Valcom, Inc V-LPT One-Way Paging Adapter 45ohm 1000ohm 20ohm

SKU CH-AKNR-2W641

Converts 45 ohm talkback outputs to line level for Valcom self-amplified speakers or one-way amplifiers via screw terminals with adjustable volume pot

  • DetailsOne way Paging Adapter
  • Matches 45 ohm talkback outputs to amplified speaker inputs
  • Screw terminals simplify audio input and output wiring
  • On-board level pot adjusts paging volume precisely
  • Converts 1000 ohm input to under 20 ohm output
  • Designed for Valcom self-amplified speakers and horns

Impedance Matching Module

The Valcom V-LPT converts 45ohm talkback speaker outputs to the level and impedance required by one-way amplifiers or self-amplified speakers and horns. It is intended for installers integrating Valcom V-TCM station cards into paging systems. The adapter bridges the impedance gap between talkback circuits and line-level inputs. Buyers needing a two-way audio interface or a different impedance range should look elsewhere.

Screw Terminal Connections

Audio input and output connect to screw terminals on the unit for secure, tool-terminated wiring. A built-in level potentiometer allows on-site volume adjustment without external controls. The compact module mounts inline within the signal path. Installers who require plug-in connectors or rack-mount hardware will not find them here.

1000ohm Input to Under 20ohm Output

The adapter presents a 1000ohm input impedance and delivers an output impedance below 20ohms to drive amplified speakers directly. This specific conversion determines compatibility with the target amplifier or speaker input stage. Systems requiring a different input or output impedance value cannot use this module.

Questions about this item

What input and output impedances does the V-LPT adapter handle?

The adapter accepts a 1000 ohm input and converts it to an output of less than 20 ohms for Valcom self-amplified speakers or line-level amplifier inputs.

What type of physical terminals are used for wiring the V-LPT adapter?

Audio input and output connections are made via screw terminals on the unit.

How is the volume level set on the V-LPT adapter during installation?

Volume is adjusted by turning the level potentiometer on the unit after wiring the screw terminals.
