Audio Input

Audio Input

Input can be from an Audio Jack (1/8" mini-phono jack) or from

 

Microphone DIN (AudioMate microphone). The default setting is

 

Audio Jack.

 

 

Audio Balance

-127 to 127. Sets audio balance between left and right channels. Zero

 

is balanced. 127 sends audio to right channel only; -127 to left

 

channel.

 

 

Audio Input Level

Hardware-dependent; not shown on all models. See Audio Gain field

 

for more details.

 

• Normal – 7 to –53 dB and mute.

 

• Alternate – 12 to –48 dB and mute.

 

 

Audio Gain (dB)

This setting controls the audio level of the encoder. It is model

 

dependent:

On models ending in –xxx0 the settings are from 3 to –60 dB and mute. The default setting is 0 dB. A setting of 3 is equivalent to full volume, -60 effectively mutes the encoder audio.

On models ending in –xxx1/–xxx2 the settings differ based on the Status: Encoder > PLX EEProm Revision number:

If the Encoder PLX EEProm Revision is 1, the settings are from 3 to –48 dB and mute. The default setting is 0 dB. A setting of +3 is equivalent to full volume and -60 effectively mutes the encoder audio.

If the EEProm PLX EEProm Revision is 2 or higher and the Audio Input Level is set to Normal, the settings are from 7 to –53 dB and mute. The default setting is 0 dB. A setting of 7 is equivalent to full volume, -53 effectively mutes the encoder audio. If the Audio Input Level is set to Alternate, the settings are from 12 to –48 and mute.

The default setting is 0 dB. A setting of 12 is the equivalent of full volume, -48 effectively mutes the encoder.

L+R Bit Rate

The transmission rate of the audio stream. If the model ends in -xxx0,

 

the transmission rate can be 192, 256 and 384 Kbps **If the model

 

ends in -xxx1/-xxx2 the audio bit rate can be 256 or 384 Kbps.

 

 

Sample Frequency

Frequency at which the audio is sampled at the encoder. If the model

 

number ends in -xxx0, the sampling rate can be 44.1 KHz or 48 KHz.

 

If the model number ends in -xxx1/-xxx2 the sampling frequency is

 

48 KHz.
