Brand: Sonotone
The Sonotone 23T is a vacuum tube preamplifier designed for use in audio applications. It provides a natural and warm sound with a frequency response of 10 Hz to 25 kHz (+0/-3 dB). This preamp has a high input impedance of 15k Ohms, which is ideal for letting the transformer "see" the full signal while minimizing loading effects on the source. The 23T also features balanced XLR and unbalanced RCA input and output connections, as well as a power switch and LED indicator. Its dual-triode vacuum tubes (AC702/12AX7) provide a smooth and rich sound, making it a popular choice for recording engineers, producers, and musicians who prefer tube-based audio equipment for its unique character and tone.
