Product details

The EVE-AT1 is a tribute to the EQ section of the legendary Neve* 1081. The EVE-AT1 was designed with simplicity and clarity in mind, allowing for straightforward usage and immediate productivity. The EVE-AT1 possesses an additional parametric band with expanded Q bandwidth selection in the low-mid and high-mid frequency ranges as compared to the EVE-AT4. In addition, the AT1 implements a different high-pass and low-pass filter, giving the AT1 a slightly more conventional frequency response in these areas. These characteristics mean the EVE-AT1 is suitable for a broad range of musical applications, offering flexibility, versatility and all-round utility.

“AT1 offers much more flexibility, with wider crossover between frequency bands and many more frequency settings. This makes it a much more useful EQ in general, and we found that between the low shelf, low-mid peak and high-pass filter, we could easily shape the lows in kick drums, snares and basses, or scoop and cut undesirable frequencies from keyboards, guitars and acoustic instruments like strings and pianos.” 9/10, Performance & Value Award.
