Finish and Grill

All models- wear resistant textured paint finish with powder-coated perforated steel grill

Notes:

 

 

 

1- Maximum Peak SPL: Calculated by adding the loudspeaker’s sensitivity (1W at 1m) to the peak power (dBw) of the amplifier provided.

2- Coverage: Included angle between -6dB points, plus X, minus Y dB, 500 to 3.2k Hz, taken at ISO preferred one-third octave intervals, or for an otherwise specified frequency range.

3- Directivity Index (DI): Difference between on-axis SPL and average SPL (considering all axes) for the specified coverage range. DI= 10 log Q

4- Directivity Factor (Q): Directivity index expressed as a power ratio Q=10 exp DI/10

5- Amplifier Power: The maximum sustained power at less than 1% clipping, averaged over the intended frequency range,

6- Input Sensitivity: The sine-wave input voltage required to reach amplifier clipping, measured within the frequency range used to determine Maximum Peak SPL, with the gain on “normal” and no gain reduction due

to limiting.

 

7- Input Headroom/Clipping: Maximum input voltage.

 

8- Input Connector/Impedance: RF shunt capacitance should not reduce impedance by more than 30% at 20k Hz.

MD-FP122/64r, MD-FP122/94r specifications

QSC Audio has long been recognized for its commitment to delivering innovative audio solutions tailored for professional applications. Among its standout offerings are the MD-FP122/94r and MD-FP122/64r loudspeakers, both of which are designed to meet the rigorous demands of live sound reinforcement and installation projects.

At the core of these models is their exceptional acoustic design. The MD-FP122/94r features a 12-inch low-frequency driver complemented by a 1.75-inch high-frequency compression driver mounted on a unique waveguide. This configuration allows the speaker to deliver impressive clarity, depth, and coverage, making it highly effective for both live performances and permanent installations. The MD-FP122/64r, while sharing a similar foundation, is optimized for different applications, featuring a 64-degree dispersion pattern that enhances audience coverage within various venue sizes.

Both models utilize advanced materials in their construction, ensuring durability without compromising audio quality. The enclosures are built using high-density plywood that minimizes unwanted resonance and vibration, resulting in clearer sound reproduction. Additionally, both speakers come equipped with a robust, weather-resistant finish, allowing them to withstand the rigors of outdoor environments.

The MD-FP series also supports QSC’s proprietary technology, including their PowerWave™ design. This sophisticated approach maximizes the efficiency of the low-frequency driver, providing enhanced power handling and extending overall performance. Dynamic range is also optimized, allowing users to experience a full spectrum of audio, from the softest whispers to the most thunderous bass.

The integration of user-friendly features further enhances the versatility of the MD-FP122/94r and MD-FP122/64r. These speakers include multiple mounting options to accommodate various installation scenarios, making them suitable for both portable and fixed applications. Additionally, the models are designed to work seamlessly with QSC's Digital Signal Processors (DSP), allowing for tailored tuning to meet specific acoustic needs and ensuring optimal performance across different settings.

In summary, QSC Audio's MD-FP122/94r and MD-FP122/64r loudspeakers exemplify high-quality design and innovative technology. With their powerful performance, durable construction, and versatile application possibilities, these models represent an excellent choice for audio professionals seeking reliable and high-fidelity sound reinforcement. Whether for touring events or permanent installations, they provide the level of performance required to elevate any audio experience.
