Professional monitor headphone amplifier for microphones and music sources

This professional-grade monitor headphone amplifier is designed to meet the needs of both studio and live performance environments. It offers the flexibility to connect both a microphone and a stereo line-level music source, making it ideal for musicians, vocalists, and audio engineers who require precise monitoring.

Separate microphone and monitor controls

To ensure optimal sound control, the amplifier features independent level adjustments for both the microphone input and the stereo monitor input. This allows users to fine-tune their audio mix, making it easier to balance the microphone and music source effectively. The stereo input can also be switched to mono if desired, providing added versatility depending on the setup requirements.

Versatile headphone output options

The amplifier is equipped with two headphone output options: a ¼-inch (6.35mm) stereo jack and a 3.5mm stereo jack. This dual output design accommodates a wide range of headphones, from professional studio models to consumer-grade earbuds, ensuring compatibility and ease of use for any situation.

High-quality microphone input and signal pass-through

The microphone input is facilitated through a balanced XLR connector, known for its noise-reducing capabilities and superior audio quality. Additionally, it includes a through socket, allowing the microphone signal to be linked to other audio equipment without interruption. This feature is particularly useful in complex setups where the microphone signal needs to be routed to multiple devices.

Robust stereo line input

The line input is handled via a ¼-inch stereo jack, providing a reliable connection for various music sources such as mixers, audio interfaces, and playback devices. The clear and dynamic sound quality ensures that users can monitor their audio source with precision, making this amplifier an excellent choice for both recording studios and live venues.
