Operation
Front panel layout
1) Power switch: power on the unit by flipping the switch to the ‘on’ position. In the ‘OFF’ position,
ALL electrical circuits are disabled. In the ‘on’ position, the unit can be switched to standby
using an RS232 instruction, which will turn off the main power supply, resulting in very low
standby power consumption.
2) Sub mute/select switch: during normal operation, push once to mute the sub channel. During
parameter editing, this button can be used to select the sub channel. In editing mode, you
can also push multiple channel switches at once to edit the parameters simultaneously for all
channels.
3) Left channel mute/select switch: during normal operation, push once to mute the left channel.
During parameter editing, this button can be used to select the left channel. Some parameters
are linked for left and right channels.
4) Right channel mute/select switch: during normal operation, push once to mute the right
channel. During parameter editing, this button can be used to select the left channel. Some
parameters are linked for left and right channels.
5) Dot matrix LCD display with blue background light. The standard text displayed on the normal
screen can be edited using RS232 commands. The display shows the actual master level. On
the right, arrow symbols appear. These are located next to the three push buttons used for
parameter editing. The symbols may change to text, related to the function of the push buttons.
6) Menu buttons. During normal operation, the uppermost button is used to enter (return to)
the main menu, the middle and lower buttons are used for scrolling through the available
parameters appearing in the display. An editable parameter will be highlighted in the display,
and the value can be changed by turning the rotary encoder. The function of the push buttons
will change when necessary. The function of the push buttons is described on the right side of
the LCD dot matrix display.
