Tellurium Q UBU-PWR Power Cable

The Tellurium Q UBU-PWR cable is a mains power cable from the Ultra Blue Power range, recommended by the retailer for source components and equipment at the beginning of an audio system’s signal chain. It is primarily recommended for a digital-to-analogue converter (DAC) and components that perform a similar role within the system.

This model can be used in the same system as a Tellurium Q Black power cable. The two cables are designed to complement each other when assigned to suitable components. The retailer recommends Ultra Blue Power for source equipment, while Black is suggested for integrated amplifiers, power amplifiers and mains conditioners.

Which components is this cable recommended for?

The UBU-PWR carries mains electricity from a wall socket to a compatible audio component. It is not a speaker cable or an audio signal interconnect. It should not be used to connect an amplifier output to loudspeakers or to connect a DAC to an amplifier’s signal input.

The retailer primarily recommends it for use at the beginning of the system chain. A DAC converts a digital signal into an analogue signal, but this cable does not carry that audio signal. Instead, it connects separately to the DAC’s mains power inlet.

Keeping these functions separate makes it easier to plan the cabling for the complete system. Begin by identifying which components serve as sources or perform an early-stage role. Amplification and mains-conditioning equipment can then be considered separately and assigned the power cable recommended for that type of component.

Pairing it with Tellurium Q Black

The UBU-PWR can be combined with a Tellurium Q Black power cable in one system. These models do not need to be treated as interchangeable products. The retailer recommends them for different categories of equipment, allowing each cable to be selected according to the role of the component it powers.

Ultra Blue Power is primarily suggested for source and front-end equipment, such as a DAC. Black is recommended for integrated amplifiers, power amplifiers and mains conditioners. This approach lets you distribute the cables according to the purpose of each component rather than choosing one model indiscriminately for every device.

For a system containing only a DAC and an integrated amplifier, the retailer recommends using the UBU-PWR with the DAC and Black with the integrated amplifier. In a system with separate preamplifier and power-amplifier components, apply the same general principle by considering the function of each individual unit.

Choosing the correct connectors

The connectors at both ends of the power cable must match the mains socket being used and the power inlet on the specific audio component. A plug of the wrong shape must never be forced into place, modified or connected using excessive pressure. This is particularly important with DACs, as their power-inlet types can vary.

Before making the connection, compare the component’s inlet with the equipment-end connector fitted to the cable. You should also check the route to the mains socket. The cable needs to reach both connection points without being stretched, placed under tension or bent sharply.

Connection and cable routing

Switch off the audio component before replacing its power cable. Disconnect the existing cable from the mains supply first and only then remove it from the component. Insert the new cable firmly into the component’s power inlet before completing the mains connection.

Route the cable along a relaxed path. Do not leave the connector under tension behind furniture, and avoid pressing the cable into a sharp bend. Leaving a small amount of free cable near the component helps reduce mechanical strain on its power inlet.

Do not wind excess cable into a tight coil. Arrange it in a broader loop instead, respecting the cable’s natural bend. Keep mains cables and low-level signal cables organised so that the connection belonging to each component remains easy to identify when installing, checking or rearranging the system.

Once installation is complete, confirm that both plugs are fully inserted. Only then should you switch on the mains supply and the component itself. If you later change the system layout, disconnect the cable by holding the plug rather than pulling on the cable body.

Its place in a stereo or home cinema system

When planning a stereo or home cinema system, first list all equipment that requires mains power. Mark source components, amplifiers and any mains conditioner as separate categories. This makes it easier to choose a cable according to the role of each device and avoids confusing mains power cables with signal interconnects or speaker cables.

The same selection principle applies regardless of the system’s channel count. What matters is the function of the individual component. A separately powered DAC or another suitable front-end component is the type of equipment for which the retailer recommends the UBU-PWR.

Technical specifications

FAQ

Where in an audio system does the retailer recommend using this cable?

The retailer primarily recommends it for a source or front-end component. A typical recommended device is a DAC with its own mains power inlet.

Can it be used together with Tellurium Q Black?

Yes. Both cables can be used within the same system, with each one assigned to different components according to the retailer’s recommendations.

Is this a DAC signal cable?

No. It is a mains power cable and therefore does not connect to a digital or analogue audio input. It requires a compatible power inlet on the component.

Which cable should I choose for a DAC and an integrated amplifier?

The retailer primarily recommends the UBU-PWR for the DAC and other front-end equipment. A separate Tellurium Q Black cable is recommended for the integrated amplifier.

Can the cable be used in a home cinema system?

The retailer recommends it for a separately powered DAC or another suitable front-end component. The choice depends on the component’s role rather than the number of channels in the system.

How do I choose the correct connector?

Both ends of the cable must match the mains socket and the power inlet of the component being powered. Never attempt to force an incompatible plug into a socket or inlet.

How do I replace an existing power cable safely?

First switch off the component and disconnect the existing cable from the mains supply. Connect the new cable without stretching it or introducing sharp bends.
