FITTING FOURIER ® OPTION
Important Note: These instructions provide guidance for installing the Fourier interface card in the Q7 console. This technical note is intended solely for use by factory‑approved technicians.
Preparations
Read the instructions carefully before starting, and leave yourself time to perform the work.
Ensure you have taken appropriate anti-static precautions
Avoid working in areas with synthetic floor coverings or carpet, especially polypropylene material, as opposed to natural materials such as solid wood or wool. Ideally work at a proper workbench with ESD safe features, such as a metal frame. Before work, try to discharge yourself into a mains earth fitment, water pipe etc.
This is important as parts of the equipment are static sensitive and even if any damage is not immediately obvious, so called “latent damage” can occur, where a device may be partially degraded yet continue to perform its intended function. However, the operating life of the device may be reduced dramatically, leading to premature failure.
If you are unsure about any part of the procedure, seek advice before proceeding.
You will need to have the following tools to hand:
- Pozi screwdriver PZ0
- Pozi screwdriver PZ1
- 5.5mm Socket driver for M3 Nuts
- 35mm hex socket
You should also have:
- A Fourier transform.engine or another Dante audio device for post installation testing.
Before you start, shut down the console, switch it off and remove the power leads.
If the console was previously fitted with a Waves card, please consult TN295 to remove it.
Procedure
Removing the Engine
With the SD7 Quantum engine removed from the console release the top holding
screws on each handle.
On the rear of the engine release the two thumb screws.
Position the engine on its side. Separate the upper and lower section. There
should be no need to disconnect any cables at this point.
Unscrew and remove the air guide.
Unscrew and remove first the optocore reinforcement plate and then the optocore PCB from the main audio engine card.
Unscrew and remove the Waves card from the engine chassis.
Fourier Interface Card Installation
Removing the Waves Card
- Remove the Waves card from the chassis.
- Disconnect the following cables:
- Ethernet cable from SKT1
- Power loom from CN7
- LED loom from CN1
- Disconnect the 686-00146 cable from:
- CN3 on the Waves card
- CN25 on the DSP
Preparing and Installing the Fourier Card
Pre-fit the Ethernet cables to the Fourier card before placing it inside the chassis:
- Connect both Primary and Secondary Ethernet cables.
Once the Ethernet cables are in place, connect:
- The front panel Ethernet cable to the Control port
- The LED loom
- The Serial loom
Fit the Fourier card into the chassis:
- Insert it at a slight angle to prevent the Ethernet connectors from catching on the DSP.
- Once in position, secure the card using four (4) screws.
Connect the serial loom from the Fourier card to the DSP CN25.
Fourier Card Mounting Plate Instructions
Remove the optic nuts and plates from the engine front panel.
Fit the Fourier faceplate:
- Position it so that it covers the Optocore loop (if fitted).
- Pass the RJ45 connectors through the opening where the second loop would normally be.
Secure the faceplate to the engine front panel using the provided screws.
Reattach the Optocore nut to the engine.
- For other optic types, follow the manufacturer’s fitting instructions for the faceplate.
- Place Fourier Audio stocker around the status LEDs
Fourier Card Cabling
Connect the Ethernet cables from the Fourier card to the associated RJ45 connectors on the front panel:
- Primary Ethernet
- Control Ethernet
Route the Ethernet cables neatly:
- Follow the existing Ethernet loom from the DSP to the PC card.
- Secure the cables with cable ties along the route.
Once the installation is complete follow the steps backwards to reassemble the engine. One completed, return engine to the console and ensure correct operation.
Reassembling the mixer
Reattach the upper surface section to the console, using the disassembly instructions at the start of this document if needed.
Test the mixer functions
On completion of the work, connect the mixer to power and carry out a functional test to confirm that the display and controls operate correctly before refitting the panels.
After the test, shut down the mixer and switch off the power.
Secure the panel with screws.
Software Setup Notes
To enable the Fourier Card:
1. On main screen click on ‘Options’.
2. Once Options window is open click and select on ‘Console’.
3. Click on ‘Fourier’ to enable.
4. Close and restart the console.
5. On the next boot, verify the Fourier port is enabled on the Audio I/O.
Ensure the card is set to the same sample rate as the console in Dante Controller. This cannot be controlled by the Console application software.
Fourier Interface Card Specifications
• The Fourier Interface Card provides 64 channels in and 64 channels out at 48kHz or 96kHz to the Dante network.
• The card does not feature Sample Rate Conversion so make sure that the console sample rate and the Dante sample rate of the card (set in Dante controller) match or it could end up with distortion/clicking/no audio.
• The Fourier Interface card cannot be used to control socket parameters (phantom power and gain) of DQ Racks or A168D/A164D Racks.
• When fitted to Quantum consoles, the user can Enable Sync to External in Dante controller for the Fourier Interface Card to get it to clock to the console. Alternatively, the console can be set to clock from the Fourier interface card in Setup\Audio Sync. This will result in the console following the Dante network for audio clock.
