In a transmission apparatus, a monitor unit monitors a signal level and generates a monitored value; a level control unit controls the level of the input signal in accordance with the monitored value; an output amplification unit amplifies and outputs the level-controlled signal; and a control unit controls unit operation statuses in accordance with setting information. The control unit recognizes the period of duration of a single level in the input signal, from the signal format given by the setting information, and performs variable control of at least one of a monitor time constant, a response time from the signal input to the monitor unit until the generation of the monitored value, and a level setting time constant, a response time from the input of the monitored value to the level control unit until the execution of level control, in accordance with the period of duration of the single level. |
