The operating controls on the NTL720 rear panel are momentary contact, “soft” switches. This means
that they control software that does the actual switching with status lights indicating the switch
“position.” Pressing a switch repeatedly will cycle through its available options.
7.3.1 INPUT SELECT
Repeatedly press the switch between the XLR input
connectors to cycle through and select the desired
input signal type. Press and hold the switch for five
seconds to bypass the user-adjustable DSP (accessible
from EAWPilot). Repeat to enable the user DSP.
LED flashing = DSP enabled
LED constant = DSP disabled
Note: U-Net can be selected with the Input Select switch, but the U-Net audio channel and routing
must be configured using the EAWPilot software application.
7.3.2 HF BOOST
Repeatedly press the HF BOOST switch to cycle through
and select the desired HF Boost option. This can be used to
compensate for high-frequency attenuation due to airloss.
Note: The EAWPilot program allows you to enter
temperature and humidity values for the system, and
listening distance values for each loudspeaker in the
array. Airloss is dependant on distance, temperature,
and humidity, and the airloss pre-emphasis is automatically calculated and applied by EAWPilot. The
factory tuning for an NTL720 is configured for a listening distance of approximately 50 ft (15 m). In
instances where EAWPilot will not be used, the HF Boost and Nearfield Contour switches can be used
to approximate the Airloss preemphasis function. The approximate listening distance associated with
each switch position is indicated in the tables.
Note: HF Boost and Nearfield Contour cannot be used together, however they can be used in
conjunction with the Airloss preemphasis function to further tailor high-frequency reponse.
7.3.3 NEARFIELD CONTOUR
Repeatedly press the NEARFIELD CONTOUR
switch to cycle through and select the desired
nearfield contour option.
7.3.4 STANDBY JUMPER
Use these dry contacts to remotely
control the operational status of the
loudspeaker’s electronics. Short the
contacts to place the amplifiers in
standby mode. This disables the high-
voltage rails powering the amplifiers,
muting the system and reducing power
consumption when the system is not
being used. Open the contacts for full
function. The Amplifier Status LED flashes red when the amplifiers are in standby mode.
Note: The NTL720 ships with the mating connector for these contacts installed. If this feature will not
be used, the connector may be removed.
