Reference plug & play monitoring

The IB1S-AIII offers reference level quality monitoring in a 3-way plug and play design. It is the ideal monitoring solution for discerning and highly critical professionals in small to medium sized control rooms for all applications including; recording, mixing, broadcast and post-production/mastering applications. No matter the material, whether it is the subtleties of vocal harmonies, strings, or extreme bottom end, their signature transparency and accuracy means that all critical decisions can be made instantly with complete confidence.

Precision soft dome HF & MF drivers provide ultra-high definition and an extremely wide, natural dispersion creating a vivid soundstage over a vast listening area and with PMC’s ATL bass loading technology teamed with its 10” carbon fibre LF piston driver provides identical dynamics and deep defined bass at all monitoring levels.

PMC’s unique ATLTM (Advanced Transmission Line) enclosures have taken loudspeaker design to the highest level, using sophisticated cabinet construction, proprietary drive units, and patented absorption materials and techniques. The benefits are enormous compared to the relatively simple sealed and ported designs currently available elsewhere.

PMC’s innovative approach places the bass driver near one end of a long cavity - the ATLTM (Advanced Transmission Line). This cavity is heavily damped with acoustic material specified carefully to absorb the upper bass and higher frequencies radiating from the rear of the bass driver. The lowest frequencies are allowed to pass down the line and emerge from the large frontal vent in perfect phase with the main driver with the vent acting essentially as a second bass driver.

An important benefit of the approach is that the air pressure inside the cabinet, which loads the bass driver, remains consistent. This helps to maintain control of the driver over a wide frequency range and significantly reduces LF distortion. Consequently, the upper bass and midrange detail is not masked by harmonic distortion and the result is PMC’s characteristically transparent midrange, fast, attacking bass, and outstanding clarity.
A further advantage of the ATLTM design approach is greater bass extension and higher SPL capability compared to typical ported or sealed designs of a similar size – even if similar sized drivers are used.

Moreover, the very consistent bass driver loading brings the welcome benefit that the frequency response remains consistent regardless of listening level, and analytical auditioning can be conducted without needing high replay volumes just to achieve an optimal bass response. This is a unique and a very valuable characteristic of PMC’s Advanced Transmission Line.

More detail

Power is supplied by PMC’s own cutting edge 400w, Class-D amplification, which is designed for maximum fidelity, high damping and ultra-low distortion that results in near- instantaneous stop/start control over the entire driver complement. A precision, hand built, 24dB per octave crossover network divides the three frequency bands to the drivers, this ensures each drive unit is working within their optimal range both in frequency and dispersion making for a highly natural, neutral balance.
