(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. -

Power Indicator Illuminates when external power is applied and the internal battery is operating normally. TRIM Control The TRIM control is a unique, precision trim control feature used for adjusting the cartridge inter-channel balance. All phono cartridges have some degree of channel imbalance, and this feature allows correction at the source, by making a fine adjustment to the preamplifier input gain. -
Page 6: Internal Switch And Jumper Configuration
The low impedance, balanced FLAT XLR outputs are intended for connection to the balanced inputs of a professional 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). -

Page 9: Boost Gain Setting
“BOOST 1” Gain Setting An additional gain of 6 dB can be realized by removing all four jumpers indicated in the illustration below. The jumpers can be removed entirely or placed in a “parking” position. To minimize noise pickup, “park” the jumpers on the pin which is farthest from the center of the board, for each pair of pins. The factory setting is with the jumpers bridged. -
Page 10: Cartridge Loading
If you’re accustomed to using conventional phonograph preamplifiers, the available Seta gain settings may seem somewhat lower than usual. However, they are tailored to using the Seta with Channel D Pure Vinyl’s digital vinyl compensation curve. The required gain is about 10 to 12 dB less than needed in a conventional phono preamplifier, because the signal is provided to Pure Vinyl with treble emphasis (boost) intact. -

The shield should be connected to the XLR connector pin 1; positive cartridge connection to pin 2, and negative to pin 3. For more information, see the Pure Vinyl User Guide. Take care to confirm that your turntable / tonearm doesn’t connect the chassis ground or common to any of the cartridge signal leads. -
Page 13: Rechargeable Battery Information
Off the shelf or commercially designed battery maintenance circuits aren’t used because they are simply not designed with the ultra low noise requirements of preamplifiers in mind. The Channel D Seta design is fully analog and ultra low noise. AGM Rechargeable Battery Operation and Charging The Seta should always be kept powered, to maintain both a stable circuit temperature and the condition of the AGM battery. -
