    Full text manual (for reference)

    The NV-SUBAMP100-xx is a compact, wall-mountable 100-watt digital subwoofer amplifier from Nuvo (Legrand), designed to add stand-out bass response to any audio system. It pairs with the optional NV-SUBIC8 passive in-ceiling subwoofer for a discreet, space-saving low-frequency solution.

    Key Features

    • Powerful, compact, all-digital subwoofer amplifier ideal for small to medium-sized audio installations
    • Installation-friendly wall-mountable design
    • Unfiltered LFE (low frequency effects), RCA, and speaker-level inputs
    • EQ settings for use with any Nuvo passive in-ceiling or in-wall subwoofer
    • Signal-sensing power ON/OFF — automatically activates when it detects a signal, returns to standby after ~15 minutes of silence
    • Variable crossover and phase adjustment to match subwoofer output with main speakers
    • Convenient power connection for an optional wireless receiver
    • Two-year warranty

    Compatible Subwoofer

    One or two NV-SUBIC8 in-ceiling subwoofers may be used with a single NV-SUBAMP100-xx (wire subwoofers in parallel when connecting two units to one amplifier). The NV-SUBIC8 uses a discrete, infinite-baffle design for maximum placement flexibility, ships with a round magnetic grill, and offers an optional square magnetic grill (NV-RGIC8-SQR).
