The Hertz DRC HE is a digital remote control for the Hertz H8 DSP 8-channel digital signal processor, giving dash-mounted control of volume, balance, fader, and subwoofer level, switching between two tuning presets saved from the PC software, and selection of the master, auxiliary, or optical digital input - all without connecting a computer. It is sold as a single unit and connects to the H8 DSP with the provided 4.5 m (177 in.) AC Link control cable.After the H8 DSP is tuned once from a PC, the DRC HE becomes the day-to-day interface: mount the compact 63 mm x 36 mm x 12 mm (2.48 x 1.4 x 0.47 in.) controller in an ergonomic spot on the dashboard and manage the whole system from the driver's seat. Switching between the two stored tuning memories lets you flip between, for example, a driver-focused stage and a whole-car setting instantly.What's Included 1 x DRC HE digital remote controller AC Link control cable, 4.5 m (177 in.) Sold as a single unit.CompatibilityThe DRC HE is designed for the Hertz H8 DSP processor and plugs directly into its dedicated remote (AC Link) port. It is not a universal remote: it does not control head units, amplifiers, or other DSP models. Note that the Hertz H8 DSP DRC package already includes this remote - buy the DRC HE separately only if you have the standalone H8 DSP or need a replacement.
