Getting Started

1. Read and understand the included “Important Safety Instructions.”
2. Make sure the Power and Standby switches are off before making any connections.
3. Push the line cord securely into the amplifier’s IEC connector and plug the other end into a grounded AC outlet. The amplifier may accept the appropriate voltage as indicated near the IEC connector.
4. Connect an instrument to the amplifier’s Input jack with a (shielded) 1/4” instrument cable. Connect speaker cables to speaker cabinets with (non-shielded) speaker cable with Speakon or 1/4″ TS ends.
5. With the Gain and Master/Volume controls fully off, turn the Power switch on. The Power LED will illuminate. Wait 30 seconds.
6. Turn the Standby switch on.
7. While playing the instrument, adjust the Gain and Master/Volume knobs to the preferred level.
8. Adjust the EQ knobs and switches to taste.
