The Phoenix Audio Technologies - Stingray Distributed Array Mixer is an all-in-one smart mixer that uses
proprietary distributed array technology. The Stingray was designed to be a simple solution for the complex
needs of corporate and professional conferencing spaces. While focusing on this principle, we created a ex-
ible Distributed Array Mixer that can be a solution for any conferencing room setup. Even with the evolution
of variable number and size of conference rooms, the Stingray provides users with the ability to adapt to the
situation to create an environment where everyone can speak freely and naturally without compromising
audio quality.
Phoenix Audio Technologies believes that high quality audio should be easy to install and simple to use.
Users shouldn’t need to be audio experts to integrate or use our products. Our philosophy is that good
audio solutions should be complicated on the inside, so that they can be exible and simple solutions
that everyone can use. To perfect our craft, our company specializes in audio products for conferenc-
ing, which can be used either alone or to complement video solutions. We design and manufacture
products that address the fast pace changes in communication trends, conferencing environments, and
connectivity technologies.

The Stingray can be congured on the mixer using the directional pads and the menu
selections or through any browser on a device connected to the local network. In the following
pages, nd the options and settings that can be modied to t the needs of the conferencing space.
The LCD Screen displays the device name, the device chain location number and the local IP
address the device is connected. Using the directional keys will cycle the microphone and line out levels
screen and also the menu access screen. To access the menu screen, press the center “Enter” button.

When accessing the menu, there will be seven selections which allow
the user to congure the mixer. In order to make the
selections, you can either press the center “Enter” key or the right di-
rection on the directional pad. To go back on the screen, press the left
direction to go back to the previous screen. The
selections and detailed descriptions are listed below.
1. primary/secondary selection
Inordertoselectprimaryor secondary mixers withina daisychainofStingrays,youcan identify the unitswithin this menuselection. Note
that the primary mixer is the unit that is connected to the intended mode of communication (i.e. SIP, USB, or Analog) and when a specic
unitis selected asa primary,all units linkedaboveinthe daisy chainwillbe cut offfromthe unit. Whenthe mixer isset to theprimarymixer,
theconnections tothe intendedmode ofcommunicationswill turnon and thesettings willbe appliedtoallsecondaryunits below.When
amixer isset as asecondaryunit, itsconnections tocommunicationmodes willbe disabled andthe settings willbe inheritedfromthepri-
maryunit. Alsoifattemptingtomakea unitnot connectedtoa daisychain, anerrormessage“can’tbeset assecondary”will beprompted.
2. automatic mixer selection
Within this menu option, users will nd either the mixed microphone input or mixed line input options. When using mixed mi-
crophone input settings, the DSP will process and beamform the microphones inputs then add the line inputs. When using the
mixed line input option, the mixed microphone inputs will be disabled and the DSP processing will be dedicated to the line input.
3. microphone input setting
Users can control the microphone sensitivity within this menu as an entire group. There is a graphical representa-
tion of the ound levels the mixer detects from the microphone to better assist in adjusting the appropriate levels. Within
this menu, each microphone can be isolated and you can listen to the microphone that is highlighted on the LED Panel via
the monitor output or through the speaker outputs. The individual microphones can be selected with the directional pad.

4. line input setting
The menu is congured with each line input channel with the option to mute, set as auxiliary or podium. The main difference be-
tween auxiliary or podium selection is that the auxiliary is used for outputs that do not pick up local sounds, which do not require
echo canceling. Podium mic function also has the capability to voice lift the user onto the local speakers.
5. speakers setting
The settings allow you to control the maximum output to the speakers with the master volume. Users can also balance the vol-
ume of audio inputs from USB or SIP from this menu.
6. general setting
Users can restore to factory default settings, set the display time out duration, and the display brightness.
When selecting the “restore factory default”, the user will be prompted with a message to ensure the intention of the reset.
The “display timeout” setting allows for durations of 30-second, 60-seconds (default), or 2-minutes.
For the “display brightness” setting, there are 6 levels of brightness available with the default set at the highest setting.
7. information
The information selection gives the programed settings in one location. The menu provides information if the Stingray is the
primary or secondary unit, mixed microphone or line input, current IP address, mac address, unit name, DSP version, SIP Version,
serial number and unit ID.

The dashboard interface can be accessed from any browser on a device connected to the
local network, using the IP address displayed on the Stingray. It is recommended to use stat-
ic IP addresses for Stingray units so it does not change. The dashboard gives the user remote ac-
cess and control to the Stingray and allows for more setting options than directly on the device.
