AMPLIFIER FEATURE DESCRIPTIONS

ZEUS ZXi SERIES AMPLIFIERS
Each model is capable of 4 & 2 ohms stereo per channel, or 4 ohms mono bridged
operation.
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 volt to 6 volt.
All crossovers are fully variable in their respective ranges.

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.
- HI: Selects the built in HIGH PASS filter, variable from 10 Hz to 150Hz.
- FLAT: Bypasses all crossovers for full frequency range operation.
LP/BP: Selects the built in LOW PASS filter, variable from 30 Hz to 150 Hz.
The AMPLIFIER CH 1/2CH X-OVER slide switch selects the input signal for channel
pair 1 & 2:
- HI: Selects the built in HIGH PASS filter, variable from 10 Hz to 150Hz.
- FULL: Bypasses all crossovers for full frequency range operation.
- LP/BP: Selects the built in LOW PASS filter, variable from 30 Hz to 150Hz.
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 +10 dB, at 45 Hz, BASS EQ is also switched
in.
The ZXi8006 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.

Crossover filter slopes are 12 dB/octave for stereo filters, and 24 dB/octave for mono
filters.
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 DIAGNOSTIC, or PROTECT LED.

regardless of the setting of the X-OVER switches.
- The REMOTE jack enables dash mount level control of the LOW PASS signal, CH3/4 only.

CH3/4 X-OVER slide switch:
- FULL: Sets this pair to full range operation.
- B.P. : In this mode, the HIGH PASS ranges from 50Hz to 150Hz and the LOW
PASS filter ranges from 250Hz to 4KHz, are selected to form a BANDPASS

- HP: Selects the HIGH PASS filter, variable from 50Hz to 4KHz.
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.
