This method allows your main speakers to receive a high-pass filtered signal (not full range), and the subwoofer to be utilized for low-to mid-bass reproduction. The full-range line-level signal coming from the receiver’s “Pre-Out” passes through the SubOne i Controller’sselectable high-pass filter, which removes the low frequencies from the signal before sending it back to the receiver’s “Main-In.” Thisconfiguration effectively increases the receiver and speakers’ dynamic range and power output by sparing them the difficult task of repro-ducing low frequency information.1) Your L & R speakers are connected directly from your amplifier / receiver.2a) If you have a receiver with “Pre-Out” and “Main-In” jacks, patch in the SubOne i Controller between these. With an RCA intercon-nect cable, connect the receiver’s “Pre-Out” to the SubOne i Controller’s LINE IN. Connect a second RCA interconnect cable from theSubOne i Controller’s SATELLITE LINE OUT back to the receiver’s “Main-In.”2b) If you have a separate preamplifier and main amplifier, connect the preamplifier output to the SubOne i Controller’s LINE IN.Connect a second interconnect cable from the SubOne i Controller’s SATELLITE LINE OUT to the main amplifier’s line-level inputs.With this configuration, your preamplifier is not connected directly to your amplifier; instead the signal passes through the SubOne iController before it reaches the amplifier.3) Connect the SubOne i Controller’s SUBWOOFER OUTPUT to the SubOne i input terminal with the supplied RCA cable.4) See page 6 for instruction on using the LFE Input and LFE Gain controlConnect the SubOne i Controller between a receiver’s “Pre-Out” and “Main-In”,with high-pass filter loopUse if:You wish to send your L & R speakers a high-pass filtered signal and/or LFE signalYou have a receiver with “Pre-Out” and “Main-In” jacksYou have a separate preamplifier and main amplifierS u b O n e i C o n n e c t i o n M e t h o d # 18SubOne i Connection Method #1
