Frequently Asked Questions - C608 Axton

How do I install the C608 amplifier in my vehicle?
Place the amplifier in a well-ventilated area, away from dust and moisture. Secure it firmly using the 4 provided screws, avoiding any contact with the car body to prevent ground loops. Ensure air circulates freely around the ventilation vents.
Which power cable should I use for the C608?
Use a cable with a cross-section of 20 mm² for a length of 5 meters. Install a main fuse of 60 A maximum within 30 cm of the battery. The ground cable must have the same section as the positive cable.
How do I adjust the high-pass and low-pass filters?
The filters are adjustable from 40 to 240 Hz. For the satellites, use the high-pass filter (HPF) between 70 and 150 Hz depending on the speaker diameter. For the subwoofer, use the low-pass filter (LPF) between 50 and 90 Hz. Adjust by ear for a balanced sound.
What should I do if the red PROTECT light comes on?
The red light indicates a protection has been activated (overheating, short circuit, or DC current). Check the speaker and power connections. The amplifier attempts to restart every 5 seconds. Resolve the cause before it operates normally.
How do I correctly set the gains (sensitivity)?
Set the gains to minimum, adjust the source volume to 3/4, then slowly increase the subwoofer channel gain until distortion occurs, then decrease slightly. Then adjust the front and rear gains to balance the sound.
Can I use 2-ohm speakers with the C608?
Yes, the satellite outputs accept a minimum impedance of 2 ohms in stereo, and the subwoofer accepts 2 ohms in mono or 4 ohms bridged. Make sure to respect the RMS power ratings.
How do I connect the RCA inputs if my source does not have a subwoofer output?
Use a Y RCA adapter on the rear outputs of the source to feed the subwoofer input of the amplifier. Ensure the sub output of the source is not filtered to avoid interference with the internal filters.
What is the startup procedure?
Before connecting the +12V cable to the battery, make sure the source is off. Connect the RCA cables, the remote turn-on signal, the speakers respecting polarity, then the ground. Finally, connect the +12V via the main fuse. Turn on the source: the green light should come on.
How to avoid parasitic noise (hum, hissing)?
Use good quality shielded RCA cables. Keep RCA cables away from power cables. Ensure the ground is taken to a clean point on the chassis (no paint or grease). Avoid ground loops by connecting all devices to the same ground point.
What is the recommended crossover frequency for 13 cm speakers?
For 13 cm speakers (coaxial or 2-way) at the front, set the high-pass filter between 80 and 100 Hz. At the rear, between 120 and 130 Hz. These values are indicative; adjust by ear for a pleasant result.

AMPLIFIER LOCATION

1 The mounting location of the power amplifier will have a large effect both on its ability to dissipate the heat generated during normal operation through the heat sink and on the possible triggering of its protective internal overheat protection shut-off circuit. Any mounting position allowing for a good air stream across the cooling fins of the amplifiers heatsink will improve cooling and long-term stability dramatically.

With the AXTON Amplifier Series the most efficient ventilation is achieved when the units are installed standing up!

Therefore select a suitable location that is convenient for mounting and accessible for wiring and offers sufficient ventilation for cooling. As your amplifier features no controls for normal operation, it may be mounted away from the dashboard, i.e. under a car seat or in the trunk. However, make sure the unit is not exposed to excessive dust, direct sunlight, humidity, water, oil or other fluids that may enter the amplifier.

2 The amplifier should be mounted to a solid surface that will ensure a vibration-free mount. Once selected, use the unit as a template for the marking of the mounting holes which should also be pilot-drilled before final securing with the screws provided is carried out.
3 Secure the amplifier using the four screws. Avoids to let the amplifier get in contact with metal parts of the vehicle. This helps to eliminate unwanted ground loops.

WIRING TIPS

Please note: wrong power or signal connections may damage the amplifier and other components connected to it. Therefore, please read this manual carefully before the connection of any power, signal and speaker leads.

The wire routing is critical for noise-free performance. For best results, please follow the general wiring guidelines listed below (for details see sections B, E, F and G of this manual).

1 For audio signal connections you should always use double or triple shielded quality RCA cables.
2 Signal, speaker and power cables should always be kept as short as possible:

⑦Speaker and power cables may easily be cut to fit the actual lengths required.
71 Shielded RCA/signal cables should never be cut and respliced, as they will lose their protective shielding effect in the places where they are cut. If the signal cable is too long, make an S-type loop (never a coil loop) about midway of the cable stretch.

3 Never route any low level/signal cable near or parallel to speaker outputs/speaker cables, amplifier power cables or high energy ignition wires.

4 Use power cable with the recommended cross-section (see section E). Small crosssections are reducing the output power, are causing distortions and may be triggering the overheat protection of the amplifier.

5 Make sure you are using a main fuse protection for the +12V-power input of the amplifier within max. 30 cm of the car battery and power cables with an amperage adequate cross-section and main fuse (for details see section E: „Connecting“).
6 The GROUND/GND cable (-12V) should have the same cross-section as the +12V power cable. Make sure to get a good chassis ground contact, because poor ground contacts are the cause for most power problems with car audio installations.
7 Make sure no power, signal or speaker lines are shorting to chassis ground by using rubber grommets wherever a cable has to pass through any metal part of the vehicle.

Important: Before any wiring, always remove the (+) terminal of the battery to prevent short-circuiting. The last lead to be connected in every installation is always the positive (+) 12 Volt terminal of the battery. Connect this lead only after having completed and checked all other connections.

Axton C608 - WIRING TIPS - 1

CONNECTING THE C608

IMPORTANT: DISCONNECT THE +12V MAIN POWER CABLE FROM YOUR CAR BATTERY BEFORE ANY CONNECTING WORK IS CARRIED OUT!

The recommended power cable cross-section for +12 V (average length 5 m) and ground cable is 20 mm ^2 !

The recommended main fuse value for this amplifier is 60 A!

It is recommended to connect your amplifier as follows:

1 Make sure your head-unit is turned off and the volume control is in its minimum position.

2 RCA outputs of your head unit to respective RCA inputs of your amplifier (see connecting diagrams on pages 23 - 24 of this manual).

Sub pre-outs from head-unit should be fullrange signals because low-pass pre-out signals always affect filtering electronics of amplifier! In case of doubt just ,double' a fullrange front or rear pre-out by using Y-adaptors.

3 Remote lead connection from head-unit to amplifier.

4 Speaker cables to respective speakers or passive crossovers. Make sure to keep correct polarity! ⊕ "to „⊕" and „⊖" to „⊖" All speakers must have a minimum impedance of 2 Ohms!!!

5 Ground connection to chassis ground or -12 V negative battery: If possible ground cable as short as possible and make sure chassis contact is well sand-papered, i.e. clean from any paint, rust or dirt for maximum contact.

In case of problems hook-up your your annplifier directly with the -12 V negative pole or your battery.

6 +12 V power connection to positive battery pole. Do not forget to install a main fuse within 30 cm of car battery (fire hazards)!!!

Do not connect +12 V cable to battery before re-checking every other connection on the amplifier!

Turn-on your head-unit keeping your volume at the minimum. The green status LED on the front of the amplifier should light up now. If not, turn-off your head-unit and recheck all wiring to and from the amplifier for missing or faulty connections.

CONTROLS & ADJUSTMENTS

C608 5-Channel System Amplifier

The AXTON C608 is a powerfully performing 5-channel system amplifier. One single C608 allows for an easy-to-install, speaker-dedicated amplification of a complete 5-channel speaker system, i.e. with two stereo pairs of independently controlled satellite speakers (front and rear) and one mono subwoofer.

The integrated, separately adjustable HIGHPASS and LOWPASS crossover filters of the C608 enable you to drive the connected speakers in the specific frequency range where they will perform best.

Dashboard, door and rear shelf speakers of 10-16cm diameter will never have a good low-end bass reproduction anyway. Therefore the C608 front and rear satellite channels will only be playing in the midbass and mid/high frequency range. This so-called highpass filtered or HPF amplification mode also puts less electrical and mechanical ,strain' on the speaker units, resulting in an increased power handling capacity. The subwoofer output will only receive lowpass filtered (LPF) signals resulting in the subwoofer only playing in the low-end bass frequency range without any unwanted ,smearing' into the mid/high frequencies.

1 CROSSOVER FREQUENCY SETTINGS HIGHPASS FRONTLOWPASS SUB

Before you can effect the respective input sensitivity or gain LEVELs you first have to select the system appropriate crossover frequencies. For best results all crossover adjustments should usually be effected by ear.

For appropriate crossover frequency selection, all tone controls (Bass, Mid, Treble, Sub) and all fader and balance controls etc. on the head unit have to be brought to their neutral or center position! The „Loudness” function should also be deactivated.

Depending on the actual cone surface area, voice-coil diameter and the rated power handling of the 'satellites' it is recommended to set the high-pass crossover / cut-in frequency between 40 and 240 Hz.

If the satellite highpass frequency is set too low, the mid-bass reproduction, will be increased, but at the same time the power handling capacity of the satellites will decrease. If the highpass frequency is set too high, the mid-bass reproduction will become ,thinner' while the power-handling capacity of the satellites will increase.

As a general guideline, below you find a practice-proven list for appropriate satellite HPF crossover / cut-in frequencies covering the most widely used dashboard, door and rear-shelf speaker diameters:

Front Satellite SpeakersHIGHPASS FREQ.
10 cm∅ Coaxials or 2-Way Compos90-120 Hz
13 cm∅ Coaxials or 2-Way Compos80-100 Hz
16 cm∅ Coaxials or 2/3-Way Compos70 - 80 Hz
Rear Satellite SpeakersHIGHPASS FREQ.
10 cm∅ Coaxials or 2-Way Compos100-150 Hz
13 cm∅ Coaxials or 2-Way Compos120-130 Hz
16 cm∅ Coaxials or 2/3-Way Compos100-130 Hz

Satellite rule 1 The better sounding satellite system should always be installed in the front of the vehicle.

Satellite rule 2 Based on identical speaker diameters and comparable engineering quality of the front and rear satellites, the crossover cut-in frequency of the front satellites should usually be set lower than the highpass frequency of the rear satellites.

The LPF / LOWPASS SUB cut-off frequency for the subwoofer should usually be set in between 50 and 90 Hz. Adjust the LOWPASS SUB control in such a way that the bass reproduction will be stiff and rich, while still delivering a good and solid low-end bass.

Subwoofer Generally, setting the LPF lowpass cut-off guideline frequency too low will result in a weak and uncontoured bass response. Setting the LPF control too high tends to give the subwoofer a ,booming' sound.

High- & lowpass When selecting the high- and lowpass system tip frequencies of a sound system, it is recommended to ,leave a gap' between the subwoofer LPF cut-off frequency and the satellite HPF cut-in frequencies. Such a ,gap' between the LPF and HPF settings can be helpful to compensate for much of the midbass resonance (around 100 Hz) otherwise occurring in most vehicle environments.

2 Sensitivity Adjustments and System Matching GAIN FRONT, REAR and SUB

To reach a maximum of dynamic response from your individual head unit / amplifier / speaker combination, it is important to set the respective input sensitivity controls (LEVEL) correctly. On the one hand the sensitivity determines the actual signal-to-noise ratio. On the other hand the sensitivity also controls the maximum distortion-free sound pressure level (SPL) possible with your specific car audio system.

It is recommended to effect the sensitivity adjustments and system GAIN matching in the same sequence as listed below:

7 Set all tone controls (Bass, Mid, Treble, Sub) on the head-unit as well as all fader and balance controls to neutral. The „Loudness“ option should be in the „Off“ position, too.
Set all 3 GAIN controls of the C608 to their lowest position.
7 Turn-on your head-unit and turn-up the volume control to approximately 3/4 of full volume and start playing a well recorded, dynamic piece of music.
7 Slowly turn up the GAIN control of 5CH until you can hear distorted bass sounds. Slowly decrease the GAIN SUB control to the point where the distortions have just disappeared.
Now you reduce the main volume level on the head-unit to a medium listening level.
7 Start turning up the FRONT GAIN control (1CH/2CH) clockwise until you have reached a good tonal balance between the front satellites and the subwoofer. A slight attenuation of the bass range should be preferred, as this will be compensated later by normal driving noises.

7 Start turning up the REAR GAIN control (3CH/4CH) clockwise until you feel to you have reached an appropriate ,rear fill' in the back of the car, so that the overall in-car sound becomes smooth and homogenous.

Finally, you may want to do some fine-tuning on the different highpass and lowpass frequencies selected. It is recommended to start fine-tuning with the subwoofer (LOWPASS SUB) frequency. Proceed - if necessary - with the front satellites (HIGH-PASS FRONT) and finish the frequency adjustments with the rear satellites (HIGHPASS REAR).

IMPORTANT: All advice on controls and adjustments of this manual section is based on the assumption that you are also thoroughly acquainted with all the requirements and features of the entire audio equipment - especially the head-unit and the speakers - connected to this amplifier!
