Velodyne CHT-12 Subwoofer Questions & Answers
CHT12 speaker cuts out randomly have to turn off
Here is something you can try.
On your source check the output level for your sub.
Try setting up at a higher level, if at 1 set it for 2 or 3
Then adjust the volume control on the sub down to mach the speaker volume level.
Sub seems to not get louder with volume increase.
Try adjusting the frequency cut off of the sub and also play with the gain control on the sub. Turn your system up to where your front speakers are sounding as you like. Then try adjusting the sub to match the fronts so you have a good balance and blend.

Velodyne Hgs- 15x
The driver has a soft foam rubber gasket behind it. It can act like glue on the driver.
Taking the driver out will tear up this gasket, always does, so don't worry about that.
You can try to lever the driver out. Use care not to scratch the baffle.
Sub-woofer does not turn itself on in 'Auto' mode (signal driven)
For the "auto on" problem.
These will sound very basic, please go with it.
On your signal source, make sure you have the sub set to on.
If you can adjust the output setting on your source, turn this up.
Adjust the volume setting on the sub lower to mach the volume of the main speakers.
You may need to make these adjustments a few times to get them working.
On the hum and noise problem
Check your power outlet for the sub, make sure the polarity is correct. I have found this to not always be right. Also what is on that same circuit. Things like the fridge can cause a lot of noise on the power line. Next check your connecting cables, are they of good quality? Are they running next to anything that may cause interference? Also check you connections to the signal source. Cable and dishes are known for ground problems.
