SPEAKER IMPEDANCE MATCHING & HOOK-UP GUIDE: (Continued)

PARALLEL:

When wiring in parallel, the resistance of the speakers decreases. Two 8 ohm speakers wired in ( hooked-up )

 

Parallel results in a 4 ohm load. It’s easy to calculate the effect of a resistive load when all the speakers are all the same resistance. It is really not suggested to wire different resistive load values in Parallel ( 8 and 4, 16 and 8 etc. ) The formula for fi guring the total impedance in Parallel is the multiplication of the two loads divided by the sum of the two loads - i.e. putting two 8 ohm speakers in Parallel results in a 4 ohm load. Connect the Positive side of Speaker A to the Positive side of Speaker B - Connect the Negative side of Speaker A to the Negative side of Speaker B.

This is really just two sets of Series wired speakers connected in Parallel. This is how you maintain a consistent load with multiple speakers. The importance of this is more evident when you have more than one

cabinet to connect to your amplifi er. This is when you need to fi gure out the loads and how to wire them up without applying too low of a resistance on the amplifi er.

Simply connect the Positive side of Speaker A to the Positive side of Speaker C.

Connect the Negative side of Speaker A to the Positive side of Speaker B. Next, connect the Negative side of Speaker C to the Positive side of Speaker D.

pmn specifications

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.
