Hifionics ZXI150.4, ZXI40.4, ZXI80.4 Amplifier Feature Descriptions, ZXi200.2 2-CHANNEL Amplifiers

AMPLIFIER FEATURE DESCRIPTIONS

ZEUS ZXi AMPLIFIERS:

!Each model is capable of 4 & 2-Ohms stereo per channel, or 4-Ohms mono bridged operation except the 5 channel which is capable of 1-Ohm on channel 5.

!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 5 channel amp is capable of 4, 2 and 1-Ohm operation on the 5th channel ONLY.

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.

-HP: Selects the built in HIGH PASS filter, variable from 10Hz to 15kHz.

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

-LP/BP: Selects the built in LOW PASS , variable from 30Hz to 150Hz.

BASS EQ: Fixed 45Hz bass boost variable from 0dB to 10dB.

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. 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 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.

-HP: Selects the built in HIGH PASS filter, variable from 10 Hz to 15kHz.

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

-LP/BP: Selects the built in LOW PASS , variable from 30 Hz to 150Hz.

BASS EQ: Fixed 45Hz bass boost variable from 0dB to 10dB.

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 ZXi60.4+1K has three sets of inputs:

Line inputs on RCA jacks for channel pairs 1&2, 3&4, and MONO channel 5. These inputs can be used in various combinations, to suit the application, depending on the settings of the INPUT MODE switch, and the X-OVER switches for channels 1&2, and channels 3&4, respectively.

ZXi200.2 2-CHANNEL AMPLIFIERS

L					L
REMOTE 10Hz 15KHzHP	FULL LP/BP 30Hz 150Hz		0dB 10dB	6V 0.2V	PROTECT
R					R

Note that the LOW PASS signal is MONO.

-In the LP/BP position, the HIGH PASS filter acts as a subsonic filter.

-When the LP/BP mode is selected, a 0 to +10dB, at 45Hz, BASS EQ is also switched in.

-When the LP/BP mode is selected, a 0 to +10dB, at 45Hz, BASS EQ is also switched in.

ZXi60.4+1K 5-CHANNEL AMPLIFIERS

INPUT MODE slide switch:

- In the CH2 position, ALL five amplifier inputs are selected from the CH1/CH2 RCA jacks. Channel 5 receives a mono mixed signal.

-In the 4CH position, channel pair 1&2 receive input signal from RCA jacks CH1 and CH2, and channel pair 3&4 receive input signal from RCA jacks CH3 and CH4. A mono mixed signal from these four RCA

jacks are also fed to channel 5.

-When 5CH DISCRETE is selected, each channel receives an input signal from its respective input RCA jack. Channel 5 has two jacks on its LINE INPUT, which are summed together.

CH1/2 X-OVER slide switch:

-HI: Selects the HIGH PASS filter, variable from 10Hz to 15KHz.

-FULL: Sets this pair to full range operation.

CH3/4 X-OVER slide switch:

-HI: Selects the HIGH PASS filter, variable from 10Hz to 15KHz.

-FULL: Sets this pair to full range operation.

-LP/BP: Selects the built in LOW PASS , variable from 30 Hz to 150Hz.

CH 5:

-The channel 5 functions were chosen to be very specific to mono bass operation, and not switchable:

-The LOW PASS filter has a variable range from 30 Hz to 150 Hz.

-The BASS EQ gives a bass boost, 0 to +10 dB, at 45 Hz.
