3. If you choose to use battery power, a 9 Volt (PP3)
battery should be fitted into the cavity within the
microphone body ensuring correct polarity (+ to +
and - to -). We recommend that you use a high
quality alkaline battery. To fit the battery, simply un-
screw the lower section of the body and insert the
battery into the cavity (terminals first). Secure the
battery in place with the flexible spring clip and re-
assemble the body, screwing the sections firmly
together.
4. The ON/OFF switch turns the microphone ON or
OFF when powered by either phantom or battery.
When using battery power, the switch should be
switched to OFF when the microphone is not in use. If
left ON, the battery power will be unnecessarily
depleted. We recommend that during long periods of
non-use, the battery should be removed, as it may
leak, and that could damage your NT3.
When the NT3 is switched ON, the red battery status
L.E.D. (light-emitting-diode) gives an indication of
battery power and should always be carefully
observed. When the L.E.D. flashes (illuminates for
about 1 second), the battery power is ‘good’. If the
L.E.D. remains illuminated significantly longer, the
battery should be replaced. Tests have shown a life
expectancy for a high quality alkaline battery used in
the NT3 to be in excess of 400 hours.*
*NOTE: This is equal to 8 hours recording per week for a
year (including 2 weeks holidays!!!)
5. The NT3 may be connected direct to a mixer
(recording or live) and battery power will only
be required if the mixer does not have an in-
built phantom P48 supply. Connection may
also be made direct to a portable DAT or
other tape machine enabling field/location
operation using the 9V battery supply.
