RDL STA-2A Stick-on Dual High Gain Line Amplifier w/ power supply
The STA-2A is a dual-channel, line-level audio preamplifier. Each channel is identical. The audio inputs are bridged at 20 kand accept either an unbalanced or a balanced audio signal. Gain is adjustable from unity to +24 dB using a 25-turn precision audio taper trimming potentiometer. The output line driver circuits are designed to drive long balanced audio lines into 600 loads.
The STA-2A features wideband circuitry for excellent phase response, low noise, low distortion and exceptional audio clarity. RDL's SupplyFlex power input configuration is included in the STA-2A. 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 STA-2A is specifically designed for such installations, and is also ideal in installations requiring high gain in line-level audio transmission.
Features:
Up to 24 dB Gain in Audio Lines
Conversion between Unbalanced and Balanced
Conversion between High and Low Impedance
Low-Impedance, High-Current Line Drivers
Dual-Channel Line-Level Preamplifiers

Clearly there is a gray area between 3 and 4.
It is not fair to the buyer or seller to say for parts or not working when it is just "untested".
On these listings, our company's condition "used" does NOT necessarily mean "fully operational and functions as intended". If fact it may have unknown flaws and deficiencies. the item has only been tested to the extent described in the testing notes. Additional testing may be performed upon request of the buyer before shipment to ensure a satisfactory transaction for both parties.
