Switching On
Select an operating mode (Triode or Ultra Linear)
Select the Negative Feedback level (Min or Max)
Select a pair of loudspeakers (A or B)
Turn the volume control fully anticlockwise to its minimum setting (0).
Switch the ON/OFF switch to “I” to switch the amplifier ON.
The power Indicator will light up.
Warming Up
Allow at least fifteen minutes for the amplifier to 'warm up' before use. Warming up should
always be done with the amplifier volume control at zero. After the amplifier has warmed
up fully, the system is ready for use.
Selecting an input
Move the Input selector to the left or the right to select the phono or a regular line input.
The input indicator indicates the selected input.
Remember to turn the main system volume control to minimum when changing inputs or
when changing discs, and especially when cleaning your stylus.
Changing Loudspeakers
Turn the volume control to minimum and then switch the Speaker Selector from A to B or
vice versa to change loudspeakers. Turning the volume down is very important if you are
changing the output from a low sensitivity loudspeaker to one of high sensitivity.
Changing the Mode and Negative Feedback (NFB) Settings
Turn the Volume control to minimum, switch the amplifier off and wait a few seconds. Now
you may change either or both settings and switch power on again.
For a full technical explanation of these settings please refer to Page 10
Altering the volume
Turn the volume control up to a moderate level. Remember the position of the volume
control is NOT an indication of “how loud” your system will play.
DO NOT switch the operating mode or alter the NFB settings when the amplifier is
switched on
