Valcom S-560 Attenuator 20 Watts Pa Horn

Product Description

The VALCOM S-560 is a 20-watt attenuator designed for use in public address (PA) distribution systems. An attenuator allows the output volume of a PA speaker or horn to be reduced at the listening zone without affecting the rest of the system. The S-560 is rated for 20 watts of power handling, making it suitable for commercial and institutional paging and intercom installations where zone-level volume control is required. Licensed electricians and low-voltage communications technicians typically install this type of component as part of a structured audio distribution layout.

The S-560 is used in PA horn and speaker circuits where individual zone volume adjustment is needed. It is a common component in schools, warehouses, manufacturing facilities, and commercial office environments that rely on centralized paging amplifiers feeding multiple speaker zones. The attenuator is sold individually and is categorized as a PA horn accessory.

Key Features

• 20-watt power rating supports standard commercial PA circuit loads
• Provides zone-level volume attenuation without disrupting other speakers on the line
• Sold individually for flexible single-zone installation
• Designed for use with PA horn and speaker distribution systems

Compatibility

Designed as an OEM-style component for use in 70-volt or 25-volt PA speaker distribution systems requiring in-line or at-speaker volume attenuation up to 20 watts.

Installation Notes

Installation is typically performed by a licensed low-voltage or communications technician familiar with NEC Article 640 governing audio signal distribution wiring. De-energize the PA amplifier and confirm the circuit is unpowered before making any wiring connections. Follow the amplifier and speaker manufacturer wiring diagrams for proper series placement of the attenuator in the circuit. Do not exceed the 20-watt rated load on this device.
