Connecting an amplifier head to a cab, or speaker cabinet, is a simple process. However, there are factors to take into consideration so that you don't damage your amp. Most importantly, always use a speaker cable when connecting an amp head to a speaker cabinet. Although it looks similar to a speaker cable, an instrument cable can cause damage to your amp head.
Plug one end of a speaker cable into the output jack of your amp head. If the outputs of your amp head have different impedance, choose the one that matches your speaker cabinet. For instance, if your cabinet is rated at 8 ohms, plug the cable into the eight-ohm output of your amp head.
Plug the other end of the speaker cable into the input jack of your speaker cabinet. If using multiple speaker cabinets, plug another speaker cable into the output jack of your speaker cabinet. Then plug the other end of the speaker cable into the input jack of another speaker cabinet. Connecting speaker cabinets in this way is called wiring in parallel. When you combine two speaker cabinets rated at the same impedance in parallel, the impedance drops in half. For instance, if using two eight-ohm speaker cabinets wired in parallel, the total impedance becomes four ohms. Fewer ohms mean less resistance.

Make sure the speaker cabinet can handle the power of your amp head. Solar still for boats for sale by owner. If your speaker cabinet can handle 200 watts at eight ohms, make sure that your amplifier does not output more than 200 watts at eight ohms.
Warning
Never plug an amp head into a cabinet rated at lower impedance than the output of the amp head. Doing so could damage the amplifier.
A half stack is a guitar amplifier setup consisting of an amp 'head' and a single 4x12 feet speaker cabinet. The amp head is typically placed on top of the cabinet. This configuration is so named because many professional guitarists began using two 4x12 cabinets with an amp head on top, or a 'full stack,' in the early 1960's. Half stacks became popular as live sound reinforcement systems improved, and the need for high stage volumes decreased. A half stack is simple to set up with a few cables.
Place your amplifier on top of your speaker cabinet so it sits level and secure.
Locate the impedance rating of your speaker cabinet. This rating should be clearly labeled near the input jack on the back of the cabinet.
Connect a 1/4-inch speaker cable to the input jack of your speaker cabinet. If your cabinet offers stereo connections, start with the left input. 1001 peliculas que hay que ver antes de morir pdf. Connect the other end of the cable to the speaker output jack of your amplifier. If your amplifier offers more than one connection for different impedance ratings, choose the one that is equal to or greater than the rating of your cabinet.
Connect your power cable to a grounded outlet, and connect your guitar to the main input of your amplifier using a 1/4-inch instrument cable.
Tip
If you are using a tube amplifier in your half stack, remember not to power on the amplifier--unless the speaker cabinet is connected to it. This can damage your amplifier.
