The RDL AF-TPS3A module is a three-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 AF-TPS3A is an APPFLEX series product that
is compatible with various APPFLEX wall-mount, cabinet-mount and tabletop
enclosures.
The -TPS3A modules features an XLR microphone input and two RCA phono
jack inputs, one for the left channel source and one for the right channel
source. The unbalanced inputs are designed to receive standard -10 dBV
consumer level signals. The microphone input provides 24 Vdc IEC phantom
voltage and accepts both dynamic and condenser microphone signals. The
input signals are amplified using studio-quality preamplifiers optimized
for normal operating levels. A rear-panel GAIN switch is provided to set
the amplification of the microphone preamplifier. This 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 pair A. The buffered left and right line-level
inputs are routed to output cable pairs B and C.
These modules drive all three FORMAT-A cable pairs, so they are not equipped
to receive inputs from other sender modules. The RDL AF-TPS3A may not
be connected together with any other sending modules.
TheRDL AF-TPS3A 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-TPS3A 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.
