ZEUS HIGH PERFORMANCE AMPLIFIERS
The Zeus ZRX Series products have been designed to a very high level of performance, with features unavailable in
any other product. All of the amplifiers have variable crossovers built in, with added touches such as subsonic
filter, bass equalization and a remote Level control module(some models) that allows subwoofer Level control from
the drivers seat.
To ensure years of listening pleasure, all amplifiers have a built in diagnostic mode that will detect shorted speaker
leads, low impedance, dangerous high temperatures, DC shorts and will shut down the amp to prevent serious
damage.

GENERAL INSTALLATION PROCEDURE
System Design
The success of any car stereo system relies on several factors, such as the system design, execution of the installation, and system setup. Please
remember that any system is only as good as its weakest link.
Please remember that higher power systems are not necessarily useful purely for high sound pressure levels, but also to establish a headroom capability, to
reproduce musical peaks cleanly without distortion. Lower power amplifiers will clip earlier than their more powerful cousins, and cause loudspeaker failure when
overdriven, due to the harmonics generated by a clipped signal, thus overheating voice coils.
Amplifiers should be mounted with the fins running horizontally for best convection cooling, to minimize overheating. Purchase the best quality RCA cables you can
afford, for reliability and less engine noise interference in the audio system.
Installation
WOOD
It is highly recommended that the amplifier be mounted to a board of MDF or other solid
structure using the 4 mounting screws provided. Avoid mounting the
amplifier to metal as this can introduce noise and other unwanted issues. When mounting
the amplifier, ensure that it is mounted HORIZONTALLY, as shown in the diagram above, for
optimal heat dissipation. Mounting amplifiers to speaker enclosures is not recommended as
this can cause damage to the amplifier components. When choosing a location for
mounting the amplifier, ensure that you check for clearance from wires, gas tank, electrical
devices and brake lines etc.
ZEUS
General:
Run the wiring so that RCA cables are at least 18“ away from power and speaker cables. Keep RCA cables away from electrical devices in the vehicle that can cause
electrical noise, such as electric fuel pumps, emission control modules and other on-board electronic modules.
Power and ground connections(see the features matrix on page 7 for proper gauge cables per amplifier):
Use a sufficient gauge power cable and ground cable using the chart below as reference to what size wire you require. Zeus series amplifiers require at least 4 gauge
power wire. In a multi amplifier system, add the total value of the manufacture recommended fusing to get your total system amperage. Some applications may
require multiple runs of power wire to meet the system requirements. In multi amplifier systems it is advisable to mount a large enough fuse right at the battery, and
run one or multiple +12 volt power cables to a fused distribution block near the amplifiers. It is then a simple matter to connect the +12 volt terminal of each amplifier
to the distribution block. During this process, please ensure that the main power fuse is removed to avoid shorting the electrical system. The main fuse must be within
12” of the vehicles battery.
Ground each amplifier with as short a ground lead as possible directly to the vehicle chassis using at least 4 gauge wire or equivalent to the size of the amplifiers’
power wire. Use a ground distribution block, if you wish, but it is extremely important to keep the main ground lead from this distribution block to the chassis as short
as possible , not more than 12“. The ground connection integrity to the chassis is very important, and the best way to achieve a good, solid electrical and mechanical
contact is to use a large round crimp lug, crimped and soldered to the ground cable. The next step is to scrape the paint off the vehicle chassis , slightly larger than
the ground lug, at the connection point. Drill a clearance hole in the chassis, the same size as the lug hole, and use a bolt, spring washer and nut to securely fasten
the ground lug. Use petroleum jelly to coat the bolt/lug connection, to prevent oxidization with time.
TIP: Use the same approach when installing head units, equalizers or any audio equipment for that matter - run short individual grounds from each piece directly to
the vehicle chassis, to minimize ground loops and system noise. All power, ground and speaker connections should be crimped and soldered for reliability. Make sure
that none of the cable insulation can chafe against exposed metal in the vehicle, causing short circuits to the chassis.

Safe connection sequence:
After all cables are run, connect speaker wires to the speakers and amplifiers, then run and plug in RCA cables. Next, connect all power, ground, and remote turn on
leads. Now connect all +12 volt cables to the amplifier/s and distribution blocks and fuse holders. Finally, connect the main +12 volt cable to the battery, with the main
fuse removed, and we are almost ready to power up the system.
Power up the system:
The following procedure may seem like overkill, but there is nothing more frustrating when turning on a system for the first time, and it does not work properly
immediately.
First, make sure the head unit is off, and turn all level controls to minimum (counterclockwise), including the head unit volume control. Set all equalizers to 0 dB (no
boost), and all crossover frequency controls at approximate frequencies, as recommended by the loudspeaker manufacturer. Set all input selector and crossover
switches as required for the application. Remove all amplifier fuses, and insert the main fuse at the battery. If the fuse does not blow, you can insert the fuse in one of
the amplifiers, and we are ready to turn on the system. Turn the head unit on, insert a CD, or select a radio station, and increase the head unit volume control. If the
system sounds fine, turn off the head unit, and install fuses in the remaining amplifiers, one by one, till the complete system is powered up and functioning properly.

2 or 3 CHANNEL SYSTEM
Here we show how to use the 4 channel amplifiers as a 3 channel unit by taking
advantage of the mono bridging capability of all Hifonics amplifiers.
Switch setting checklist:
- 1/2CH X-OVER: FULL
- 3/4CH X-OVER: LPF
The following example shows how to create a 3 channel system by mono
bridging channel pair 3 / 4. In order to create a 2 channel system, simply follow
the example to also mono bridge channel pair 1 / 2.
Interconnect cable checklist:
- Connect the inputs of channel pair 1/2 to a suitable stereo source, e.g. a head
unit with good quality RCA cables.
- A MONO signal source is required to bridge channel pair 3/4, such as would be
available from the mono sub bass output of an active crossover, whether
standalone, or built into a head unit or equalizer. If you only have 1 set of RCA
outputs from your headunit, you can simply connect those to the inputs for ch
1/2 and switch the MODE to 2ch. The amplifier will auto sum the signal and
provide mono output for bridged channels 3/4 once the X-OVER is switched to
LP/BP.
Important: Do not be tempted to connect the hot, or positive outputs, from any
source together to obtain a mono signal, as this could very well damage the
output stage of that source.
- It is necessary to feed the SAME signal to both left and right inputs via a Yadapter RCA cable.
- Connect the mono speaker positive terminal to the LEFT +, and its negative
terminal to RIGHT - as shown.
Channels 3/4:
- HI PASS: N/A
- LPF: 11 o’clock
TIP: If you are using the mono sub bass output of an active crossover, there is
nothing wrong with switching in the low pass filter in these amplifiers for a
steeper low pass rolloff.
Level control checklist:
- Refer to the section “Setting up systems after installation for best performance”
Minimum final loudspeaker impedances:
- 2 ohm per channel in stereo mode.
- 4 ohm mono bridged.

SETTING UP SYSTEMS AFTER INSTALLATION FOR BEST PERFORMANCE
ZRX500.2 / ZRX1200.2 / ZRX600.4 / ZRX1000.4 / ZRX2000.4
General:
At this point you are ready to get more specific on the settings for your amplifier.
High Pass:
-When in Hi Pass operation, this setting acts as a low frequency cut off for your system reproduction. The point that you set it at cuts off any frequencies from reproduction beyond this
point. The 12 o’clock position is a great starting point. EXAMPLE: If you adjust the High Pass to 100Hz, the amplifier will not play frequencies below 100Hz but will play frequencies from
100Hz to the highest frequency the amplifier is capable of reproducing.
-When in Low Pass/Bandpass operation, this setting acts as a low frequency cut off for your system reproduction aka Subsonic Filter. The point that you set it at cuts off any frequencies
from reproduction beyond this point. The 12 o’clock position is a great starting point. EXAMPLE: If you adjust the High Pass to 60Hz, the amplifier will not play frequencies below 60Hz
but will play frequencies from 60Hz to the chosen Low Pass frequency.
-When in Flat/Full operation, the Low Pass crossover is bypassed.
Bass EQ:
This setting is a fixed bass boost at 45Hz that is variable from 0-12dB. This feature provides impact to your bass, but if not adjusted correctly, it can be over used and cause damage to
your speakers and amplifiers. It is best to slowly turn this setting clockwise until the desired punch is felt. It is not recommended to exceed the 12 o’clock position unless listening at a low
volume or a low recording quality as this can result in high distortion and possibly clipping.
Low Pass:
The Low Pass control acts as a ceiling and doesn’t allow frequencies to the right of the desired setting to be reproduced. Turning the potentiometer all the way to the right is a great
starting point. EXAMPLE: If you adjust the Low Pass to 120Hz, the amplifier will not play frequencies above 120Hz but will play frequencies from 120Hz to the chosen Hi Pass or
Subsonic frequency.
-When in Hi Pass operation, this setting is bypassed.
Level Control Setup:
Ensure that the Level is turned completely to the left prior to turning the system on. Next you should insert a CD or cassette that you are familiar with to use as a reference, and turn the
head unit volume control to about 80% of its full setting. The system sound level will of course be very low, and the following procedures will help you to match the amplifier input
sensitivities properly to the head unit output signal level.
It is important to match the amplifier LEVEL input sensitivity to the Radio/CD output sensitivity. This can be located in the Radio/CD manual.
If the Radio/CD output sensitivity is 2 volts, then adjust the amplifier LEVEL input to 2 volts.
If you are not sure what the Radio output sensitivity is, follow these general guide lines:
Turn the level control up slowly, till you hear distortion, then back off a few degrees on the control. If at any point your amplifier goes into protection, you will need to turn the Level to the
left a bit and then try again. If you reach a point where the output does not increase, stop turning the Level control to the right as the amplifier/speaker combo has reached its maxx
output in this application.
2 or 3 way active systems (all):
Always start with the bass, or low frequency amplifier as a reference, by turning its control up to the point where distortion is audible, and back it off some.
Now adjust the level control for the highs or tweeter channels in a 2 way active system, to balance the highs to lows.
In a 3 way active system, match the midrange level to the bass, and then the highs to the midrange and bass. It may be necessary to perform a few iterations of the midrange and highs level
control settings to achieve a satisfactory sound balance.

General:
At this point you are ready to get more specific on the settings for your amplifier.
Subsonic:
This setting acts as a low frequency cut off for your system bass reproduction. The point that you set it at cuts off any frequencies from reproduction beyond this point. The 12 o’clock
position is a great starting point. EXAMPLE: If you adjust the Subsonic to 25Hz, the amplifier will not play frequencies below 25Hz but will play frequencies from 25Hz to the chosen Low
Pass frequency.
Bass EQ:
This setting is a fixed bass boost at 45Hz that is variable from 0-10dB. This feature provides impact to your bass, but if not adjusted correctly, it can be over used and cause damage to
your subwoofers and amplifiers. It is best to slowly turn this setting clockwise until the desired punch is felt. It is not recommended to exceed the 12 o’clock position unless listening at a
low volume or a low recording quality as this can result in high distortion and possibly clipping.
Low Pass:
The Low Pass control acts as a ceiling and doesn’t allow frequencies to the right of the desired setting to be reproduced. The 12 o’clock position is a great starting point. EXAMPLE: If you
adjust the Low Pass to 80Hz, the amplifier will not play frequencies above 80Hz but will play frequencies from 80Hz to the chosen Subsonic frequency.
Level Control Setup:
Ensure that the Level is turned completely to the left prior to turning the system on. Next you should insert a CD or cassette that you are familiar with to use as a reference, and turn the
head unit volume control to about 80% of its full setting. The system sound level will of course be very low, and the following procedures will help you to match the amplifier input

output in this application.

TROUBLESHOOTING A SYSTEM
The key to finding the problem in a misbehaving sound system is to isolate parts of that system in a logical fashion to track down the fault.
Description of the PROTECT system built into all Hifonics amplifiers
The diagnostic system will shut down the amplifier, until reset by turning the head unit off, and back on. This state of affairs will be indicated by the front panel PROTECT
LED lighting up under the following conditions:
1 - A sort circuit on the loudspeaker leads.
2 - An internal amplifier fault that causes a DC offset on the loudspeaker output.
Should the amplifier go into protect mode, simply disconnect all RCA and speaker leads, while keeping +12 volt, power ground and remote leads connected.
1. Now turn the amplifier back on, and if the diagnostic LED lights, the amplifier has an internal fault.
2. If not, plug the RCA cables back, and reset the amplifier. If it goes into diagnostic now, the fault lies in the input, either with bad cables or source unit.
3. If the amplifier seems fine with RCA cables plugged in, connect the speakers, one at a time, and if one of the speakers or its wiring is faulty, it will activate the diagnostic
system.
Amplifier heatsink overheating
The amplifiers will shut down when the heatsink temperature reaches 80 degrees centigrade, and turn back on once the unit has cooled down below that point.
Causes of overheating:
1 - Inadequate cooling - relocate or remount to provide better natural airflow over the fins.
2 - Driving high power levels into low impedances - back off on the volume control, and/or make sure you are not loading the amplifier with less than the recommended
loudspeaker impedance.
Low output power
1 - Check that level controls have been set up properly.
2 - Make sure that the battery voltage, as measured at the amplifier’s +12 volt and ground terminals, is 11 volts or more.
3 - Check all +12 volt and ground connections.
Fuses blowing
1 - The use of loudspeaker impedances below the recommended minimums will draw more current - check.
2 - A short on the main +12 volt cable from the battery to the vehicle chassis will cause the main fuse to blow.
3 - If an amplifier fuse blows continually, with only +12 volt, ground and remote leads connected, the amplifier may be faulty.
System does not turn on
1 - Check all fuses.
2 - Check all connections.
3 - Measure the +12 volt and remote turn on voltages at the amplifier terminals. If these are non existent or low, take voltage measurements at fuse holders, distribution
blocks, the head unit’s +12 volt and remote leads to localize the problem.
Noise problems
System noise can be divided into two categories, hiss, and electrical interference.
Hiss, or white noise
1 - High levels of white noise usually occurs when amplifier level controls are turned up too high - readjust according to the procedures in section ”Setting up systems after
installation for best performance”
2 - Another major problem that can cause excessive hiss, is a noisy head unit - unplug the amplifier input RCA cables, and if the hiss level reduces, the source unit is at fault.
Electrical interference
The inside of an automobile is a very hostile electrical environment. The multitude of electrical systems, such as the ignition system, alternator, fuel pumps, air conditioners,
to mention just a few, create radiated electrical fields, as well as noise on the +12 volt supply and ground. Remember to isolate the problem - first unplug amplifier input RCA
cables, if the noise is still present, check the speaker leads, if not, plug the RCA’s back, and investigate the source driving the amplifier, one component at a time.
A ticking or whine that changes with engine RPM:
1 - This problem could be caused by radiation pickup of RCA cables too near to a fuel pump or a distributor, for instance, - relocate cables.
2 - Check that the head unit ground is connected straight to the vehicle chassis, and does not use factory wiring for ground.
3 - Try to supply the head unit with a clean +12 volt supply directly from the battery +, instead of using a supply from the in dash wiring/fusebox.
A constant whine:
This type of noise can be more difficult to pinpoint, but is usually caused by some kind of instability, causing oscillations in the system.
1 - Check all connections, especially for good grounds.
2 - Make sure that no speaker leads are shorting to exposed metal on the vehicle chassis.
3 -RCA cables are notorious for their problematic nature, so check that these are good, in particular the shield connections.
