In a cinema environment, the playback room and the screening room are separated, so the sound output through the surround bass management channel output interface 40 cannot be heard in the playback room, resulting in the operator being unable to understand the real-time sound effect of the playback. In this embodiment, a monitoring speaker 60 is provided, and when outputting audio, it is output from both the surround bass management channel output interface 40 and the monitoring speaker 60. The operator can determine the sound effect currently being played through the sound transmitted from the sound outlet 111, so as to make timely adjustments and maintain a good sound effect.
[0039] For example Figure 1 As shown in FIG. 1 , as another implementation of this embodiment, a volume control knob 70 is provided on the front panel 11. The volume control knob 70 is electrically connected to the main control board 20 and is used to control the output volume of the monitoring speaker 60. By setting the volume control knob 70, the volume of the monitoring speaker 60 can be flexibly controlled, so that the operator can adjust the volume to a suitable level and obtain sound information accurately and clearly.
[0040] For example Figure 3As shown, as another implementation of this embodiment, a monitoring unbalanced output interface 80 is provided on the rear panel 12.
