22. Cabinet Link
Extend your setup by connecting a Blackstar Unity Pro Bass U250ACT Active
Cabinet (sold separately) to the Cabinet Link output using an XLR cable. Multiple
U250ACT Active Cabinets can be linked together to create a near-limitless power,
modular setup, where each U250ACT adds up to 250W of additional power through
a custom-designed 15" Eminence speaker.
The Cabinet Link output level is controlled by the Master Volume (12).

14. Power Switch
This switch is used to turn the amplifier on and off.
15. Mains Input
The supplied detachable mains power cable is connected here. Always ensure the
Power Switch (14) is in the OFF position 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 get advice from a qualified technician.
16. Footswitch
Connect any 2-button latching footswitch (e.g. Blackstar FS-8, sold separately)
here. The ‘Tip’ connection (usually the left-hand button) will switch between the
currently active Voice (5) and the Overdrive Voice. The ‘Ring’ connection (usually the
right-hand button) will toggle the Chorus effect ON and OFF.
17. MP3 / Line In
Play audio from any device with a 3.5mm output (e.g. your phone, MP3 player, tablet,
laptop etc.) through your Unity Bass amplifier using a 3.5mm (1/8") AUX cable (sold
separately). Adjust the volume on your playback device to match that of your bass
guitar to enable you to play along. The volume to the internal speaker is controlled by
the Master Volume knob (12). The MP3 / Line In signal is also mixed to the ¼" Line
Out (18) and XLR Line Out (20).
18. ¼
"
Line Out
This is a dual-mono ¼" output for direct recording or connecting your headphones
for monitoring and ‛silent’ practice. The output level is defined by the position of
the Line Out Level knob (19). Set the Master Volume knob (12) to zero for ‛silent’
practice.
19. Line Out Level
This is a separate volume control for the ¼" Line Out (18) and XLR Line Out (20),
used to set a suitable output level for recording or monitoring via headphones. This
control has no effect on the internal speaker volume.
20. XLR Line Out
This is a balanced output for connection to a PA, mixing desk or interface for
recording and monitoring. Using a good quality screened cable, the balanced XLR
connection provides a high quality signal, free of noise. The output level is defined
by the position of the Line Out Level knob (19).
NOTE:
Your Unity Bass amplifier will NOT be damaged by applying Phantom power
to the XLR Line Out, and will have no effect on the operation of the amplifier
21. Ground Lift
This switch can be used to remove the circuit-to-chassis ground connection of the
XLR Line Out (20), which can help if experiencing hum or noise upon connecting to
an external device. If you do experience a hum engage the Ground Lift by depressing
the button to lift the ground on the circuit.
