Description

The 1023 Mic Pre/EQ 19" Rackmount without PSU is a handwired, single-channel unit that delivers classic analog tone with enhanced control over sound shaping. Built with Carnhill transformers and based on the same respected mic and line preamp design as the 1073, it provides a rich and detailed character that suits a wide range of recording applications, from vocals to instruments. Its 1RU rack format allows for easy integration into studio setups that already have a compatible external power solution.

A key strength of the 1023 lies in its expanded equalization section, offering a wider selection of frequencies in the mid and high bands for more precise tonal adjustments. This flexibility allows for creative interaction between the mid peak and the high and low shelves, giving users greater control when shaping a sound. With a broad gain range, selectable filtering, and a clear, hands-on layout, the 1023 offers a versatile and musical approach to recording and processing audio.
