The first step is to assign a name to a program. The name can be of up to 8 characters. Use the left-right keys of the
Navimec to select the position, and the up-down keys to change the letter. Once the name has been generated, press OK.
The unit will display a message to overwrite one of the available user programs, to continue press OK. Finally, with the up-
down keys of the Navimec, select the program to overwrite, and press OK to proceed, the program is stored.
REAL TIME ANALYZER (RTA)
The Real Time Analyzer module (RTA) can assist the user to verify the acoustic response of the loud speaker system. For
this module to operate, a flat-response microphone is needed connected to the input RTA MIC INPUT.
In the next menu the user will be able to adjust the level of the pink noise that is applied to the room.
MIC 70 dB (SPL)
Pink Noise: 0.0

The BPD-1 will display in MIC the sound pressure level (SPL) in dB measured by the microphone. The minimum
recommended reading to start the auto equalization is 90 dB. If the level is below 90 dB, it is recommended that the user
increase the level of the pink noise by selecting Pink Noise and pressing the left-right keys of the Navimec. For best results,
adjust the level to the level the user is planning to be using for the acoustic system during regular operation.
Once the sound pressure level has been selected, the user can proceed to the RTA by selecting the option RTA. The BPD-1
will proceed to the Real Time Analyzer (RTA) and begin to display graphically the sound pressure level at each frequency
band (as captured by the microphone). At the bottom left side of the LCD the central frequency is displayed and at the
bottom right corner the gain is given. The user can select the frequency to be displayed by using the left-right keys of the
Navimec. To exit, press the OK key.
AUTO EQ
The RTA module helps the user to calibrate the frequency response of the system in the lowest amount of time. This
module auto equalizes both inputs together. For this module to operate, a flat-response microphone is needed connected to
the input RTA MIC INPUT.
When accessing this module, the first menu will allow to adjust the Precision of the adjustment:
H (High),
M (Medium),
L (Low).
In addition, the user can select one of five possible acoustic frequency responses:
• Format 0: Flat Response
• Format 1: Bass Response (enhance the lower frequencies)
• Format 2: High Response (enhance the high frequencies)
• Format 3: Bass – Highs Response (enhance low and high frequencies)
• Format 4: Mid Response (enhance the mid frequencies)
Once the precision and response has been selected, press OK to continue to the next menu. In the next menu the user will be
able to adjust the level of the pink noise that is applied to the room.
