Inward Connections TSL-4 Vac Rac

Looking for some magic for vocals, bass, guitar, or the mix bus? Pay attention to the TSL-4 Vac Rac stereo tube limiter, the bread and butter of Inward Connection's line of boutique, made-in-LA gear. Loaded with Cinemag transformers, this latest version of the Vac Rac series adds new features without changing the sonic signature engineers have come to revere. You'll be armed with just the right amount of transient control, without having to tweak a bunch of knobs, giving your tracks a buttery-smoothness you'll have to hear to believe.

No-compromise design with dual-mono or stereo operation
The latest incarnation of a mix engineer's favorite
Inward Connections: boutique gear handmade in LA

No-compromise design with dual-mono or stereo operation
Top to bottom and front to back, the Inward Connections TSL-4 Vac Rac is designed and outfitted with premium components and the features pros want from a limiter. The TSL-4 Vac Rac has a link switch, connecting the opto cells of both channels for stereo operation. Both the Gain Makeup and bypassable Gain Reduction controls are 40-detented, offering 14dB of output gain and 40dB of gain reduction respectively. The best of the rest? There's a switchable 250Hz highpass filter, large 3"x3" illuminated VU meter (switchable Gain Reduction or Output), and Cinemag transformer-balanced XLR I/O, all packed into a rugged, well-ventilated 3U steel chassis with a vintage vibe to boot.

The latest incarnation of a mix engineer's favorite
Ever since the Vac Rac series hit the market two decades ago, it's grabbed the attention of high-profile mixers. This latest version gives you the same famously smooth limiting, with all the euphonic character and tube warmth that the Vac Rac reputation has been built on.

Dreamed up and designed by Steve Firlotte, a well-known LA tech, the Inward Connections line offers premium options for the discerning ear, all meticulously handmade in Firlotte's Los Angeles workshop.
