Getting Started
- Read and understand the included “Important Safety Instructions.”
- Make sure the Power and Standby switches are off before making any connections.
- 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.
- 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.
- With the Gain and Master/Volume controls fully off, turn the Power switch on. The Power LED will illuminate. Wait 30 seconds.
- Turn the Standby switch on.
- While playing the instrument, adjust the Gain and Master/Volume knobs to the preferred level.
- Adjust the EQ knobs and switches to taste.
