Product information for RCS Audio-Systems FS-40:

The frequency shifter module is a specialized accessory for reducing acoustic feedback in public address systems and is designed specifically for use with Input 1 of the VLZ series central amplifiers. It is especially useful in environments where microphones are used alongside background music, and feedback suppression is essential.

By introducing a slight frequency shift of 7–10 Hz, the module effectively disrupts the formation of feedback loops without noticeably affecting audio clarity or voice intelligibility. The change in tone is so subtle that it remains virtually inaudible during normal operation.

This module is highly recommended for installations that involve microphone announcements in the presence of background music—such as retail stores, lobbies, or transit terminals.

Technical Details:


– Product Type: Frequency shifter module for feedback suppression
– Active Channel: Only affects Input 1 of the VLZ amplifier
– Frequency Shift Range: 7–10 Hz (virtually inaudible)
– Application: Feedback prevention for microphone input
– Compatibility: VLZ series (e.g. VLZ-6600A)
– Ideal for speech plus music environments
