- Page 5 The main menu has the following functions: CLOCK Here you can set the A32 to generate the wordclock itself (master) or listen to a wordclock signal (slave) from an external source. If choosing Master you can also select the sample rate here.
- Page 6 Operation PRESET Levels, gains and the routing of the A32 can be saved and loaded in up to six different preset slots. HELP You can change the language of the help system here, get information about the schematic structure and lookup the firmware version of the...
- Page 7 MADI, ADAT If you set the clock source to MADI or ADAT, the A32 extracts the wordclock signal from these digital inputs, reduces jitter using the digital PLL circuit and routes it back to the BNC output. The A32 then uses this clock signal.
- Page 8 Operation SMUX operation Internally the A32 always uses all 32 analog channels, but the number of digital MADI and ADAT channels is limited in relation to the SMUX mode currently in use. SMUX/1 SMUX/1 offers frequencies from 32kHz up to 48kHz.
- Page 9 Operation main menu – MIX Inside the MIX menu you can select one of seven mix presets. The A32 allows you to create a custom mix of all analog and digital I/O’s which can then be sent to the stereo headphones output on the front panel.
- Page 10 Operation main menu – DIGITAL The DIGITAL menu shows all analog and digital inputs and outputs. All digital inputs and outputs are shown as dots with a traffic light color code. In this way, you have an overview of all channels at a glance. The traffic light LED colors have the following meaning: Color Range...
- Page 11 Operation main menu – SETUP -> GAINS The analog inputs of the A32 can be set to different sensitivities. You can choose between three reference levels: +4dBu, +13dBu and +20dBu. Using the DSP, you can additionally set the reference levels from -8dBu to +20dBu in 1 dB steps.
- Page 12 As with the inputs, you can set the level of each channel in 1dB steps from -8dBu to +20dBu. The A32 offers individual analog level switching of +4dBu, +13dBu and +20dBu. This means that this level is reached when the digital output reaches 0dBFS.
- Page 13 Operation main menu – SETUP -> ROUTING The A32 features a sophisticated routing matrix. In the ROUTING screen you can see a graphical representation on the left side and a list view on the right screen. To change the routing, do the following: ...
- Page 14 Operation main menu – SETUP -> MADI The A32 has two MADI formats (one optical and one coaxial) which can be used in a very flexible way: 1 - optical The A32 only uses the optical MADI input. No automatic switching between the formats will happen.
- Page 15 The MIDI routing screen is intended to allow you to choose the way MIDI data is routed between MIDI and MIDI over MADI: 1 - separate MIDI-over-MADI and MIDI are separated. Control messages for the A32 are scanned from both input ports and replies are sent back to the corresponding output port.
- Page 16 In the SETTINGS screen you can switch some global features: BNC Termination The wordclock of the A32 is terminated internally with a 75-ohm resistor by default. When daisy chaining wordclock of several units, you should leave this option set to ON. If you’re using T-connectors for the connections set this option to OFF, because in this case only the last unit in the chain should be terminated.
- Page 17 When using two power supplies for redundancy reasons, please set this menu option to ON. If switched on, the A32 monitors both PSU inputs. In case of a failure of one power supply, the A32 will display a warning message on the main screen.
- Page 18 To unlock the A32, repeat the procedure: Enter the correct number and hold down the MENU button for a few seconds. The PIN number of each A32 is fixed and can’t be changed by the user. IMPORTANT: Keep the PIN code in a safe place! Reconstruction of a PIN code by the manufacturer is subject to a fee.
- Page 19 Operation main menu – DSP The Sharc DSP built into the A32 is used for routing, mixing and gain/level settings. But the DSP can do much more audio processing: Using the USB connection, you can install Ferrofish-DSP plugins, which are able to process audio effects with high accuracy and without latency.
- Page 20 – PRESET The A32’s GAINS, LEVELS and the routing can be permanently stored in one of six preset slots. This lets you pre configure the A32 and saves you time later by just recalling the presets. The PRESET Menu lets you choose which preset to load:...

- Page 22 D-Sub25 connectors are used for the analog inputs and outputs. The pin configuration corresponds to the TASCAM® standard. When connecting an unbalanced device to the A32’s input, please connect the inverting (cold) input channel to ground. When connecting an unbalanced device to the A32’s output, please...
- Page 23 This way you can connect two units to transfer 64 analog inputs and 64 outputs. The A32 has an optical and a coaxial MADI port. Both ports can be used simultaneously for redundancy purposes. When using the SMUX/4 mode, each port transfers only 16 channels, so both ports will be used to transfer all 32 analog channels.
- Page 24 In this case the first 16 channels are transferred using the optical port and the remaining 16 channels via the coax port. The A32 detects automatically if 64 or 56 channels are received. The number of channels it outputs can be set by using the MADI short...
- Page 25 64kHz, 88.2kHz, 96kHz (SMUX/2) 4 channels x 4 I/O The A32 has four ADAT pairs, capable of transferring 32 channels in SMUX/1 mode. The ports with the white door are the ADAT outputs, the ports with the black door are the inputs.
- Page 26 The A32 can generate its own clock or it can synchronize to an external clock. For external synchronization the A32 can use the wordclock embedded in the MADI or ADAT data stream.
- Page 27 The USB port can be used to remote control the A32. When connecting to the PC, the A32 will appear as a USB-MIDI device. Also, USB will be used to flash new firmware to the A32. Please visit our website to check for a new firmware version.
