You Need The STA-1!
APPLICATION: The STA-1 is part of a group of products in the STICK-ON series, designed by Radio
Design Labs, the STA-1 contains two identical circuits. Each is both an electronic line transformer, and an
amplifier. The durable adhesives provided with the STA-1 permit permanent or removable mounting. The
STA-1 can be treated just like a pair of audio transformers with gain making it ideal for most any audio line
application requiring amplification and/or conversion between balanced or unbalanced operation! Some
features of the STA-1 are:
•
•

•
Up to 20 dB Gain In an Audio Line
Conversion from Balanced to Unbalanced
Conversion from Unbalanced to Balanced
Conversion from High to Low Impedance
Conversion from Low to High Impedance
To Bridge an Audio Line Feed
To Precisely Match Audio Levels
No capacitors or transformers in the audio circuits
Two identical amplifier circuits in each STA-1
True DC amplifiers provide impeccable audio quality
Ultra-low distortion
Ultra-low noise
18 dB of headroom at operating level
Output level adjustable from off to 20 dB gain
Provides -10 dBV unbalanced to +4 dBu balanced conversion
Multi-turn trimmers for precise level adjustment
Recessed adjustments discourage tampering
All inputs and outputs are RF bypassed
Full operation in either high or low impedance circuits
Operation unaffected by unbalancing of inputs or outputs
Outputs short-circuit protected
Very high common-mode rejection when bridging balanced lines
Positive connections via barrier block. No audio connectors to wire
