Phoenix Audio Technologies www.phnxaudio.com 2 Introduction The Phoenix Octopus Conferencing Mixer utilizes Beamforming microphone array technology, provides unlimited daisy chain capability, and allows for multiple connectivity options all in a single, easy to install box.
Product Concept The Octopus is designed for easy installation and setup, therefore the microphones are mixed automatically utilizing a sophisticated Beamforming Mixer algorithm.
Panels Overview Front panel includes: One/Off switch Power LED i ndicator ¼” audio Monitor jack – this jack is used for setting and testing the unit.
Designing & Installing the Octopus System For optimal performance we recommend the following steps while setting up the Octopus system: 1) Making all the necessary connectio ns, including the microphones, speakers, communication interface(s) and controls.
Two layer configuration with 12 matrix microphones and 1 podium microphone Three Slave units and one Master If your setup requires more inputs you need to create additional layers; connect the lower level Salves to mid-level Slaves (Link Up to Mic input) and so on.
Three layer configuration with 20 matrix microphones, 1 podium microphone and 1 auxiliary input (tape) Five Slave units and three Masters In1 In2 In3 In4 Link Up In1 In2 In3 In4 Link Up In1 In2 In3 In.
Speakers The loudspeaker signal can come from different communication sources. It could come from the far-end of the IP link (through the USB communication), through the far-end of the telephone line (digital or analog), it could come from the far-end of the Video Codec system (through its speakers’ RCA jack), or any combination of the above.
If the speaker source is not sole ly VC it is req uired that the room speakers be fed through the Octopus. The USB and telephone far-end signals are co nnected directly to the Octopus. The Video Codec signal should be connected into the ‘SPK In’ connector.
In addition the interface includes a double-switch with four positions that is used to set up o utput level for different telephone systems. The user initiates the call through the telephone and the n switches to the Octopus by pushing the Headset button on the telephone (just like using headset with the telephone).
Setup Wizard The Setup Wizard is used to configure the type of unit, the input settings (type, level, and phantom selection) and setup the output level. Additional settings are available through the audio setup utility. Those include 3-way settings, color (frequency response) settings, and more, and will be detailed in the next chapter.
When setting the loudspeakers’ volume you should keep in mind that you need to avoid saturating the microphones with the speakers’ signal. The next step guides you through the setting of the four inputs of the units; each can be set as a microphone (meaning Matrix microphone), SR channel, or Aux channel.
When all the inputs are set the program will guide you to the output level setup. You can choose between Line-level output and Mic-level output. Use the slider to set the optimal level. The definition of the Line-level and Mic-level (as they appear in the spec sheet) apply to the slider position at the maximum level.
explanation on how to set the input levels. Master The first screen in setting a Master unit is setting the speakers’ volume, which is similar to the first screen of a Stand Alone unit; please refer to the Stand Alone setting chapter for details. The next screen is the input setting.
Additional Settings - Audio Setup Utility The Audio setup utility can help you set some additional parameters. These setting apply only to a Stand Alone or Master unit.
Phoenix Audio Technologies www.phnxaudio.com 16 The separate volume sliders are available when you select the Advanced mode, and the sliders change their functionality depending on the selection of the 3-way (if the selection was VC<->PC then the sliders will control the VC and the PC volumes).
