
The input sensitivities for rated output powers are variable from 0.2 volts to 6 volts.
All crossovers are fully variable in their respective ranges.
Crossover filters are 12dB/Octave.
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 12kHz.
-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 6V.
LINE OUTPUT: The line output passes through signal from the line inputs which allows you to daisy
chain multiple amplifiers from one signal.
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. Switch to 2 channel if you only have 1 set of RCA's in CH 1/2 and the unit will automatically
supply signal to channels 3/4. Select 3 channel when you only have RCA's in CH 1/2 but plan to run
channels 3/4 bridged. Select 4 channel if you are providing RCA's to channels 1/2 and 3/4.
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 12kHz.
-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 6V.
LINE OUTPUT: The line output passes through signal from the line inputs which allows you to daisy
chain multiple amplifiers from one signal.
-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 30Hz to 250Hz.
LEVEL: Adjusts the input sensitivity from 0.2 volts to 6 volts.
BASS EQ: The Bass EQ is adjustable from 0db to 10dB.
REMOTE: This is the input jack for the remote Level control.
LINE INPUT: The line input accepts unbalanced (RCA) inputs from 0.2V to 6V.
LINE OUTPUT: The line output passes through signal from the line inputs which allows you to daisy
chain multiple amplifiers from one signal.

All Hifonics amplifiers feature a comprehensive diagnostic system, with speaker lead short circuit,
and amplifier DC faults indicated by the red "PROTECT" LED.
CAUTION: DO NOT OPERATE ANY AMPLIFIER BELOW THE INTENDED IMPEDANCE. YOU
WILL CAUSE DAMAGE TO THE AMPLIFIER THAT WILL NOT BE COVERED UNDER THE
WARRANTY PRINTED IN THE BACK OF THE MANUAL. 2 & 4 Channel amps are capable of 4
and 2-Ohms wired stereo and 4-Ohms wired mono bridged. The mono amps are capable of 4, 2
and 1-Ohm.
