10. Cord Clamp
Pinches and securely holds the AC adapter cord to
prevent its plug from detaching.
11. DC Power Input Terminal [DC INPUT]
A 24 V DC input.
12. Functional Earth Terminal [SIGNAL GND]
Hum noise may be generated when external
equipment is connected to the unit.
Connecting this terminal to the functional earth terminal
of the external equipment may reduce the hum noise.
Note: This terminal is not for protective earth.
13. AC Adapter Terminal
[NX-100: AC ADAPTER, NX-100S: DC INPUT]
Connect the AC adapter* to this terminal.
* Use the AD-246 (optional) or its equivalent.
14. Network Connection Terminal [10/100M]
Connects to 10/100 Base-T networks. (RJ-45 Ethernet
jack)
15.RS-232C Terminal
A 9-pin D-sub connector (male).
16. Control Output Terminal [CONTACT OUTPUT]
An open collector output (Withstand voltage: 30 V DC,
Control current: 50 mA maximum).
17. Control Input Terminal [CONTACT INPUT]
A no-voltage "make" contact input (Short circuit
current: 10 mA, Open voltage: 12 V).
18. Audio Output Terminal [AUDIO OUTPUT]
A 0 dB*/10 kΩ balanced output. Line level audio signal
output.
H: Hot
C: Cold
E: Ground (shield)
19. Audio Input Terminal [AUDIO INPUT]
A –58 to 0 dB*/2 kΩ balanced input. Microphone or
line level audio signals can be connected to this
terminal.
H: Hot
C: Cold
E: Ground (shield)
20.Input Volume Control [INPUT VOLUME]
Adjusts the audio input level.
Turn the control clockwise to increase the level and
counterclockwise to decrease it.
Adjust the control so that the Input signal indicator (3)
lights and the Input peak indicator (4) does not light.
21. Input Level Selection Switch [LINE/MIC]
Set this switch to the MIC (right side) position when
using a microphone, and to the LINE (left side) for
other inputs. (Factory-preset to the LINE position.)
22. Phantom Power ON/OFF switch [PHANTOM]
The supply voltage is 24 V DC.
To supply the phantom power to the microphone
connected to the Audio input terminal (19), set the
Input level selection switch (21) to the MIC position
and the PHANTOM switch to the ON position.
* 0 dB = 0.775 V
