Amber i4 – Release Notes 2.x

New firmware, new user interface and new driver

New Firmware 2.x

Each headphone output (HP) can be fed separately with its own mix. This expands the Amber i4 into an 8-channel interface.

Hardware inputs 1–4 as before:
- Inputs 1 and 2: Line / Hi-Z / Mic
- Inputs 3 and 4: Line
Inputs 5 and 6 are loopback channels. They optionally route back Line Out A, Line Out B, HP 1 or HP 2 for recording.

The graphical user interface reflects the new firmware and has been extended with playback channels 5/6 and 7/8.

Individual mixes: For each output pair (Line Out A, Line Out B, HP 1, HP 2), a separate mix can be created from all playback channels and all analog inputs.
Linking output pairs: Output pairs can be linked by holding the Alt key (Windows) or ⌥ Option key (macOS).
Mini mixers: The sliders can be adjusted directly in the mini mixers.
Level meters: Every signal has its own level meter.
Snapshots: The number of snapshots has been increased to 16 (accessible via scroll bar).
Loopback: The loopback can take its signal from any of the four output pairs, either via the drop-down menu on the left or via the checkbox in each output pair.
Monitoring: Mono/stereo monitoring has been significantly improved.
Mono summing: Playback channel pairs can be summed to mono. The balance controls then become panning controls.
