FAQ 151-2002-en

The T93 channel amps. ref. 5613, 5614, and 5648, feature 2 inputs and 2 outputs.

  1. Can these amplifiers be programmed for two channels since they have 2 inputs?
  2. What use would there be in having a second input at the same frequency?
  3. Would this cause ghosting?
Respuesta: 

The T93 channel amplifiers feature a particular system for mixing channels:

  • The channels enter the input loop, all along the links.
  • The channel corresponding to the frequency at which the amplifier is tuned, is accepted by it and is consequently amplified.
  • The rest of the channels are rejected and can pass through until they find their corresponding amplifier tuned at their frequencies.
  • In the same way, they have two outputs for mixing the channels coming from each amplifier.

This system is commonly called loop-through because the signals that are not tuned with the channel amplifier can pass through almost without attenuation.

  • Therefore as we have explained, the answer is no, as the two inputs of the amplifier can only be used for the loop-through.

The aim of the two connectors at the input and output of the amplifier is simply to avoid the use of splitters at the input and combiners at the output.
