VBrick Systems VB4000, VB6000, VB5000 manual Audio Template Settings

WM Configuration

Audio Input	•	Audio Jack – Input from standard audio source. like a DVD player.
	•	Microphone DIN – Input from VBrick's AudioMate microphone.

Note: When you select Microphone DIN as the encoder Audio Input, the left audio jack input is switched off but the right audio jack input remains connected. This means that if there is an audio source connected to the right audio jack input, you can mix this input with the Microphone DIN input by setting the encoder Audio Channels value

to either Stereo or Mono (L+R).

Audio Input Level	Normal or Alternate. Default = Normal. Sets the audio level for the
	encoder audio jack or microphone input. When set to normal, the
	audio inputs accept a 4-volt peak-to-peak maximum signal. When set
	to alternate, the audio inputs accept an 8-volt peak-to-peak maximum
	signal.
Audio Gain	This setting controls the audio level of the encoder:
	• When the Audio Input Level is set to Normal, the settings are from
	49 to -53 dB and mute. Default = 0 dB. A setting of 7 is full volume
	and -53 effectively mutes the encoder. Use the high gain settings
	labeled (mic) when using a standard microphone through the Audio
	Jack inputs.
	• When the Audio Input Level is set to Alternate, the settings are
	from 12 to -48 dB and mute. Default = 0 dB. A setting of 12 is full
	volume and -48 effectively mutes the encoder.

Audio Template Settings

Note In Edit mode, the parameters affected by template settings (set in the Configuration: Encoder > Template) are shown at the bottom of the screen. These settings override the template; they do not change the template.

The following audio settings can be changed by modifying a template setting in the Configuration: Encoder > Template section of IWS. Any changes you make on this window override the template; they do not change it. See Table 11, Audio Channels: Stereo/Mono † for Bit Rate and Sample Frequency matrix.

Audio Channels	Audio Channels – The audio output mode can be configured to one of
	three possible settings:

•Stereo – Stereo directs the input left channel to the left channel in the audio stream and the input right channel to the right channel in the audio stream.

•Mono (L+R) – A combination of both the left and right channel is encoded to a single channel. The Media Player will play the audio through both speakers.

•Mono (left only) – Only the left input channel is carried in the stream. The Media Player will play the audio through both speakers.

L+R Bit Rate	See Bit Rate and Sample Frequency for all settings. The value can be
	5000–192000 bits/sec. Default = 128000. This is the audio encoding
	bit rate of the audio stream.
