Product Description |
|||||||||||||||
| The STA2A is a dual channel, line level audio preamplifier. Each channel is identical. The audio inputs are bridged at 20 k and accept either an unbalanced or a balanced audio signal. Gain is adjustable from unity to 24 dB using a 25turn precision audio taper trimming potentiometer. The output line driver circuits are designed to drive long balanced audio lines into 600 loads. The STA2A features wide band circuitry for excellent phase response, low noise, low distortion and exceptional audio clarity. RDLs Supply Flex power input configuration is included in the STA2A. The power supply input may be fed from a floating not ground referenced 24 Vdc power source, from a bipolar power supply 12 Vdc or 15 Vdc or from a ground referenced 24 Vdc power supply. Many audio products provide optimum performance when feeding into a bridging input, but may not provide the output needed to directly drive low impedance lines terminated with 600 transformers. The STA2A is specifically designed for such installations, and is also ideal in installations requiring high gain in linelevel audio transmission. | |||||||||||||||
