# STEP 0. Prepare

Reserve the main room. Pull the MacPro out of the cubby and plug in the power. Pull out the multi-sphere array, move it by pushing on the sub. Move it VERY SLOWLY.

Connect the power and network to the MacPro, according to the labels. The 128.32.122.183 address is for Port #1 which is the public wired network. The 10.0.0.1 address is for Port #2 which you can use with a point-to-point connection directly from another computer.

Connect the AUDIO over ethernet cable to the MacPro. The cable is black and is marked with YELLOW tape, it is stored on the rack.

Turn on the computer and select MAC OSX on the rEFI boot screen (otherwise it will boot into Linux by default). The system will automatically login to username "CNMAT", and the password for this user is "cnmatlab".

NOTE: DO NOT ALLOW SOFTWARE UPDATE TO RUN, IT MAY BREAK EVERYTHING!

NOTE: The keyboard might be in Dvorak mode, you can switch it using the input menu at the top right menu bar (look for the "DV" icon).

# STEP 1. Power on.

Turn ON the power at the power conditioner (top rack).

Open Audio Preferences on the MacPro. Verify that THREE devices are present:

- Dodec
- Rbox
- Meyer120

If the Dodec does not appear, reset the power by holding down the "sequence" button for several seconds, then let go. Repeat power reset until ALL THREE devices appear.

NOTE: The MacPro might crash during this initialization. If it does, keep trying.

Next, turn on the ICOS power amps, starting with the 15V supply, then the 12V supply.

Turn on the DODEC, which is via the two Yamaha 6-channel amps (bottom shelf of the rack, power button on the front panel).

Plug in power to the SUB, which is the thick cable with the blue circular socket.

Patch your analog system (8 channels) into the inputs of the top Rimas box.

# STEP 2. Check Audio Device Settings.

Open "Audio Network Preferences".

Verify that Dodec Audio is set to 44100.0 Hz sampling rate and the clock source is "Word Clock".

Verify that Rbox is set to 44100.0 Hz sampling rate and that the clock source is "Word Clock".

Verify that an aggregate device exists called "Multi-Sphere Array" comprising the above three interfaces, and that resampling is OFF for all devices. Verify that the clock source is set to Meyer120.

NOTE: If you can't get resampling to turn off then disable "use" on all the devices and then re-enable.

# STEP 3. Launch

Open MaxMSP. Go to DSP settings and make sure that "Multi-Sphere Array" is the currently selected device.

Open "cnmat.beam-server" patch. An alias is provided on the desktop. Enable AUDIO.

# STEP 4. Shutdown

Quit MaxMSP.

Shutdown the MacPro.

Unplug the power to the SUB, which is the thick cable with the blue circular socket.

Turn off the DODEC, which is via the two Yamaha 6-channel amps (bottom shelf of the rack, power button on the front panel).

Turn off the ICOS, starting with the 5V supply, then the 15V supply, then the 12V supply.

Turn off the equipment rack using the power strip located on the lower left side.

Disconnect the network and power from the MacPro.

Disconnect the AUDIO network from the MacPro.

Put the MacPro back into the cubby.

Push the Multi-sphere Array back against the wall; push on the sub to move it, and move slowly.
