Long Description

The Voltech 1800 Max is a custom-built 2.2CH high-power Class-D audio amplifier designed for users who want powerful stereo sound combined with serious dual-subwoofer bass performance.

Instead of using a single amplifier module for the entire system, the Voltech 1800 Max uses a dedicated amplifier architecture:

• 1 × WUZHI Audio ZK-3002 / TPA3255 for stereo channels
• 2 × WUZHI Audio ZK-6001 / TPA3255 for subwoofer channels
• WUZHI Audio ZK-PRO2 for Bluetooth and audio control
• 48V 20A SMPS for high-power DC supply

This configuration creates a dedicated 2.2-channel system, with separate amplification for the left/right stereo speakers and two subwoofer channels.

The result is a powerful custom audio platform suitable for home entertainment, parties, custom speaker systems, bass-heavy music, and high-output DIY audio projects.

Powerful 2.2 Channel Architecture

The Voltech 1800 Max is built around a dedicated 2.2CH amplification configuration.

Stereo Section

The stereo section uses:

WUZHI Audio ZK-3002 – TPA3255 Class-D

The stereo amplifier is designed to power compatible 6–10 inch speakers.

Depending on the speaker impedance and wiring configuration, the system can be used with:

• 2 stereo speakers
• 4 speakers in an appropriate configuration

The stereo section is designed to provide clean vocals, detailed mids, strong mid-bass, and powerful stereo output.

Dual Subwoofer Amplification

For bass reproduction, the Voltech 1800 Max uses:

2 × WUZHI Audio ZK-6001 – TPA3255

Configured subwoofer output:

600W + 600W

This provides two dedicated subwoofer amplifier channels for a powerful dual-subwoofer setup.

Compatible subwoofer configurations can include:

• 2 × 8-inch subwoofers
• 2 × 10-inch subwoofers
• 2 × 12-inch subwoofers
• 2 × 15-inch subwoofers
• Multiple subwoofer drivers when correctly wired

Subwoofer impedance and wiring must remain within the supported operating range of the amplifier modules.

WUZHI Audio ZK-PRO2 Bluetooth Controller

along with the integrated audio spectrum display.

Rear Panel

The rear section uses:

Acrylic Sheet

This combination of metal construction, Alcobon finishing, and acrylic detailing gives the amplifier a distinctive custom-built appearance.

48V 20A High-Power SMPS

The amplifier is powered by a high-power:

48V DC / 20A SMPS

Power Supply Specifications

• AC Input: 220V AC
• DC Output: 48V
• Maximum Current: 20A
• Maximum Rated Supply Capacity: 960W

The SMPS is designed to provide a stable high-power DC supply for the TPA3255-based amplifier system.

Actual continuous audio output depends on the power supply, speaker impedance, amplifier efficiency, thermal conditions, and distortion level.

Recommended Stereo Speakers

The Voltech 1800 Max is suitable for compatible:

6–10 inch stereo speakers

Possible configurations:

• 2 × stereo speakers
• 4 × speakers in a suitable wiring configuration

For best results, use speakers with appropriate impedance and power handling.

Recommended subwoofer size:

8–15 inches

Possible configurations include:

• Dual 8-inch
• Dual 10-inch
• Dual 12-inch
• Dual 15-inch
• Multiple drivers with correct wiring

Recommended impedance:

2–4Ω, depending on the specific amplifier channel and wiring configuration.

Always verify the final speaker impedance before connecting the system.

Sound Performance

The Voltech 1800 Max is designed for:

• Deep and powerful bass
• Strong subwoofer output
• Clear vocals
• Detailed midrange
• Powerful stereo playback
• High dynamic range

Important Notes

• The 1800W PMPO figure represents the claimed maximum/marketing power specification and should not be interpreted as continuous RMS output.
• Actual output depends on speaker impedance, power supply capability, amplifier efficiency, cooling, distortion level, and operating conditions.
• The approximately 1000W RMS figure is a system configuration estimate, not a guaranteed continuous output under every operating condition.
• Use speakers and subwoofers with suitable RMS power ratings.
• Correct speaker impedance and wiring must be maintained.
• Do not connect speaker outputs together unless the specific amplifier configuration explicitly supports it.
• Adequate ventilation is recommended during high-power operation.
• Do not short-circuit the speaker outputs.
• The amplifier's internal SMPS operates from 220V AC and produces 48V DC.
