Mixer Omnitronic EM-260 6 channels

The Omnitronic EM-260 6 channels is a compact rackmount mixer designed to mix up to six inputs into a single stereo output. It combines three switchable mono mic/line inputs (balanced XLR) with three stereo line inputs (RCA), provides FX send/return and dedicated clip LEDs for microphone channels, and includes a stereo master output with a two-band EQ. The unit supports optional 12 V phantom power on each microphone input and offers separate stereo record outputs. Its dimensions and low weight make it suitable for portable and rack-mounted applications.

Advantages

The mixer offers flexible input options with three balanced XLR microphone channels that can be switched to line level and three dedicated RCA stereo line channels, allowing simultaneous connection of microphones and playback devices. Each mic channel features clip indication and optional 12 V phantom power. FX send/return with level control and a stereo master output with a two-band equalizer provide basic routing and tone-shaping capabilities in a 1U rack format. Low total harmonic distortion (0.025%) and a 69 dB line signal-to-noise ratio contribute to clear audio performance.

How to use

Connect microphones to the XLR inputs or line sources to the RCA inputs and set each mic input to the appropriate mic/line mode. Use the individual channel controls to adjust gain and routing, monitor the clip LEDs to avoid overload, and enable 12 V phantom power only when required by condenser microphones. Send effects via the FX send and return, adjust the FX level control to blend processed signal, and set the stereo master level and two-band EQ to achieve the desired overall tonal balance. Use the record outputs to feed a recorder or external device.

Recommendations

For best results, avoid pushing channel gains into the clip range; use the clip LEDs as a guide. Enable phantom power only for microphones that require it, and connect balanced cables for mic inputs when possible to minimize noise. Place the unit in a ventilated rack space and keep signal levels moderate to preserve the specified S/N ratio and low distortion.
