PHONO CABLES
Signals from MM (Moving Magnet) and - even more so - from MC (Moving Coil) cartridges are highly sensitive to hum, noise and various forms of interferences. The connecting cable between the cartridge and preamplifier must ensure that the minute signal of the cartridge is optimally transferred to the preamplifier and at the same time must reject any unwanted signals from entering the signal path. In usual cables this is not taken sufficiently into consideration. After most thorough analysis of these specific requirements and exacting research the worlds ultimate phono interconnect cables have been designed.
The various versions of Precision Interface Technology® - or short: P.I.T. - phono cables are optimized for the different characteristics of cables and phono preamplifier input stages. Each individual application can be optimized and pristine signal transfer from tonearms to unbalanced, pseudo-balanced as well as true balanced phono preamplifiers is guaranteed.
The fact that the reproduction of existing systems can be improved massively by just exchanging the phono cables is rather enticing. It does not get much easier than replacing a phono cable...
With a Precision Interface Technology® Phono Interconnect clear improvements are guaranteed.
DIFFERENT SOLUTIONS FOR DIFFERENT SYSTEMS
Precision Interface Technology® phono interconnect cables are unique. Their unmatched neutrality is the result of the most comprehensive research and an in-depth understanding of low-level signal transmission. Because of the variety of tonearm configurations, connectors and phono preamplifiers, different systems require different solutions. In the Precision Interface Technology® range specifically optimized phono interconnects for any application are available. These different cable types provide the correct solution for the various cartridge to phono preamplifier interconnections.
FEATURES
Precision Interface Technology® Phono Interconnect cables make exclusive use of FORCESHIELD, a proprietary triple shielding technology. The unique dual bifilar shield guarantees zero inductance and an additional HF shield rejects RF interferences. P.I.T. phono interconnects:
- achieve a signal-to-noise ratio and interference rejection of 132dB (which is 20dB to 50dB better(!) than the other high-quality interconnect cables)
- guarantee optimal shielding from 0Hz to above 100Mhz
- eliminate interference signals by 100% proper conduction to ground
- provide unparalleled shield coverage of 99.9% even when cables are bent (a situation where other cables loose effective shielding).
- feature ultra accurate balancing (magnitudes better than other so-called "balanced" cables).
- are totally transparent and allow the characteristics of the cartridge to pass uncoloured
- provide extremely high rejection of magnetically and electrically induced coupling
- achieve lowest crosstalk
- guarantee very low residual system noise floor resulting in better dynamic contrast and improved signal to noise ratio
- allow absolutely phase accurate signal transfer
- eliminate time smear and preserve time coherence
- prevent skin effect throughout the audio bandwidth
- provide a signal-transfer speed 1000 times faster than needed for perfect audio reproduction
- are carefully optimized with consideration for all variables, including different cartridge types and different types of preamplifier input stages
- employ a completely floating shield
- avoid mechanical strain on tonearm/turntable connectors. P.I.T. cables have much better flexibility and allow the tonarm/turntable to float freely without the often experienced negative influence on the turntable suspension
- are available in many dedicated versions with straight or angled 5 Pin DIN tonearm connectors, precision RCA-Phono and XLR connectors
- carry a lifetime warranty
CABLE TYPES & CONNECTORS
In all P.I.T. cables precision connectors are used. The RCA/Phono connectors incorporate a unique exponentially enhanced contact area that takes into account the tolerances of the usual RCA/Phono receptables. Spring loaded, self cleaning contacts assure proper connection to any receptable. Connecting noises, thumps or impulses that could cause hum and harm the equipment are avoided. The precision machined contacts secure the ground before the signal pin makes contact. Efficient strain relief techniques are used. Manufacturing and soldering techniques of the highest standard are employed. Precision Interface Technology® interconnects are painstakingly handcrafted in Switzerland and come with a lifetime warranty.
ATTENTION!
NEVER use a line level cable between a cartridge and the phono preamp! From the outside P.I.T. Phono interconnects look similar as the P.I.T. line level cables. However, even if the cable coding should have been removed it is still possible to recognize the difference from the outside: cables for phono interconnection have a central grounding wire that line level cables do not have.
SELECTING THE CORRECT CABLE VERSION
The following outlines the various types available with their pertinent part numbers.
CA -25141 - CA -25143
Phono M - XLR M (MC+MM)
Ultra flexible true balanced phono cable.
It allows true balanced connection of MM and MC cartridges to the inputs of true balanced phono preamplifiers (the FM 222).
It must be realized that all phono cartridges are principally balanced. With the usual Phono - Preamplifier interconnection cables these are, however, transformed into an unbalanced configuration. This cable now allows true balanced connection of cartridges and guarantees absolutely singular performance. The entire system can be run in true balanced mode (in conjunction with electronics that are capable of this, the FM 222 when used with the FM 255, FM 266, FM 268 and all FM ACOUSTICS power amplifiers).
CA -25151 - CA -25153
5-Pin DIN angled - XLR M (MC+MM)
Ultra flexible true balanced phono cables.
For direct connection of tonearms requiring an angled 5-Pin DIN connector to the true balanced input of the FM 222. This cable now allows true balanced connection of cartridges and guarantees absolutely singular performance. The entire system can be run in true balanced mode (in conjunction with electronics that are capable of this, the FM 222 when used with the FM 255, FM 266, FM 268 and all FM ACOUSTICS power amplifiers).
CA -25161 - CA -25163
5-Pin DIN straight - XLR M (MC+MM)
Ultra flexible true balanced phono cable.
For direct connection of tonearms requiring a straight 5-Pin DIN connector to the true balanced input of the FM 222. This cable now allows true balanced connection of cartridges and guarantees absolutely singular performance. The entire system can be run in true balanced mode (in conjunction with electronics that are capable of this, the FM 222 when used with the FM 255, FM 266, FM 268 and all FM ACOUSTICS power amplifiers).
CA -25171 - CA -25173
5-Pin DIN angled - Phono M (MC)
Ultra-flexible phono cables for single-ended/unbalanced interconnection of MC (Moving Coil) cartridges. For direct connection of tonearms requiring an angled 5-Pin DIN connector to inputs using standard Phono/RCA receptables.
CA -25181 - CA -25183
5-Pin DIN straight - Phono M (MC)

Precision Interface Technology® provide 99.9% shielding.
Bending an ordinary cable results in lower shielding. P.I.T. cables, however, guarantee optimal shielding efficiency on inside and outside even when bent - thanks to proprietary triple shielding.
A T T E N T I O N:
Non-optimal system installations have been reported due to a rather basic error:
as P.I.T. line level cables and P.I.T. phono cables look similar (some versions use identical connectors but each cable is clearly marked) it may appear they are the same and interchangeable.
This is NOT so !
A phono cable has different requirements than a line level cable and for optimal performance must NOT be used as such (and vice versa).
Actually, it is quite easy to differentiate: the P.I.T. phono cables always have an earthing wire between the two cables, the P.I.T. line level cables do not have such an earth wire.
The fake copies of P.I.T. cables that are being offered in certain countries do - who would have thought ? - not make the abovementioned differentiation. One can often spot a fake P.I.T. cable when they lack the identification number, and/or the serial number, both tags around the cables near the connectors.
A further hint: do not accept the cable if it does not come in the original dark blue velvet pouch printed "Precision Interface Technology".
Buying similar looking cheaper cables (some of the connectors we use are generally available but there still is a difference which, however, is not obvious visually) one may end up with non-optimal system interfacing.
Fake P.I.T.'s are not worth the initial "savings".
Remember: You get what you pay for...
