Description

The 1023 Mic Pre/EQ 19" Rackmount with PSU is a handwired, single-channel unit that combines classic analog warmth with expanded tonal flexibility. Built with Carnhill transformers and sharing the same renowned mic and line preamp design as the 1073, it delivers a rich, detailed sound that works beautifully on vocals, instruments, and a wide range of recording sources. The included power supply and compact 1RU rack format make it a practical addition to any studio setup.

What distinguishes the 1023 is its extended equalization section, offering a broader selection of frequencies in both the mid and high bands for more precise shaping. This added control allows for creative interaction between the mid peak and the high and low shelves, giving users greater freedom to sculpt tone in a musical and intuitive way. With its generous gain range, flexible filtering options, and straightforward layout, the 1023 provides a versatile front end for capturing and refining sound with character and control.
