You can load your own audio files onto the CF-Card and replay with the

Do not delete the calibration data file labeled “xxx.cal“!
The NTi Audio TalkBox requires the calibration data to meet the product specifica-
tions. A back up copy of the calibration data is on the NTi Audio TalkBox CD en-

File name format
The first character of the wav-file name matches the output selector switch posi-
tion. So the audio files names are e.g. “nr_anyName.wav”, whereby “nr” is the Talk-
Box selection switch position and “anyName” describes the content of the wav-file
for example “9_myfile1.wav” or “A_myfile2.wav” - “F_myfile3.wav”. The maximum
length of the filename (=anyName) are 8 digits.
Level
The test signal level shall be physically tested by using an NTi Audio Acoustic Ana-
lyzer and the source data adjusted to requirements.
Length
The minimum length of your wave file is 100ms.
