Lowell 100LVC-DW Attenuator 100W 70V 25V 3db

Product Description

The LOWELL 100LVC-DW is a 100-watt in-line attenuator designed for distributed audio systems operating on 70-volt and 25-volt constant-voltage lines. It provides 3 dB of fixed signal reduction, allowing installers to fine-tune audio levels in specific zones without adjusting the amplifier output. The unit is sold individually and is intended for installation by low-voltage audio or electrical contractors working on commercial or institutional paging and background music systems.

This attenuator fits into 70V and 25V distributed speaker line applications found in commercial buildings, schools, houses of worship, retail spaces, and similar facilities. It is placed in-line between the amplifier output and the speaker load to reduce signal level by 3 dB at a specific zone or speaker tap point. The 100-watt power handling rating provides headroom for high-demand zones on larger amplifier systems.

Key Features

• 100-watt power handling for use on high-output distributed audio systems
• Compatible with both 70-volt and 25-volt constant-voltage line configurations
• Fixed 3 dB attenuation for predictable, consistent zone-level reduction
• In-line design simplifies integration into existing speaker wiring runs
• Sold as a single unit (each)

Compatibility

Designed for use in 70-volt and 25-volt constant-voltage distributed audio systems. Suitable as an in-line attenuator on speaker lines driven by compatible constant-voltage amplifiers.

Installation Notes

Installation should be performed by a qualified low-voltage technician or licensed electrician familiar with distributed audio systems and applicable local codes. De-energize the amplifier and confirm the system is powered down before making any in-line wiring connections. Verify that the combined speaker load on the zone does not exceed the 100-watt rating of the attenuator. Follow NEC guidelines for low-voltage wiring where applicable.
