You Need The ST-DA3!
The ST-DA3 is part of the group of versatile STICK-ON products from Radio Design Labs, featuring the
advanced circuitry for which RDL products are known. The durable adhesives provided with the ST-DA3
permit permanent or detachable mounting. Numerous mounting accessories, brackets and rack-mount
chassis are optionally available to facilitate any system design.
APPLICATION: The ST-DA3 allows the bridging of any audio line, adjustment of the gain, and driving up
to three outputs. Each output is driven by a separate amplifier, and is isolated from both the input and
from the other outputs. The circuit design allows the input to accept either balanced or unbalanced
signals, of either high or low impedance; and each output may be connected either balanced or
unbalanced. The ST-DA3 features wideband circuitry that produces the unsurpassed pure clarity for
which RDL products are known. Some features are:
•
Functions as an electronic transformer
•
Provides isolation, gain, and three outputs
•
Wideband amplifiers produce impeccable audio
•
Operates from ground-referenced, floating or bipolar power supply
•
Ultra-low distortion
•
Ultra-low noise
•
Excellent phase response
•
Gain adjustment 17 dB above or below unity
•
Ample headroom at operating level
•
Recessed multi-turn audio taper gain trimmer for precise control
•
Input and outputs are RF protected
•
Full operation in either high or low impedance circuits
•
Outputs are short circuit protected
•
Positive connections via barrier block
Wherever an audio distribution amplifier is needed, the ST-DA3 is the ideal choice. Use the ST-DA3
combined with other RDL RACK-UP
of a complete audio/video system.
