Experience the closest to a live musical performance at home with Vertere’s absolute reference Pulse-HB Hand-built Speaker Cable.
The Pulse-HB 4mm & 7mm speaker cable follows the same unique design doctrines and manufacturing precision that is applied to the HB range of interconnect cables. The internal conductors however, are configured to operate at much higher voltages and currents but with the same precision.
Innovative conductor design and signal shielding plus unique mechanically and electrically isolated construction of the Pulse-HB speaker cable provides absolute reference connection between the amplifier and loudspeaker.
Designed with both amplifier output and loudspeaker input requirements in mind, Pulse-HB loudspeaker cable ensures that even the most demanding loudspeakers are in full control of the partnering amplifier. At all times, even during the most complex and yet delicate music passages, almost live performance levels of dynamics, detail and clarity with unparalleled pace and space are unleashed.
The sheer joy and insight into the music when using the Pulse-HB loudspeaker balanced speaker cable is truly extraordinary.
Every Pulse-HB Speaker Cable is fully contact impedance checked against master data, logged and serial numbered. Finally every pair is listened to in our reference monitoring system to ensure perfect matched performance against our reference Pulse-HB speaker cable.
Pulse-HB Speaker Cable is terminated with Vertere HB Reference special 7mm Banana, 4mm Banana or Spade connectors. HB Reference connectors utilise special copper alloy contacts precision machined and 23.95ct hard gold plated to 5 microns.
Single Ended and Bridged Balanced Types
Bespoke and special internal conductor design of Pulse-HB speaker cable allows it to be configured to maximise performance of the loudspeakers with both single ended and bridged balanced power output design amplifiers. At a flick of a switch, this most innovative and unique feature of Pulse-HB 4mm & 7mm speaker cable, optimises the connection to loudspeakers and ensures unparalleled performance whatever the amplifier type.
At this point it is important to clarify the difference between an amplifier with single ended and one with bridged balanced speaker cable outputs. An amplifier with its Black (–) speaker terminal connected to signal ground is technically known as a Single Ended power output. In single ended configuration, the black terminal is fixed at DC zero – ground. No audio signal should be present on this terminal and it should only act as the ground reference for the wideband audio AC signal that is on the Red (+) terminal.
It is also important to appreciate that the (+) and (–) markings on these terminals DO NOT refer to positive or negative DC voltages. In fact any DC voltage present at the speaker output terminal would only be damaging to the loudspeaker. These colours and markings on the terminals are merely to tell them apart and assist in correct connection of the speaker cables and avoid phase reversal. A bridged balanced amplifier on the other hand is essentially two power amps combined into one to make a single channel. In this configuration the ‘Black’ terminals of the two power amps are joined together and are unused – also known as ‘floating ground’. With one of the amps running 180° out of phase to the other, both remaining terminals then carry audio AC signal where the total amplitude is now twice the original – hence twice the power. Here one of the two ‘Red’ terminals is marked as ‘Black (–)’ it is NOT however at DC zero – ground.
Integral Terminal Jumper (ITJ)
Where the speaker has more than one pair of input terminals, ITJs would allow terminal connections without the necessity of using compromised binding post links. Pulse-HB speaker cable ITJ terminations are available in either 4mm banana or spade Vertere HB reference connector. Any number of ITJs can be incorporated.
