    CONTROLS AND FUNCTIONS FRONT PANEL INPUT 1: LED indicator that lights up when a signal is detected in INPUT 1. 2.- INPUT 2: LED indicator that lights up when a signal is detected in INPUT 2. BACK PANEL OUTPUT 2: 100 and 70 V line high impedance speaker output terminals for channel 2. Only use one of the output lines.
  • Page 5 Use only one of the output lines. All the speakers must be connected in parallel and the sum of the power of all the speakers must not exceed the power supplied by the TFA-500. - 5 -...
  • Page 6 Two speaker zones In this application, two amplifiers in low impedance mono bridge mode are used together with the TFA-500 to get 2 independent 100 or 70 V lines. Place the STEREO/BRIDGE MONO selector in the STEREO position. Connect the mono output channel from each low impedance amplifier to the INPUT 1 and INPUT 2 inputs.
