How to Install a Home Theater Preamp
A home theater preamp is necessary when connecting various input sources to an audio output. Some preamps, however, also offer connections for video input and output. Although the device does not actually strengthen or amplify the audio or video signals, it acts sort of like the intermediary for both signal transmitters and receivers.
Step 1 – Position the Preamp in the Home Theater Cabinet
Determine the best location for the device. Make sure that it has sufficient space in the cabinet. The location should have ample opening at the back for the connecting cables to go into. In fact, it is best that the back of the cabinet where the preamp is installed should not have any covering at all. This allows the cables from both input and output devices to connect easily to the device.
Step 2 – Mark All Input Cables
If there are numerous input sources to be connected to a preamp, make sure that each cable is labeled correctly. Use a masking tape and wrap it around the cable just near the plug or connector. Mark the tape with the specific device associated with it. This helps anyone determine all input sources connected to the device.
Step 3 – Connect the Input Sources
Check to make sure that the connecting cables are properly connected to the input device first. Run the cable to the location of the preamp. Find a vacant slot at the back of the device and look for the input cluster. There are numerous input plugs where the connector can be plugged into, but first, determine if the connector is an RCA cable, a coaxial cable, HDMI, or an optical cable. Choose the correct type of plug and connect the cable into it. Ensure that the plug is completely inserted into the slot. Connect as many input sources as necessary.
Step 4 – Connect the Amplifiers
In order for the input signals to be received by an amplifier or a receiver, connect an amplifier to the preamp as well. The amplifier or receiver should be connected to the output cluster at the back of the device. Find the corresponding connector in the output portion and connect the corresponding amplifier or receive cables into it. You can also connect more amplifiers or satellite receivers into the preamp if there are any.
Locate the input plugs at the back of the amplifier or receiver and connect the cables. When the preamp receives audio signals from any type of audio source, the amplifier also receives the signal and strengthens it as it produces an output audio.
Step 5 – Test the Installation
Read the user's manual to get a good idea on how to operate the device correctly. Connect the input source, the preamp and the amplifier to a power source. Play an audio file in the input source and adjust the volume on the amplifier or receiver. As soon as the audio file is played, the amplifier should also produce an output audio.
