PRECAUTIONS
-
This unit is designed for negative ground 12V DC operation only.
-
Avoid installing the amplifier where:
– It would be subject to high temperature, such as from direct sunlight or hot air from the heater
– It would be exposed to rain or moisture.
– It would be subject to dust or dirt. -
If your car is parked in direct sunlight and there is a considerable rise in temperature inside the car, allow the amplifier to cool off before operation.
-
When installing the unit horizontally, be sure not to cover the heatsink fins with the floor carpet.
-
If this unit is placed too close to the car radio, an interference may occur. In this case, separate the amplifier from the car radio.
-
This power amplifier employs a protection circuit to protect the transistors and speakers if the amplifier malfunctions. Do not attempt to test the protection circuits by covering the heatsink or connecting improper loads. Do not use the amplifier with a weak auto battery as its optimum performance depends on a normal battery supply voltage.
-
For safety reasons, keep the volume of your car audio system moderate so that you can still hear normal traffic sounds outside your car.
INSTALLATION
- First, ensure the mounting location is free of dirt and dust and that there is enough ventilation in order to achieve optimum performance and avoid overheating when the amplifier is in use.
- Keep the wire connections as short as possible with sufficient length in order to minimise any power losses and provide a higher audio output of the system.
- Where possible route all power and speaker wiring through any existing wire channels within the vehicle in order to ensure wiring does not pass through sharp edged metal.
- Make sure all cables are away from any ignition cables or modules in the boot and under the key dashboard components in order to avoid any interference.
- Add a fuse to the (+) power cable in a distance of not more than 30cm from the positive battery pole.
- Ensure the power cable is as short as possible.
WIRING INSTRUCTIONS
POWER CONNECTION
The battery terminal (+12V) must be connected directly to the positive
terminal of the vehicle battery to provide an adequate voltage source and
minimize noise. Connecting the battery terminal lead to any other point (such
as the fuse block) will reduce the power output and may cause noise and
distortion. Use only #8 gauge or thicker (smaller gauge #) wire for this lead
and connect it to the terminal of the battery after all other wiring is
completed.
GROUND CONNECTION
The ground terminal (GND) connection is critical to the correct operation of
the amplifier. Use a wire of the same gauge as the power connection (#8 or
thicker) and connect it between the ground terminal (GND) of the amplifier and
a metal part of the vehicle close to the mounting location. This wire should
be as short as possible and any paint or rust at the grounding point should be
scraped away to provide a clean metal surface to which the end of the ground
wire can be screwed or bolted.
SPEAKER CONNECTIONS
Depending on the type and number of speakers used with the amplifier, wired
them to the speaker terminals as per the appropriate wiring diagram.
For most applications 18 gauge wire should be used for the speaker leads but
in no case thinner than 20 gauge. For leads in excess of 10 feet 16 gauge is
recommended.
When wiring the speakers, pay careful attention to the polarity of the
terminals on the speakers and make sure they correspond to the polarity of the
corresponding terminals on the amplifier. Do not ground any speaker leads to
the chassis of the vehicle.
REMOTE TURN-ON CONNECTION
The amplifier is turned on by applying +12V to the remote turn-on terminal
(REM). The wire leading to this terminal should be connected to the Remote Out +12V’ lead from the car stereo which will provide the +12V only when the car stereo is turned on. If the car stereo does not provide anRemote Out
+12V’ lead, the remote turn-on lead may be wired to an “Accessory” or “Radio”
terminal in the car’s fuse block. This will turn the amplifier on and off with
the ignition key, regardless of whether the car stereo is on or off. The
remote turn-on lead does not carry large currents, so a #20 gauge wire may be
used for this application.
FUSE
The amplifier is equipped with a plug-in auto fuse which helps protect the
amplifier against faulty conditions. Do not use a fuse with a higher value and
never bridge the fuse, as this may lead to the warranty of the amplifier being
denied/void.
FUSE REPLACEMENT
If the fuse blows, check the power connection and replace the fuse. If the fuse blows again after replacement, there may be an internal malfunction. In this case, consult your dealer.
WARNING:
Use the specified fuse. Use of a higher fuse may cause serious damage.
PROTECTION CIRCUIT:
This amplifier is provided with a protection circuit which operates in the
following cases when:
- The unit is overheated.*
- The speaker terminals are short-circuited.
*THERMAL PROTECTION:
As these amplifiers are Class A/B, they can tend to get hot when being used
for long periods of time.
In the case that the amplifier goes into `thermal protection’, please provide
better airflow around the unit.
POWER CONNECTION LEADS
to a metal part of the car
NOTES ON THE POWER SUPPLY
- Connect the +12V power input lead only after all other leads have been connected.
- Be sure to connect the ground wire of the unit securely to a metal part of the vehicle.
- A loose connection may cause a malfunction of the amplifier.
- Place the fuse in the power supply lead as close as possible to the car battery.
- The unit is turned on by applying +12 Volts to the REM (Remote In). This terminal does not draw heavy current like the main Power Terminals so a thinner connecting wire is acceptable. Standard 18 GAUGE is fine and the standard colour is blue. If the radio is equipped with a Power Antenna control wire, it can drive this terminal. If the Power Antenna wire is already in use, you can still splice into it. With this method, the unit will turn on automatically with the radio. Use the power supply lead with a fuse attached whose value is the same as the original fuse inside the amplifier.
- During a full power operation, maximum current will run through the system, therefore, make sure that the leads to be connected to the +12V and GND terminals of the unit respectively must be larger than 10 Gauge (AWG.10).
IN CASE OF FAULTS
NO FUNCTION
The connection cable is not connected correctly (terminal BATT/GND /REM).
Ensure that all connections, mechanical contacts, and wire jackets have been
removed. The fuse might be defective – pay attention to the correct value of a
new fuse!
NO SOUND
Speaker cable or RCA plugs are not connected correctly.
NO SOUND / RED LED PROTECTION SHINES:
The plus and minus wires of the speaker cable shorted, thus creating a short
circuit. If you use a 2 Ohm speaker in stereo mode, turn the gain control to
“min” until the operation is free of trouble.
POOR SOUND QUALITY (DISTORTIONS)
The speakers are overloaded, therefore turn down the volume level and check
the volume control positions.
NO STEREO AND A WEAK BASS
Left and right speaker cables (+) and (-) are out of phase.
OPERATION
After the amplifier has been installed and all connections have been made
carefully and securely, turn the radio on so that the amplifier is switched on
automatically. After a short power-on period, the amplifier reaches its full
performance.
Now turn up the volume slowly using the volume control of the radio. If there
is no sound or only a distorted replay, switch off the radio immediately, the
amplifier will also switch off automatically – and check if all connections
have been made correctly.
POWER = LED POWER INDICATOR
After the correct connection order of the three power terminals, the LED
indicator shines green and goes out when is off.
PROTECT = LED PROTECTION INDICATOR
This unit is equipped with an overload protection function. Immediately upon
overloading (due to short circuit or much increased temperature) the overload
protection is activated, and the red LED indicator is shining. This means the
amplifier is protected.
LEVEL CONTROL
The input level control allows the system to work well within a wide range of
output levels. Choose the adjustment in the way that you achieve a sound
without any distortion.
As a guideline the following procedure is recommended:
If you use several amplifiers, the adjustment has to made for each set
separately. Tune the volume control of your car to 2/3rds of the maximum
volume. Now turn the gain control of the amplifier from MIN’ toMAX’
direction until you can hear distortions. Then turn the level control a little
back to `MIN’. The gain control adjustment is finished.
ATTENTION – If you use 2 Ohm speakers in stereo mode, turn the gain control to `MIN’ direction, until the operation is free of trouble.
INTERFERENCE & NOISE
All cables are sources of interference and noise. The power cable and RCA audio cable are very prone to interference; the remote cables are less prone. The interference can be caused by the generator (piping), ignition (cracking) or other car electronic parts. Most of these problems can be eliminated by correct and careful cabling. In doing so, these are the following guidelines:
- Use only an RCA audio cable for the wiring between the amplifier and RCA output of the radio.
- Lay the signal, speaker and power cables separately with enough distance from one another and also from each other car cable. If not possible, you can lay the circuit and ground cable together with the serial cables. Audio and speaker cable should be as far away from these as possible. The REM cable to the automatic antenna output of the radio can be laid together with the signal cables.
- Avoid ground loops by laying the ground wiring of all components to a centre point in a star-like way. You can find the best central point in measuring the voltage directly at the battery. Now compare this voltage value with the chosen ground point and the (+) terminal of the amplifier. If the measured voltage is only less different, you’ve found the correct central. Otherwise, you have to look for another point. You should measure with the ignition being switched on and additionally switched on other electronics (rear window heating and light). If there are pickups from external electrical sources into the speaker cables, divide the core leads and twist them together.
- If there are noises from the car electronics, add a noise suppression choke to the power wiring.
- If there are humming noises, use thicker ground cables or add further ground cables to the chassis.
- To reduce contact resistance and bad/loose contacts, please tin the cable ends or use multi-core cable ends, spade terminals or others. Note – plated spade terminals are free of corrosion and have the lowest contact resistance.
- Should any of these measures have no success, the use of a ground loop isolator may solve the problem. If the problem persists, contact a certified car audio installer.

ZQA6.8 / ZQDSP12 – HIGH END DSP
OPERATION
When the switch is toggled to DC, the DSP is automatically switched for high level inputs. When switched to REM, the output (REM OUT) of the DSP must be connected to the input connector (REM IN) of the amplifier to work. After a few operations turning the DSP on and off, the DSP has direct current and the switch must be turned to REM IN to control the switch gear.
The product has one REM OUT option and can be connected with the REM input of another amplifier to control the DSP with an externally powered amplifier. If used in this way, please ensure the RCA low level output connector is connected to the external amplifier system. Be sure to use the REM OUT connector of this machine to control the REM Input of the external amplifier, otherwise, it may cause overpowering and result in a fire.
