You Need The STA-1M!
APPLICATION: The STA-1M is part of a group of products in the STICK-ON series from Radio Design
Labs. The durable adhesives provided with the STA-1M permit permanent or removable mounting. The
STA-1M gives you the advantages of balanced/unbalanced configuration conversion, impedance
conversion, level boost or cut, with a big plus... you can put it where you need it!
The STA-1M allows bridging of 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 instrumentation type input stage that will amplify the differential input,
regardless of ground reference. This offers increased possibilities for eliminating ground loops in audio
systems.
The output is capable of driving into either high or low impedance loads.
And the output may be
connected either balanced or unbalanced. The STA-1M features superior circuitry that produces the
unsurpassed pure clarity for which RDL products are known! Some features are:
Functions as an electronic transformer with isolation and gain (or loss).
Impeccable audio quality.
Ultra-low distortion
Ultra-low noise.
Output level adjustable for all ranges of conversion between – 10 dBV and +4 dBu signals.
Ample headroom at operating level.
Full operation in either high or low impedance circuits.
Outputs short-circuit protected.
Positive connections via barrier block - no audio connectors to wire.
Whether you need to simply boost a line level, convert between balanced and unbalanced lines or convert
between high and low impedances, the STA-1M is today’ s simple, no-compromise, cost-effective solution!

Use the STA-1M combined with other RDL RACK-UP
, STICK-ON, TX™, or FLAT-PAK™ series products
as part of a complete audio/video system.
