Mic Test

To test the SoundStation VTX 1000’s microphones from within the Mic Test portion of the Diagnostics section, highlight the microphone you wish

to test, and then press the SELECT button. The microphones are numbered according to the diagram below:

MIC 1

MIC 4

MIC 2

When you have selected a microphone:

That microphone’s LED will light up red.

That microphone will begin sampling at a 1 Hz rate, 50% duty cycle.

The display will show a meter that modulates according to the relative sample received by that microphone.

SoundStation VTX 1000 Operation Manual

Console Speaker Test

From the Console Speaker Test portion of the Diagnostics section, you can select an acoustic test signal to drive through the SoundStation VTX 1000’s speaker for speaker testing and to sample the room acoustics.

Highlight the desired signal, and press the SELECT button soft key to activate the signal.

Sine Sweep is a test signal consisting of a 100 Hz to 14,000 Hz sine wave whose frequency is swept according to a linear progression of frequency as a function of time, or (t)=A*sin(kt).

One kHz Tone is a constant tone generated at exactly 1000 Hz.

White Noise is a signal whose energy is distributed uniformly among all frequencies within a band of interest, which for the SoundStation VTX 1000 is 100 Hz to 14,000 Hz.
