Benefits:

  • Built-in smooth controls over gain and gain slope (models HA205R30, HA205R65, HD205R30, HD205R65) or discrete
  • built-in units (HA205R3J, HA205R6J, HD205R3J, HD205R6J);
  • A moulded case;
  • Switchable gain of the forward channel,;
  • An active or passive feedback channel;
  • A switchable input attenuator for the feedback channel;
  • Test points:

                 at the input- bi-directional

                at the output- directional
