CORE transmitter VOLUME control: REMOTE and MUTE control ports
The CORE transmitter includes two audio control interfaces at its back panel:
•
MUTE
port, Normally Open, Euroblock 2 pin connector: it allows to connect an
external dry contact circuit (relay, switch, etc.) that, when closed, will MUTE the
WiSpeak wireless audio transmission, as well as the audio delivered at the AUX
OUT back panel connector. It is a very useful way of silencing the WiSpeak audio
system completely whenever an external emergency or alarm system, for
instance, must be activated
•
REMOTE
port, RJ45 connector: it allows connecting a WPaVOL or compatible wall
panel, providing the end user with a very simple volume control method, and using
a standard CAT5 cable to connect the wall panel to the CORE unit
The 3-positions
VOL CTRL
switch at the back panel of a CORE transmitter provides these
3 volume control options:
•
LOCAL & APP
: at this switch position, the general volume of the WiSpeak system
can be controlled using the front panel VOLUME knob and the WiSpeak grip app.
Both methods can adjust the volume within the minimum and maximum volume
range that can be defined using the WiSpeak grip app (Admin user) (*). The
REMOTE VOLUME port is disabled in this position
•
LOCKED
: when the switch is set to this position, the volume control keeps the
current value and remains blocked. It can’t be modified again
using any method,
unless the switch is set to a different position
•
REMOTE
: at this switch position, the volume can just be adjusted using the
WPaVOL wall panel connected to the REMOTE port. The CORE front panel
VOLUME knob and the WiSpeak grip app volume faders are then disabled in this
position

The general volume control, by any method used, can be limited within a given
minimum and maximum volume range, which can be defined using the WiSpek grip app
