update the internal software (firmware) of your 
TC bass amp.

13. 

UTIL button

TC may provide updates for the built-in software 
of your amplifier, the firmware. Updating your TC 
amp’s firmware requires…

►

a computer running Microsoft Windows or 
OS X with a standard USB interface

►

a USB cable.

Preparing the firmware update

Download the newest firmware from the “Sup-
port” page for your TC amp. If a firmware update 
is available, you will find updaters…

►

for Microsoft Windows (these are ZIP ar-
chives containing the firmware installer) and

►

for OS X (these are disk image files containing 
the firmware installer).

►

Connect your TC amp to your computer using 
a USB cable.

►

Power up the amplifier while pressing and 
holding the UTIL button on the rear panel.

►

After a few seconds, you should see the LED 
next to the UTIL button turn red.

►

Launch the firmware updater you have down-
loaded and follow the on-screen instructions 
to apply the firmware update.

14. 

AUX IN Rehearsal input

The AUX IN is a stereo 1/8” auxiliary input. Any 
signal present on the AUX IN jack is played back 
through the output of your bass amp. This allows 
you to play along with a rehearsal track, or you 
can practice to the beat of a metronome click. 
The included “mini jack to mini jack cable” allows 
you to use a smartphone or any other consumer 
playback device as a source for rehearsing.

15. 

PHONES (Speaker Mute) jack

The PHONES jack is a 1/8” connector for head-
phones. With a mild speaker filter applied to the 
bass sound, our studio quality headphone amp 
caters for a great headphone sound.

The headphone output also plays back any sig-
nal connected to the AUX IN input jack.

AUX IN and PHONES jacks are the perfect com-
bination for rehearsing or checking out new 
tracks without disturbing the neighbors.

16. 

PRE/POST EQ switch

Use the PRE/POST switch located to the left side 
of the BALANCED OUT jack to determine where 
in the signal chain the signal for the balanced 
output should be tapped.

►

POST setting (top): The signal is tapped 

after

the EQ section and the currently active Tone-
Print effect, allowing you to use the signal 
with the specific flavor of the amp.

►

PRE setting (bottom): The signal is tapped 

before

 the EQ section and the currently active 

TonePrint effect. Use this setting if you want 
to record your bass sound without any effects 
or equalization applied.

17. 

BALANCED OUTPUT

Use the BALANCED OUT XLR jack to connect 
your bass amp to the PA when you play on stage, 
or to connect your amp to a recording device 
when you are in the studio.
