Leviton Telcom 41920-A70 70V Mixing Audio Amplifier

Product Description

The LEVITON TELCOM 41920-A70 is a 70-volt mixing audio amplifier designed for distributed audio systems in commercial and institutional environments. Operating on the 70V constant-voltage standard, it allows multiple speakers to be wired in parallel across long cable runs without significant signal loss. The 41920-A70 accepts multiple audio input sources and combines them into a single amplified output, making it a core component in paging, background music, and public address installations. Licensed audio-visual and low-voltage contractors are the primary installers of this type of equipment.

This amplifier is suited for commercial, institutional, and light-industrial distributed audio applications where a 70-volt system architecture is specified. Typical installations include office buildings, schools, retail spaces, houses of worship, and healthcare facilities. The mixing capability accommodates multiple source inputs such as microphones, media players, or paging consoles feeding a single amplified 70V output line serving transformer-equipped ceiling or wall speakers throughout the space.

Key Features

• 70-volt constant-voltage output for long-run distributed speaker systems
• Multi-input mixing capability supports simultaneous audio sources
• Designed for commercial paging, background music, and public address applications
• Sold as a single unit for straightforward procurement and replacement

Compatibility

Designed as an OEM-style replacement or new-installation amplifier for 70-volt distributed audio systems using transformer-tapped speakers conforming to the 70V constant-voltage standard.

Installation Notes

Installation should be performed by a licensed low-voltage or audio-visual contractor in accordance with applicable local electrical codes and NEC Article 640 governing audio signal processing equipment. Disconnect and de-energize all power to the system before making any wiring connections to the amplifier. Ensure all speaker transformer taps and total load impedance are calculated and within the amplifier rating before applying power. Do not exceed the rated input or output capacity of the unit.
