LAYVIKAY Professional Power Amplifier

Product Information

This series of power amplifiers features a special circuit design that prioritizes product stability under long-term continuous use at full power. The PCB board utilizes double-sided wiring through-hole technology to minimize false welding of internal components during transportation and protect against damage caused by overcurrent when operating at full power for extended periods.

The amplifier’s circuit layout, designed using computer simulation systems, allows for an SNR (signal-to-oise ratio) of over 110dB, meeting the requirements for touring sound applications. It offers high efficiency with high power output and a damping factor of 400 or more, resulting in strong and elastic sound quality.

Product Usage Instructions

IMPORTANT SAFETY INSTRUCTIONS

Read these instructions.
Keep these instructions.
Heed all warnings.
Follow all instructions.
Do not use this apparatus near water.
Clean only with a dry cloth.
Do not block any ventilation openings.
Do not install near any heat sources such as radiators, heat registers, or stoves.
Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades one wider than the other. A grounding-type plug has two blades and a third grounding prong. The wide blade or the third prong is provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for the replacement of the obsolete outlet.

WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPARATUS TO RAIN OR MOISTURE.

Instructions on Safe Operations

Installation

Ensure the power amplifier is placed in a well-ventilated location.
Avoid installing near water or heat sources.

Operation

Connect the power amplifier to a suitable power source.
Ensure the power is turned off before making any connections.
Connect the XLR-type cables to the appropriate sockets as follows:
- Pin 1: Ground
- Pin 2: Hot (+)
- Pin 3: Cold (-)
Avoid short-circuiting or overloading the amplifier’s output to ensure long-term normal operation.

This series of power amplifiers features

This series adopts a special circuit design, focusing on product stability under conditions of long-term continuous use at full power. The PCB board uses double-sided wiring through-hole technology, which can reduce false welding of internal components during transportation and overcurrent to damage products by working on full power for a long time the circuit layout designed by the computer simulation system can allows the amplifier have over 110dB SNR, to meet the requirement on touring sound applications, it has high efficiency with high power type. The damping factor of This series of products can be up to 400 or more, the sound is strong and elastic. High powerful, extremely strong driving ability. Adopt an optimized cooling system and high-quality cooling fan to ensure stability for a long-time working at high power. The fan can speed up automatically by variations of temperature in the machine, (when connected with the load impedance is too low or the temperature is too high, the machine will automatically adjust the power supply to reduce the internal resistance. This function is only used on 5 + or above.), can improve the sound quality and protect the machine effectively, and highly improved reliability. Low distortion, high slew rate, more perfect sound quality, and higher resolution. Dual-channel can be bridged and connected. The fan can speed up automatically by variations of temperature in the machine. Start-up delay, overload, short circuit, overtemperature, load short-circuit protection. Limiting control. Independent input control.

Instructions on Safe Operations

Install:

The device can only be inserted in the AC power supply socket of the specification or the specification of the specification on the instructions of the user manual.

Otherwise, it may cause a fire or an electric shock.

Pls don’t scratch, bend, twist, pull, or heat the power cord, or may damage the power cord, and lead to fire or electric shock.
Pls don’t open the device cover or may result in an electric shock. If you think there needs any internal inspection, maintenance, or repair, please contact your dealer.
The device has a ventilation hole on the front and back, to avoid the internal temperature rising too high. Do not block the ventilation holes.

Blocked ventilation holes may cause a fire.

Operation:

When connecting the device, pls turn off all musical instruments, audio equipment, and speakers, pls use the correct cable, and connect the device as per instructions.
For the supply voltage, please see the label on the back of the machine.

Connecting the needle socket Division:

XLR type connecting socket should be wired as follows.
