Vivolink VL120004 Ενισχυτής ήχου 2.0 καναλιών Σπίτι Μαύρο

VL120004 is a compact Class-D digital amplifier from VivoLink with two line inputs and one microphone input, offering EQ control and microphone mixing. The unit provides a default stereo output of 2x20W at 4 Ω and can be bridged to deliver a mono output of 1x40W at 8 Ω. The amplifier accepts AC mains from 110–220 V and features 3.5 mm connectivity for speakers and headphones, making it suitable for small home audio setups.

Advantages

The Vivolink VL120004 delivers efficient Class-D amplification with low total harmonic distortion (THD ≈ 1%), compact dimensions (96 × 87 × 38 mm) for easy placement, and flexible input options including two line inputs and one MIC input with EQ and MIC mixing. It supports both stereo and bridged mono output modes, and can be controlled by front-panel buttons or via RS232 (IR control available with IR-VL120004 accessory).

Suitable for

• Small home audio systems
• Desktop speaker setups
• Microphone-enabled announcements or voice mixing in a room
• Applications requiring compact, low-power amplification

How to use

Connect source devices to the line inputs and a microphone to the MIC input using the appropriate 3.5 mm connectors. Set the desired EQ and mix microphone level using the unit’s controls. For stereo operation, connect two speakers to the left and right outputs at 4 Ω each. To obtain a single higher-power output, reconfigure the speaker wiring to the bridged mode for 1 × 40 W at 8 Ω following the manufacturer’s bridging instructions. Power the amplifier from an AC 110–220 V supply and use the front-panel buttons or RS232 connection for remote control; add the IR-VL120004 accessory if IR control is required.

Recommendations

Use speakers with impedance matching the selected output mode (4 Ω per channel in stereo, 8 Ω when bridged) and avoid continuous operation at maximum volume to maintain low distortion and long device life. Ensure proper ventilation around the compact enclosure during use.
