SPEAKER IMPEDANCE MATCHING & HOOK-UP GUIDE:

IMPEDANCE: Wiring up speakers to provide the most effective load and making sure that all of them are in phase will help in creating the best sound possible. This is not too diffi cult, as long as you understand a few things about loading and how to connect your speakers to provide an optimal resistive load.

MESA/Boogie amplifi ers can handle 4 and 8 ohms effectively. Never run below 4 ohms in a tube amplifi er unless you are absolutely certain that the system can handle it properly; this can cause damage to the Output transformer. A few amplifi ers can handle 2 ohms effectively without damaging them ( for example the MESA’S Bass 400+ ).You can always have a higher resistance ( 16 ohms, for example ) without damaging results, but too low of a resistance will likely cause problems.

When running a higher resistance ( for example: 8 ohm output into 16 ohm cabinet ), a slightly different feel and response will be eminent. A slight mismatch can provide a darker smoother tone with a little less output and attack. This response is a result of the amplifi er running a bit cooler. Sometimes when using more than one cabinet a mismatch will be the only option.

If you have only a single speaker, you just match that single speakers impedance to the amplifi er, and you are done. In many cases, you will have a number of speakers, and then you must calculate the “load” that the ampli- fi er will need to support. There are generally three ways to wire multiple speakers together. They are as follows:

SERIES: When you wire ( hook-up ) speakers in Series, the speakers resistance ( as measured in ohms ) is additive - i.e. put- ting two 8 ohm speakers in Series results in a 16 ohm load.

LoneStar Amplifier specifications

The Mesa/Boogie LoneStar Amplifier is a standout choice for guitarists seeking a high-quality, versatile tube amplifier that excels in both clean and overdriven tones. Designed for performers who require reliability and tonal variety, the LoneStar is a blend of vintage warmth and modern performance, making it ideal for various musical genres, from blues to rock to country.

One of the main features of the LoneStar is its dual-channel configuration, allowing players to toggle between pristine clean tones and rich, dynamic overdrives. Each channel offers independent tone controls, including bass, mid, treble, and presence, enabling precise sound shaping. The amplifier also includes a unique "Boost" feature on the overdrive channel, which provides an additional gain stage for solos or dynamic passages.

The LoneStar is powered by a quartet of EL84 power tubes, which deliver a sweet, harmonically rich output. This choice of tubes contributes to the amp's tonal character; the EL84s are known for their smooth breakup and dynamic response. Additionally, the amplifier can operate in either 30-watt or 15-watt modes, offering flexibility for both stage and studio environments.

A hallmark characteristic of the LoneStar is its use of the "CabClone" technology, which gives players the ability to silently record or practice by sending a speaker-emulated signal directly to a mixing console or recording interface. This innovation means you can achieve high-quality recordings without the need for a mic'd cabinet.

The amplifier also features a rugged design, with a sturdy chassis and durable tolex covering, ensuring it withstands the rigors of touring. Its aesthetic appeal, paired with its functional controls and footswitch capabilities, makes it a favorite among professional musicians.

With its distinctive tone, versatility, and advanced features, the Mesa/Boogie LoneStar Amplifier has established itself as a modern classic in the amplification world. Whether you are seeking lush clean sounds, soaring leads, or earthy mid-range overdrive, the LoneStar provides all the tools you need to shape your signature sound effectively. For players who appreciate quality craftsmanship and performance, this amplifier is an investment that pays dividends in tonal richness and reliability.
