FRONT PANEL FUNCTIONS
Buttons: Up / Down toggle buttons for display selection during normal operation and
setting selection in setup mode.
Press this button to enter setup mode and press it repeatedly to scroll through
all setup menu items. This mode is automatically exited when no button is
pressed for at least 10 seconds.
Some setup menu items can be changed with the Up / Down buttons on the
front panel. See setup menu chapter for more information.
Mute toggle on / off.
Standby power on / off: Press this button when the amplifier is in standby mode
to switch on the amplifier or when it is running to shut it down again.
The AC Power switch on the back panel must be in “on” position. During the
power-on and power-off sequence the amplifier goes through a special
sequence of internal checks. This takes a while and is indicated on the front
panel.
Between each power-off and power-on sequence there is a 10 second delay
i.e. you have to wait at least 10 seconds before the unit can be turned on again
after powering off.
NOTE: In order to power off the SPA-8 it is important to always first use the button on the front panel to set
the amplifier into standby mode and let it discharge its internal circuits.
Do not turn power off with the rear
panel switch during normal operation or before the amplifier has not finished its internal power-down
sequence and the front panel display is turned off signaling standby mode!
