Frequently Asked Questions - AXDSPX-HK1 AXESS
What is the AXESS AXDSPX-HK1 and what does it do?
The AXESS AXDSPX-HK1 is a car audio digital signal processor (DSP). It takes audio signals from your factory or aftermarket head unit, processes them with advanced filtering, equalization, and time alignment, and sends clean, optimized signals to external amplifiers or directly to speakers. This allows you to fine-tune your car's audio system for better sound quality and staging.
How do I connect the AXDSPX-HK1 to my car stereo?
The AXDSPX-HK1 features 4 high-level speaker inputs that connect directly to your factory stereo's speaker outputs. Use the included wiring harness to tap into the speaker wires. After connecting, install the DSP between the head unit and your amplifiers. Ensure proper grounding and a solid 12V power connection for operation.
Does the AXDSPX-HK1 support Bluetooth connection?
Yes, the AXDSPX-HK1 includes built-in Bluetooth for wireless audio streaming and configuration. You can use the dedicated mobile app to adjust DSP settings, set crossovers, and control the equalizer directly from your smartphone. It also supports hands-free calling when paired with your phone.
How do I configure the DSP settings?
Configuration is done via the AXESS DSP app available for iOS and Android. Connect your smartphone to the DSP via Bluetooth, then use the app's intuitive interface to adjust EQ bands, crossover points, time alignment, and input/output levels. The app also allows saving and recalling multiple presets for different listening environments.
What are the input and output channels?
The AXDSPX-HK1 has 4 input channels (left/right front, left/right rear) and 6 output channels (front left, front right, rear left, rear right, subwoofer left, subwoofer right). This configuration supports a typical active 3-way front stage plus subwoofer, or a simpler 4-channel amplifier setup with an additional subwoofer channel.
Can I use the AXDSPX-HK1 with a factory radio?
Absolutely. The AXDSPX-HK1 is designed to work seamlessly with factory radios thanks to its high-level inputs that accept speaker-level signals. It can decode and process these signals, bypassing the factory head unit's limitations, and provide clean, full-range output to aftermarket amplifiers and speakers for a major sound upgrade.
How do I set the input sensitivity level?
The DSP features adjustable input sensitivity (2V – 8V) to match the output voltage of your head unit. You can set it via the mobile app. A general guideline is to start with the gain at its lowest setting, play music at about 3/4 volume, then slowly increase the gain until the audio is clear without distortion.
What should I do if the unit does not power on?
First, check that the power and ground connections are secure and polarity is correct. Verify that the remote turn-on signal is present (if used). If you're using signal-sensing turn-on, ensure the input signal is active. Also check the fuse in the power wire and replace if blown. If the unit still refuses to power on, contact AXESS support as the internal protection may have activated.
Is the AXDSPX-HK1 compatible with electric vehicles?
Yes, the AXDSPX-HK1 can be used in electric vehicles (EVs) as long as the 12V DC accessory system is available. EVs typically have a 12V battery for accessories. Ensure that the DSP's ground is properly connected to the vehicle chassis and that the voltage remains within 11-14.4V DC. If the EV uses an isolated audio ground, you may need to connect the ground carefully to avoid noise.
How do I adjust the equalizer and crossover?
Using the app, navigate to the EQ and crossover section. You can choose between a 31-band graphic EQ or a parametric EQ for each output channel. Set high-pass and low-pass filters with selectable slopes (12/24 dB/oct). For example, set HPF for front speakers at 80 Hz and LPF for subwoofers at 80 Hz to avoid frequency overlap and improve clarity.
What is the recommended amplifier to pair with this DSP?
Since the AXDSPX-HK1 provides up to 5V RMS preamp outputs, it pairs well with most aftermarket amplifiers that accept line-level inputs. Choose amplifiers that match your speaker system's power requirements. A 4-channel amplifier for door speakers and a monoblock for the subwoofer is a common setup. The DSP's output voltage ensures a clean signal with minimal noise.
Does the AXDSPX-HK1 come with a wiring harness?
Yes, the package includes a dedicated wiring harness that connects to the DSP. The harness has wires for power, ground, remote trigger, input signals, and output signals. This makes installation straightforward and straightforward to connect to your vehicle's wiring. Always consult the wiring diagram in the manual for exact wire colors and functions.
