BRYSTON INTERCONNECT CABLES

ANALOG/DIGITAL/VIDEO CABLE

We at Bryston, do not think cables should be ‘voiced’ to sound a specific way. The best cable is NO cable at all so we contend that the best cable is the cable that changes the signal the least.

The geometry (where the plus is relative to the minus) of a cable determines the inter-relationship between the measured performance of a specific cable. These measured performance criteria are call the ‘Primary Constants’.They are R-resistance, L- inductance, C- shunt capacitance and G-shunt conductance. You can play around with all types of exotic packaging and add-on appendages you like but ultimately the measured performance (primary constants) tell the tale.

COAX INTERCONNECT CABLES

An analogue Preamp/Amplifier connection is a ‘high impedance interface’ therefore; you are looking for low measured Capacitance. An interconnect cable acts like a capacitor in the signal path so the better that capacitor the better the interconnect. We use an interconnect wire with (very low capacitance) and the RCA connectors are made for us in Switzerland. The RCA cables ‘make and break ground’ first and last when connecting and disconnecting. This prevents ugly pops and bangs from going through your system with the possible negative results.

XLR INTERCONNECT CABLES

The XLR cables we use are also very low in capacitance. Actually the XLR cable we are currently using is in fact low noise balanced microphone cable with 100% shield coverage against RF.The advantage of Balanced XLR cables is that they have a noise canceling effect know as ‘common mode noise reduction’. This helps prevent noise and hum from affecting your system. With today’s complexity of audio and video surround systems this is a big plus, so if you ‘got em-use em’.

DIGITAL CABLES

With ‘Digital’ interconnects things are a lot different. The wavelengths of digital signals are ‘very short’ (same for FM) so the lengths and terminations are much more critical than with the analogue signals previously discussed.When the wavelength of the signal the cable is used for approaches 1/30th of the length of the cable then transmission line effects start to appear and much more attention has to be paid to the connection and termination. If not then reflections and cancellation of data is a real possibility. For instance the AES/EBU digital connection on the back of the Bryston SP2 should be used with a cable having an impedance of 110 ohms.

VIDEO CABLES

Video cables also operate at very high frequencies - typically 5-6 MHz for Composite and S-Video and 8-30 MHz for Component Video depending on the scan rate and resolution. So again understanding the wavelengths of the signals and interfaces involved is important.
