Recommended Accessories

Radio Design Labs' RU-PA518 is part of the group of versatile RACK-UP products, featuring the advanced circuitry for which RDL products are known, combined with accessible, user-friendly controls and displays. The ultra-compact design permits high-density installations, with 3 products mounted in a single rack unit! The RU-PA518 may be placed on a shelf or mounted below a shelf using optional mounting brackets. Optional rack-mount adapters (RU-RA3) are available for conventional RACK-UP series installation.

The RU-PA518 is a very versatile audio amplifier ideally suited to a wide variety of installations. This amplifier features two modes of operation: stereo and bridged mono. Each mode is switch selectable on the rear panel.

NOTE: Radio Design Labs' PS-24V2A power supply is NOT included but is required in order to power this product.  Please see the "Accessories" tab or click here for more information on the PS-24V2A power supply.

In stereo mode, each of the two inputs feed its respective left or right output. Front-panel level controls set the gain for left (channel A) and right (channel B). When the rear-panel switch is set to the bridge mode, the two inputs (A and B) are mixed together and fed to the output.

In either the stereo or mono modes, an internal audio peak limiter may be turned on using a rear-panel switch. The limiter protects the speakers from high transient audio peaks which permits more of the amplifier’s power to be delivered to the speakers without clipping. This allows the RU-PA518 to deliver more unclipped power than is possible in a typical power amplifier of similar power rating. A front-panel LED flashes when the peak limiter operates, permitting accurate audio gain setting when operating at high levels.

In stereo mode, the RU-PA518 can be connected to either an 8 W or 4 W load, delivering more than 5 W RMS at 8 W or more than 9 W RMS into 4 W. In the bridge mono mode, the amplifier can deliver more than 18 W RMS into 8 W.

Each of the audio inputs is provided with both balanced and unbalanced connections. Balanced audio is connected through a rear-panel full-size barrier block. Unbalanced audio is connected through a standard phono input jack. Outputs are available on a barrier block. 24 Vdc power is connected through either barrier block terminals or through a dc power jack mounted on the rear panel. Front-panel controls include two audio level knobs and a power switch with an LED indicator.
