Model 240-X Audio Distribution Amplifier

General:
  Model 240-X is based on a dual channel 6-output per channel(2x6) audio distribution amplifier(ADA) module. The 240-X may be 
configured as 1x12 balanced in/out ADA, 2x6 balanced in/out ADA, 1x24 unbalanced ADA or 2x12 unbalanced ADA. With RM200 series
mounting tray, 4 standard connector panels are provided to meet different applications. XLR type connector, RCA jacks, D-sub 9 pin and
terminal board in/out connector may be applied. Custom designed connector panel will be fabricated for your system requirement.
Standard system gain is +20dB to -6dB. Microphone level gain ADA is also available.

Features:
* Balanced or unbalanced audio format.
* Amplifier standard gain is +/- 20dB to -6dB. Up to +66dB gain for microphone is available.
* 1,3 or 10 module frames are available.
* Front panel input and output test points provide easy metering of measures.
* Independent power supply on the card or external  UL/CSA approved power unit.
* LED power indicator is on the board.
