Mounts inside your device

To install a HELIX Extension Card it's necessary to remove the side panel of your amp and replace it with a new P SIX DSP MK2 side panel that comes with the module. HELIX includes step-by-step instructions and an installation tool to help you mount the extension card inside your P SIX DSP MK2 amplifier.

Note: Connection cables are not included — a miniUSB cable plus a device-specific adapter are required for operation. This USB connection does not support battery-charging.
