Altronics A4824 User manual

The UT2612A provides an XLR microphone input, two RCA jack inputs on the front panel for the left and right channel input source. The
RCA input jacks accepts to receive the signals from PC, mobile phone or other media player (standard - 10 dBV consumer level signal).
The XLR MIC provides 24V phantom power allow using the condenser or dynamic microphones, and amplified by high quality pre-amp
circuit. Normally set the rear panel GAIN switch at the position of NORM (normal) gain. If consistently low mic levels are requested, please
set the switch to the position of HIGH gain. The XLR MIC source is sent by UTP pair A. The left and right of RCA jack inputs are sent by
UTP pairs B and C.
The module use all three pairs of cable for XLR and RCA input sources, this means this module could not receive input signals from other
transceivers.
Provide the power to this module via the Terminal Block at the back panel from a 24Vdc power supply. Also provides the power to all other
connected modules. UT2612A also accepts the remotely power from any other module, signal distributor or CSP power supply through UTP
cable. A front panel LED lights when the module is powered.
CSP modules provide high audio performance better than shielded cabling. Design in simply, quick of installation, excellent flexibility, reject
the unexpected hum noise, low noise, and low distortion. The best choice for installations in economical twisted pair products.

TYPICAL PERFORMANCE
STEP1: Normally set the rear panel GAIN switch at the position of NORM (normal) gain. If consistently low mic levels
are requested, please set the switch to the position of HIGH gain.Note: Please set the switch to the position of NORM
to avoid any unexpected clipping if both normal and low level MIC signals are requested.

STEP 2: Connect 24Vdc to the Terminal Block. Or make sure the module is powered through the UTP cable from
another module.Note: The front-panel power LED will be illuminated if this module is powered. If this module is
powering other modules through the cable and if there is a wiring short, the short must be cleared then power
must be turned off to this module for 10 seconds to reset the internal protection circuit.
STEP 3: Connect the UTP cable and mount the module into the mounting box.
