Knif Audio Solmu Mastering Compressor

Gain reduction is handled by a transformer-coupled MOSFET push-pull topology inspired by classic variable-mu designs. The discrete MOSFET array is tightly matched and thermally stabilized for consistent, predictable performance. The unit’s sonic signature is shaped primarily by the gain reduction stage and custom interstage transformers, while the remaining circuitry is optimized for transparency, bandwidth, and low noise.

Solmu also introduces GR Offset, a unique control that shifts the no-compression point along the gain reduction curve, enabling earlier onset of third-harmonic character.

US and EU parcels ship via UPS, ETA 1-7 working days from pickup day zero. That also applies to most locations worldwide.

All shipments are fully insured.

Bigger shipments requiring pallets or custom made crates ship to US, CA, JP, CN, AU and other outside of EU locations via DHL Air Freight, ETA is normally approx. 7-14 working days from pickup day zero.

Big shipments inside EU ship via different freight companies, recently mostly via ACE Logistics. Freight forwarders can use different courier companies for deliveries to final destinations.

Palletising and crating time can vary depending on the size of the shipment and packaging queue. We pack all our shipments with great care.

You are most welcome to pick your order up yourself from our Retrosonic Pro Audio showroom, studio and warehouse in Tallinn, Estonia.

We ship worldwide – contact us for a personal shipping quote or any other questions.

VAT (Value Added Tax) can be deducted if you have a company with a valid EU VAT number or if you're based outside of the EU. Non-EU buyers pay all and any import tax and duty as regulated by their local customs.
