• Clean the equipment with a dry cloth.
• Comply with all applicable disposal laws and separate plastic and paper/cardboard during packaging disposal.
• Keep plastic bags out of the reach of children.

FOR DEVICES DESIGNED TO BE CONNECTED TO THE MAIN POWER SUPPLY:

• ATTENTION: If your equipment has a power cord with a grounding plug, it must be connected to a wall outlet with a ground connection. Never remove the grounding plug from the power cord.
• If your equipment has been exposed to extreme temperature changes, allow it to reach room temperature before turning it on. Otherwise, moisture and condensation may damage the equipment.
• Before plugging in the equipment, make sure that the voltage and frequency of the power outlet match the specifications of the equipment. If the equipment has a voltage selector, only connect it to the power outlet if the values match. If the power cord or adapter does not fit your outlet, contact an electrician.
• Do not step on the power cord. Make sure it is not pinched at the outlet, adapter, or equipment connection.
• Keep the power cord or adapter within reach and disconnect the equipment from the power supply when not in use or when cleaning it. Always unplug the cord or adapter by pulling the plug or adapter, not the cord. Never touch the cord or adapter with wet hands.
• Avoid frequently turning the equipment on and off, as this can reduce its useful life.
• IMPORTANT: Only replace fuses with those of the same type and rating. If a fuse repeatedly blows, contact an authorized service center.
• To completely disconnect the equipment from the power mains, unplug the power cord or adapter from the outlet.
• If your device has a Volex power connector, the mating Volex connector must be unlocked before it can be removed. Be careful when laying cables, as the equipment can slide or fall if the power cord is pulled.
• Unplug the power cord or adapter before an extended period of disuse or in case of lightning strike risk.
• Only install the equipment when it is disconnected from the power source.
• To prevent damage and overheating, qualified personnel should regularly clean and service the equipment depending on ambient conditions like dust, nicotine, and fog.

If the product contains the following symbols, please, read carefully:

CAUTION: To reduce the risk of electric shock, do not remove cover (or back). There are no user serviceable parts inside. Maintenance and repairs should be exclusively carried out by qualified service personnel.

The warning triangle with lightning symbol indicates dangerous uninsulated voltage inside the unit, which may cause an electrical shock.

The warning triangle with exclamation mark indicates important operating and maintenance instructions.

IMPORTANT INFORMATION

CAUTION! HIGH VOLUMES IN AUDIO PRODUCTS!

This equipment is designed for professional purposes and its commercial use must comply with the applicable national rules and regulations for accident prevention.

As the manufacturer of this product, Audibax has the responsibility to inform you about the potential health risks associated with its use. One such risk is hearing damage caused by prolonged exposure to high volume.

When this product is in use, it can generate high sound-pressure levels that may cause irreversible hearing damage to performers, employees, and audience members.

To prevent this, it is important to avoid exposing yourself or others to volumes exceeding 90 dB for an extended period of time.

PRODUCT DESCRIPTION

The class D digital power amplifier, featuring minimal power consumption and much higher efficiency up to 85%; In addition, it helps save space in the installation rack and generates less heat to extend its useful life as an amplifier. result.

Class D digital amplifiers have a rated output power of 240W/350W/500W (depending on version) per two channels, so they could be used as a two-zone multi-source public address system at minimal cost. Versatile 100V high-impedance and 8-ohm low-impedance speaker outputs let you tackle PA fixtures and high-fidelity stereo installation jobs.

There are two balanced inputs per Euroblock connector for each channel with gain control. Four separate zone speaker outputs, both 100V and 4-16 ohms. The built-in four-channel separate high-pass filters can be enabled or disabled via DIP switch presetting.

Automatic standby mode is enabled after detecting no input signal for one minute, activated when receiving signal on any input. Visual working status indicators include guard, clip, entry and exit for easy monitoring. With full protection against short circuit, overload, high temperature, clip and DC.

Wide AC power supply from 115V to 230V, thus supporting equipment installation anywhere in the world.

6. POWER SWITCH

Power switch used to power on and power off the equipment.

REAR PANEL

1. AC POWER Socket

AC power cord for 110V to 230V input, the supply voltage is automatically switched between 100V to 230V.

2. 100V SPEAKER OUTPUT

The 100V output mode is only and explicitly for high impedance speakers, avoid connecting low impedance speakers in this format. There are two independent 100V speaker outputs that can be managed respectively. The output of these speakers is supplied in a Euroblock connector.

Always connect the correct polarity between speaker and amplifier to avoid short circuits. Never connect low impedance speakers to the 100V format, it may cause it to break.

3. LINE INPUT

The line input accepts balanced or unbalanced inputs, these inputs are supplied on Euroblock connectors.

There are two independent line input channels that can be managed respectively.

4. 8Ω SPEAKER OUTPUT

The speaker outputs will be connected to low impedance speakers of 4/8/16 Ohms, pin 2 of the connector to the negative pole of the speaker and pin 3 of the connector to the positive pole of the speaker. There are two independent 8 Ω speaker outputs that can be managed respectively. The output of these speakers is supplied in a Euroblock connector. Never mix the negative and positive end, which may cause short circuit protection. Never connect your 100V line speaker to these 8 Ω ends as they can burn out the speaker or cause heavy distortion.

5. Volume control

Signal input level adjustment per channel.

6. HIGH PASS FILTER

The high pass filter function will be enabled or disabled by presetting the separate two-channel DIP switch. There are separate two-channel high-pass filters that can be managed respectively.

7. AUTOMATIC STANDBY

The auto standby function will be enabled or disabled by presetting the separate two-channel DIP switch. The auto standby feature enabled will automatically enter standby once no input has been detected within 2 minutes. The amplifier will activate immediately once the input signal is detected.

8. 100V and 70V line switch

Switch to toggle high impedance output between 70V or 100V

SPEAKER CONNECTION

Before connecting the speakers, disconnect the AC power cord. Please note the proper connection terminals as shown below. Make sure the total impedance is not less than the stated nominal impedance.

- Connection of speaker systems from 4 to 16 Ω

When connecting conventional 4 to 16 Ω speaker systems, connect the positive (+) side of the speaker to the terminal labeled 4 to 16 Ω. Connect the negative (-) side of the speaker to the terminal labeled COM (pin 2)

- Connecting high impedance distributed speaker systems

When connecting a high impedance (100V) speaker system in parallel, connect the positive (+) side of the speaker to the terminal labeled 100V (pin 3). Connect the negative (-) side of the speaker to the terminal labeled - (pin 1)
