Front Panel controls
Navigation
To navigate around the menu systems, use the cursor keys and OK button. To move up
and down to menu items use the UP and DOWN cursor keys. To change a selection with-
in a menu option use the LEFT or RIGHT cursor keys
Note that changes are not actioned until OK is pressed. At this point the unit will go
through a MUTE cycle while the settings are configured.
Input 1, 2 and 3
These buttons select which input connections are used on the back panel. Input 3 is only
functional when the balanced input module (option) is fitted
Low Filter
The Low filter may be used to remove low frequency 'warp' and 'rumble' signals. The filter
operates at 15Hz and should not degrade the normal audio signal in any way.
We recommend that the Low filter is used at all times to ensure maximum protection from
loudspeaker cone over excursion.
High Filter
The high filter may be used to remove hiss or reduce the level of clicks on poor quality or
damaged discs.
The filter operates at 15kHz and will therefore cause minimal degradation to the normal
audio signal.
Mono
Mono combines the cartridge signals to produce a mono signal. This is useful when a
mono recording is replayed. In this mode, any surface noise and clicks are also produced
in mono and are therefore less objectionable. If mono is not used, mono recordings will
be replayed with 'stereo' noise which can be annoying.
Mute
Mute silences the output. This is useful when cleaning the stylus or when changing arms
or headshells etc.
