Excellent condition Heritage Audio Baby RAM Monitor Controller

I purchased this new several years ago and it has barely been moved from my desk.

There are some minor scratches, but no crackling or other issues, and the condition is good.

It was used without any problems until February 2026.

Thank you.

Desktop Passive Monitoring System
The Baby RAM is a boutique passive monitor controller inspired by classic European consoles. It offers a simple way to build a high-quality monitoring environment by combining an uncompromising signal path with simple controls.

Unlike inexpensive stereo potentiometers, the Baby RAM features a 4-contact, 24-step rotary switch, ensuring perfect stereo signal accuracy at any volume position. Furthermore, the Baby RAM has no loss from cable connections, so there is no unwanted coloration or signal loss.

With an uncompromising circuit design, the Baby RAM is also excellent in terms of ease of use. Operation is clear with two pairs of balanced/ground-free (unbalanced) stereo TRS inputs/outputs with gold-plated connectors, mute, DIM, mono switches, and a large monitoring knob. Of course, being a passive design, no power is required, so there is no worry about power failure.

The Baby RAM is a reference-spec monitor controller born from Heritage Audio's cutting-edge technology, which does not compromise on audio quality.
