Hifionics HFI2000D, HFI100.4 manual Amplifier Feature Descriptions, HFi100.2 2-CHANNEL Amplifiers

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.

!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.

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.

	L					PROTECT
	6V 0.2V	0dB 12dB	FULL LPF HPF	60Hz 12KHz	30Hz 250Hz	MONO STEREO

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.
