MR816CSX/MR816X
*4: Check that level differences between channels
are as follows:
<2-1-2> Frequency Characteristics
Set up as in description marked
2
in procedure
<2-1-1> (P. 46).
Check that the level of each output when the
frequency is 20 Hz and 40 kHz are within the range
shown below compared with the level when the
frequency is 1 kHz.
<2-1-3> Distortion
Set up as in description marked
1
in procedure
<2-1-1> (P. 46).
Then, adjust input level so that output level is as in
the description below:
Check that the distortion of outputs is as follows:
Unit: [dBu]
* Use 22 Hz HPF and 30kHz LPF.
<2-2> S/PDIF (COAXIAL/OPTICAL) test
• Set the MR816CSX/MR816X to the S/PDIF ⇔
Analog audio connection setup for checking.
(Refer to "• Audio connection" in procedure
5-1-3-1 (P. 42))
• Connect the [S/PDIF IN] terminal and [S/PDIF
OUT] terminal to be in loop connection.
<2-2-1> Gain (MIC input)
Set up the GAIN volumes [3, 4] and [PAD] switches
as in the following table.
Unit: [dBu]
*5:Check that level differences between channels
are as follows:
* Measure only the [S/PDIF IN, OUT] (COAXIAL)
terminal.
Tolerance
2 dB or less
<2-2-2> Frequency characteristics
Set up as in description marked

* Measure only the [S/PDIF IN, OUT] (COAXIAL)
terminal.
<2-2-3> Distortion
Set up as in description marked

Then, adjust input level so that output level is as in
the description below:
Check that the distortion of outputs is as follows:
Unit: [dBu]
* Use 22 Hz HPF and 30kHz LPF.
* Measure only the [S/PDIF IN, OUT] (COAXIAL)
terminal.
<2-2-4> Gain (S/PDIF OUT)
Set up as in procedure <2-2-3>.
Measure the [S/PDIF OUT] (COAXIAL) and [adat
OUT] (OPTICAL) terminal.
Check that the output level is as follows:
Unit: [dBFs]
<2-2-5> Mute (S/PDIF OUT)
Set up as in description marked
1
in procedure
<2-2-1> (P. 46).
Measure the [S/PDIF OUT] (COAXIAL) and [adat
OUT] (OPTICAL) terminal.
Execute the Muting Circuit. (Refer to "• Muting
Circuit" in procedure 5-1-3-1 (P. 43))
Check the mute function of corresponding output
terminal according to the following table.
