If your main speakers are smaller with limited low frequency output, you may wish to choose a higher frequency (such as 100 - 120 Hz) than you would with larger speakers which have greater low frequency output. The default crossover setting is 80 Hz. With larger speakers, you may want to set this even lower, for example 70 Hz. Phase Adjustment - 0°/90°/180°/270° This control allows you to change the phase of the subwoofer’s output signal to correct for any possible mismatch and resulting cancellation between the subwoofer and your main speakers/amplifier. To adjust, simply listen to www.velodyne.com CHT-Q Series User’s Manual - 3... - Page 10 If the Sub-Out channel signal level from your receiver is too weak, this feature will not operate properly and shut the subwoofer off while you are listening to it. To correct this, see the VOLUME CONTROL section on previous page. 4 - CHT-Q Series User’s Manual www.velodyne.com...

(1) 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. 6 - CHT-Q Series User’s Manual www.velodyne.com... - Page 13 Use this knob to select the frequency above 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 120 Hz. Rear Panel Connections — Detailed Explanation Your new subwoofer is equipped with both speaker-level and line-level inputs. Use the RCA/Phono type “INPUT” jacks when connecting your subwoofer to a pre-amp, signal processor, or line-level crossover. The “SPEAKER 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. www.velodyne.com CHT-Q Series User’s Manual - 7...

With larger speakers, you might start with this control set lower, such as 70 Hz. Subwoofer Direct Subwoofer Direct is a setting on the low-pass crossover knob and will allow frequencies up to 120 Hz into the subwoofer.

Page 15: Crossovers
CROSSOVERS Receiver/Processor Subwoofer Outputs The Velodyne subwoofer is designed to operate using the full range audio signal for input when using the built- in crossover. Many home theater processors/receivers (Dolby Digital™, DTS™, THX™) have a “subwoofer out” jack (sometimes labeled “LFE”) that is internally filtered, settable at the receiver/processor, and designed to be used with a powered subwoofer. In some installations, it may be beneficial to use BOTH the Velodyne crossover and the receiver/processor crossover, resulting in a steeper ultimate crossover slope. In some rare cases, combining both an external crossover and the one internal to the subwoofer may result in low output and increased noise. - Page 16 SUBWOOFER OUTPUT JACK FRONT AMPLIFIER REAR Figure 4.
