SL 29 Phono Interconnect - RCA

The new SL 29 Phono interface features upgraded MIT articulation networks developed with technology derived from our SL series interconnects. New and smaller networks that are remarkably easy to match allow Multipole circuitry to become more focused and significantly quieter than any conventional phono interface.

Bruce Brisson insisted on three reference requirements that the SL 29’s “350” network enclosure should provide, with a target price of “less than $5000”:

1. More Poles of Articulation – Multipole technology, tuned to the exact analog frequencies that create a seductive sense of “liquidity” most commonly associated with the sound of analog tape or vinyl recordings. 
2. A silent background– Quanti-Shield technology. MIT looked at new shields and discovered that more is better along with improved grounding circuits to create an “empty ” canvas” to “paint” on.
3. Impedance Matching Network– to make cartridges and stage amps or preamps work with less reflection and less noise insertion from reflected energy. 

Features and Benefits:
  • Hand wound coils— known for more natural timbre and combined “through-mount” hand soldered PC technology
  • “SIT” Stable Image Technology— critical to image definition and creation of the sonic envelope, or space
  • Impedance matching— tune your phono interconnects to various cartridge impedances
  • RCA, DIN or XLR connections (XLR Special Order Only)

are specifically designed for the unique problems that cartridges and phono preamps present. Cartridges generate extremely low output levels, with “high” output cartridges putting 1/1000th the signal level of a typical CD player or other line level source. Noise picked up by the cable can easily distort that signal. Additionally, the terminating impedances of most phono preamps are very different from typical line level inputs. This will alter the articulation of the cable if not designed with that in mind.

To solve both problems, MIT uses a unique Quanti-Shield design for noise-free playback, and unique networks with selectable impedance settings (100 Ohm, 1 KOhms and 47 KOhms) in order to get the most from your records.
