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.
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.
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.
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.
