The ATC-7 is a preamplifier from Air Tight, built with comprehensive five-input connectivity and a substantial output voltage. The ATC-7 brings Air Tight's considered engineering to line-stage preamplification.
Key specs that matter
Two balanced XLR inputs and three single-ended RCA inputs are provided, with two single-ended outputs. Gain is 19dBu. Output voltage reaches a substantial 20V. Input impedance is a high 100k ohms on both connections, with output impedance at 47k ohms single-ended. Total harmonic distortion plus noise is 0.02% - a figure consistent with a characterful tube-based circuit topology. At 400 x 350 x 145mm and 13.5kg, the ATC-7 represents a substantial preamplifier chassis reflecting quality tube-circuit componentry.
Sound and use context
Expect the rich, harmonically engaging tonal character Air Tight's broader considered tube-circuit engineering philosophy is known for, with the substantial 20V output voltage providing genuine headroom for driving demanding downstream amplifiers.
Pairing
The comprehensive five-input connectivity comfortably accommodates a source-rich system, and Air Tight's own ATM-3211 or ATM-1 power amplifiers offer natural, brand-coherent pairings.
Alternatives
Air Tight's broader amplifier catalogue offers alternatives for buyers wanting a different configuration.
