# Program Delay Manager (PDM) input does not change when using Livewire

## Scope

This document applies to all Program Delay Manager (PDM) units when using Livewire as an audio source. The part numbers included are;

- 2001-00350 - 25/7 PDM with Analog/AES-EBU or Livewire
- 2001-00251 - 25/7 PDM with Livewire only

## Description

The 25/7 PDM can use **either** Livewire or (if equipped) the built-in Analog/AES-EBU audio card.

There are two methods to set the Livewire channel source feeding the audio to the PDM when using Livewire. Either scenario could appear **not** to change the Livewire Channel.

### Livewire Routing with Pathfinder or other control

In cases where Pathfinder or other routing software controls the audio (the Axia Dest Ch.) to the PDM, note that the channel number **DOES NOT UPDATE** on the front panel display. When viewing the route, do so with the same software used for routing. The current source routed to the PDM Destination is always displayed in Pathfinder in real-time even if Pathfinder did not make the route.

### Using the Front Panel

1. Using the front panel control pad, select **Axia** from the menu
2. Press the green checkmark button

3. Use the UP and DOWN arrows and select the **Axia Dest Ch.** menu option

4. Use the control pad to adjust the Livewire channel number

> [!NOTE]
> UP and DOWN move one number at a time.
> 
> LEFT and RIGHT move one hundred numbers at a time.
> 
> Holding any button increases its speed.

1. Press the green check when complete

> [!CAUTION]
