Owner’s Manual for AMT Pangaea Ultima U-2
Firmware «07 - BassMix FX» 2

DEAR FRIEND!
Thank you for purchasing (or continue of using) the AMT Pangaea Ultima U-2
device!
This device is not just a pedal. In your hands is a powerful hardware
platform on the basis of which various guitar/bass effects & many other
functionalities can be implemented due to software (via different firmware).
The Ultima U-2 is a part of the great «AMT BRICKS» series of devices, which
includes different preamps, effect pedals, noise suppressors, IR cabinet
simulators, device controllers, pedalboards, etc. All this gear has a common
design concept «mini sneakers’ size» and functional compatibility (including
via special BRICKS CONNECTOR on the underside of each device). Almost all
of BRICKS devices can be used both independently and being joint together.
This document is the Manual for the Firmware «07 - BassMix FX»,
which was developed by AMT engineers especially under bass player
requirements who would like to diversify the sound of their instrument
with many interesting features and great built-in AMT Ultima U-2 FX
effects.
The Firmware «07 - BassMix FX» includes many features that make the
Ultima U-2 capabilities to a new level of usability by bass players and make
the device unique among competitors:
- Full stereo input: two independent input channels IN L (MONO) and IN R;
- Special option controlling the mixing of both input signals;
- Two independent main output balanced channels OUT L and OUT R;
-OUT R output has the global configuration option that allows it to work or
as a «Full Mix» output with all preset’ effects, or as «Dry L+R» mix of both
input channels signals without any IR and effects;
- Stereo AUX IN and Headphones PHONES stereo output;
- Ability to connect up to 2 external two-buttons footswitches, expression
pedal or external MIDI controller via special ports MIDI IN/F.SW-A and
EXP/F.SW-B;
- Special mode of working and controlling with two external AMT Bricks
preamps connected via mini TRS cables (mini stereo jack);
- Totally programmable built-in footswitch with two-actions options: short
or long pushing.
EFFECT SECTIONS
- [NG]: Easily customizable Noise Gate (global settings for the entire device
as well as individual setting up for each preset);
- Powerful [WH] Wah-Wah section: use it as an Auto-Wah effect or connect
an external expression pedal to the Ultima U-2 and have the full-range Wah-
Wah control by your foot;
- [CM]: Compressor (Pre/Post mode);
- [FX]: Phaser / Chorus (you can choose the effect you would like to use at
the moment in each preset);
- [IR]: Cab sim section based on IR player with a WAV browser of guitar/bass
cabinet impulse responses (with the mixing level option between the signal
processed by IR and the DRY sound signal);
- [EQ]: Multiband highly quality graphical Parametric EQ;
- [FT]: High pass & Low pass filters with a Presence effect;
- [FX]: Multi-type Delay (with connectable Early Reflection’s settings if
needed) / Reverb (you can choose the effect you would like to use at the
moment in each preset) with a controllable option to enable/disable «tails»;
- Tuner (double short push on the ENCODER);
- Metronome (long single push on the ENCODER >> Metronome).

Firmware «07 - BassMix FX» 4

The main feature of the Firmware «07 - BassMix FX» is the possibility to
connect to Ultima U-2 up to two different external preamps (with an already
activated preamp channel on each of them). The Ultima device gives you
full access to mixing both signals goes from IN R (21) and IN L (MONO) (23)
inputs.
You can easily mix two input signals simultaneously as you wish. There is a
special parameter IN Mix inside of each preset’s menu. Settings
L 063/063 R of this parameter allow you to control by the
ENCODER (7) a value of cross mixing of signals. Check these some visual
diagrams as an example for more deeply understanding how the sound
mixing is going inside of the Ultima U-2:

Firmware «07 - BassMix FX» 6

For the firmware starting from version v.1.01.02, it is possible to place the
[CM] Compressor effect in different positions of the virtual preset effects
chain by using Pre/Post modes.
Pre mode
When using this mode, the Compressor is located in the virtual chain after
the wah-wah effect [WH] before [FX] (Phaser / Chorus):
Post mode
In this case the Compressor will be placed after the Low&High Pass filters
[FT] before [FX] (DL/RV):
Important note: on the main Ultima’s display screen (where the preset
name and number are displayed), the visual sequence of the effects icons
is always the same:
At the same time, in the preset menu window there is an indication which
mode (Pre or Post) the Compressor is currently operating in:
