Qt X 805/805D Rear Panel
1. LCD Display
The LCD display indicates system statuses and parameters. Users may navigate
through the display to view the current IP address and network mask of the
device, view current operating mode of the device (unconfigured, configured,
updating firmware, etc.) and view any faults present.
2. Function/Navigation Buttons
Function/navigation buttons allow navigating through information provided in the
LCD display.
3. Factory Reset
Insert pin to depress the switch, press and hold for 10 seconds. This will return
the unit to factory settings, cause all configuration to be cleared and the device
to reboot.
4. Power Connector
Connection for an external (included) 48V power supply.
5. Network Control & Media Ports - 2 ports
RJ45 Gigabit Ethernet port connectors support AVB and Dante media streams
(Dante is only supported on 805D models). In dual cable mode the left one
(#1) the default media port, but in single cable mode it can be both control and
media. The right (#2) port is the default control port in dual cable mode. Port 2 is
disabled in single cable mode.
6. 4-Pin Logic I/O - 2 ports
Two triggers for zone muting or indication for paging application. See page 13
for additional information.
7. 4-Pin Contact Closure - 2 inputs
This contact closure is provided in order to mute audio and sound masking in the
zone or system in the event of a fire emergency or request to page. should be
connected to the fire alarm panel (port 1) or paging system (port 2 - configured
as Push-to-Talk).
8. 4-Pin Privacy Light Output - 2 outputs
The privacy lights ports enable connections to (2) privacy lights panels which
indicate when sound masking is enabled in a certain zone. Each can be assigned
to a different zone when configuring the system in the software or web interface.
9. 3-Pin MIC/Line Audio Inputs - 2 inputs
Two MIC/line audio inputs may be connected to an external audio source such
as a music player or an external paging controller. This allows distribution of
networked audio throughout the connected zones.
10. Line Level Outputs
The Qt X 805 supports up to eight individual channels of sound masking and
audio. These line level outputs should be used when utilizing an external
70V/100V amplifier sized for a distributed loudspeaker load. Speaker connections
are made via 3-wire connections to black euroblock connectors. Each output
can be connected to an amplifier channel or 3rd party component (i.e. Tesira)
with line level inputs.
11. Class 2 Speaker Outputs
The Qt X 805 supports up to eight outputs of sound masking and audio. Speaker
connections are made 2-wire connections to yellow euroblock connectors. Each
output can accommodate (1) 4Ω or (2) 8Ω DS1300 speakers.
IMPORTANT: The Qt X 805/805D is limited to 8 individual channels of sound masking
outputs. Either the Line Level or Class 2 types should be assigned to an individual
numbered output. The settings are mirrored on each of the same numbered outputs
so it is possible (but not recommended) to connect to the same numbered output on
both types.
