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 -TPS3A may not be connected together with any other sending modules.
The -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.
