Feed-Thru Operation
The Addressable Amplified Speaker can be programmed to perform as a Lead unit or as a Slave unit in a
speaker grouping. This function is referred to as “Feed-Thru” operation and can be activated via the
CARD Suite Programming Software. This operation is primarily used in an RF installation and allows
the Lead Addressable Amplified Speaker to receive the source audio signal via the RF airwaves and
provide hardwired, 600-ohm redistribution of the audio (and page control, if required) to one or more
speakers within a grouping. This configuration could greatly reduce system costs by limiting the number
of RF speakers required.
When in Individual operation, the Lead speaker simply acts as a receiving point for the Slave speaker(s),
allowing the Slave speaker(s) to be addressed individually without activation of the Lead or other Slaves.
When in Follow-me operation, the Slave speaker(s) will activate upon activation of the Lead speaker.
This access includes adjusting volume control settings.
Refer to page 26 for detailed information.
Volume Adjustments
Each speaker assembly’s output volume can be adjusted via four different methods:
 Remotely, using DTMF signaling
 Programmed prior to installation using CARD Suite
 Locally using the optional Model 12506-001 L-pad
 Automatically, utilizing the ALA (Automatic Level Adjustment) feature. This feature would be used
if steady high noise levels sometimes occur but are not present continuously.
Remote Volume Adjustment
With Automatic Level Adjustment Disabled
To adjust the speaker output volume with the Addressable Amplified Speaker programmed for DTMF
selective operation, begin a broadcast using the speaker’s local address (Address 1) followed by a “#”
symbol. When the speaker becomes “active”, transmit a DTMF “*” symbol. Upon receiving the “*”, the
speaker will broadcast a test tone for a programmable amount of time. During this tone, transmit a “*” to
increase the volume or transmit a “#” to decrease the volume. Each press of the “*” will increase the
volume one level and each press of the “#” will decrease the volume one level. The speaker will
broadcast a test tone at the new volume level each time it is changed. Volume can be increased or
decreased between minimum and maximum in 11 steps. A low frequency warning will be broadcast
when the volume has reached either its upper or lower volume limit.
If the speaker under test is programmed for Generic Operation, it will have provisions for programming a
DTMF volume control address via the CARD Suite Programming Software. When properly
programmed, the speaker can be accessed for volume control by simply transmitting its volume control
address and changing the volume as described in the previous paragraph.
CARD Suite includes a test tone duration setting that is programmable between .5 and 6.0 seconds in .5
second increments. This test tone will automatically extinguish at the end of the pre-programmed
duration time or can be manually extinguished by sending a DTMF digit other than “*” or “#.” The
speaker stores its volume setting when the test tone ends.
