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.

Mesa/Boogie has long been at the forefront of amplifier innovation, and the Mesa/Boogie PMN (Powerful Musical Network) is a testament to the brand’s commitment to exceptional sound quality and versatility. The PMN series is designed primarily for guitarists and musicians seeking a blend of power, flexibility, and tone-shaping capabilities.

One of the main features of the PMN series is its robust power output. With variants that can handle 50 to 100 watts, the PMN delivers enough volume for live performances while also providing the opportunity to dial back the wattage for studio use. This flexibility allows musicians to achieve that desirable "cranked" tube amp sound at lower volumes, making it an excellent choice for in-home practice or studio environments.

Another key characteristic of the PMN series is its advanced tone-shaping capabilities. The amplifiers come equipped with multiple channels, each offering distinct tonal characteristics. Musicians can switch from clean, sparkling tones to rich, saturated overdrives with the flick of a switch. The amp's comprehensive EQ controls allow for detailed adjustments, ensuring that players can sculpt their sound precisely to their liking.

Mesa/Boogie is also known for its innovative technologies, and the PMN series incorporates several cutting-edge features. The "Multi Watt" technology provides options for optimizing power and headroom according to the player's preferences and needs. This design allows the amp to operate in different power modes, giving artists the option to tailor their sound further.

Additionally, the PMN series includes the "Graphic EQ" feature which allows players to visualize and manipulate their sound in real-time. This interactive aspect of tone shaping helps musicians develop their own unique sonic signature.

The construction of the PMN series amplifiers also reflects Mesa/Boogie's commitment to quality. Built from durable materials with a focus on reliability, these amplifiers are designed to withstand the rigors of touring and frequent use. The attention to detail in both craftsmanship and electronics guarantees that players will get reliable performance over time.

Overall, the Mesa/Boogie PMN series stands out as a powerful tool for musicians who demand versatility and exceptional sound quality. With its potent output, advanced tone control, and innovative technology, it serves as a valuable asset for players in a variety of musical genres.
