RDL EZ-PA20X 20W Stereo Amplifier / 10W per Channel 8 ohm / Selectable 4 ohm 8 ohm / Limiter

Description

The EZ-PA20X is a compact stereo audio amplifier designed to deliver reliable, low-profile amplification for commercial and institutional sound systems. It provides front-panel level control and an intuitive user interface for on-site adjustments. The unit is engineered to drive 4 ohm or 8 ohm loudspeakers and includes a worldwide-compatible power supply.

Key features include 10 watts RMS per channel into 8 ohm, selectable output impedance for 4 ohm operation, and an integral compressor/limiter that controls overloads without harsh clipping. The limiter reduces distortion by preventing clipping and produces an output level comparable to higher rated amplifiers. A rear-panel switch selects mono or stereo operation and allows summing of left and right inputs when required.

Performance specifications show a frequency response of 35 Hz to 20 kHz at 10 watts, total harmonic distortion plus noise under 0.25 percent, and crosstalk better than -68 dB at 1 kHz. Noise floor is specified at below -70 dB when operating below 10 watts. Gain is adjustable from off to 32 dB to match a range of line-level sources.

Connectivity is straightforward with an unbalanced RCA line input and discrete left and right outputs for each channel. The rear-panel impedance select switch permits matching to common speaker loads. Mono mode sums the left and right inputs to a single mono output when center-fill or summed coverage is required.

The EZ-PA20X is suitable for houses of worship, restaurants, clubs, meeting rooms, classrooms, conference rooms and other commercial installations requiring modest continuous power and reliable dynamics control. Its integrated limiter and compact footprint make it practical where cabinet or rack space is limited. The amplifier’s sound character and limiter behavior provide useful headroom in environments with variable program material.

Installation is simple using the unit’s 1/3 rack width form factor and standard connector layout. The front-panel level control offers immediate local adjustment while the robust case supports repeated handling. Build quality and thermal behavior are appropriate for continuous commercial use when operated within the specified limits.
