Omnitronic LH-031 Headphone Amplifier

Powerful 4-Channel Headphone Amplifier for Professional Use!

The Omnitronic LH-031 headphone amplifier brings together four separately adjustable outputs to distribute a single input signal evenly and precisely to multiple headphones - ideal for installations, mobile setups, or DJs. With a stereo input via phono and 6.3 mm jack, switchable to mono, and outstanding signal quality with a frequency range of 20 - 20,000 Hz, the unit delivers convincing performance. Its compact, rugged housing and straightforward operation make it a reliable choice for your monitoring system.

Efficient Signal Distribution

With the LH-031 you can split a single audio signal (e.g., from a DJ mixer or audio interface) to four headphones/headphone outputs. Each output features its own volume control, allowing you to set individual levels for each listener. That keeps your monitoring clear and free of interference, even in demanding setups.

High-Quality Connections and Switching Options

The headphone amplifier offers a stereo input via phono as well as a 6.3 mm (1/4") jack - a 3.5 mm (1/8") jack can also be used. Operation can be switched from stereo to mono, which is handy in many installation and live scenarios. The four outputs are all 6.3 mm jack sockets. This versatility makes the unit flexible to use.

Top Technical Specs for Clean Monitoring

The unit impresses with a frequency range of 20 - 20,000 Hz and a signal-to-noise ratio of >90 dB as well as a total harmonic distortion of less than 0.008% at 1 kHz. Input impedance is 100 kO (unbalanced), output impedance 51 O - figures that speak to high-quality signal reproduction. Thanks to a power supply of 100–240 V AC and a compact housing, the LH-031 is also suitable for mobile use or tight installation situations.
