SAT SUB OUT H Slave OUT Subwoofer The BM9S II provides two different signal inputs Owner s manual Before operation LFE Slave IN This input allows the LFE Low Frequency Effect channel to be connected The signal is reproduced by the subwoofer routed to the Slave OUT for a second subwoofer to be connected The SUB Lowpass control has no impact on this input SAT SUB IN This input allows the connection of a full bandwidth signal The signal is reproduced by the subwoofer routed to the SAT SUB OUT terminals Low frequencies are cut off according to the SAT Highpass setting routed to the Slave OUT for a second subwoofer to be connected High frequencies are cut off according to the SUB Lowpass setting Before operation Connecting a single subwoofer 1 Connecting as LFE channel Connect subwoofer to LFE Slave input 2 Connecting as subwoofer for satellites Connect full bandwidth signal to SAT SUB input Sub re produces sum of right and left signal Set the Mode switch to LFE Notes You can also use both connection types The signals will be combined in the BM9S II and routed accordingly This allows the BM9S II to reproduce both the LFE channel in formation as well as the bass range of the connected sat ellite system Use Slave mode if you want to use an external bass man agement system Multiple subwoofer connections
