Rear Panel Connections
Figure 1 shows the connections on the rear panel of the CHT-R.
Following are brief descriptions of the connections described in Figure 1. More detail on these connections can be found on the next page.
(1)LOW-PASS CROSSOVER
Use this knob to select the high-frequency range at which you wish to cut off the signal to the subwoofer. When the knob is turned all the way to the left, the Subwoofer Direct feature is invoked and the subwoofer plays all frequencies up to 200 Hz.
(2)VOLUME Control
This control allows you to balance the output from the subwoofer to the main speakers in your system. This control should be set to achieve similar volume level from between both the main speakers and subwoofer. When pressing volume up or down, the speed at which the power light blinks indicates subwoofer volume - the faster the blinking, the louder the unit plays.
VolumeNote:is also controllable by using the supplied remote.
(3)AUTO ON/OFF Switch
Use this switch to select between auto-on (active) and constant on (inactive) operation.
(4)LINE OUTPUT

(5)LINE INPUT/LFE Input
Connect these jacks to the LINE OUT preamp output, LFE output, or subwoofer output jacks of your receiver/processor. If using the LFE output from your receiver or processor, plug the single cable into ”theL “LFE– input or, for more signal, use a” Y “ connector and feed the sig”nLalputs“into. bothand”R “

(6)HIGH PASS CROSSOVER Switch
This switch selects the frequency for the high pass crossover. This crossover is functional on both line and speaker-level outputs. Smaller speakers with limited low frequency output may perform better using the higher 100 Hz setting that will reduce the low frequencies sent to them. Larger speakers with greater low frequency output may be able to handle the 80 Hz setting without strain.
(7)SPEAKER LEVEL INPUT Terminals
Connect these input terminals to the speaker output terminals of your amplifier or receiver. If you use this method of connection, when you go to the receiver speaker set up menu, make sure you select the large speaker option.
(8)SPEAKER LEVEL OUTPUT Terminals
Sends a crossed-over speaker-level signal to the front speakers. See below for a more detailed explanation of this crossover.
Rear Panel Connections – Detailed Explanation
Your new subwoofer is equipped with both speaker-level and linelevel inputs. Use the RCA/Phono” type INPUT jacks when connecting your subwoofer to a pre-amp, signal processor, or line-level crossover. TheSPEAKER“ LEVEL INPUT jacks” connect directly to the speaker outputs of an integrated amplifier or receiver. Your amplifier section will notice no additional loading effects when you use these inputs because of their high impedance.
Note:
Do not use both the RCA/Phono “INPUT” connections and “SPEAKER LEVEL INPUT” connections simultaneously.
Low-Pass Crossover
Both sets of inputs sum the left and right channels together and the resulting signal is passed through an adjustable low-pass crossover before being amplified. The crossover control allows you to adjust the upper limit of the subwoofer’s frequency response from 40 to 120 Hz. The subwoofer’s response will begin rolling off above the frequency you set this control to.
