The Sound Recording Amplifier is a Directional EC Unit in the Stationary Security Service game mode of Arknights, introduced in the fifth Dispatch Cycle, "Clamour Zone", and can only be used in Nomadic Border Town.

The Sound Recording Amplifier passively amplifies the Physical damage dealt by friendly units by 20%, which is doubled if they are behind the deployed Amplifier. In addition, the Amplifier will always be in the Waiting Zone at the start of an operation.

When the Sound Recording Amplifier is deployed, it behaves similarly to the Aspect of Annihilation introduced in Zwillingstürme im Herbst, where it will be attacked by friendly units, who attacks it over enemies under normal circumstances due to its aggression level of 1 but will keep track of the highest damage it takes in a single hit; once the Amplifier is destroyed, five projectiles will be released straight ahead to deal splash Physical damage to the first enemy struck equal to the aforementioned tracked damage.
