Hardware Installation
1. Remove the protective tape from the steel slot bracket. Use a cloth to wipe away
any residue from the bracket.
2. Mount the slot bracket to ZZ9000AX with 2×
supplied M2 screws and nuts. The nuts go on
the bottom side as pictured.
3. Connect ZZ9000AX to ZZ9000 using the Data and Internal Audio Cables as
described in the "Hardware Installation: Cables" section of this manual.
4. Mount ZZ9000AX above ZZ9000 in your Amiga 2000/3000/4000.
Software Installation
1. Install the AHI system version 4.18. We recommend not to use AHI version 6, as it
has significantly higher CPU usage and can cause audio stuttering.
• AHI on Aminet: http://aminet.net/package/driver/audio/ahiusr_4.18
2. Download and install the ZZ9000AX drivers that are included in the ZZ9000 driver
package. Power cycle your Amiga. Then, configure ZZ9000AX in AHI Preferences.

SigmaDSP
The audio chip on ZZ9000AX—Analog Devices ADAU1701—features a 28-/56-bit, 50
MIPS SigmaDSP (digital audio processor). The DSP program determines the signal
flow to and from ZZ9000AX, including digital mixing and optional effects. The default
program (which mixes AHI and Amiga Paula sound) is included in the ZZ9000
firmware, but can be changed with the free SigmaStudio software from Analog
Devices and an upcoming tool from MNT Research. Visit the ZZ9000 website for
tools and updates.

Jumpers and Headers
ZZ9000AX has two IN/OUT headers
that you can use to set the direction
of the two auxiliary audio channels.
When the jumpers are in the IN
position, you can input or sample
stereo audio through these channels.
In the OUT position, the channels can
be used as additional outputs.
Please note that if you change the
jumpers, you also need to set up the
DSP program accordingly. By default,
the DSP program is configured for
audio input on the auxiliary channels.
