Description

The DLS L1VMB is a digital voltmeter designed for demanding car audio installations. Connected directly to the same source as your amplifier, it gives you a stable and precise reading of the system voltage — in real time, without approximation.

• With the L1VMB, you instantly visualize the status of your battery and the behavior of your charging system at startup or during operation
• Its flush-mount enclosure with removable faceplate allows for a clean and tidy installation, worthy of an OEM fitment
• Secured by screws (holes at the back) or high-strength double-sided adhesive
