Selection Advice The DVR2000E is Marathon’s only digital AVR with microprocessor control. The key advantage of digital is long-term stability — analog AVR potentiometers drift over time (may need recalibration after 2-3 years), while digital auto-calibrates. If the customer requires long-term maintenance-free operation, the DVR2000E is worth the $50-70 premium.
