Giving superb performance in its own right, Pulse-XS Speaker Cable is second only to Pulse-XS Reference. Terminated with Vertere Special connectors.
Pulse-XS is similar to the Reference version, utilising the same unique Pulse-XS Cable, but terminated in Vertere Special high performance 4mm Banana or Spade connectors. Pulse-XS signal conductor is also fully shielded to provide highest performance second only to the Pulse-XS Reference.
Integral Jumper (ITJ) Option
Where the speaker has more than one pair of input terminals, ITJs allow terminal connections without the necessity of using compromised binding post links. Any number of ITJs can be incorporated.
Bridged Balanced Type
Pulse-XS is terminated in Bridged Balanced mode suitable for all amplifier speaker outputs. It is important to realise that the bridged outputs are effectively two power amps, where ‘Black’ terminals are joined together and unused – a floating ground system.
The two ‘Red’ terminals then become the new Red and Black terminals. Here one of the amps is inverted which results in an overall output twice the single amp output – twice the power. In this bridged balanced mode both the red and the black terminals are AC audio signal and require exactly the same type of signal conductor for connection to the speakers.
Pulse-XS terminated Bridged Balanced has two signal conductors identical and shielded for optimum performance.
Single Ended Type
Generally a power amplifier’s ‘Black’ output terminal is in fact connected to the amplifier signal ground and carries no signal.
This is the DC Zero reference for the ‘Red’ terminal which carries the entire audio AC signal. For this reason the Pulse-XS can be terminated with its ‘Black’ conductor different to the ‘Red’ to suit DC zero reference better. This could marginally enhance performance.
‘Red’ signal conductor remains shielded and the Cable ID would be marked – Single Ended.
