CHT-Q Series User's Manual . www. velodyne. com 6 (2) 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. IR INPUT This is a connection that allows the utilization of a third party infrared remote sensor, such as Elan or Xantech, or an extended cable for placement closer to your other remote controlled equipment. This keeps you from awkward control angles using the infrared remote control. LINE OUTPUT Connect these jacks to the LINE IN preamp input to use the DEQ-R's internal high pass crossover. The signal fed from these connectors is rolled off below 120 Hz. LINE INPUT/LFE 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 the "L" ­ LFE input or, for more signal, use a "Y" connector (not included) and feed the signal into both "R" and "L" inputs. (3) (4) (5) AUTO ON/OFF Switch Use this switch to select between "stand-by" mode (woofer shuts off after eight minutes) and "always on" operation. 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, set the level while watching the LED display for reference. (6) Note: Volume is also controllable by using the supplied remote. The LED on the sub will show 00 if the unit is muted. To unmute the subwoofer, press the MUTE button again and the original volume setting shows on the LED. Figure 6: CHT-Q Remote. · EQ -- This button automatically equalizes the subwoofer's output so that it sounds best for its position in the room. To use this feature, remove the grille and plug the supplied microphone into the Mic-In jack on the front baffle of the sub and place the mic in your preferred listening position. Then press EQ on the remote for about 2-3 seconds. The subwoofer emits 12 "sweep tones" that span the frequencies between 20 and 150 Hz. The LED displays "AU" during the Auto-EQ process. After the sweeps are complete, the unit saves its EQ settings and returns to normal operation. To prevent accidental invocation of the EQ feature, you must hold down the EQ button for 2-3 seconds before the EQ sweeps begin. If the mic is not plugged in, the subwoofer sweeps twice then reverts back to normal functioning without changing any EQ settings. · PHASE -- These buttons allow you to optimize the subwoofer's bass performance relative to the speakers and your listening position. While listening, push one of the four phase buttons, listen for a few moments, and then press the next phase button. [. . . ] Under more serious conditions, the unit may shut off completely. Normal operation should return upon cooling, but you may be required to turn the power off and then on again to reset the unit. The following conditions require service by a qualified technician: 1. The unit does not appear to operate normally or exhibits a marked change in performance 3. [. . . ]
