PCM and NonPCM
Linear PCM audio
indicates raw and uncompressed digital audio data, which is encoded
from analog audio signals using the Linear Pulse Code Modulation (LPCM) method.
NonPCM (non-linear) audio
indicates digital audio data other than linear PCM audio and
includes compressed audio streams such as Dolby E or AC3.
IMPORTANT
Note that some audio channels may be output improperly if PCM and non-PCM or
non-PCM of different-format audio channels are included in a group.
6-1-4. ANALOG INPUT LEVEL
Parameter
Channel
Default
Description
ANA LVL
CH1/2 to 7/8
+4dB
Sets the ANALOG audio input level on a
per-channel pair basis. (UFM-3MUXAI required)
See section 8-2. "Digital Output Level versus
Analog Input Level" for details on audio output
level settings.

20dB, -10dB, -4dB, 0dB, +4dB, +8dB, +10dB
* Analog audio impedance and balance/unbalance can be selected using jumpers on the
UFM-3MUXAI front module. (See section 8-1. "UFM-3MUXAI FRONT CARD.")

Default
Description
SDI Gain
CH1 to 16
0.0dB
Adjusts the input gain for each embedded, AES
and analog audio channel.
Gain adjustment cannot be performed for
non-PCM audio channels. (See section 6-1-3.)

Default
Description
SDI MAP
CH1 to 16
Same
as SDI
IN.
Assigns audio input channels to output channels.
Basically, audio assignments can be performed
on a per-channel basis, however, asynchronous
(non-PCM) audio must be assigned on a
per-group basis.
Available audio channels are:
SDI CH1 to 16
AES CH1 to 8
ANA CH1 to 8
(UFM-3MUXAI required)
SDI GRP1 to 4
