Seta - Balanced Direct Coupled Ultra Wide Bandwidth Phono Preamplifiers

       The Lino C 2.0 Current-Mode MC Phono Preamplifier



Seta - Balanced Direct Coupled Ultra Wide Bandwidth Phono Preamplifiers

Balanced, Direct Coupled, Rechargeable Battery Powered, Ultra-Low Distortion, Ultra-Low Noise Current-Mode MC Preamplifier


Current-Mode Design for automatic cartridge load and gain matching

The Lino C 2.0 uses the latest current-mode (transimpedance) circuit technology. A current-mode MC preamplifier uses the current rather than voltage from the cartridge. Cartridge loading and gain setting are automatic. It also improves the cartridge's mechanical damping and tracking! With the Lino C's balanced current-mode inputs, ultra-low-noise, hum-free operation is assured.

New features in the Lino C 2.0:
  • Autobiasing circuit forces input devices into Class A mode for lower distortion
  • Externally accessible gain-structure and mode switches
  • Trigger port supplies 5 volts when charging, for controlling external devices

    Current-Mode improves cartridge tracking through superior damping

    Shown above is the waveform obtained from playing the Hi-Fi News Analogue Test LP 300 Hz +16 dB torture track played with an Ortofon A90 cartridge mounted on a Kuzma 4Point tonearm, set for a tracking force of 2.0 grams. This shows the improved cartridge tracking with the current-mode Lino C compared to our standard voltage-mode Lino (load resistance of 100 ohms). (There is no load resistance setting required with the Lino C current-mode phono stage.)

    External settings

    The mode and gain-structure switches, plus charging "flag" port are presented on the bottom of the chassis. Mode switches allow configuring the balanced outputs for standard phono output or "flat" (gain with no RIAA EQ) for use with digital audio systems. The gain-structure allows matching the output level of the Lino C to your other components (though if switching cartridges, no gain adjustment is required). The charging port allows optional signalling of external hardware when the Lino C automatically enters battery charging mode (an input signal is not detected for 10 minutes). Please see the Lino C 2.0 User's Manual for more information about the use of this feature. The bottom of each Lino C also includes a graph of the measurement of the actual RIAA accuracy of that preamplifier.

    Rechargeable Battery Power Supply

    The low-impedance, internally located AGM rechargeable battery is capable of supplying 50 amperes of current, outperforming other types of batteries used in audio applications. The battery is conditioned and kept float-charged by a proprietary circuit, rather than use an "off the shelf" microprocessor based conditioning and monitoring circuit, which would introduce unwanted noise. Locating the battery inside the preamplifier chassis also insures that the battery is in the same electrical environment as the sensitive front-end circuitry, eliminating potential sources of noise pickup. The external charging supply is automatically disconnected when an input signal is detected. The preamp also may be operated while the battery is charging.

    Mechanical

    Connectors are the best available, professional quality Neutrik gold contact XLR.

    Other design features:

    • Ultra low impedance AGM rechargeable batteries used as charge storage reservoir and power supply filter; proprietary, exclusive charging and maintenance circuitry specially designed by Channel D and proven, refined and used exclusively in our phono stage designs for over 9 years
    • True single ended outputs obtained by differential summing and balanced signal input for lowest possible noise (high common mode rejection) on single ended connections
    • State of the art, premium quality low - ESR polymer dielectric electrolytic and tantalum filter capacitors
    • Ultra precision (0.1% tolerance) metal film low noise resistors used throughout
    • RIAA Compensation uses precision, hand selected and matched components, and is accurate to better than +/- 0.1 dB
