Tellurium Q SD-RCA Cable

Tellurium Q SD-RCA is an RCA analogue audio interconnect from the Silver Diamond range. Developed after the Silver Diamond speaker cable, it is designed to complement that cable within an audio system. According to the manufacturer, it is intended for systems in which detail, full-frequency-range reproduction and a natural sound are important. Within the Tellurium Q cable family, this model is positioned as the reference interconnect.

What this cable is designed for

The SD-RCA carries an analogue audio signal between components equipped with suitable RCA connections. It can be used between an audio source and an amplifier. It is also suitable for connecting a preamplifier to a power amplifier when both components use RCA connections.

This model is intended for buyers assembling a higher-end analogue signal path. The character of the system is particularly relevant: the priorities are detail, natural presentation and reproduction across the full frequency range.

This is not a speaker cable. It must not be connected to an amplifier’s speaker outputs or to speaker terminals. The SD-RCA is intended solely to carry analogue signals between compatible components fitted with RCA connections.

Relationship to the Silver Diamond cable range

This model was developed after the Silver Diamond speaker cable. Its purpose is to complement a system that uses the speaker cable from the same range.

This combination is relevant when building a consistent Silver Diamond cable chain. The interconnect connects audio components, while the speaker cable connects an amplifier to loudspeakers. These cables perform different functions and cannot replace one another.

The SD-RCA can also be selected and used without a Silver Diamond speaker cable.

Connecting it in a stereo system

In a stereo system, connect the cable from the chosen source’s analogue RCA output to a line-level RCA input on the amplifier. The source may be a player, converter or another component equipped with a suitable line-level output.

Switch off both components before making the connection. Connect the cable to the source output first, then connect it to the amplifier input. The connectors should sit securely without being placed under tension, and the cable should not be bent sharply behind the equipment.

Always choose the correct line-level input for the source being used. The physical shape of an RCA socket does not by itself identify the signal type or purpose. For a digital coaxial connection, choose a cable specifically intended for digital signals.

Use with a turntable and separate amplifiers

In a turntable system, the SD-RCA can be used between the line-level output of a phono stage and an amplifier. A turntable signal must first pass through a suitable phono stage.

In a system with separate amplification components, the cable can connect the RCA output of a preamplifier to the RCA input of a power amplifier. In this arrangement, volume is controlled by the preamplifier, while the cable carries the preamplifier’s output signal.

If the system provides only balanced XLR connections, a different cable type is required for that connection.

Home cinema and multi-component systems

In a home cinema system, this cable can connect a line-level output on an AV amplifier to the corresponding input on a power amplifier.

Every separate signal path requires its own connection. A multichannel system may therefore require more than one interconnect cable. The required quantity depends on the components being connected and the number of channels in use.

The presence of an RCA socket alone is not enough to confirm compatibility. The signal purpose must match at both ends of the chain: an output must be connected to the corresponding analogue input.

Choosing the length and arranging the cable

Before purchasing, determine the actual distance between the RCA sockets that will be connected. Measure more than the space between the equipment cabinets: allow for the complete route the cable must follow behind the components.

Leave a small amount of slack at the connectors so that the cable is not pulled tight. Excessive length can make a neat installation more difficult. The length is not stated in this description, so be sure to check the length of the specific product offered before buying.

Do not route the cable where it will be compressed beneath equipment feet or furniture. Where possible, keep the analogue signal cable separate from power cables. If the cables must cross, it is preferable for them to cross rather than run alongside one another.

Technical specifications

FAQ

Which components is this cable designed for?

It is intended for components with analogue RCA outputs and inputs. This may include a connection from a source to an amplifier or a connection between separate amplification stages.

Can it be connected to speaker outputs?

No. This is an interconnect cable, not a speaker cable. Amplifier speaker outputs and loudspeaker terminals require a separate speaker cable.

Does the SD-RCA have to be used with a Silver Diamond speaker cable?

No. The model was developed to complement this cable range, but it can also be used independently.

Is the cable suitable for a stereo amplifier?

Yes, provided that it is connected to a line-level input. The correct connection method is described in the section titled “Connecting it in a stereo system”.

How should it be used in a turntable system?

Use it after a suitable phono stage. The appropriate connection point is explained in the section covering turntable systems.

Is it suitable for a home cinema system?

Yes, it can be used for individual analogue channels. The number of cables required depends on the number of channels being used.

How should I choose the cable length?

Measure the full cable route, allow a small amount of slack and check the length of the specific product offered before purchasing.

Can the cable be used for a digital coaxial connection?

The SD-RCA is an analogue audio interconnect. For a digital coaxial connection, choose a cable specifically designed to carry that type of signal.
