1. INPUT Jack – XLR - 1/4” combo input jack for connecting line level signals. The MLI1 can
accept balanced and unbalanced connections.
2. OUTPUT Jacks – Balanced XLR and 1/4” outputs for connecting to a PA system, mixer or
recording interface. The outputs are wired in parallel so you should use only one OUT jack at a
time. The MLI1 outputs can be balanced or unbalanced connections.
3. GROUND LIFT – When the switch is in the LIFT position, the input ground (shield) is
disconnected between the INPUT and OUTPUT jacks. When the switch is in the GROUND
position, the ground is connected through the INPUT and OUTPUT jacks.
If you have two pieces of equipment in a sound system connected to ground through different
AC mains, it can cause a ground loop, which is an annoying 50 Hz or 60 Hz (depending on your
location) hum noise. When the Ground Lift switch on the MLI1 is set to the LIFT position, it breaks
the ground connection between the input and output audio jacks, thereby isolating the output from
the input and removing the hum from an audio signal path. Since both pieces of equipment are still
grounded to the AC mains, they are still safe to use.
The Ground Lift Switch
The Samson MLI1 is a line-level passive isolation box designed to remove
hum and buzz caused by ground loops, or convert unbalanced to balanced
signals. The premium circuitry with a flat frequency response from 10
Hz – 35 kHz (±0.2dB) and durable, roadworthy construction providing
high-quality signal connection solutions for live, broadcast and studio
applications.
The MLI1 transformer delivers an extended, flat frequency response and
ultra-low distortion. The Ground Lift switch isolates the ground from the
Input and Output connections which eliminates hum caused by ground
loops.
