CORE - Eurorack Passive Transformer DI Module

Passive Transformer Coupled DI Module with Ground Lift and Signal Attenuator

CORE is a passive transformer coupled direct injection unit for connecting a Eurorack synth to the microphone/line levels in mixers and recording equipment as well as passing the Input signal directly to the Thru connection. CORE features a Sowter 8044 12:1 DI Transformer with a Mumetal core and an XLR connector from Neutrik. Signal Attenuator and Ground Lift controls (both pre-transformer) help you trim the signal as needed. While the audio portion of this module is passive, it can be connected to a Eurorack power supply to provide LED indication of Ground Lift mode - BLUE halo around the transformer for ground connected and a RED halo for ground lift.

While the audio circuitry of the CORE is passive, if you connect CORE to your rack's power supply for the backlighting/ground lift indication, expect that it will draw between 1mA and 4mA.
