MartinLogan's Dynamo 600X features a 240-watt peak-power amplifier, 10-inch audiophile grade woofer, extensive input options, optional wireless connectivity, control via a Bluetooth app, and Anthem Room Correction (AR). Dramatic bass detail and attack, superb extension, and room-shaking output ensure a compelling music and home theater experience. Dynamo 600X features left and right inputs via RCA line level as well as speaker level connections. The right input doubles as an LFE input for home theater applications. Control app for iOS and Android uses a Bluetooth connection to simplify setup and configuration of Dynamo 600X. App based controls include volume level, low-pass filter (frequency and order), phase, 20–30Hz level, three preset listening modes, and control of Anthem Room Correction. A unique tone sweep feature assists users in locating areas in listening rooms where troublesome rattles or resonances may occur. A single press of a button allows listeners to initiate a tone sweep from 20–120Hz. If a rattle or resonance occurs in the room any frequency can be held, allowing the listener to investigate and identify the source of the unwanted noise. Although correct placement plays a key role in optimizing subwoofer performance, sometimes it imposes the inconvenience of running long lengths of cable through walls, along baseboards or under floors and carpets. To solve the problem, Dynamo 600X includes a connection port for an optional wireless system. MartinLogan's new SWT-X Wireless Subwoofer System (sold separately) incorporates the latest in wireless audio transmission technology, including 2.4GHz dynamic frequency selection, forward error correction, and a range up to 50 feet. Easy to install in the subwoofer, the SWT-X receiver requires no external power source or audio connections.
