MDR1248 specifications

The Samson MDR1248 is a versatile and robust mixer designed for audio professionals and enthusiasts looking for high-quality sound in a compact format. Engineered for both live sound and studio applications, the MDR1248 delivers a comprehensive set of features that make it suitable for various scenarios, including band rehearsals, live performances, and recording sessions.

At the heart of the MDR1248 are 12 microphone inputs, each equipped with high-quality preamps. These preamps ensure a clean, transparent sound, providing ample headroom for capturing vocals and instruments with clarity. The mixer also includes four stereo line inputs, making it easy to connect synthesizers, drum machines, or other audio devices. The combination of microphone and line inputs allows for a flexible mixing setup, accommodating a wide range of audio sources.

One notable feature of the MDR1248 is its built-in 48V phantom power. This functionality is essential for powering condenser microphones, providing the necessary voltage to ensure high-quality sound capture. Additionally, the mixer offers a comprehensive EQ section, with three-band equalization on each channel, allowing users to tailor the sound to their liking. This feature is particularly useful for live sound applications where the acoustic environment can vary significantly.

The MDR1248 also incorporates advanced signal processing capabilities, including built-in digital effects. With a variety of reverb, delay, and modulation effects, users can enhance their audio signals in real-time, adding creativity and depth to their performances. This functionality is complemented by an intuitive interface that makes it easy to navigate and adjust settings quickly.

Moreover, the mixer features outputs for both main and auxiliary mixes, enabling users to create separate monitor mixes for performers on stage. The auxiliary sends can be used to route audio to external effects processors or monitors, offering further flexibility in audio management.

Portability is another hallmark of the MDR1248. Its rugged design ensures durability, making it ideal for mobile setups. The mixer also features a compact footprint, which is perfect for smaller venues or studios where space is a premium.

In summary, the Samson MDR1248 is a powerful and adaptable mixer that brings together high-quality audio performance, ease of use, and advanced features. Whether for a live event or studio recording, the MDR1248 is designed to meet the demands of audio professionals seeking reliability and versatility in a single package. This makes it an excellent choice for those looking to elevate their sound experience.
