Product information

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

Key specifications

Power: 21 W RMS (total, 2.0 channels)
Drivers: 1-inch silk dome tweeter; 4-inch MICA-reinforced woofer
Frequency range: 60–20,000 Hz
Cabinet material: MDF wood
Connectivity: wired with balanced 1/4-inch TRS, RCA unbalanced, Aux input, and headphone output
Colour: black

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.

Bluetooth: Bluetooth is a low-power radio technology developed to replace the cables and wires currently used to link or connect electronic devices such as personal computers, printers, and a wide variety of handheld devices including mobile phones. Because it uses radio-wave connectivity, a Bluetooth-enabled device has a constant, established connection to whatever browser it uses. This saves the user the trouble of logging on to check for emails or news updates, for example.: No
Connectivity technology: The technology that enables connectivity of the device, e.g. wired or wireless.: Wired
RMS rated power: RMS (Root mean square) is a measure of the continuous power required by a device, in particular audio amplifiers and loudspeakers.: 21 W
Recommended usage: What the product should be used for, and how it should be used (e.g. ambient temperature).: Studio
Audio output channels: An audio output channel is an electric circuit which acts as a path for a signal produced by a device. A device may have several audio output channels.: 2.0
Number of drivers: The quantity of drivers, which are individual transducers that converts electrical energy to sound waves.: 2
Product colour: The colour e.g. red, blue, green, black, white.: Black

Amplifier

Signal-to-Noise Ratio (SNR): This is the ratio of signal intensity to noise intensity.: 85 dB
Total Harmonic Distortion (THD): Total harmonic distortion is a measure of non-linear harmonic distortion and is given in %. Non-linear harmonic distortions are signals which were not present in the original before the signal was converted by the headphones. These unwanted signals are caused by the diaphragm, whose movements do not precisely move in time with the electric signals that cause it to move. Unfortunately, this is a feature of all electroacoustic transducers. Although it cannot be completely eliminated, suitable steps can be taken to minimise it. However, the user is not interested in why this distortion takes place but in how great the level of distortion must be for it to become perceptible. According to the findings of several research projects, a total harmonic distortion of 1% in the frequency range of 100 to 2000 Hz is imperceptible. Below 100 Hz, the perceptibility threshold lies at 10%.: 0.2 %
