No-compromise design with dual-mono or stereo operation
Top to bottom and front to back, the Inward Connections TSL-4V 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 100Hz 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.

Inward Connections: boutique gear handmade in LA
Initially one of LA's best-kept secrets, the word about Inward Connections has been sweeping the globe. After all, when you hear guys like Chris Lord-Alge and Eddie Kramer swearing by a brand, you know to pay attention. 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.

The Inward Connections TSL-4V Vac Rac is the TSL-4 equipped with hand-selected and factory-installed NOS tubes in the audio path. GE JAN 6072A’s and GE 12BH7A’s give the TSL-4V its rich, soulful yet articulate voice. It's tone that many feel can only come from tubes of the past. The TSL-4V is a special order item and subject to the availability of tubes required.
