The RDL AF-TPR1A module is a single-pair audio receiving module compatible
with RDL Format-A twisted pair products. This module is designed to be
mounted in wall boxes, cabinets or other enclosures that allow users to
connect external equipment. The RDL AF-TPR1A is an APPFLEX series product
that is compatible with various APPFLEX wall-mount, cabinet-mount and
tabletop enclosures.
APPLICATION: The RDL AF-TPR1A modules feature an XLR output jack. A rear-panel
switch set during installation determines which of the three FORMAT-A
pairs is buffered to feed the module output. The audio signal received
from the selected pair of the RJ45 INPUT jack feeds the XLR audio output
jack. The output level from the XLR jack is set to either MIC or LINE
level during installation using a rear-panel switch.
This module receives signal from only one cable pair, so the D-, DS-,
and AF modules have a second RJ45 jack to connect cables to additional
receiver modules. Installers simply connect the conductors of two cables
in parallel on the EM- model terminal block. Two other single-pair receivers
may be chained to the second RJ45 jack, or a single two-pair receiver
may be connected. In addition to completing the reception of signals from
all three FORMAT-A pairs, additional receivers may be connected to the
same twisted pair feed. The bridging input circuits used in all FORMAT-A
twisted pair receivers allow connection of up to 10 receiver outputs for
each cable pair. The possibility of multiple receiver locations adds enormous
flexibility in the design of audio routing systems using RDL FORMAT-A
products. The power pair and all three audio pairs are fed through both
rear-panel RJ45 jacks.
The RDL AF-TPR1A may be powered directly from a 24 Vdc power supply using
the rear-panel detachable terminal block. Local power connected to the
module is also fed to all connected remote modules. The RDL AF-TPR1A may
be remotely powered through the twisted pair cable from any other module,
signal distributor or RDL power inserter connected to the same twisted
pair cable. Module power is indicated by a front-panel LED.
The RDL AF-TPR1A features superior audio performance that rivals or exceeds
shielded wiring. Design simplicity, ease of installation, unsurpassed
flexibility, automatic fused power, exceptional hum rejection, low noise,
and low distortion provide designers and installers the optimum choice
in economical twisted pair products.
