Congratulations on your purchase of a Seta phonograph preamplifier!
The new, ground-breaking
Seta Nano is an ultra low noise, fully balanced design also featuring an ultra wide frequency bandwidth of
DC to 3 MHz (-3 dB). This provides you with the key to obtaining stunning, three-dimensional music
reproduction from your phonograph records.
The Seta is designed to be used as a front-end preamplifier for connecting to high resolution (192 kHz /
24 bit), balanced - input computer audio interfaces. In conjunction with Channel D
Pure Vinyl
software,
used for applying the RIAA phono correction curve, the strengths of the latest, 21st century cutting-edge
analog and digital technologies are brought together, delivering superb, high definition, transparent vinyl
playback.
For those audiophiles insisting on an all-analog signal path, the RCA output connectors of the Seta Nano
provide a conventional, RIAA-corrected output signal. The Flat and RIAA outputs may be used
simultaneously (another, unique feature, unprecedented for a phonograph preamplifier), to support the
best of the Analog and Digital worlds.
Getting Started
Please take the time to carefully read this Installation and Use Guide, to familiarize yourself with the
installation and operation of the Seta.
Important:
If the package you received from your shipper is below room temperature, please allow the
sealed inner carton containing the product to acclimate at room temperature for a few hours before
opening it, to avoid causing condensation on cold internal surfaces.
The following items are included. Please check the package and notify Channel D of any shortage:

Signal connections should be made to the Seta Nano only while the power supply is disconnected. A
Low Output type cartridge (less than 0.9 mV) having an internal resistance of 50 ohms or less must
be connected for proper operation.
(1, 2) Signal Inputs
(1)
The RCA inputs may be used with conventional shielded cable (single-ended) phono connections.
They also serve as single-ended to balanced adapters (provided that the turntable ground connection is
isolated). Consult the section of this Installation Guide concerning the proper configuration of the internal
single ended / balanced jumpers.
The factory setting is with the jumpers set for balanced operation.
(2)
XLR inputs are intended for use with balanced (shielded twisted pair) turntable connections. For
optimum, low noise operation this is the preferred type of connection. Balanced wiring provides better
noise immunity than conventional shielded (single conductor plus shield) cable.
(3, 4) Signal Outputs
(3)
The balanced XLR outputs provide a signal without RIAA correction (“Flat”), and are intended to be
connected to the
balanced
inputs of a high quality audio interface (ADC), for use with Channel D’s Pure
Vinyl software (for Macintosh computers) for applying RIAA compensation (or other similar software on
other computer platforms). (Consult the Pure Vinyl software User Guide for more information.)
