This guide will walk you through the audio settings available for the AVP products
Requirements:
- Layer 3 network with a static route enabled
- Putty or some other telnet program
The 2G+Omega and 3G+AVP Transmitters and Receivers have the ability to adjust the volume level on the 3.5mm Stereo Out jack.
The 2G+ Transmitters and Receivers have the ability to adjust the audio delay for Lipsync correction on the 3.5mm Stereo Out Jack. There is NO volume control.
Note: The volume control only affects the Stereo Out of the AVP models and does not affect the HDMI audio. There is no way to adjust the volume level of the HDMI signal; the volume level that goes into the Transmitter is the level of HDMI volume across the entire system for that source.
The volume control is available in increments of ±1.5 db (decibels) with a range of +6 db to -39 db, and Mute.

This is a drawing of the bottom of the AVP Transmitter.

The rack unit features (3) 718AVP transmitters inside of it. So there will be 3 sets of these buttons on the bottom of the transmitter.
This guide will cover the use of the telnet program Putty.
Open the putty.exe program and then we need to change a few options to make using putty easier.
1. Select Keyboard under the Terminal section
2. Select Control-H as the backspace key option
3. Select Session
Now it is time to connect to your JAP device.
1. Enter the IP address of the JAP device.
2. Select Telnet
3. Click Open
If Putty has an error or does not connect then you need to double check you have a static route enabled and it is properly functioning. The easiest way to test this is to enter the IP address into a web browser. If a JAP web menu does not load then the static route is not functioning
If you connected successfully then you will see a box that looks like this.
Uou can find all of the commands you will need to enter at the bottom of this page. You can copy and paste commands how ever to paste you will Right click your mouse in putty. It will then paste the text. You will need to make any changes to the command and then press enter.
In this example we are going to increase the volume for the left and right audio channel on the stereo port. The command is vol_bth_up.sh but enter has not been pressed yet.
Typically you will not get any confirmation or reply back from the JAP unit after you send a command. The example here simply shows that the audio up command was entered and now you can enter additional commands.
