Inward Connections

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. 
 
Inward Connections also offers the TSL-4V Vac Rac.  The TSL-4V is the 
TSL-4 equipped with hand-selected and factory-installed NOS tubes.  The 
TSL-4V is a special order item and subject to the availability of tubes 
required.
