    IP Configurable EQ Adjustment, Volume Level and High/Low Pass Selection

    With the convenient web based IP Configuration utility you can easily provide independent EQ adjustments and volume levels to each individal amplifier or make adjustments to entire speaker groups. A High/Low Pass Filter setting for each channel accommodates passive subwoofers and small full range speakers. Installers can now acoustically optimize each speaker for both its type and individual location using a web browser connected via WiFi.

    Real World Power

    The Sl–1650 is a 16–channel amplifier that delivers a solid 50 watts per channel RMS into 8 ohms and 100 watts per channel RMS into 4 ohms. A dual digital power supply with a massive toroidal transformer provides the energy necessary to efficiently deliver solid, deep, controlled bass response to a house full of speakers.

    Sixteen to Eight Channel Configurable Power

    Want more power in a single zone or larger room? Each of the Sl–1650's eight adjacent speaker output pairs are configurable into a single high power output. Using the web based IP configuration utility, you can create up to eight 100 watt channels enabling the allocation of greater power to specific locations, such as more great room or outdoor applications.

    IP Configurable BusMatrix™ Selector

    A web based IP configuration utility provides control of the BusMatrix™ selector giving you the flexibility to assign each speaker channel to any of the sixteen signal inputs. Adjacent signal input pairs can also be combined and assigned to a speaker channel for mono sound applications. With BusMatrix™, routing surround sound to the master bedroom, stereo to the den and mono to the powder room is as simple as flicking a switch. BusMatrix™ makes the Sl–1650 an ideal multi–room or multi–zone amplifier and offers exciting new features and system design possibilities to the professional installer.
