Commercial Sound Equipment

The RDL STP-1 is a pair of convenient attenuator pads that can be located at the precise location that attenuation is needed.

The TX-8A is the ideal choice in many applications requiring superior quality transformer coupling between the output of a 4 or 8 Ohm power amplifier and the input of an audio mixer or amplifier. A front-panel LEVEL control allows the output to be adjusted for -10 dBV or +4 dBu over a wide range of amplified power levels.

The RDL ST-PA2 features a single, unbalanced audio input, a gain control, and two outputs. The first output is designed to deliver a clean 2 watts RMS into an 8 Ω speaker.

The DB-CIJ3 is the ideal choice in installations requiring the passive mixing of two unbalanced line-level audio sources to feed a mono balanced (or unbalanced) audio line.

The ST-MPA24 contains two identical phantom power circuits and a common power supply input. If only one mic input is to be converted for phantom operation, only one circuit needs to be used. Each circuit has a mic input and a mic output. Phantom voltage appears on each of the mic input terminals. There is no voltage on the mic output terminals. Therefore, the ST-MPA24 can convert any existing mic input into a phantom powered input.

The RDL ST-PA6 represents the second generation of RDLs® breakthrough in the traditional power vs. size ratio. Present technology permits features and performance at the most economical cost ever. The ST-PA6 offers 6 Watts of power for a price you would expect to pay for 3 Watts.

The RDL ST-RX2 has a single line‑level audio input and two line‑level audio outputs and is part of a group of products in the STICK-ON series from Radio Design Labs. The durable bottom adhesive permits quick, permanent or removable mounting nearly anywhere or it may be used with RDL racking accessories.

The RDL STM-1 is a low-cost quality microphone preamplifier designed for use in commercial sound and broadcast applications. The compact size makes it ideal where a larger or heavier preamp cannot be used.

The RDL STA-1M allows bridging any audio line, adjusting the gain, and driving a balanced or unbalanced line.

The RDL ST-PA18 features a balanced line level input that may be connected unbalanced. The gain control range will accommodate standard unbalanced levels as well as professional balanced levels.

The RDL ST-MX3 is a line-level mixer module in the STICK-ON Series of products. It provides audio mixing of three line-level inputs with individual input gain adjustments.

The ST‑NG1 is the ideal choice where random white or pink noise is needed. It is suitable either as a reference noise source for audio measurements or as a masking noise source in engineered sound or counter‑intelligence applications.

The ST-UMX3 is a three-channel audio mixer for combining mic-level or line-level signals to a single output.

The RDL STM-DA3 is designed for use in quality commercial sound, broadcast and recording applications and accepts a wide variety of microphone input levels without loading professional low impedance microphones.

The RDL ST-DA3 gives you the advantages of an audio distribution amplifier PLUS you can put it where you need it. The ST-DA3 allows bridging of any audio line, adjusting the gain, and driving up to three high or low impedance, balanced or unbalanced loads.

The RDL FP-PA20B produces average audio levels and audio clarity normally expected of amplifiers delivering much higher output power.

The RDL STM-2 is a quality low-noise microphone preamplifier designed for use in commercial sound, broadcast, and recording. The STM-2 is very flexible, with gain adjustment from 35 to 65 dB, two balanced or unbalanced outputs, and available phantom supply input.

The RDL D-RC type remote audio mixing controls provide user-accessible volume knobs for two or three sources. Each control is available with level controls only, or with level controls plus a muting button for each channel.

The RDL FP-PA20 produces average audio levels and audio clarity normally expected of amplifiers delivering much higher output power.
