The new RODE NTG-1 is a lightweight condenser shotgun microphone,
which has been specically designed for professional applications within
the lm, video, television, voice-over and ENG industries.
The NTG-1 provides an electronically balanced output stage and operates
on 48 V to the P48 standard.
The NTG-1 offers wide bandwidth and a controlled polar response coupled
with low noise SMT electronics. The NTG-1 is extremely lightweight making
it ideal for mounting directly to video cameras (with optional accessories) or
a Boom pole.
The NTG-1 comes complete with mount and windshield. The supplied windscreen effectively
suppresses wind noise when recording outdoors in moderate conditions.
Optional accessories are available for more demanding applications.

Operation
Power
The NTG-1 is designed to operate from standard P48
phantom power. The NTG-1 will operate between
44 V to 52 V applied with positive polarity to pin
2 and pin 3 via the output XLR connector.
Output Impedance
The NTG-1 will operate satisfactorily into a load impedance
as low as 1 kΩ. If a load below this is used, the output
signal level will be reduced.
The NTG-1’s output is balanced between pin 2 (hot),
pin 3 (cold) and pin 1 is ground.
