ATC-7 Tube Linestage Preamplifier By Air Tight

The ATC-7 linestage preamplifier by Air Tight redefines audio enjoyment by bringing back the tactile pleasure of physical controls in a world of digital convenience. Unlike modern touch panels and smartphone controls, the ATC-7 celebrates the joy of adjusting the sound with precision-engineered knobs that provide a satisfying tactile response. Air Tight meticulously redesigned these controls to offer the perfect texture and rotation feel.

In the quest for the ultimate sound quality, no effort or time was spared. The ATC-7 features an advanced power supply with ultra-high-performance regulation and a choke coil, housed in a robust Bakelite and steel chassis. This design eliminates electrolytic capacitors to enhance transparency and fidelity.

The amplifier’s input section includes a mechanical rotary switch and high-quality components to ensure minimal signal loss and crosstalk. It features three RCA and two XLR inputs, with robust PTFE-insulated cables. The amplification section uses a 2-stage NF-type SRPP circuit with twin triodes, housed in a black chrome-plated inner chassis for superior performance.

The ATC-7’s controls include:

1. Presence Control: Fine-tune high frequencies and sound field nuances.
2. Bass Compensator: Adjusts low frequencies for better balance at low volumes.
3. Gain Trim: Allows precise gain adjustment for each channel.

With its unparalleled sound quality, elegant design, and engaging user experience, the ATC-7 is a testament to Air Tight’s commitment to audio excellence.
