® sE Electronics DM1 User Manual
Thank you! We would like to thank you cordially for choosing this sE DM1! We hope you enjoy using it as much as we enjoyed designing and building it for you. The DM1 is an active inline preamp intended to be inserted between a passive ribbon or dynamic microphone and a microphone preamplifier.
Powering To ensure proper operation, the DM1 requires a phantom power source providing 48 Volts according to IEC 61938. Risk of Damage Do not connect the DM1 to any power supply other than a phantom power source (input with phantom power or external IEC standard phantom power supply) with a floating connector, using a balanced cable with studio grade connectors to IEC 268-12 only. This is the only way to ensure safe and reliable operation.
