6.10.1 ANALOG SIGNAL INPUT CONNECTION
The two XLR-type input connectors on the rear of each NTS250, one female and one male, are
designed for professional audio signal levels, nominally 0 dBu (= 0.775 V). Normally, use the female
XLR as the signal input. Use the male XLR as a loop-thru output to connect the same signal input to
additional NTS250s.
To use these connectors for analog audio input signals, repeatedly press the associated momentary
INPUT SELECT switch, cycling through the LED indications until only the NORM/ANALOG LED is
illuminated.
Cable: 2 conductor plus shield
Mating Connector: XLR-3 male
PIN 1 Shield
PIN 2 Plus / Hot
PIN 3 Minus / Cold
6.10.2 DIGITAL SIGNAL INPUT CONNECTION
The two XLR-type connectors used for analog audio signals are also used for digital audio signals.
These are designed for the AES/EBU digital signal (AES3 Standard). Use the female XLR as the signal
input. Use the male XLR as a loop-thru output to connect the same signal input to additional NTS250s.
To use these connectors for digital audio input signals, repeatedly press the associated momentary
INPUT SELECT switch, cycling through the LED indications until either the AES/EBU Ch 1 or the
AES/EBU Ch 2 LED is illuminated.
Channel 1 and Channel 2 are also referred to as Subframe 1 and
Subframe 2.
Cable: 2 conductor plus shield
Mating Connector: XLR-3 male
PIN 1 Signal earth (shield)
PIN 2 Signal
PIN 3 Signal
IMPORTANT: Looping an AES/EBU signal to another NTS250 or other audio device’s analog
input will result in audible noise at potentially high levels. Make sure the downstream service
input accepts an AES/EBU (AES3) digital input signal.
6.10.3 USB CONNECTION
The standard USB connection on the rear of the NTS250 is designed to connect a
computer with the EAWPilot control program installed. Subsequent NTS250s are
connected using the U-Net ports. EAWPilot provides user-adjustable control over
individual elements in the array and over the array as a whole.
