CONFIGURING THE SOUNDSTATION VTX1000 FOR AUDITORIUM USE
INTRODUCTION
The VTX 1000 is normally used in conference rooms, but it can be adapted for a wide
variety of settings. One of these is the large auditorium, where you occasionally want the
audience to listen to a phone call from someone on stage.
There are three main steps in setting up in an auditorium: train the audio engineer, set up
and test the system, and train the presenter.
STEP ONE: TRAIN THE AUDIO ENGINEER
It’s best if the audio engineer reads this note before beginning to set up, because the VTX
1000 doesn’t work the same as other audio systems. Here are a few key points:
¾ The VTX 1000 has built-in AGC, noise reduction, gating, adaptive filtering,
and other functions. These cannot be disabled; they’re essential to its
working correctly.
¾ Only use filters if needed, not reverb, limiters, or other dynamic effects.
¾ Place a couple of test calls during the setup to get the levels just right.
¾ Don’t “ride” the levels during the call. Leave them alone.
¾ Keep gains to the lowest that's acceptable.
STEP TWO: CONFIGURE AND TEST THE SYSTEM
1. SET UP THE VTX 1000
You are going to replace the VTX 1000’s internal microphones and speaker with
external microphones and speaker.
a. ENABLE THE EXTERNAL INPUT.
AUDIO SETUP -> AUX INPUT), change the function of AUX IN to ON by pressing
ON, then SAVE (remember to press SAVE!)
b. ENABLE THE EXTERNAL OUTPUT.
AUDIO SETUP -> AUX OUTPUT), change the function of AUX OUT by pressing
EXT SPEAKER, then SAVE.
