Oehlbach Solution Tube Speaker Cable Connector
41,00 €
Oehlbach Solution Tube is a fully insulated tube connector for connecting speaker cables to speakers, amplifiers, and AV receivers. Its crimp attachment allows the cable end to be assembled without soldering. The solid-metal plug contacts are plated with 24-carat gold. The cable entry accepts conductors up to 6.0 mm². Sold individually.
Oehlbach Solution Tube connector is a fully insulated tube connector for terminating speaker cables. It is designed for connecting a cable to a speaker, amplifier, or AV receiver. The cable entry accepts conductors with a cross-sectional area of up to 6.0 mm². Each connector is sold individually.
Purpose and selection
This connector provides a neat termination for one individual conductor of a speaker cable. It is useful when assembling a new cable or replacing the connectors on an existing cable. The terminal on the connected equipment must be suitable for a tube-style connector.
Before assembly, the most important factor to check is the cross-sectional area of the conductor. The stated limit refers to the area of the metal conductor, not the overall external thickness of the cable. The diameter of the insulation is therefore not a suitable measurement for selecting the connector.
When preparing cables for stereo or multichannel systems, label every cable end according to its channel and polarity. Clear labelling makes installation easier and helps prevent the positive and negative conductors from being interchanged.
Construction and contacts
The connector has a solid-metal plug construction. Its contacts are plated with 24-carat gold, and this version has a gold-coloured finish.
The fully insulated housing separates the metal section of the connector from its surroundings. When several connectors are installed next to one another, the insulation helps keep the individual cable ends organised and clearly separated. It does not, however, identify polarity by itself. The positive and negative conductors must still be distinguished using the cable markings or labels added during assembly.
Assembling the crimp connection
The conductor is secured inside the connector using a crimp connection. After the cable insulation has been removed, the conductor strands are inserted into the designated cable entry. The connector is then crimped with a tool suitable for both the connector entry and the cross-sectional area of the conductor. This method allows the cable end to be assembled without soldering.
The prepared conductor must enter the cable opening completely. No individual strands should remain outside or protrude beside the connector. Avoid stripping away more insulation than necessary, as an excessively long bare section may leave exposed metal extending beyond the insulated housing.
During crimping, take care not to flatten the contact section of the connector. Pressure must be applied to the cable-entry area rather than to the part inserted into the equipment terminal. Once assembly is complete, pull the cable gently to confirm that the conductor is held securely and does not move inside the connector.
No particular crimping-tool type or tool package is specified. Select the tool according to the shape of the connector entry and the size of the conductor being used. Correct positioning is important because the crimp must secure the conductor without damaging the contact portion.
Use in an audio system
The Solution Tube can terminate cables running to speakers and electronic audio components. Its intended applications include connections to amplifiers and AV receivers. Suitability depends on two points: the conductor must fall within the supported cross-sectional-area limit, and the equipment terminal must accept a tube connector of this type.
In a stereo system, the conductors for the left and right channels are terminated separately. In a home cinema system, the cables for each passive-speaker channel are prepared in the same way. The same polarity must be maintained at both ends of every cable, regardless of the number of channels in the system.
If the connector is fitted at only one end of a cable, the other end may use a different termination chosen to suit the terminal on that piece of equipment. Using different connector types at opposite ends does not change the need to connect the positive and negative conductors correctly.
Package contents and quantity planning
One sales unit contains one connector. It is not supplied as a pair or as a four-piece set. Before ordering, count every conductor that will require its own termination.
When both ends of a two-conductor cable are to be fitted with these connectors, a separate unit is required for each conductor at each end. If only one end of the cable is being terminated, connectors are needed only for the conductors at that selected end.

FAQ
What is this tube connector intended for?
It is intended for terminating an individual speaker-cable conductor. The prepared cable can then be connected to a speaker or audio component equipped with a compatible terminal.
Does one sales unit include a pair of connectors?
No. One sales unit contains one connector. Calculate the required quantity by counting all cable conductors that will be terminated individually.
How should I choose the connector for my cable?
Check the cross-sectional area of the metal conductor. Do not include the outer insulation or use the cable’s overall diameter as the basis for selection.
Is the connector suitable for a stereo amplifier?
Yes. It is intended for connecting speaker cables to amplifiers as well as speakers. The amplifier terminal must accept a tube connector of this shape.
Can it be used with an AV receiver?
Yes. An AV receiver is one of the intended electronic components. Terminate the positive and negative conductor of each speaker channel separately.
Is this connector suitable for a multichannel system?
It can be used on the individual cable conductors for passive speakers. The required quantity increases according to the number of channels and the number of cable ends being terminated.
How do I maintain the correct polarity?
Identify the positive and negative conductors before installation. Keep the same connection arrangement at both ends of the cable.
What should I check after crimping the connector?
The conductor should not move or pull out when the cable is tugged gently. There should also be no loose or protruding strands beside the cable entry.
