Omnitronic LH-045

The Omnitronic LH-045 is a compact tabletop microphone preamplifier designed for professional audio applications. This device offers high-quality signal processing with balanced XLR inputs and outputs for clean audio amplification of various microphone types. The preamplifier features an adjustable gain control ranging from 20 dB to 60 dB for precise level adjustment in different recording situations. Constructed with a durable metal housing measuring 120 mm in width, 80 mm in depth, and 45 mm in height, the unit weighs approximately 450 g for stable tabletop operation. The LH-045 includes 48 V phantom power for condenser microphones, with a frequency response of 20 Hz to 20 kHz and a signal-to-noise ratio better than 110 dB. Front panel controls include gain knobs, a phantom power switch, and a polarity reverse function, while rear panel connections provide XLR input and output interfaces. The operating temperature range is from 0 °C to 40 °C with a power consumption of under 5 W. The preamplifier utilizes professional components such as low-noise operational amplifiers and precision resistors for minimal distortion and reliable performance in studio, broadcast, and live sound environments. The unit requires an external DC power supply of 12 V, 500 mA (not included). It is suitable for voice recordings, instrument amplification, and voice reinforcement applications where clean signal amplification is essential.
