The Analog line is where Swan Song Audio started building consumer-oriented products. Products include:
- Single Ended Moving Magnet / Moving Coil Phono Preamplifier
- Instrumentation Moving Magnet or Moving Coil Phono Preamplifier
- Instrumentation Transimpedance (I to V) Phono Preamplifier
Single Ended Moving Magnet / Moving Coil Phono Preamplifier
Small but mighty, this small package offers excellent performance. 1 volt rms, or greater, output is supported for 0.4 to 5mv cartridges.
Instrumentation Phono Preamplifiers
The instrumentation line is based on the instrumentation style balanced to single ended amplification methodology. The method is so named because it is this design that is used in sensitive measurement and hospital equipment. Changes to the basic phono include:
- Instrumentation style balanced to single ended first stage amplification
- Digital switching circuitry
- Dedicated as MM, MC, or I to V
- Tighter RIAA tolerances
- Larger chassis
- Additional power filtering and handling capabilities
- Built in volt meter for gain setup, channel balance, and grounding verification
Gain settings are user adjustable from 42 – 74dB for the MM and MC options. This supports cartridge outputs from 0.3 to 6mv. Lower output MCs are handled by the I to V model which supports 30 to 500 microamps output currents as defined by the cartridge output voltage divided by the internal resistance.
The instrumentation line brings the increased detail and low noise levels found in the best of high end phono preamplifiers without the ultra high end price.
Here are two sample clips from the SE Phono and the ADC using a Sumiko Pearl MM cartridge.
Here is the same song used for Sample 1 with the SE Phono. This time it is played through the I to V phono, into the 6SN7, out of the 6SN7, and recorded by the ADC.
Here is a sample of a early 1960's recording through the Instrumentation I to V Phono and recorded by the ADC.
Here is a sample of a early 1960's recording through the Instrumentation MC Phono and recorded by the ADC.
