An analog icon, redefined for today's producer.

The Avalon VT-747SP combines a tube/discrete modeled Class A opto-compressor with a musical six-band program equalizer, as well as output level and gain reduction metering. Ideal for signal conditioning, stereo buss compression and EQ, stereo keyboards and mastering applications.

Kazrog Avalon VT-747SP Native

Avalon VT-747SP Native was developed by Kazrog in conjunction with Avalon Design, and is meticulously modeled upon their hardware, carefully studying multiple units over the course of 2022 and 2023. We believe it is the most accurate digital representation of Avalon's legendary analog hardware to date, and we are honored to have been selected to model this incredible piece of hardware.

"Kazrog has blown through the limits of digital plugins and taken hardware modeling to another sonic dimension... excellent delivery of our Classic Sound!"

- Wynton R. Morro (President, AVALON DESIGN USA, Nashville, TN)

Demo limitations: 

  • Random silent output
  • Preset save disabled

Kazrog plugin demos are time-unlimited, but have the above limitations. Purchasing the plugin removes these restrictions. 


  • Full dynamic control from soft compression to hard-knee limiting can be achieved with master threshold, compression ratio, attack and release controls.
  • Gain reduction indication is a large analog-style VU meter.
  • Low and High Frequency (LF and HF) contour parametric spectral controls can be routed into the internal side-chain path for enhanced frequency dependent compression with variable frequency and threshold levels.
  • SC LISTEN switch  provides side chain listen mode for easy monitoring, or creative EQ applications.
  • 6 band graphic EQ models the smooth characteristics of an all passive design. The frequency turnover, Q and amplitude ranges have been carefully chosen for each band to provide the most natural harmonic balance with lowest phase change while offering simple and effective tone control.
  • Graphic EQ can be placed pre or post compressor for enhanced versatility.
  • TSP (Tube Signal Path) which gives you the choice of either tube tone (utilizing three virtual high-voltage dual triode tubes), or the classic, Class A discrete transistor sound (utilizing virtual discrete transistor amplifiers) in the primary opto buffers and output stages.

Great product

Avalon 747 is performing as expected

Perfekt sheen

Love it, use it on almost every track! Extremely versatile! It’s got that perfect highend feel, and the compressor is superb!


This is one of the kind tool that is must have in you DAW if you want fast result, very impressive work like a champ, I wish there’s more options in live performance but overall it’s the best.

Must Have Unit

The Avalon VT-747SP is a miracle worker. The compressor is super robust and can be pushed much harder than I would normally push a compressor of any type. Achieving that Hi-Fi airy sound without unwanted sibilance using the compressor and EQ combo is easy. The presets are super interesting and useful as well. It's not just a work-horse, it's enjoyable to use and experiment with.

New level of plugin-fatness

Feels fat, like hardware-fat. I feel every tiny tweak, which to me is very hardware-like. Excellent work!
