1. SAFETY PRECAUTIONS Be sure to read the instructions in this section carefully before use. Make sure to observe the instructions in this manual as the conventions of safety symbols and messages regarded as very important precautions are included. We also recommend you keep this instruction manual handy for future reference.
SAFETY PRECAUTIONS When the Unit is in Use When Installing the Unit Do not place heavy objects on the unit as this may cause it to fall or break which may result in personal injury and/or property damage. In addition, the object itself may fall off and cause injury and/or damage. Never plug in nor remove the power supply plug with wet hands, as doing so may cause electric shock. When unplugging the power supply cord, be sure to grasp the power supply plug; never pull on the cord itself.
2. FEATURES 1. Rated Power:60W/120W. 2. 100V,70V constant voltage outputs and 4~16 Ohms constant resistance output. 3. Commercial-grade torroidal transformers produce high performance audio on a wide range of frequencies with min noise and high fidelity, even at high volume. 4. Reliable protection against overload, short ciruit, and power fluctuation for optimum reliability. 5. VOX feature mutes AUX inputs when input is detected on MIC 1.

5. MACHINE OPERATION OPERATION ATTENTION MUTE FUNCTION The four output connectors only can choose two connectors work together. If voltage is 70V/100V, the speakers must be with transformer and make sure the total power wattage of speaker is 15% less than the power wattage of amplifier. 1 Tel has priority over all inputs. 2 MIC 1 is second priority, adjust mute electric potential can override other input signal except tel signal.
