The PMC IB1S-A is an active version of the renowned PMC IB1S studio monitor, designed for professional use in recording, mixing, and mastering environments. PMC (Professional Monitor Company) is known for its high-end, transmission-line speakers, which deliver outstanding precision and clarity across the frequency spectrum. The IB1S-A is highly regarded for its accurate sound reproduction, extended bass response, and neutral sonic character.

Key Features of the PMC IB1S-A:

1. Driver Configuration:
2. • Tweeter: 34mm (1.34 inches) soft dome for high-frequency detail and clarity.
   • Midrange: 75mm (3 inches) fabric soft dome, designed to handle the critical midrange frequencies with precision and smoothness.
   • Woofer: 250mm (10 inches) carbon fiber/Nomex piston driver for low frequencies, designed to handle deep bass with control and minimal distortion.
3. Transmission Line Design:
4. • PMC’s Advanced Transmission Line (ATL) technology is a key feature, which enhances low-frequency response by efficiently using the rear sound energy from the bass driver. This design extends bass performance and reduces distortion compared to traditional ported or sealed designs.
   • The transmission line allows the bass driver to deliver deep, clean bass at both low and high listening levels without the typical “booming” or loss of clarity that some other systems might exhibit.
5. Amplification:
6. • The IB1S-A is an active monitor, meaning it comes with internal amplification designed specifically for each driver.
   • Each driver is powered by its own Class A/B amplifier, delivering a total power output of approximately 530W:
   • • 300W for the woofer,
     • 100W for the midrange driver,
     • 130W for the tweeter.
7. Frequency Response:
8. • Offers a broad frequency response, typically ranging from 25Hz to 25kHz, providing clear, extended bass, a detailed midrange, and smooth high frequencies.
9. Cabinet Design:
10. • The IB1S-A features a rugged, studio-grade cabinet with a front-facing transmission line vent for controlled low-end dispersion.
    • The cabinet is designed to reduce unwanted vibrations and resonances, ensuring clean, uncolored sound.
11. Sound Signature:
12. • The IB1S-A is known for its neutral and transparent sound signature. It delivers a highly accurate representation of the audio signal, making it ideal for critical listening environments like mixing and mastering studios.
    • Its combination of a midrange dome driver and transmission line bass gives it superb clarity and detail in both vocal and instrumental reproduction.
13. Applications:
14. • Due to its precision and power, the PMC IB1S-A is widely used in professional studios for mixing, mastering, and post-production.
    • It is suitable for nearfield or midfield monitoring in larger studio spaces where full-range, accurate monitoring is crucial.
15. Build Quality:
16. • As with other PMC products, the IB1S-A is handcrafted in the UK, featuring top-tier components and meticulous attention to detail. This ensures long-term reliability, even in demanding studio environments.

Comparison to Other Models:

• The IB1S-A shares a similar design philosophy with other PMC models, particularly the IB2S, but the IB1S-A is generally considered more compact while still delivering excellent performance for its size.
• The active nature of the IB1S-A eliminates the need for external amplification, offering a more streamlined setup without sacrificing control or precision.
