10. The Setup Files box should contain a list of all PCAP II Plus setup files on your hard disk.

The installation procedure in Section 2.2: should have installed several setup files which have

the .DAC extension onto your hard disk. Included in these setup files are:

File Description

PHONE.DAC “Landline” telephone audio enhancement

GSMBUZZ.DAC GSM mobile phone RF interference noise reduction

BODYWIRE.DAC “Body wire” receiver static noise reduction and voice enhancement

MOTOR.DAC Motor/engine noise reduction

HUM60HZ.DAC Powerline hum and buzz removal (North America)

HUM50HZ.DAC Powerline hum and buzz removal (all countries outside North

America)

JAILCELL.DAC Cancellation of severe room echoes and reverberations (e.g., jail cell)

RADIOTV.DAC Cancellation of radio and/or TV audio from live or recorded audio

using a reference

These basic setups should be able to improve the voice quality of most typical law-enforcement

recordings. To begin processing audio with one of these setups, open the desired setup file by

clicking on its filename in the Setup Files box, then click on OK.

11. When the mouse cursor returns to normal, the setup file opening will be complete. Toggle the

MONITOR switch on the external processor between INPUT and OUTPUT to hear the

difference between the unprocessed input signal and the processed output signal (again, the

MONITOR INPUT selection does not function when you are using the DIGITAL input).

Feel free to experiment with the PCAP II Plus Master Control Panel settings – the settings loaded from

the setup file can usually be tweaked by the user to improve the processed result. Remember - you can

always go back to the original setup at any time by repeating steps 8-12. Also, any setup you create

can be saved for later reuse by clicking File, then Save Setup File. Or, if you wish to try loading any of

the other basic setup files, simply repeat steps 8-11 and select a different file.

Once you become comfortable recalling the basic setup files, you are encouraged to complete the

PCAP II Plus Tutorial in Section 3.2: .
