Presentation Transcript

  1. LINE AMPLIFIERS Increase or Decrease Line Level Signal Strength • Amplify signals for long cable runs • Increase / decrease levels for signal conversion • Convert unbalanced to balanced signals • Convert balanced to unbalanced signals

  2. LINE AMPLIFIERS UNDERSTANDING AUDIO SIGNAL STRENGTH

  3. LINE AMPLIFIERS COMMON AUDIO SIGNAL TYPES AND WIRING (MANY VARIATIONS EXIST ) Professional / Broadcast Consumer

  4. LINE AMPLIFIERS Balanced to Unbalanced or Unbalanced to Balanced Conversion Adjust Signals from -10 dBV to +4 dBu or +4 dBu to -10 dBV • Two channel amplifier • Adjustable Gain -12 to +20 dB • Requires dedicated power supply STA-1 • Two channel amplifier • Adjustable Gain -14 to +24 dB STA-2A • One channel (mono) amplifier • Adjustable Gain -14 to +14 dB STA-1M

  5. LINE AMPLIFIERS Connectorized for Easy Conversion • Converts two balanced lines to unbalanced • Decrease from +4 dBu to -10 dBV • -10 dBV output with -6 to +6 dB adjustment • Dual XLR inputs to RCA outputs FP-BUC2 • Converts two unbalanced lines to balanced • Increase from -10 dBV to +4 dBu • +4 dBu output with -5 to +10 dB adjustment • Dual RCA inputs to XLR outputs FP-UBC2

  6. LINE AMPLIFIERS • Stereo unbalanced to balanced conversion • Adjustable +2 to +22 dB Gain • Dual LED VU for precision calibration • Stereo outputs plus summed mono output ST-UBA2 • Convert six unbalanced lines to balanced • Increases -10 dBV to +4 dBu • Adjustable -5 to +10 dB Gain • Great for “surround sound” applications FP-UBC6

  7. LINE AMPLIFIERS Stereo Audio Format Converters with Concurrent Bi-directional Operation Unbalanced lines to balanced line section • Increase -10 dBV to +4 dBu • +4 dBu output with -25 to +9 dB adjustment • RCA inputs to XLR or terminal block outputs • Summed mono output on terminal block Balanced lines to unbalanced line section • Decrease +4 dBu to -10 dBV • -10 dBV output with -25 to +5 dB adjustment • XLR or terminal block inputs to RCA Dual LED VU meters for each output RU-AFC2 • Same features as above except: • Off to +12 dB adjustment for both converters • No terminal blocks EZ-AFC2

  8. LINE AMPLIFIERS Telephone Line Simulator • Used for older style key telephone systems • Interfaces paging or radio systems • Simulates an incoming TELCO line • Often used for special applications ST-TC1
