Figi 1: Front Panel View. This image displays the front panel of the JFA J6 Hybrid Digital Audio Processor. It features a central LCD screen for settings and monitoring, surrounded by a rotary encoder for navigation and adjustment. Below the screen are various buttons and indicators for input level, mute, limiter, and output level controls for each of the six channels. The 'LEVEL IN' and 'MAIN IN' indicators are visible on the left, while 'LEVEL OUT 5' and 'LEVEL OUT 6' are on the right, alongside the power terminal.
Figi 2: Panel aryè View. This image shows the rear panel of the JFA J6 Hybrid Digital Audio Processor, highlighting the input and output connections. On the left, there are RCA input jacks labeled 'MAIN IN'. The center features multiple RCA output jacks for OUT 1 through OUT 6. On the right, a screw terminal block is visible for power connections (BAT, REM, GND).
4. Enstalasyon ak Enstalasyon
4.1. Monte
Select a secure, dry, and well-ventilated location for mounting the JFA J6. Use the provided mounting hardware to firmly attach the unit, ensuring it is protected from vibrations and direct heat.
4.2. Koneksyon fil elektrik
Ensure all audio components are powered off before making any connections.
- Koneksyon pouvwa: Connect the power cable to the screw terminal block on the unit's rear panel.
- BAT (+12V): Connect to a fused +12V constant power source.
- REM (Remote): Connect to the remote turn-on output of your head unit or ignition switch.
- GND (Tè): Konekte ak yon pwen tè solid sou chasi a.
- Antre odyo: Connect the RCA output from your head unit or audio source to the 'MAIN IN' RCA jacks on the JFA J6.

5. Operasyon Enstriksyon
5.1. Powering On / Off
The JFA J6 will power on automatically when a remote signal is received at the REM terminal. It will power off when the remote signal is removed.
5.2. Navigasyon debaz
Use the rotary encoder and associated buttons on the front panel to navigate through the menus and adjust settings displayed on the LCD screen. Rotate the encoder to scroll through options and press it to select.
5.3. Input/Output Configuration
Access the input/output menu to configure the routing of audio signals and set individual channel parameters:
- Akeri kontwòl: Adjust the input and output gain levels for each channel to match the sensitivity of connected amplifiers and prevent clipping.
- Anviwònman kwazman: Define high-pass, low-pass, and band-pass filters for each output channel. Set crossover frequencies and slopes to optimize speaker performance and protect drivers.
- Ajisteman Faz: Adjust the phase (0° or 180°) for each output channel to ensure proper acoustic alignment with other speakers in the system.
5.4. Limiter Function
The integrated limiter protects your speakers from excessive power and distortion. Access the limiter settings to adjust the threshold and attack/release times for each channel. The 'LIMITER' indicators on the front panel will illuminate when the limiter is active.
5.5. egalizasyon
The JFA J6 offers parametric equalization for precise tonal adjustments. Navigate to the EQ menu to select specific frequencies, adjust their gain (boost/cut), and set the Q-factor (bandwidth) for each band.
5.6. Prereglaj
You can save your customized audio settings as presets for quick recall. This is useful for different music genres or listening preferences. Refer to the on-screen menu for saving and loading presets.
6. Antretyen
