## Long description

The Edifier MR4 wired loudspeaker delivers a compact and powerful design that upgrades listening for small studio and desktop environments. It provides professional sound performance with a 2.0-channel configuration and 21 W RMS power, a frequency response suited for monitoring tasks, and a classic black MDF cabinet intended to reduce acoustic resonance for a more accurate tonal presentation.
Advantages
The speaker combines a 1-inch silk-dome tweeter with a special coating for smooth, refined high frequencies and a 4-inch MICA-reinforced woofer for deeper, more precise bass. Multiple input options—including balanced TRS, unbalanced RCA and Aux—and a dedicated headphone output make the MR4 flexible for connection to audio interfaces, mixers, computers and mobile devices. A multifunction knob controls volume, power and sound-effect mode to simplify operation.
Suitable for
Home and project studios for monitoring and mixing
Desktop audio for content creators and multimedia playback
Connection to audio interfaces, mixers, computers and mobile devices

How to use
Place the MR4 speakers on stands or at ear level on a desktop with adequate distance from walls to reduce low-frequency build-up. Connect the balanced TRS to an audio interface or mixer for best noise performance, or use RCA/Aux for consumer devices. Use the front knob to set listening level, long press to power on/off and short press to switch the sound-effect mode.
Usage recommendations
For accurate monitoring, allow the speakers to warm up for a few minutes before critical listening, position them in an equilateral triangle with the listening position, and avoid placing them directly against reflective surfaces. Use the balanced TRS input when available for lower interference and cleaner signal transfer.
