Channel Level Controls
The channel level controls adjust the absolute level
of the output of the relevant channel. Each
Channel control value is displayed on the LCD
screen, with values from OFF (0) to MAX (100%). OFF
is zero output, MAX is full output. The output levels
automatically drop to OFF when selecting a mode,
and will always start off at OFF (0%) when selecting a
new mode.
Joining Controls (A+B Mode)
When you first switch your 2B unit on, both the Channel A and Channel B controls are
independent. However If you select the join mode (A+B) then the two controls become
linked, giving you effectively one handed operation.
When you turn the Channel A control up, the Channel B value will also rise, if you turn it
down, the Channel B channel will reduce as well. If you adjust the Channel B control
when the join mode is active, then you can adjust the relative levels of each channel.
To cancel the channel link, simply deselect the mode, turn the 2B unit off, or select the
factory reset option.

Displays
The 2B has 3 display elements, the bright backlight LCD display, giving the user details
of all of the functions of the 2B, from control settings to helpful messages. The backlight
can be switched on and off (see page 14), and the contrast adjusted (see below)
The two blue LEDs on the right hand side of the unit illuminate in proportion to the
intensity of the relevant output.
Adjusting Contrast
To change the contrast of the LCD, turn the unit over, and with a small
insulated screwdriver insert into the hole in the rear of the unit and gently
adjust the screw inside.
Remember when you select a
new mode, you generally have
to turn the outputs on to get
any response from the
channel outputs.
