The HTS4B is equipped with one active magnetically shielded 12″ driver mounted on the front side of a compact cabinet and two 12″ passive radiators, one on each side of the cabinet. The 400W amplifier unit is integrated in the subwoofer cabinet.
XLR and RCA line level input connectors and adjustable input sensitivity provide easy connection to all types of decoders. Bass roll-off rate and crossover phase can be adjusted to suit different acoustic environments and subwoofer positioning. A “LINK OUT” connector allows coupling of two or more subwoofers together when high sound pressure levels are required. The amplifier is equipped with an “AUTOSTART” function for automatic switching between “STANDBY” and “ON” modes. Connectors for remote power “ON/STANDBY” switches are also provided.
