HIFONICS ZEUS POWER ZXR800/4E

Safety Instructions

General Safety:

• This device is designed for 12V vehicle electrical systems only. Improper use may cause fire, injury, or electric shock.
• Do not operate the sound system in a way that distracts from safe driving. Stop the vehicle in a safe location before performing any operations.
• Adjust volume to a level where you can still hear exterior noises. Prolonged exposure to loud music can cause hearing loss and impair your ability to perceive warning signals.
• Do not cover cooling vents or heat sinks to prevent overheating and fire hazards.
• Never open the device, as this can lead to injury, fire, electric shock, and void the warranty.
• Replace fuses only with those of the same rating to avoid fire and electric shock hazards.
• If a malfunction occurs that cannot be resolved, discontinue use and consult an authorized dealer.
• Installation and interconnection should be performed by skilled personnel.
• Disconnect the vehicle's battery ground connection before installation to prevent short circuits and electric shocks.
• Choose an installation location with sufficient air circulation, avoiding high humidity and dust.
• Mount the device and components securely to prevent them from becoming loose and causing injury.
• Ensure all terminals are correctly connected to prevent fire hazards and device damage.
• Do not damage vehicle components, wires, or cables during installation.
• Do not install audio and power supply wires together to avoid interference.
• Ensure cables are not caught in close-by objects, especially near the steering wheel, gear lever, or brake pedal.
• Do not splice electrical wires; use appropriate distribution blocks.
• Do not use brake or steering system bolts/nuts as ground points.
• Avoid bending or squeezing cables with sharp objects. Protect cables passing through metal sheets with rubber grommets.
• Keep small parts and jacks away from children to prevent injuries.

Disposal/Recycling:

Dispose of electronic devices at a suitable recycling facility in accordance with local regulations. More information is available at www.audiodesign.de/entsorgung.

Technical Specifications

* Prevents error messages in the vehicle diagnostic system.

Intended Use:

This product is designed for use in a vehicle with a 12V on-board voltage and negative ground as an audio signal amplifier. Any other use may lead to product damage.

Mechanical Installation

• Avoid damaging vehicle components like airbags, cables, board computer, seat belts, or the gas tank.
• Ensure the chosen location provides sufficient air circulation for the amplifier. Do not mount in small sealed spaces without air circulation or near heat-dispersing parts.
• Keep all cables as short as possible to avoid losses and interference.
• Use self-tapping screws (not included) for installation.

Fastening:

A diagram shows the amplifier with four mounting holes, indicating where screws should be placed for secure mounting.

Caution: Before installation, disconnect the vehicle's battery ground connection.

Electrical Interconnection

Before Connecting:

• Use appropriate wiring kits from car audio retail stores. Ensure correct cable cross-section and fuse rating.
• Clean and remove rust/oxidation from battery and ground connection points.
• Ensure all screws are tightened after installation to prevent malfunctions.

Connections:

1. GND: Connect the GND terminal to a suitable ground point on the vehicle's chassis. Ensure a stable and safe connection to the battery's negative pole. Use a ground wire with sufficient cross-section, same size as the +12V wire.
2. REM: Connect the turn-on signal or remote signal from your head unit to the REM terminal of the amplifier using a 0.5 mm² cable. This will turn the amplifier on/off with the head unit.
3. +12V: Connect the +12V terminal to the vehicle's battery +12V pole using a suitable cable (refer to table for recommendations).
4. FUSES: Slot for device fuses (2 x 40 A). Replace defective fuses only with identical ones.
5. ADDITIONAL CABLE FUSE (NOT INCLUDED): Install an extra fuse for the +12V power cable near the battery (max. 30 cm distance). Fuse size must match the cable cross-section. This fuse protects the cable, not the amplifier, against short circuits.

Cable Cross-Section Table:

A table shows recommended minimum cable cross-sections in mm² based on fuse value in Amperes and cable length in meters.

Caution: Replace defective fuses only with new ones of the same type and rating.

Description of Operation

• POWER/PROTECT (LED): Green LED indicates operation; Red LED indicates a malfunction (refer to Troubleshooting).
• AUTO TURN-ON: If the head unit lacks a REM signal, use this function with HIGH LEVEL INPUT. The amplifier detects a 6V DC offset to turn on. It switches off when the head unit turns off.
• INPUT MODE: Select 2CH or 4CH stereo signals. Fader function is effective only in 4CH mode. In 2CH mode, FRONT signal is routed to REAR.
• FREQ. (FRONT & REAR): Adjusts the crossover frequency from 50 Hz to 5000 Hz, depending on the X-OVER MODE setting.
• X-OVER MODE (FRONT & REAR): Sets the operating mode: FULL (Full Range), HP (High Pass, limited downwards by FREQ), LP (Low Pass, limited upwards by FREQ).
• LEVEL INPUT (FRONT & REAR): Adjusts input sensitivity. Set head unit volume to 80-90%, then slowly turn the LEVEL INPUT clockwise until slight distortion is heard, then back off slightly.
• HIGH LEVEL INPUT (FRONT & REAR): Use if the head unit lacks RCA pre-amp outputs. Connect head unit speaker cables to the included harness.
• LINE INPUT (FRONT & REAR): For connecting RCA cables if the head unit has RCA pre-amp outputs.
• BASS BOOST (REAR): Adjusts bass boost from 0 to +12 dB at 45 Hz for the REAR channel pair when using a subwoofer. Use with caution to avoid distortion.

Application Examples

Diagrams illustrate various wiring configurations for 4-channel and 2-channel operation, showing connections from the head unit to the amplifier and speakers, including RCA and High Level inputs.

Assignment Tables:

Tables show the mapping between Head Unit RCA Outputs/Speaker Outputs and Amplifier RCA Inputs/High Level Inputs for different configurations.

Trouble Shooting

• NO FUNCTION / POWER LED NOT ILLUMINATED: Check fuses, +12V connection, REM signal, and AUTO TURN-ON switch. Verify voltage with a voltmeter.
• POWER LED ON, BUT NO SOUND FROM SPEAKERS: Check RCA/speaker cable connections, integrity of cables, speaker functionality (test with 9V battery), amplifier settings (input mode, crossover), and head unit settings (fader, balance, mute, filters, source).
• DISTORTION OR HISSING NOISE: Adjust input level, Bass Boost, loudness, and EQ settings on the amplifier and head unit.
• ENGINE SPEED DEPENDENT NOISE: Ensure RCA cables are laid separately from power cables. Check amplifier ground connection and vehicle battery ground cable conductivity.
• ACTIVE TWEETER DISTORTED OR CRACKED: Ensure crossover mode is set to High Pass (HP/HPF). Adjust high pass filter to prevent damage to tweeters from low frequencies.
• AMPLIFIER PROTECTIVE CIRCUIT / PROTECT LED: Check for short circuits on speaker cables, correct load impedance, proper power cable cross-section, and amplifier overheating. Ensure adequate air circulation for the heatsink.

Caution: Troubleshooting steps refer to the entire system. Device features may vary.
