IMPORTANT
XLi Series amplifiers require Class 2 output wiring.
MAGNETIC FIELD
CAUTION! Do not locate sensitive high-gain equipment such as preamplifiers or tape decks directly above or below the unit. Be-cause this amplifier has a high power density, it has a strong mag-netic field which can induce hum into unshielded devices that are located nearby. The field is strongest just above and below the unit.
If an equipment rack is used, we recommend locating the amplifier(s) in the bottom of the rack and the preamplifier or other sensitive equipment at the top.
FCC COMPLIANCE NOTICE
This device complies with part 15 of the FCC rules. Operation is sub-ject to the following two conditions:
- This device may not cause harmful interference, and
- this device must accept any interference received, including interference that may cause undesired operation.
CAUTION: Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equip-ment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to ra-dio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

Frequently Asked Questions
Four speakers that are perfectly matched and a top-notch 2-channel amp make up the ultimate system. Find the positive and negative terminals of the amplifier. By observing the straightforward + and – signs, you may identify the model of an amplifier.
In an amplifier, a stereo pair of channels can be bridged into a single mono output channel. Bridging is widely utilised to increase the power of massive full-range speakers in a two-channel system or home theatre as well as larger passive in-room or in-wall subwoofer speakers.
You can, and it’s usually safe to do so. It is feasible to do this with a wide variety of guitar amplifier types, but it is doable with any guitar amplifier that has two primary inputs. However, you must proceed with caution because sending two signals through an amplifier with a high gain will damage the amplifier.
In a two-channel setup, there are in fact two (well explained) ways to connect a powered sub. Submit the speaker line from your amplifier to the speaker, and then use another set of speaker cables to connect your speakers.
Before being transferred to an external source, the audio signals from an audio source are amplified by a 2-channel amplifier. In addition to being frequently used in vehicular audio systems, it can be used in home theatre systems and other audio applications.
As many speakers as your amplifier can handle can be linked together. A two channel amplifier can have four speakers connected to it either in series or in parallel. The impedance levels and constraints of the amplifier and speakers together determine which one to choose.
Due to the likelihood that they will notice each other and frequently blow fuses, activate protection, or entirely blow up, two amps cannot be connected to a single set of speaker terminals.
A two-channel amplifier can be connected to six speakers either in series or in parallel. Which path you choose should depend on the speakers and amplifiers you have. The range and boundaries of their impedance should be taken into consideration.
A stereophonic audio-frequency amplifier, often driven by a single power source mounted on the same chassis, with two independent amplifiers for each of the two sound channels.
Start by connecting the positive terminal of the amplifier to the positive terminal of the first speaker. After that, connect the second speaker’s positive terminal to the first speaker’s negative terminal. Once a simple chain series of connections between all four speakers has been built, keep repeating this.
A two-channel amplifier can really power three speakers. To achieve this, wire two speakers in parallel or series, then connect the junction circuit to one side of the amplifier. The other side of the amplifier can then receive the last speaker.
Single-channel guitar amplifiers are great for pedal platform amplifiers even if they cannot be adjusted between different levels of distortion. The clean, crunch, and high-gain channels on guitar amplifiers with two channels, on the other hand, are all separate. As a result of being able to switch between different tones, a player becomes more adaptable.
Parallel and series connections are the only real ways to connect two speakers to a single amplifier. If the impedance of your speakers is 8 ohms or greater, you can usually connect them in parallel. If the total impedance of your speakers is less than 8 ohms, connect them in series.
Before being transferred to an external source, the audio signals from an audio source are amplified by a 2-channel amplifier. In addition to being frequently used in vehicular audio systems, it can be used in home theatre systems and other audio applications.
Series wiring will yield the best results when four speakers that are similar to one another are used. You must also validate that your 2-channel amp is of high calibre and is more than capable of concurrently driving all four speakers. First, connect the positive terminal of the amplifier to the positive terminal of the first speaker.
