Warranty Terms
NTI guarantees the MiniSPL and its components against defects
in material or workmanship for a period of from the one year
date of original purchase, and agrees to repair or to replace at its
discretion any defective unit at no cost for either parts or labor
during this period. This warranty does not cover damages caused
through accidents, misuse, lack of care, transit, the attachment
or installation of any components that were not provided with
the product, loss of parts, connecting the instrument to a power
supply, input signal voltage or connector type other than specied,
or wrongly polarized batteries. In particular, no responsibility is
granted for special, incidental or consequential damages.
This warranty becomes void if servicing or repairs of the product
are performed by any party other than an authorized NTI repair
center or if the instrument has been opened in a manner other
than specied in this manual. In case of malfunction, take - or ship
prepaid - the MiniSPL, packed in the original box, to the authorized
NTI representative in your country. Be sure to include a copy of your
sales invoice as prove of purchase date and a detailed description
of the fault. For contact-details of the NTI representative please

User Manual
How to insert the battery
• To insert the battery, press the push-pin in and slide the
sleeve off.
• Insert 1x 1.5V AA-size battery according to drawing
below. The polarity is marked on the lable inside.
• Close the MiniSPL. Turn the sleeve so that it is locked
by the push-pin.
Note: The MiniSPL does not operate without the
battery.
MiniSPL with AL1 / ML1
• Connect the MiniSPL to the AL1 / ML1.
• Approximately ten seconds later the Status-LED will
start to ash periodically indicating that the MiniSPL
has switched on.
• An empty battery will be indicated by the non-ashing
Status-LED.
• Simply unplug the MiniSPL after completed operation.
Thus the Status-LED will stop ashing, indicating it is
switched off.
MiniSPL as stand-alone mic
The MiniSPL may be operated as a stand-alone microphone
e.g. connected to a balanced audio-line, a microphone-
input or a sound-card.
Note: Follow the specied load condition to achieve the
at frequency response. Phantom power causes a lower
load condition, so make sure to switch it off.
At inputs with high DC-input resistance you may nd the
MiniSPL not switching on or the delay-time until switching
on may be too long. In this case you have to build up an
adapter according to the below circuit diagram. Please note
that both resistance ’’R’’ should be of equal values within
1% tolerance for good signal balancing.
At unbalanced inputs use pin 1 and 2. Pin 3 shall not be
connected. In this case the sensitivity will be halved.

Notes & Warnings
To avoid any problems during the operation of the instru-
ment, follow the rules listed below:
• Use the instrument for the intended purpose only.
• Never use the instrument in a wet environment.
• Remove the batteries as soon as they are at or if the
instrument is not intended to be used for a longer period
of time.
• The use of rechargeable NiCd- or NiMH-batteries is
causing shorter battery lifetime than specied.
• Note the correct polarity of the inserted battery.
• We recommend to calibrate the MiniSPL in yearly inter-
vals to fulll the specied sensitivity.
