Based on the topology of Inward's original TLM1 modular processing system, the TSL4 is a stereo compressor that adds tube warmth, euphoric character and smooth limitation to your mix. The TSL-4 lends its talents best to vocals, and also instruments such as guitar and bass.

Nearly two decades ago, Inward Connections created the TLM-1 (Tube Limiter Module) for their Vac Rac modular processing system. The TLM-1 was highly favored by many of the world’s top recording engineers and when the modular Vac Rac was discontinued, the TLM-1 topology found life as a new standalone, dual-channel unit. Thus, the TSL series was born. 

The Inward Connections TSL-4 Vac Rac is the latest incarnation of this classic design. It adds new features without altering the sonic signature engineers have come to revere – Smooth limiting presented with the euphonic character and warmth of tubes. If you want to control the transients of vocals, guitars, bass or the mix bus, without tweaking a whole bunch of controls, the TSL-4 is exactly what you’ve been looking for.
