The D SERIES-TPS3A modules are three-pair audio sending modules compatible with RDL Format-A twisted pair products. These modules are designed
to be mounted in wall boxes, cabinets or other enclosures that allow users to connect audio sources. The -TPS3A models mount in RDL WB-1U and
WB-2U wall boxes, or in standard U.S. electrical boxes. The D-TPS3A features a white front-panel laminate with gray lettering that matches RDL
Decora©-style remote controls. The DB-TPS3A features a black front-panel laminate. The DS-TPS3A is constructed of stainless steel to coordinate with
RDL Decora-style stainless steel remote controls in commercial/industrial installations.
APPLICATION:
The D SERIES-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 D SERIES-TPS3A may not be connected together with any other sending modules.
The D SERIES-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 -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.
