The AudioScape MK-609 is a high-performance Precision Stereo Diode Limiter/Compressor that combines vintage charm with modern functionality, offering professionals precise control over dynamics and tonal shaping.
The MK-609 draws from the iconic 33609, renowned as one of the most classic bus compressors ever made. Based on the revered 2254 design from 1969, the MK-609 preserves the sonic character of British audio heritage while incorporating modern features suited for today’s studio requirements. The original 2254 was a cornerstone in vintage British consoles, known for its distinctive diode-bridge circuit topology. This circuit continuously monitors the side-chain, using its control voltage to adjust the compression, which results in subtle dynamic shaping across a mix.
The MK-609 features two independent channels, each equipped with separate LIMIT and COMPRESS sections. Both sections offer individual Threshold and Recovery controls, with the Compressor section also featuring a Makeup Gain control and a variable Ratio switch. Users can bypass either section to fine-tune their dynamic control. The high-pass filter on the side-chain enables precise control over how compression is triggered, with options for 50Hz and 100Hz settings. This filter ensures optimal performance across various types of content, offering flexibility for modern workflows.
Another key feature of the MK-609 is the inclusion of a “Super Fast” attack setting, available on both the limiter and compressor. This setting ensures that the MK-609 can handle fast transients, particularly useful for kick and snare drums, which were less efficiently addressed by the original design. The Super Fast mode delivers superior transient control, allowing the MK-609 to tackle percussive sources with precision while maintaining musicality. The design retains the harmonic richness typical of British audio equipment, yet offers greater versatility than its predecessors, making it ideal for bus compression, vocals, and dynamic instruments.
The MK-609 is designed for a seamless fit in both modern digital and analogue studios. In Stereo mode, the unit performs as expected, with transparent compression and limiting. The optional Quad mode expands the possibilities by linking multiple MK-609 units together for larger setups. This makes it particularly suited for complex sessions requiring extensive dynamic control.
In a notable improvement over earlier versions, the MK-609 offers Makeup Gain even when the Compressor section is bypassed. This is an essential feature when using the unit solely as a limiter, allowing users to maintain the desired output level without the need to engage the compression section. For those who prefer the original configuration, AudioScape provides a reversible jumper inside the unit to switch back to the classic design.
AudioScape has gone to great lengths to ensure the MK-609 stays true to its roots while elevating its capabilities. The unit incorporates a range of rare components, sourced from global surplus markets. Notably, the U410 silver can dual FET, an obsolete part from the original Metal Knob design, plays a critical role in maintaining the original sonic signature of the 33609. The MK-609 also features the same BC184C NPN and BC214C PNP transistors as found in the vintage units, ensuring the characteristic sound remains intact.
The MK-609 is constructed with the same attention to detail, using high-quality parts such as the original JAN blue 1N4153 diodes and military-grade power toggle switches. The internal layout and design closely follow the original, ensuring that the tonal qualities that define the vintage version are preserved, down to the smallest detail.
The MK-609's development involved years of research and careful consideration of every component to create a product that would meet the demands of today's audio professionals. It is hand-built in small batches in the USA, ensuring each unit is crafted to the highest standards of performance and reliability. AudioScape’s commitment to preserving the essence of classic designs while integrating modern enhancements results in a versatile and dependable tool for professionals across genres.
The MK-609 is a perfect choice for engineers seeking an authentic vintage compressor with the flexibility to tackle modern production challenges. Whether it’s for subtle stereo bus compression, precise vocal treatment, or controlling dynamic peaks in drums, this unit offers the precision and tonal character that seasoned professionals demand.
