20. Voltage Select Switch
Set the correct mains input voltage to match your current location before connecting
to a power outlet. Loosely unscrew the hook side of the clear plastic switch cover to
rotate it and access the switch if necessary – do not fully remove the plastic switch
cover access screws.
WARNING:
Never change the voltage selection whilst the amplifier is switched on.
Failure to ensure the correct voltage selection will cause damage to your amplifier
and serious risk of injury.
21. Speaker Output
Connect your amplifier to a passive speaker cabinet here. This speakON combo
jack allows for either speakON or 1/4" speaker cable operation. The minimum total
rated impedance of this amplifier is 2.67 Ohms; for higher impedances the maximum
output power is reduced.
WARNING:
Always ensure the total connected impedance is 2.67 Ohms or greater.
Failure to do so could result in damage to the amplifier.

22. Footswitch
Connect the included FS-13 2-way footswitch or the optional FS-12 5-way
footcontroller here using a standard mono ¼" instrument or speaker cable. See the
Footcontrollers section on page 15 for more detail on the operation and functionality
of compatible footcontrollers.

14. Compressor Level
Controls the overall amount of compression by adjusting the threshold, attack,
release and make-up gain simultaneously. Lower settings of the control result in
slower attack and release times and a higher threshold. Increasing the control will
lower the compression threshold and increase the make-up gain, and make the
attack and release times quicker accordingly.
15. Compressor Select
Switch the Compressor on and off. The optional FS-12 5-way footcontroller can
be used to switch the Compressor on and off when used in conjunction with the
included FS-13 2-way footswitch. See the Footcontrollers section on page 16 for
more detail.
16. Master Volume
This controls the overall output volume of your amplifier. Turning it clockwise
increases the volume. Setting the Master Volume to zero allows for silent practice
or recording via one of the Line Output connections on the rear panel.
The level of the Cabinet Link XLR output on the rear panel is also controlled by the
Master Volume.
17. Power Indicator
The Power Indicator will be illuminated when the amplifier is switched on.
This is a multi-function LED which is also able to indicate a fault state within your
amplifier by flashing on and off. Your Unity Elite amplifier is equipped with several
protection features designed to prevent damage if the normal operating limits are
exceeded. If the amplifier detects it is getting too hot it will enter a protection mode
and the sound output will be muted; this protection mode will be indicated by the
Power Indicator flashing on and off. Once your amplifier cools down sufficiently the
sound will automatically unmute and the Power Indicator will return to constantly ON.
If the Power Indicator continuously flashes on and off a different fault could be
present. In this event please contact your point of purchase, local distributor or
Blackstar directly for servicing instructions.

18. Power Switch
This switch is used to turn the amplifier on and off.
19. Mains Input
The supplied detachable mains power cable is connected here. Always ensure the
Power Switch (18) is in the OFF position and the Voltage Select Switch (20) is showing
the correct voltage for your location before applying mains power. The cable should
only be connected to a power outlet that is compatible with the voltage, power and
frequency requirements stated on the rear panel. Never break off the earth (ground)
pin on the mains cable. If in doubt seek advice from a qualified technician.
