Viola Laboratories Spirito Reference Series Preamplifier Owner's manual

1.6.1 Power Indicator Light

• The ring around the power button is an LED that shows the operational

status of your preamplifier:

• Completely off indicates that the amplifier is not connected to the AC

Mains. Note: If the amplifier will not turn on, you should check your AC

connections and inspect the fuses.

• Green indicates that the Spirito is on and ready to be used.

• Amber indicates that the Spirito is in standby mode. The display backlight

turns off and the outputs are muted.

• Red indicates high AC line voltage or over temperature. Check that the

AC voltage on the supply is set to the proper voltage and that the Spirito

has proper ventilation.

1.6.2 IR Window

• IR communication is full duplex. The Spirito can send and receive data

across the IR. The Palm OS program that comes with the Spirito is used to

turn a Palm OS device into a remote control and also to update the Palm

when you add more modules.

1.6.3 Display and touch screen

• The Spirito incorporates a touch screen for various functions. Soft keys are

used for the onscreen controls. This allows for new onscreen controls when future

modules are added.

1.6.4 Volume Control

• The Spirito volume control is used for several functions depending on the

mode of operation. It is used for main volume, setting the channel volume

offsets and to scroll through the ASCII character set for board and channel

names.

1.6.5 Balance Control

• The Spirito balance control functions, if enabled through the V30 output

screen, as a true pan pot type balance control. The balance control will

shift the image to the right or left with no increase in volume. The balance

control also is used to advance the cursor when renaming board or channel

names.
