Sound Card

24 bit sound card with high quality audio output which offers multiple analogue and digital interfaces
GUS officially stands for "Great Unbelievable Sound", but can also be read as a reference to the Gravis Ultrasound (GUS) sound cards of the 1990s with superior sound quality
32 MB on-board sample memory, clocked at 122.2 MHz
high-quality digital mixer which operates at full 192kHz @ 24 bit resolution
32 channel wavetable engine - featuring per voice:

8 /16 bit sample support, 192kHz @ 24 bit mixing rate
sample start, stop and loop pointer for effective one-shot or continuous playback modes
32 bit sample phase accumulators allows fine grained pitch definition
optional sample interpolation for smooth sounds
channel independent left / right stereo panning
hardware ADSR envelope generator

MP3/OGG/FLAC/WMA hardware decoder (VLSI VS1063), enhanced by a DMA stream buffer
inputs/outputs:

1× RCA stereo output, converted from 192kHz @ 24 bit
1× TOSLINK optical digital output, supporting 48kHz, 96kHz & 192kHz @ 24 bit
3× analogue audio inputs, sampled at 192kHz @ 24 bit: Paula (internal header), CD-ROM (internal header), external source (external RCA input)
1× digital output of final mix, to be used as input for other cards

AHI stream interface, supporting 8 /16 & 24 bit modes for playback and recording
mixer settings are stored in flash and automatically loaded on start-up - thus working without additional software
upgradable FPGA core via JTAG interface, or via Amiga-based flash tool
open hardware, gerbers and FPGA bitstream are freely available on Github
as the card does most of the tasks in hardware, the minimum system configuration is an A2000 with stock 68000 CPU @ 7.09 MHz, 1 MB ChipRAM and 4 MB FastRAM
driver support: AHI, MHI, CAMD (planned)

Interface

RGB port

DVI Converter

converts the analogue RGB video and audio signal of the Amiga into a digital DVI signal
very low latency < 20 ms at 50 Hz (one frame)
scanlines can be displayed to emulate a CRT display, dimmable in 16 levels
supported Amiga video formats:

Lores (320 pixels per line), Hires (640 pixels per line)
interlace and progressive modes
PAL and NTSC
Overscan up to 672×520 at 24 bit color depth, or up to 800×600 at 16 bit color depth (firmware ≥ v1.2 only)

small box that plugs directly into the DB23 RGB port
1× 3.5mm stereo audio input, to be connected to the L+R audio ports of the Amiga
1× HDMI port
control knob on the front panel to set up scanline intensity, video mode, pixel sampling (samples, phase) and x/y position, or perform a reset
two LEDs in the control knob indicate the current mode through color and blinking pattern
on-screen display (OSD) shows current setting on the monitor
firmware update is done through a bootable floppy disk (DF0: only) which displays an image sequence on the RGB port
firmware revision v1.2 provides a 'panic mode' which returns to a default video mode, and improved overscan support through selectable color space
power supply through the Amiga
expansion is incompatible with the CDTV
can be used on the CD32 only with an RGB expansion, due to the lack of an RGB connector at the base model
