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 specied,

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 specied 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 specied 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 specied.

• Note the correct polarity of the inserted battery.

• We recommend to calibrate the MiniSPL in yearly inter-

vals to fulll the specied sensitivity.
