POWERING UP
1. Make sure that one (or more) loudspeaker cabinet(s) are connected to the SPEAKER OUT socket, that it (they) has (have)
an adequate power handling capability and is (are) suitable for guitar signals. Check that the impedance selector switch
on the device corresponds with the total load impedance of the connected speaker(s).
2. Make sure that the device is plugged in to the mains and that any external (effects) devices are correctly connected and
operation ready.
3. Turn the MASTER control all the way to the left.
4. Connect your guitar to the INPUT of the amplifier using a screened cable.
5. Turn the device on using the POWER switch.
6. When the valve (tube) warm-up phase is complete, turn the STANDBY switch on (upwards).
7. To obtain the desired sound for each channel, select the channel and adjust the controls.
To familiarize yourself with the basic sound of the amplifier, set all the rotary controls to 12 o'clock (straight-up).
CONCLUDING ADVICE
- This amplifier is capable of generating high volume levels that can cause hearing damage
- At high GAIN settings, feedback between the guitar and the speakers may occur and this can cause hearing damage as
well as damage to connected loudspeakers.
- Unplug the power cord whenever changing a fuse!
- Only ever replace a fuse with another of the same type. Never bridge defective fuses.
- Valves can become very hot.
- Don't undertake repairs yourself.
- Only allow the case to be opened by qualified personnel.
- Qualified personnel should do any repairs and valve changes.
- Never use floor pedal effect devices through the effects loop, as such devices have the wrong connection values.
