Processor Overview

• RCA signals input: Input for low-level/high impedance (RCA) signals.
• WIRE High-Level Input: Input for high-level / low-impedance signals (from the speaker output of the players or multimedia centre).
• It features the function of automatic turn-on by the input signal, so it eliminates the use of the REMOTE-IN wire from the power connector when using this input.
• Note: The system is designed for use in virtually all multimedia head units on the market.
• However, on some head units, you may not get the trigger effect due to the type of audio output circuit. In this case, use the REMOTE wire to trigger it normally.
• Input clip indicator LED: It shows that the signal is reaching the maximum limit of the processor input, which causes signal distortion. If it comes on, reduce the volume of the signal source and readjust the system gains accordingly.
• Limiter/clip LEDs: They have a dual function: They indicate that the signal from that output has reached the maximum level (when the limiter is off) or the actuation of the limiter (when the signal reaches the threshold defined in the limiter).
• Power connector:

Screens & basic operation

INITIAL SETUP: When turned on for the first time, the processor waits for the language to be set. Choose the desired language and confirm with a quick touch in the center of the encoder.

• Turning the encoder knob (clockwise or counterclockwise) adjusts the master volume (Input volume).

Output selection keys

• Quick touch (Click) on the key of each output(1 to 4) It performs an adjustment of the individual gain in each output.

• Individual mute: Press the output key (1 to 4) for 1 second until the key goes out. To unmute the individual sound, press it again for 1 second.

• Quick click on the center of the encoder, to access the MAIN MENU and its functions.

• Long touch (1 second) in the center of the encoder returns to the previous menu, until returning to the main screen.

Menu & parameters navigation

Use the encoder, turning left (decrement) or right (increment). Menu selection, option or parameter change can be done by pressing the centre of the encoder.
Note: In any of the audio adjustment screens, the hotkeys for channels 1 to 4 allow you to check and adjust the parameters of each channel without leaving the desired option
Tip: To fine-tune a parameter or increment/decrement the number after the decimal point, rotate the encoder slowly. E.g., in the signal level (dB) adjustments, the increment will be 0.1dB when turning the encoder slowly, and 1B when turning it more continuously and quickly.

Menu structure & Description

• Press the encoder button (center–long press) to back to Main Screen.

Audio menu: Adjusts and controls related to audio processing:

I/O Routing: Defines the internal connections between outputs and inputs. Available options: A, B or A+B (sum of the two inputs).
E.g.: setting the OUT 1 output to A, its signal will come from input A.

Band equalizer: It has 5 filters of equalization, with attenuation /boost of up to 12dB, adjustable Q factor, 2 octaves, but centre frequencies which can be changed up to 2/3 octave.
Acts simultaneously on inputs A and B.
The Pro 2.4D has 12 preset equalization curves, selectable in MAIN MENU > Presets EQ.

Crossover: Set the high pass (HPF) and low pass (LPF) filters of the selected output way. The cutoff frequencies could be set from 10Hz to 22KHz, and are available some kinds of filters (Butterworth, Bessel, Linkwitz Rilley) in different slopes (-6, -12, -18, -24, -30, -36, -42 e -48dB/ Octave).

Delay: Set the delay to be applied to the audio signal, for systems alignment. The position of the transducer’s voice coil should be taken in account to set the optimal delay value.

• Rotate the rotary encoder to set the delay amount to be applied.

The voice coils of each transducer aren’t aligned inside the acoustic box, so there is some delay that can degrade the perfect audio playing. The Delay feature applies different delay amounts for each output way, to get the perfect audio alignment.

How to set the delay parameter value (centimetre)

1. Set the reference coil (*) farthest from the box panel (in our example, the reference was the centre of the horn coil)
2. Measure the other channels and find the measure A. Set the closest measurement (in cm) for each channel.
3. Repeat the procedure for the other channels (the channel selection can be done through the keys of each channel).

Phase: Allows inverting the phase of the channel output signal, selecting option [180]. Select the channel using the OUT1 to OUT4 selection keys and select the desired phase by turning the encoder.

• Limiter: Acts as a limiter for the maximum signal level of the processor output, so as not to exceed the power limit supported for each system transducer.

Limiter in RMS function

• Limiter that acts with reference to the RMS value of the audio signal, prevents overheating of the speakers due to excessive power.

Limiter parameters

Modes: MANUAL = Manual Attack, Hold and Release adjustment; AUTO: Sets the Attack, Hold and Release parameters automatically, according to the channel frequency cutoff (HPF).

• Threshold – Point when the limiter begins to act (indicated by the RED LED on each lane turning on). To turn off the limiter, turn the encoder clockwise until [OFF] appears in the threshold value.
• Attack, or Attack time – Time needed to limiter reduce the gain after the signal reaches the threshold.
• Hold – Time that the limiter keeps the signal attenuated even after its level drops below the threshold.
• Modes: MANUAL = Manual Attack, Hold and Release adjustment; AUTO: Sets the Attack, Hold and Release parameters automatically, according to the channel frequency cutoff (HPF).
• Limiter: Acts as a limiter for the maximum signal level of the processor output, so as not to exceed the power limit supported for each system transducer.
• Rel e ase, or Release time – Time needed to limiter return to the original gain after the signal drops below the threshold.

According to Threshold selected. The accuracy of this measurement depends on the signal frequency as a function of the Attack time. At low frequencies, very fast attack times can affect measurement accuracy.

Limiter in PEAK function

• Limiter that acts with reference to the PICO value of the audio signal, prevents mechanical damage and overheating of the speakers due to excessive displacement.

Limiter parameters

• Modes: MANUAL = Manual Release adjustment; AUTO: Sets the Release parameter automatically, according to the channel frequency cutoff (HPF).
• Dynamic – Point when the limiter acts (indicated by the lighting of the RED LED on each channel) with reference to the peak value of the signal in relation to the threshold dened in the RMS limiter (Music Dynamics).
• Hold – Time that the limiter keeps the signal attenuated even after its level drops below the threshold (Dynamic).
• Release, or Release time – Time needed to for the limiter to return to the original gain after the signal drops below the threshold.

Output level: Defines the level of each output channel, allowing to apply from -45dB attenuation up to +15dB gain, regardless the main volume. Select the output channel using the selection keys (1 to 4), adjust the gain level by rotating the encoder.

Note: This function has a shortcut: simply pressing the corresponding output key when in the main screen.

Output parametric EQ. : EQ with 1 band and adjustable parameters for:

• G = Filter gain/attenuation (-12dB to +12dB)
• F = Filter central frequency, adjustable from 10Hz to 22KHz
• Q = Filter width adjustment from 0.4 (widest) to 10.0 (narrowest)

• Audio Generator : Sine wave generator, with frequency and variable amplitude. With 4 modes:
• Fixed Frequency : Sine generator with frequency (10Hz to 22KHz) and amplitude (-60dB to 0dB) adjustments. Note that when activating the generator, the signal is sent to all outputs and it is possible to adjust the other functions and parameters in real time, since the generator remains active and defined as a signal source when in the ON position, even when accessing another function.

• The voltage level shown is informative and may differ depending on processing settings (Equalization, cuts, limiter, etc…).

Sweep (Slow / Medium / Fast): It performs a signal sweep, with the initial and final frequency defined by the user, which remains in a continuous cycle (repeating) until the generator is turned OFF. There are 3 sweep speeds avaliable.

• Language: Choose the desired language (Portuguese, English or Spanish)

• Save config: Allows you to choose the memory location and assign a convenient name to these settings. Selecting which memory location, click on the encoder center to switch to the text. Rotate the encoder to select the desired letter, click on the center of the encoder to move to the next character. To erase, rotate the encoder until “<” + quick touch on the center of the encoder. To finish editing and save the memory name, place the cursor after the last character + long press on the center of the encoder and confirm “YES”.

• Load config: Load a previously saved configuration or the factory default setting. Rotate the encoder to select the desired memory, click on the center of the encoder to select and then confirm. Important: when you select the FACTORY SETTINGS option, the previously saved settings will be lost.

• Password / lock: Allows you to lock the processor using a password (the default password is 1234) or change the password to a personalized one, with 4 digits.

NOTE: When locking the processor, a padlock icon will appear in the upper right corner of the screen. A password will be required to access the settings. To reset the processor to factory settings without accessing the menu (e.g. due to lost/forgotten password), just turn on the processor while keeping the keys of ways 1 and 2 and the center of the encoder pressed simultaneously. This will erase the contents of user settings memories and reset the product to initial setup.
