The RDL AF-TPS1A module is a single-pair audio sending 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 audio sources.The RDL AF-TPS1A is an APPFLEX series product that
is compatible with various APPFLEX wall-mount, cabinet-mount and tabletop
enclosures.
TheRDL AF-TPS1A modules feature an XLR microphone input. The module provides
IEC 24 V phantom and accepts input signals from both dynamic and condenser
microphones. The input signal is amplified using a studio-quality microphone
preamplifier optimized for normal operating levels. The rear-panel GAIN
switch is normally set by the installer for NORM (normal) gain. If consistently
low mic levels are expected, this switch may be set to the HIGH gain position.
The pre-amplified microphone source is routed to one output cable pair
selected during installation using a rear-panel switch.
This module drives only one cable pair, therefore it accept signals and
power from other mic-level or line-level Format-A senders. Two other single-pair
senders may be chained with the RDL AF-TPS1A, or a single two-pair sender
may be connected. If three single-pair senders are connected together,
each sender must feed a different pair: A, B or C. The RDL TPS1A must
be set to feed pair A if it is connected together with an RDL two-pair
sender that feeds stereo audio on pairs B and C. The power pair and all
three audio pairs are fed through both rear-panel RJ45 jacks.
The RDL AF-TPS1A 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-TPS1A 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.
RDL FORMAT-A 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.
