RDL EZ-MXA20X 20W Stereo Mixer-Amplifier / 10W per ch into 8 Ohm / XLR Mic / RCA Line / EQ / Limiter / 24V

Description

The EZ-MXA20X is a compact stereo mixer-amplifier designed to combine a microphone preamplifier, line-level inputs and a power amplifier in a 1/3 rack chassis. It delivers rated output power of 10 Watts RMS per channel into 8 Ohm and 8 Watts RMS per channel into 4 Ohm. The unit provides straightforward front-panel controls and a small footprint for tight installations.

The unit includes a balanced XLR mic input with switch-selectable 24 V phantom and two unbalanced RCA line inputs. Bass and treble tone controls allow basic tonal shaping while an integral overload compressor/limiter with LED indicator controls peaks and reduces clipping. A rear-panel switch selects load impedance to match 4 Ohm or 8 Ohm speakers.

Performance specifications include frequency response from 50 Hz to 20 kHz for mic input and 35 Hz to 20 kHz for line input at rated power, THD+N under 0.25 percent and crosstalk below -68 dB at 1 kHz. Mic gain is adjustable up to 74 dB while line gain reaches up to 32 dB. Noise and CMRR specifications make the unit suitable for spoken-word and background-music applications.

Connectivity is provided via a balanced XLR mic jack and stereo RCA line jacks on the rear panel, plus left and right speaker outputs with switch-selectable impedance. The module is powered by an external 24 Vdc supply and the supply current measures 170 mA at idle and up to 1000 mA peak. The limiter and LED indicator give visual feedback and protect downstream loudspeakers from overload.

Typical applications include houses of worship, restaurants, clubs, meeting rooms and other commercial sound systems that require integrated mic mixing and modest local amplification. The EZ-MXA20X suits speech reinforcement, background music and small-venue paging duties. Its limiter allows perceived output comparable to higher-power amplifiers while limiting clipping.

Installation is quick thanks to the compact 1/3 rack width form factor and simple control layout. The metal chassis and straightforward connectors support long-term reliability in installed environments. Overall the EZ-MXA20X offers a compact mixer-amplifier solution with tone control, phantom power and an effective limiter for stable operation.
