Frequently Asked Questions - P SIX DSP Ultimate Helix
How do I connect the Helix P SIX DSP Ultimate to my car stereo?
Connect the high-level inputs to your factory speaker outputs, or use the optical/coaxial inputs for a digital source. Then connect the RCA outputs to your amplifiers.
Can I tune the DSP using my smartphone?
Yes, the Helix PC-Tool software allows full DSP tuning. For mobile control, you need the optional Helix WIFI module.
What is the maximum power output per channel?
The rated power is 80 W RMS per channel at 4 Ω. At 2 Ω, output increases but ensure adequate cooling.
Does the unit support Bluetooth audio streaming?
The P SIX DSP Ultimate does not have built-in Bluetooth. You can add an external Bluetooth receiver via the AUX input.
How do I update the firmware?
Download the latest firmware from the Helix website, connect the unit to your PC via USB, and use the PC-Tool software to update.
What is the purpose of the time alignment feature?
Time alignment compensates for the different distances from each speaker to the listening position, creating a centered soundstage.
Can I use the unit with a factory head unit?
Yes, the high-level inputs are designed to accept speaker-level signals from most factory radios without needing a line output converter.
How do I reset the DSP to factory settings?
Press and hold the reset button (located near the input selector) for 5 seconds using a paperclip, or use the PC-Tool software to load a default preset.
What type of power supply is required?
It requires a 12 V DC power source from the car’s electrical system. Use a fused power wire (recommended 15A fuse) connected to the battery.
Is the unit compatible with 2 Ω speakers?
Yes, the amplifier is 2 Ω stable, but ensure proper ventilation as the unit will run hotter at lower impedances.
