Setup
Unpacking
Carefully remove the Zapco HB-46-ADSP amplifier from its packaging. Inspect the unit for any signs of damage during transit. Retain all packaging materials for future transport or storage.
Mounting
The HB-46-ADSP is designed for surface mounting. Choose a secure, dry, and well-ventilated location for installation, away from direct heat sources or excessive vibration. Ensure adequate space around the unit for proper airflow and cable management. Use appropriate screws or fasteners to secure the amplifier firmly to the chosen surface.
Wiring Connections
Before making any connections, ensure your vehicle's battery is disconnected to prevent electrical shorts. The HB-46-ADSP operates on a 12 Volts DC power supply.
- Power Connection: Connect the main power cable (B+) to the positive terminal of your vehicle's battery, ensuring an inline fuse is installed close to the battery. Connect the ground cable (GND) to a clean, unpainted metal surface on the vehicle chassis.
- Remote Turn-On: Connect the remote turn-on wire (REM IN) from your head unit or ignition source to the amplifier's remote input. This will turn the amplifier on and off with your audio system.
- High-Level Inputs: For OEM integration, connect the speaker outputs from your factory head unit directly to the 4-channel high-level input connector on the amplifier. Ensure correct polarity.
- RCA Inputs: For aftermarket head units, connect the RCA pre-out cables from your head unit to the 2-channel RCA inputs (AUX R, AUX L) on the amplifier.
- RCA Outputs: If expanding your system with additional amplifiers, connect RCA cables from the 6-channel RCA outputs (CH1-CH6) to the inputs of the external amplifiers.
- USB Connection: Use the AUDIO USB port to connect the amplifier to a PC for DSP software configuration.
Operating Instructions
Powering On/Off
The amplifier will power on automatically when a remote turn-on signal is received from your head unit or ignition. It will power off when this signal is removed.
Audio Input Selection
The HB-46-ADSP automatically detects the active input source (High-Level or RCA). For Bluetooth streaming, ensure no other wired input is actively playing, and pair your device as described below.
DSP Software Usage
The full potential of the HB-46-ADSP is realized through its DSP software. Connect the amplifier to a PC via the AUDIO USB port or use the mobile app via Bluetooth. The software provides access to:
- 15-Band Equalizer: Adjust the frequency response for each channel independently to fine-tune your audio.
- Crossover Settings: Configure high-pass, low-pass, and band-pass filters for each channel.
- Time Alignment: Adjust the delay for each speaker to ensure sound reaches the listener at the same time.
- Gain Control: Set input and output gain levels for optimal signal matching.
- Phase Control: Adjust the phase of individual channels.
Refer to the dedicated DSP software manual (available for download from Zapco's official website) for detailed instructions on using all DSP functions.
Bluetooth Streaming
To stream audio via Bluetooth 5.1:
- Ensure the amplifier is powered on.
- On your mobile device, enable Bluetooth and search for available devices.
- Select "Zapco HB-46-ADSP" (or similar name) from the list to pair.
- Once paired, you can stream audio from your device to the amplifier.
Music Player Functionality
The integrated music player allows playback of high-quality audio files directly from a connected USB drive or via the mobile app. Supported formats include MP2, MP3, MP4, WMA, APE, FLAC, AAC, M4A, WAV, AIF, and AIFC. Use the mobile app to browse and control playback of your music library.
Maintenance
Cleaning
To maintain the appearance and performance of your amplifier, periodically wipe the exterior with a soft, dry cloth. Do not use harsh chemicals, solvents, or abrasive cleaners, as these can damage the finish or internal components. Ensure the unit is powered off before cleaning.
Storage
If the amplifier will not be used for an extended period, disconnect it from the power source. Store it in a cool, dry place, away from direct sunlight and extreme temperatures. It is recommended to store the unit in its original packaging to protect it from dust and physical damage.
