Specications

Directional Pad:

• Four-way directional buttons
with center button.

Power LED Screen:

• Options and setting menu

• Mixer and network information

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

In order to select primary or secondary mixers within a daisy chain of Stingrays, you can identify the units within this menu selection. 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

unit is selected as a primary, all units linked above in the daisy chain will be cut off from the unit. When the mixer is set to the primary mixer,
the connections to the intended mode of communications will turn on and the settings will be applied to all secondary units below. When
a mixer is set as a secondary unit, its connections to communication modes will be disabled and the settings will be inherited from the pri­mary unit. Also if attempting to make a unit not connected to a daisy chain, an error message “can’t be set as secondary” will be prompted.

2. automatic mixer selection

Within this menu option, users will nd either the mixed microphone input or mixed line input options. When using mixed mi­crophone 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 representa­tion 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 be­tween 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 vol­ume 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 stat­ic IP addresses for Stingray units so it does not change. The dashboard gives the user remote ac­cess and control to the Stingray and allows for more setting options than directly on the device.

Mic Mixer Settings:

When using Mic Mixer selection, this allows the use of a total of four microphone
inputs and four line inputs. The four microphones inputs will have beam forming, noise
cancellation, echo cancellation, and automatic gain control applied and combined into a single
audio output. For this to function properly, all microphones being used must be the same model. In
the browser based dashboard interface, there are a number of different settings that can be adjusted.

Microphone Tab - Adjust microphone sensitivity for all microphones attached to the Stingray unit.
Adjuments will apply the sensitivity to all microphones as there is no individual sensitivity settings.

Speaker Tab - Adjust speaker output volume using the master volume slider tool which increases
overall volume. Users can adjust the balance of the speaker output of the USB, SIP, and Analog inputs
to create level sound. This is useful if multiple devices are bridged with different volume input levels.

Line Tabs - There are individual settings for each line input and users can set either “Podium” or “Aux­iliary” for the inputs. If “Not Set” is selected, the line will not function. Hardware attached to the line
inputs will not have beam forming capabilities, but all other DSP processing will be applied.

The Podium setting input allows the users to make the input a priority speaker by allowing voice lift
which also broadcasts the user through the connected speakers. Users can also adjust the balance of
the local speakers, secondary levels, and the send out level. Noise Cancellation, echo cancellation, and
automatic gain control will be applied to this input.

The Auxiliary setting input allows the users to use the line for audio that does not require noise cancel­lation, echo cancellation, or automatic gain control. This is typically used for media like music, presenta­tions with sound, or movie clips which allows the audio to be transmitted and output to the local speakers.

Line Mixer Settings:

When using Line Mixer selection, this disables the microphone inputs, reducing the number of inputs
to four. The Line Mixer settings will still receive noise cancellation, echo cancellation, and automatic

gain control applied to the audio. Like the Mic Mixer Setting, many of the adjustable eld are the same.

Speaker Tab - Adjust speaker output volume using the master volume slider tool which increases
overall volume. Users can adjust the balance of the speaker output of the USB, SIP, and Analog inputs
to create level sound.

Line Tabs - There are individual settings for each line input and users can set either “Podium”,
“Auxiliary” and “Mixer” for the inputs. If “Not Set” is selected, the line will not function. Hardware
attached to the line inputs will not have beam forming capabilities unless using the Mixer setting.

The Podium setting input allows the users to make the input a priority speaker by allowing voice lift
which also broadcasts the speaker through the connected speakers. Users can also adjust the balance
of the local speakers, secondary levels, and the send out level. Noise Cancellation, echo cancellation,
and automatic gain control will be applied to this input.

The Auxiliary setting input allows the users to use the line for audio that does not require noise can­cellation, echo cancellation, or automatic gain control. This is typically used for media like music, pre­sentations with sound, or movie clips which allows the audio to be transmitted and output to the local
speakers.

The Mixer setting allows users to beam form using the line input. In order for beam forming to work
properly, more than one line must be used and microphones must be the same model.

When selecting “SIP Client Setup”, users will be prompted with a screen with Conguration, Manage­ment, and Status & Diagnostics tabs. You will nd the following settings under each menu.

The Stingray ability to adapt to variable conference room sizes through daisy chaining gives users the
capability to create multiple zones or combine the zones together to use all the hardware assets to
cover a large space. It is recommended all Stingray units are connected to a mode of communication
which allows the unit to become a primary unit. Illustrated below is the zoning concept which shows that

with ve units, you can either have ve seperate zones to one single large zone or any number inbetween

there with just a simple selection on our unit or any mechanical switch. This allows users to easily convert

their conference room sizes without the need to have an engineer rewire or recongure the equipment

that are already in place. This provides a solution that quickly and easily solves the changing spaces.

15

In order to daisy chain Stingray units together, on the back panel will be two RJ45 ports marked “Link
Up” and “Link Down” under the daisy chain bracket. The “Link Down” port is used to connect a primary
unit to a secondary or a secondary to another secondary down the chain. The “Link Up” port is used
to connect to units above by connecting “Link Down” from the unit above to the secondary “Link Up”.

Connecting a secondary unit to the primary, the RJ45 cable will
leave the primary unit connected to “Link Down” and will con­nect into the secondary “Link Up” slot.

If the conference room setup requires to daisy chain more than
2 units, the third unit will connect to the secondary unit in the
chain with the RJ45 cable leaving the “Link Down” and connect­ing to the “Link Up” on the third unit.

Connecting additional units will follow the same procedures with a maximum of 15 Stingray units con­nected together (1 primary unit chained to 14 secondary units).

When changing one of the secondary units to a primary unit, the secondary units linked below the
new primary will now receive the settings from the new primary and the chain will seperate from
the units above the new primary unit. In order for a Stingray mixer to become a primary unit, it
must have connection to a mode of communication, either through USB, SIP or Analog connection.

To congure a Stingray mixer to a primary or secondary unit, it can be completed either directly on

the device (refer pg. 6), through the browser device dashboard (refer pg. 9) or a mechanical switch can

be congured to be used with the control port on the Stingray back panel.

*Recommend to use minimum CAT5 shielded cables with improved audio quality with CAT6 & CAT7 shielded cables.

Zoning Notes

Unit set to Primary:

-Any unit can be congured to be a primary unit if it has a connection to a mode of communication

-Mode of communications will be turned on (USB, SIP, and Analog)

-Primary unit will dictate parameters to all secondary units below in the chain

-Daisy chain will be cut off at the next primary unit down the chain

-Podium and Auxiliary line channel features are enabled

Unit set to Secondary:

-Assume the settings of the primary unit

-Mode of communication connections are disabled

-Podium and Auxiliary line channel features are disabled, but ordinary line inputs function normally

*Note - A unit can have primary settings programed, but when switched to a secondary unit, the set­tings will be changed to the connected primary settings. The unit can switch to the primary unit at any
time and the unit will revert back to the programed primary settings as conguring a unit to second­ary unitdoes not remove the primary settings of the unit.
