Phase adjustment- 0˚ to 180˚

This control allows you to "delay" the phase of the subwoofer's output signal up to 180˚ to correct for any possible mismatch & resulting cancellation between the subwoofer and your main speakers/amplifier. To adjust, simply listen to the system with music playing. Then rotate the knob from one end to the other and listen for a change in low frequency output. The correct position will have a greater amount of apparent low frequency output.

Auto turn on function

With this function in the "auto" position, your CHT-15 can be safely left with the main power switch on continuously. The subwoofer will turn itself on automatically when an audio signal is present. If no signal is present for approximately 10 minutes, the unit will switch to standby mode. While in standy mode, your subwoofer will draw very minimal power. This function can be disabled by leaving the switch in the "on" position.

High pass crossover switch

This switch selects the frequency for the high pass crossover. This crossover is functional on both line-level and speaker-level outputs. Smaller speakers with limited low frequency output may prefer the higher 100Hz setting which will reduce the low frequencies sent to them. Larger speakers with greater low frequency output may be able to handle the 80Hz setting without strain.

Power switch

The master power switch is located on the right half of the unit. This rocker style switch is the main on/off for the unit. This switch should be set to position 1 for on (up), 0 for off (down).

Line-level connection

Figure 1, on page 5, shows connection to a pre-amplifier's main outputs and returning them to your amplifier inputs.

When installed in this fashion, your satellite speakers will be crossed over at 80/100Hz which removes the lower bass from your amplifier and speakers, enabling them to do a better job reproducing high frequencies.

This featured driver is capable of reaching frequencies as low as 18 Hz, effectively handling the most demanding audio tracks with ease.

One of the standout aspects of the CHT-15 is its use of advanced digital signal processing (DSP) technology. This ensures that the audio output is optimized for the specific acoustic environment, allowing for clear and precise sound reproduction without distortion. The built-in amplifier delivers 400 watts of continuous power, with dynamic peaks reaching up to 1000 watts. This ample power translates into impressive volume levels, ensuring that even the most action-packed movie soundtracks are dynamic and immersive.

The cabinet of the CHT-15 is designed with performance in mind, featuring a braced enclosure that minimizes vibrations and resonance. This construction enhances the overall sound quality, allowing for deep bass notes that are tight and well-defined. The subwoofer’s finish is both professional and appealing, allowing it to seamlessly blend into any home décor.

Connectivity options on the CHT-15 are versatile, including line-level RCA inputs as well as speaker-level inputs. This makes it easy to integrate the subwoofer into a wide range of audio systems, whether you're using it with a surround sound system or a high-end stereo setup.

Moreover, its patented "automatic room adjustment" technology measures real-time characteristics of the listening environment and adjusts the subwoofer’s performance to ensure optimal sound quality. This innovative feature sets the CHT-15 apart, making it a user-friendly option for those wanting professional-grade sound without the technical complexities usually associated with such systems.

In summary, the Velodyne Acoustics CHT-15 subwoofer combines robust engineering, cutting-edge technology, and outstanding performance features.
