MR816CSX/MR816X
<2-7> Crosstalk (OUTPUT 1 – 8)
Set up as in description marked
1
in procedure
<2-1> (P. 44).
Then, adjust input level so that output level is as in
the description below:
Unit:[dBu]
* Turn ON the [PAD] switches of INPUT channel 1 – 8.
*2: Connect 150 Ω resistor to the input terminals as
follows:
MIC/LINE INPUT CH 1 ‒ 8:
Between pin 2 (Hot) and pin 3 (Cold)
Measure the output level at the [OUTPUT 2 ‒ 8]
terminals.
Check that the noise levels are as follows:
Unit: [dBu]
* Use 22 Hz HPF and 30 kHz LPF.
<2-8> Crosstalk (Headphones 1, 2)
Set up as in description marked
3
in procedure
<2-1> (P. 44).
Then, adjust input level so that output level is as in
the description below:
Unit:[dBu]
* Turn ON the [PAD] switches of INPUT channel 1 – 4.
*3: Connect 150 Ω resistor to the input terminals as
follows:
MIC/LINE INPUT 1 ‒ 4:
Between pin 2 (Hot) and pin 3 (Cold)
Measure the output level at the Headphones [1, 2]
terminals.
Check that the noise levels are as follows:
Unit: [dBu]
* Use 22 Hz HPF and 30 kHz LPF.
<2-9> Mute
Set up as in description marked
1
and
3
in
procedure <2-1> (P. 44).
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.
Unit: [dBu]
* Use 12.7 Hz, -6 dB/oct LPF.
<2-10> INSERT I/O
Set up as in description marked
2
in procedure
<2-1> (P. 44).
Insert a plug, which has wiring connection as in the
following fi gure, to the [INSERT I/O 1, 2] terminal
to be measured.
Check that the level at the [OUTPUT 1, 2] terminal
is as described below.
