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.
