Frequently Asked Questions - Cab-Link Radial Engineering

Can I use the Cab-Link with any amplifier?

No, the Cab-Link is designed for amplifiers with standard speaker outputs. It is strictly prohibited for use with amplifiers that have bridged or balanced (Class-D type) speaker outputs, as it may cause electrical shock.

How do I connect my amplifier to the Cab-Link?

First, turn off your amplifier. Then connect your amplifier to either the FROM AMP SERIES or FROM AMP PARALLEL input, depending on the desired configuration. Never connect to both inputs simultaneously.

What happens to impedance when using series vs. parallel?

In parallel configuration, total impedance decreases (e.g., two 8Ω cabinets = 4Ω load). In series configuration, total impedance increases (e.g., two 8Ω cabinets = 16Ω load). Always match the amp's output impedance to the total load.

Can I connect two different impedance cabinets?

No, both cabinets must have the same impedance (Ohms). Mixing different impedances is not supported and may cause improper operation.

What is the Line Out used for?

The Line Out allows you to feed another amplifier or effects device. It has an adjustable level control. It cannot be used to drive a third speaker cabinet.

Do I need external power for the Cab-Link?

No, the Cab-Link is 100% passive and requires no power supply.

What is the maximum power handling?

The Cab-Link can handle up to 400 watts maximum power.

What type of cables should I use?

Use heavy-gauge speaker cables and keep lengths as short as possible to minimize signal loss.

Is the warranty transferable?

Yes, the Radial 3-year warranty is transferable to subsequent owners, provided the original invoice is included.

How do I clean and maintain the Cab-Link?

Disconnect all cables. Wipe the enclosure with a dry, lint-free cloth. Do not use solvents or cleaners. Store in a dry place.

CAUTION STATEMENT

Please read before connecting your Radial Cab-Link

ALWAYS TURN YOUR AMPLIFIER OFF BEFORE CONNECTING OR DISCONNECTING THE CAB-LINK.

It is your responsibility to confirm the Cab-Link is connected properly before operating your amplifier. If you are unsure about connecting or operating the Cab-Link consult a qualified technician or see your dealer. Damage caused by improper operation is not covered under the warranty. See the back cover for warranty details.

CAUTION - USE OF THE CAB-LINK WITH AMPLIFIERS WITH BRIDGED OR BALANCED SPEAKER OUTPUTS IS STRICTLY PROHIBITED.

These types of circuits, typically a type of a Class-D design, are not suited for use with the Cab-Link. Using the Cab-Link with them may cause an electrical shock and therefore Radial Engineering Ltd. strictly prohibits use of the Cab-Link with such amplifiers. Please consult the amplifier manufacturer to ensure the power output section of your amp is not designed this way.

FEATURES

1. FROM AMP SERIES: Connect your amplifier to this input when using in series configuration.
2. FROM AMP PARALLEL: Connect your amplifier to this input when using in parallel configuration.
3. SPEAKER A & B OUTPUTS: Connect to the inputs of your two speaker cabinets.
4. LINE OUT: Additional output can feed another amplifier or effects device.
5. LEVELS: Adjusts the signal level of the Line Out.
6. 14-GAUGE STEEL: Solid steel enclosure ensures the Cab-Link will handle the most rigorous touring environments.

MAKING CONNECTIONS

The Cab-Link is completely passive with no need for power. When connecting your amp head and cabinets to the Cab-Link, always ensure that you are using heavy-gauge speaker cable, while keeping cable lengths as short as possible. Start with your amp powered down to eliminate plug-in transients.

Before making connections, check the impedance of each of your cabinets; this will be rated in Ohms ( ). This value should be the same for both cabinets, do not mix cabinets that have different impedances. Once you have verified both cabinets have the same impedance, connect them to the SPEAKER A and SPEAKER B outputs on the Cab-Link.

Next, check the impedance of your amplifier output. Some amps will have a switch that will allow you to select the output impedance, while others may have multiple outputs with differing impedances. The guide on the top of the Cab-Link will let you know whether to use the FROM AMP SERIES or FROM AMP PARALLEL input. (Always ensure that you use only one or the other — never connect to both inputs simultaneously.)

Warning: Do not use both inputs of the Cab-Link simultaneously

When connecting your cabinets in parallel configuration, the overall impedance decreases (two 8Ω cabinets wired in parallel will present a 4Ω load).

In series configuration, the impedance they present to your amplifier increases (two 8Ω cabinets wired in series will present a 16Ω load).

    I["PARALLEL"] --> J["8 Ω"]
    K["SERIES"] --> L["4 Ω"]
    M["8 Ω"] --> N["16 Ω"]

The Cab-Link allows you to choose which wiring configuration you want to use by selecting the SERIES or PARALLEL input. For optimal results, always make sure that the output impedance of your amplifier matches the impedance of the load you are connecting to it. For example, if you have two 8Ω cabinets and a 16Ω amp, you would need to connect using series wiring configuration. With the same two 8Ω cabinets and a 4Ω amp, this would require using parallel configuration and connecting to the FROM AMP PARALLEL input.

Ensure that both cabinets have the same impedance in Ohms (Ω).

LINE OUTPUT

The Line Output on the Cab-Link is an additional feature that allows you to feed the input of another amplifier or an effects device. This output is adjustable via the level control on the side of the Cab-Link, and you can connect to it using standard guitar cables. Note that this output cannot be used to feed a third speaker cabinet.
