RDL STA-1 Stick-On Electronic Transformer/Line AmplifierThe STA 1 is a dual channel line level preamplifier with bridging inputs, adjustable gain or loss, and low impedance outputs. Each of the two identical circuits is both an electronic line transformer and a line amplifier. Hook up the STA 1 just like a pair of audio transformers with gain. True dc amplifiers produce unsurpassed audio clarity, high common mode rejection, ultra low distortion and low noise. The STA 1 is perfect for most line

both when connected as an audio interface and when used in Stand-Alone operation

especially below 500Hz

and packaging designs

the maximum number of simultaneous input and output can be increased to 32 channels – even at 96kHz/24-bit resolution

The electro-optical detector

Can also be used as a transmitting device

Over-current and Thermal Protection Circuitry prevents potential damage from overloads

Typical applications will find either or both of the Model 5121's analog or digital audio inputs being interfaced with outputs provided by fiber-optic transport modules

based on the X Series (XLR worldwide accepted standard)Rugged diecast shell for best reliability

This is typically used for on-air broadcast applications

it is possible to switch input sources for a channel without interrupting to the sound
