STT-1

SAFETY PRECAUTIONS

For your safety and the safety of others, be sure to read and understand all safety and opera-

tional instructions before attempting to use the STT-1. 

WARNING: The STT-1 internal circuit-

ry carries lethal voltages.

 Carefully observe all warnings, precautions, and instructions on the 

STT-1 and as described in the instructions supplied with the unit.

1. WATER, MOISTURE, AND SPILLAGE

Do not attempt to use the STT-1 in, near, or around water or in unusually moist environments, 
such as near a sink or swimming pool. Prevent liquids or any other materials or objects from spill-

ing or falling into the STT-1 unit. 

2. HEAT AND VENTILATION 

Be sure to allow adequate ventilation to STT-1 and avoid using or installing unit in close proxim-
ity to heat sources, such as heaters, stoves, radiators, power amplifiers, spotlights, or other heat-

producing appliances or equipment. 

3. POWER SOURCES AND POWER CORD PROTECTION

The STT-1 Power Supply should be connected to a power source only of the type described in the 
operating instructions or as marked on the Power Supply. Route the power cord so that it is not 
likely to be walked on or pinched by having objects placed on it. Pay particular attention to plugs, 
receptacles, and the point where the AC power cord exits the STT-1.

4. GROUNDING
For your safety, it is extremely important that the grounding pin of the 3-wire power cable (in-
cluded with unit) be inserted into a grounding type 3-pin power outlet. If you are unable to insert 
the plug into an existing outlet, contact an electrician to install a properly grounded 3-pin power 
outlet, preferably that with OFI protection, if available.

5. DAMAGE REQUIRING SERVICE
This unit should be repaired or serviced by qualified personnel whenever:
· The AC power cord has been damaged, or
· A microphone cable has been damaged, or
· Objects have fallen or liquid has spilled into any STT-1 unit, or
· The unit does not function properly or exhibits a marked change in performance, or
· The unit has been abused, dropped, or damaged, or
· The unit has been exposed to rain or moisture

6. SERVICING

Deadly voltages are found inside the STT-1 chassis.

 The user should not attempt to repair or 

service this unit. All servicing and/or repairs should be referred to Millennia Media. 

If, after reading all instructions, precautions, and warnings, you have remaining questions, please 
contact Millennia Media directly before attempting to use your STT-1. Retain this owner’s manual 
as a record of your purchase to aid positive identification in the event of loss.
