Safety Instructions

• Earthing: This apparatus MUST be earthed. Under no circumstances should the mains earth be disconnected from the mains lead.
• Changing the Fuse: Replace only with the same value and type of fuse as marked on the unit, 500mA T (230V) or 1000mA T (115V). Always switch off the unit and remove the AC power cable before changing the fuse.
• General Safety: Do not place the apparatus on an unstable surface, insert objects through any apertures, use near water, or block ventilation openings. Install in accordance with the manufacturer’s instructions and avoid placing near heat sources.
• Power Cord: Protect the power cord from being walked on or pinched, particularly at plugs and where they exit from the apparatus.
• Mains Cable: The supplied IEC mains cable must be terminated correctly to the AC mains supply before use. Use only an approved AC plug or power distribution device.
• Voltage Operation: Before adjusting the operating voltage, always switch off the unit and remove the AC power cable. Use a flat blade screwdriver to click the voltage selector to the required position until the legend 115V or 230V appears in the window and fit the appropriate fuse supplied in the fixings pack.

Cleaning and Maintenance

• Cleaning: The product should be cleaned with a soft brush around the controls. If the facia becomes dirty, use a damp cloth with a little household soap to remove the dirt. DO NOT use solvent cleaners.
• Rack Mounting: This product is designed to be rack-mounted using the supplied screws and washers to help preserve the finish of the facia panel. Additional rack mount side supports are recommended for vibration and transit shocks.
• Audio Connections: Two 3-pin XLR connectors are provided on the back side. Inputs are female, outputs are male. All connectors follow the European wiring convention: Pin 1 = Screen, Pin 2 = Hot (+), Pin 3 = Cold (-). Jack input for instrument in front side.
