A 4460 4 x 8 Stereo Switcher
®
6.0 SET UP & OPERATION
The system is controlled primarily via the connected touchscreen wallplates. These allow selection of audio sources and lev-
el adjustment at each zone. A master wallplate control allows control of all zones, while the zone wallplate allows control
for the zone only.
Connect all audio sources and output zones to the main controller using standard RCA cables. Connect all wallplates to
the system using UTP data cable. We recommend first connecting the plates to the controller using patch cables prior to
installation on the wall so that you can perform setting up of zone names, source names and adjust all settings (see sec-
tion 9.0).
For Bluetooth audio streaming, each zone wallplate is fitted with a Bluetooth audio receiver. A global bluetooth input can
also be set allowing a single zone to provide Bluetooth audio to all connected zones in the system. For example, a smart-
phone at Reception area could be streaming audio to all zones in a function venue.
Finally, connect any closing contact triggers you wish to use (see section 8.0). These can be used to playback an MP3 file
from the micro SD card when contacts are triggered from for example, a door bell, IR beam or similar. It could also be used
to play timed announcements when combined with an appropriate timer fitted with closing contacts.
7.0 INPUT & OUTPUT LABELS
The inputs and outputs which are displayed on the LCD, can be easily customised by making changes to the text files on
the supplied Micro SD card or alternatively use the master wallplate control. To change the labels via SD card follow the
steps outlined below:
1. Disconnect power from the A 4460.
2. Remove the Micro SD card from the rear of the A 4460 by pushing it in until it clicks, and then releasing it.
3. Insert the Micro SD card into a PC or Laptop with a Micro SD slot. (If the computer doesn't have this, a compatible
Micro SD card reader will be required).
4. Navigate to and select the Micro SD card.
5. Inside the card will be folders labelled "Inputs" and "Outputs".
6. To change the Input labels, select the Inputs folder and open the relevant text file. I.e. The "Input2.txt" file to change
the Input 2 label. Once the file is opened with a text editor, change the label to something meaningful to
a maximum of 10 characters (only standard keyboard characters are accepted).
7. Repeat step 6 for the output labels.
8. Once complete, follow windows safe removal procedures for ejecting the Micro SD card.
9. With power still disconnected from the A 4460, insert the Micro SD card. Push it in until it clicks.
10. Reconnect power to the A 4460 and press the "Power/Standby" switch to turn the unit on.
11. The new labels should now be displayed on the LCD.
8.0 AUDIO TRIGGERS
On the rear panel are four hardware based triggers for connection to a closing set of contacts. When contacts close this
will trigger the playback of an MP3 audio file on the micro SD card. These are stored in the TRIG1 to TRIG4 folders. A
further 6 software based triggers are also available for playback from folders TRIG5 to TRIG10. These are triggered by the
accessing the "Activate Triggers" button under settings. Or by selecting the "System" zone on the master wallplate and
then pressing "Triggers" button. All audio triggers are a system wide playback and will override the audio sources playing
in each output zone when playback is triggered. Once the MP3 has finished playback, each zone will return to previously
selected audio source.
