The 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 either high or low impedance, balanced or ...

The ST-MX3 is part of a group of products in the STICK-ON series from Radio Design Labs. The durable bottom adhesive permits quick, permanent mounting nearly anywhere, or use it with RDL's racking accessories. The ST-MX3 gives you the ...

The STA-1 is a dual-channel line amplifier with bridging inputs, adjustable gain or loss, and low impedance outputs. Each of the two identical circuits are both an electronic line transformer and a line amplifier. Hook up the STA-1 just ...

The 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 off to +65 dB, two balanced or unbalanced outputs, and available ...

The STM-3 is part of the group of "STICK-ON" products from Radio Design Labs. The STM-3 is a quality microphone preamplifier designed for use in commercial sound, broadcast, and recording applications. Its compact size makes it ideally ...

The STM-DA3 is designed for use in quality commercial sound, broadcast and recording applications. The 1.2 kOhm balanced input accepts a wide variety of microphone input levels without loading professional low impedance microphones. A ...

The STA-2A is a dual-channel, line-level audio preamplifier. Each channel is identical. The audio inputs are bridged at 20 kW and accept either an unbalanced or a balanced audio signal. Gain is adjustable from unity gain to +24 dB using a ...

The ST-MPA2 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. ...

The STM-2X is the ideal choice in many installations where a microphone preamplifier is required, and is the ideal choice where either a toggle-type switch or push-to-talk switch is to be provided for microphone control, particularly if ...

The STA-1M allows bridging any audio line, adjusting the gain, and driving a balanced or unbalanced line. The circuit design allows the input to accept either balanced or unbalanced signals, of either high or low impedance. This is an ...
