Emtech Electronics SMG105 User Manual

SMG105 Sound Masking Generator

The SMG105 is a sound masking generator designed to be compatible with any brand of
Mixer/Amplifier. It generates a soft pink noise that acoustically sounds like air-handling
ducts or vents. It can provide voice privacy, at an affordable cost, for offices or facilities
where privacy enhancement is desired or required. The pseudo-random sequence that
feeds the pink noise low-pass filter on the SMG105, exceeds 1.5 days in length before the
sequence is repeated. This will provide you with a reliable high security solution for your
voice masking.

Instructions:

The SMG105 is designed to be a “stick-on” type module. It can be mounted either on or
next to your amplifier. Just hook-up the output signal from the SMG105 to the input of
your amplifier, then adjust the sound level using the controls on the front of the unit.
